CDA-1 to CDA-8 Addressable Detection System

I. SYSTEM DESCRIPTION

I.1 Introduction

The Addressable Detection System is the result of the latest techniques in fire detection and is the natural evolution of the Identifiable Detection System towards equipment, which is not only able to identify the element causing the alarm (detector or button), but enables the total configuration of detection parameters (pre-alarm/alarm levels, sensitivity...) and also the adaptation of the unit to ambient conditions and to the ageing of the detector.

The Cofem Addressable Detection System is therefore an evolution of its predecessor, the Identifiable Detection System, with the added features of analogue detection.

Therefore the loop elements (detectors, buttons and relay modules) in the Cofem Addressable Detection System are self-coded, meaning that they can all be installed without the need for a prior manual codification, which helps tremendously in assembly and later modifications of the system.

I. 2 Operation principles

Analogue Detection Systems are based on the measurement and transmission of the instantaneous value of the controlled magnitude (concentration of smoke or temperature), which is then processed in the control centre, which determines the alarm or stand-by mode of the alarm.

Temperature and smoke concentration are transduced through the corresponding sensor into electrical voltages related to the magnitude measured (see figure 1).

After a linearisation process, a proportionality ratio is achieved between the measured

magnitude and the electrical voltage:

The main difference between conventional detection systems and the analogue system lies in the fact that in the former, the voltage delivered by the transducer is compared with a pre-set, fixed threshold value (Valarm), obtaining the mode of system stand-by or system in alarm from this comparison (see figure 2).

On the other hand, in the analogue detection system, , the value delivered by the transducer is constantly registered and processed, and it is possible to act on the detection parameters, such as the alarm threshold (see figure 3).

Figure 3. Adaptable alarm threshold in an Analogue Detection System

With this type of system, not only is it possible to vary the sensitivity of the detector, but it is also possible to adapt sensitivity to ambient conditions or to the loss of sensitivity associated to ageing of the sensor (figure 4).


In the Analogue Detection System used by Cofem, each detector transmits its

analogue value to the control station, every 8 seconds. The control station collects the readings of each detector and decides on its mode depending on the instantaneous readings, the previous readings (past), the programmed parameters and the decision algorithm.

Each detector incorporates a microprocessor to digitalise the analogue value read in the sensor, the transmission of this value to the control station and the identification of the detector.

Transmission of data is through a PWM modulation (pulse width modulation) which ensures high immunity from electromagnetic noise and possible degradation of line impedance. II- COMPONENTS OF THE ADDRESSABLE DETECTION SYSTEM

The Analogue Detection System is composed of detectors and other loop-related elements, together with the control station.


All loop-related elements in the Analogue Detection System are self-coding and

therefore do not require manual coding prior to installation. II.1 Detectors COFEM currently offers the following type of analogue detectors: SIHA: Analogue Ionic Smoke Detector STA: Analogue Temperature Detector II.1.1. Ionic Detector (SIHA)

The ionic detector measures the concentration of smoke particles per unit of volume present in the environment. If Y is the non-dimensional parameter proportional to the concentration of smoke, Y should be almost zero in clean atmosphere, increasing as the environment becomes contaminated.

The dynamic processing algorithms implemented in the control station, use values Ypre-alarm and Yalarm, as trigger levels of the Pre-alarm and Alarm respectively (figure 7). Both levels are pre-set at: Ypre-alarm = 40 Yalarm = 55

And can be manually modified from the central station.

Figure 7. Variation of the concentration of smoke with time. Pre-alarm and Alarm levels

If we define sensitivity of the detector as its greater or lesser capacity to detect concentrations of smoke, we can interpret the Pre-alarm as a highly sensitive measure in the concentration of environmental smoke. The Pre-alarm is used as an indicator of the sudden increase in smoke concentration, and when this exceeds the Pre-alarm Level for two or more consecutive readings, an optic and acoustic signal appears in the control station, which disappears as the concentration is reduced below the pre-alarm level.

When the concentration of smoke increases above the Alarm Level and stays there for two or more consecutive readings, the Alarm is activated (figures 8 and 9).

Figure 9: Prolonged variation in the concentration of smoke. The Pre-alarm and Alarm are activated

The Analogue Detection System registers changes in environmental conditions, by simply averaging the readings made during sufficiently long periods of time. This information is used to adapt the detector to slow variations in the environment, thereby avoiding the alarm from being unnecessarily activated. Figure 10 shows how the ionic detector displaces the Pre-alarm and Alarm levels as a result of slow increases in the concentration of environmental smoke. We see that the distance between the level Yenvironment (Yenvironment = 9, in total absence of smoke) and Ypre-alarm, and between this and Yalarm, they remain constant matching the values selected from the control station (figure 10).

Figure 10: Adaptation of Pre-alarm and Alarm levels to environmental variations.


Another phenomenon behind the increase in the concentration of smoke registered during prolonged periods of time, is a result of ageing of the sensor, meaning a loss of sensitivity. The adaptation operation described enables a constant sensitivity to be maintained in time, in spite of wear in the sensor, at least while the degradation of the sensor response is not Yalarm above Yalarm maximum, in which case the system will continue functioning but with a loss in sensitivity.

Through the central station, we can establish a Ymaintenance level , over which the system warns us that the sensor should be replaced or repaired (figure 11).

Figure 11. Adaptation of the Pre-alarm and Alarm levels to environmental variations and/or ageing of the sensor. The Addressable Ionic Smoke Sensor (SIHA) operation principle is based on the physical properties of an ionisation chamber. The variation of electrical features, in the presence of smoke, makes it suitable to be used as a smoke detector. It is a microprocessed and self-identified detector, conceived to be part of an Addressable Fire Detection System. The measure of the ambient concentration of smoke, it is transcript into a voltage value, which is digitised and transmitted to the Control Panel. SIHA detector is according EN 54 its part 7 normative with AENOR certification. The Addressable Optical Smoke Sensor (SOHA) operation principle is based on the Tyndall effect, based on the properties of in an optical chamber. The variation of electrical features in the presence of combustion aerosols, makes it suitable to be used as a smoke sensor. It is a microprocessed and self-identified detector, conceived to be part of an Addressable Fire Detection System.

The sensor element consists of an optical chamber provided with a light emitter and a receiver. In the absence of smoke, the intensity of the light captured by the receiver is null, because of the physical labyrinth created in between them. When exists presence of smoke, the reflection of the light in the particles, makes the receiver to obtain a certain intensity of light, (voltage value proportional to the level of darkness) everything controlled by a microprocessor, which also realises the communication with the Addressable Control Panel.


Also incorporates an static element which acts as when reaches 60ºC. Head an base, (interchangeable) are made in heat-resistant ABS plastic.

SOHA detector is according EN 54 its part 7 normative with AENOR certification. II.1.2. Temperature Detector (STA)

The temperature detector measures the room temperature together with its variation speed.

When the room temperature varies slowly (below 1ºC/min), the Pre-alarm and Alarm levels stay constant and equal to those pre-set from the control station (spot temperature detection). However, in the event of faster temperature variations (above 1ºC/min), the central station uses an algorithm capable of evaluating the temperature variation speed and setting the Pre-alarm and Alarm levels at different gradients (temperature thermospeed detection). In this way, a fast variation causes a decrease in the Pre-alarm and Alarm thresholds, thereby accelerating detection (figure 12).

Figure 12. Pre-alarm and Alarm levels in fast and slow temperature variations

Similar to what occurs with the ionic detector, the Pre-alarm level self-corrects itself with slow variations in room temperature, thereby avoiding false alarms. On the contrary, the Alarm level in these circumstances, remains constant and only changes with fast temperature variations.

Three sensitivity degrees can be selected for the detector through the central station (degrees 1, 2 or 3, according to standard EN 54-5).

The selected degree of sensitivity will depend on the room temperature where the detector is installed, and the pre-alarm temperature will adapt to the selected degree in each case.


In temperature detection, confirmation is also through two consecutive readings (8

seconds), prior to activating the Pre-alarm and the Alarm.

Head an base, (interchangeable) are made in heat-resistant ABS plastic.

SOHA detector is according EN 54 its part 5 normative with AENOR certification with sensibility degree 1.

II.2 Loop elements II.2.1. Master Detection Module (II-MA)

Module used as an interface to connect conventional fire alarm detectors and push-buttons with an addressable detection system.

In each II-MA is available to connect until 20 conventional detectors and/or push-

buttons supervising the line thanks to a 10uF/63V capacitor. Like this, we will know the line state, i.e. crossed line, opened line, detector alarm or push-button alarm.

In resume, the II-MA is an addressable element capable of communicating and

identifying itself with the control station. II.2.2. Analogue Alarm Button (PUL-ARA) Resettable push-button, microprocessed, able to communicate and identify itself with the control panel. Incorporates a visual indicator (LED) that switches on in manual use (alarm). The consumption of the push-button is 500µA at a voltage of between 24 and 40V. Maximum capacity of the loop for buttons is 32 buttons.

II.5 Master Relay Module (MDA-M2)

Two-relay switched module with 24V external supply, protected with a 2A fuse, which is installed as an any other kind of element of the loop.

Auxiliary power of 24V will be needed, to provide the required energy to the relay-controlled devices. These will be programmable independently (two functions) both in their type of application (siren, manoeuvre or extinguishing), and in their timing and the combination of detectors which activated then and are supervised. The voltage presence in the auxiliary 24V power line is also supervised.

The voltage provided by the relays output is 24V. In standby state, the MDA-M2 supervises the line by a 33Kohm resistor, that says if line is crossed or opened. Maximum capacity of the loop for relay-modules is 16 modules. II.6 Master Relay Module (MDA-M1)

Two-relay switched module with 24V external supply, protected with a 2A fuse, which is installed as an any other kind of element of the loop.

Two-relay module with only one function programmable for timing and combination detectors. One relay can be used for siren, manoeuvre, pre-alarm or extinguishing with a 24V output supervised with a 33Kohm resistor for crossed line or opened line. The second relay has the N/C and N/O function, not supervised, and with the electromagnet for fire against doors application as more used.

Maximum capacity of the loop for MDA-M1 relay-modules is 32 modules but it is important the consumption system for electromagnets. For more than 10 electromagnets, more supply sources are needed to install.

II.7 Technical Signals Module (MSTA)

Microprocessed and self-identified module installed as an any other element of the loop.

It has two inputs to differences the opened or closed state of a dry contact. In standby

state, the contact must be opened, if there is any trouble, the contact will be closed. The first input (marked as IN1) detects the contact closed as the ALARM state. The second input (marked as IN2) detects the contact closed as the FAILURE state. It is able a combination of both inputs at the same time having information for alarm and failure.

His typical application is shows the other detection systems states that could exist, to

connect flux detectors for sprinkler installations, switch detector in fire against doors, elevators, tank levels, etc.

Like this, we will monitoring the next trouble.


III.2 TYPE OF BREAKDOWNS There is three different types of breakdown according the power supply breakdown, detection breakdown and loop breakdown. The power supply breakdown are due to battery troubles as: Overload Battery Unload Battery Control Panel working with Batteries Battery Circuit A breakdown on the external 30 V battery is visualised as: Auxiliary Outout Breakdown The general siren output (R1, R2), thanks they are supervised, present the next trouble messages: Opened Siren Output G.1 or G.2 Crossed Siren Output G.1 or G.2 The possible Detection Breakdown Messages are next: Point doesn’t answer: Microprocessor breakdown shown on the scrren. Opened Line or Master Crossed Line: Means a breakdown occurs on the slave line. Opened or Crossed Line: Breakdown on the logic relay line. 24V Relay Breakdown: Opened line or burned fuse in relay master. There is four possible Loop Breakdown: Loop consumption: It means there is too much consumption (leaks, bad contact,...) Burned temperature fuse: Too much consumption on the loop.

Loop Controller Breakdown: Red led on the controller card ON or OFF permanently.

Power Supply Controller Breakdown: Loop controller has no power supply.


III.3 Alarm Types

Here are the possible alarm messages: SMOKE SENSOR ALARM TEMPERATURE SENSOR ALARM PUSH-BUTTON ALARM SLAVE DETECTOR ALARM SLAVE PUSHBUTTON ALARM

With an addressable-analogue sensor alarm, using the arrows, it is allow to move the cursor around the screen to visualise the detector data (type, number, point, label and serial number). Enclosed to the relays, the next messages can appear: ACTIVATED SIREN ACTIVATED MANOEUVRE EXTINCTION PRE-ALARM EXTINCION III.4 TC25/A Menu TC25/A Configuration and Information is available thanks to the windows menu we can access introducing an access code, after pressing any numerical key or RESET, ENTER, or ERASE keys. The different menus available in the TC25/A control panel are: Menu 1: MONITORING It allows visualise the different analogue-addressable sensors. Introducing the loop number and the point number, we can see the type of sensor (ionic, optical, heat), the situation label and the manufacturing serial number, on the firsts two lines of the display. In the smoke sensor it appears the alarm level (sensibility), read numbers done over the pre-alarm level and the alarm level in the tirad line of the display. In the last file there are the last five read values of the sensor and the smoke concentration average .


Loop Number: LABEL Point Number: Sensor type Serial Number: Sensibility: Alarm: Pre-alarm: Y(% smoke): --- --- --- --- --- Y amb.

In the SOHA, in the third display line appears too the Temperature Alarm counter (Al. Ter.: )

For the Analogue-Addressable Temperature Sensor (STA), the screen look is:

Loop Number: LABEL Point Number: Temperature Sensor Serial Number: Sensibility: Degree 1 Tamb.: Pre-alarm: T(°C): --- --- --- --- --- ---

Menu 2: MANUAL ACTIVATION RELAYS

There is shown three sub-menus: Activate Siren, Activate Manoeuvre and Activate Relays.

Once introduced into the sub-menus, we will be able to see the configured relay numbers according that sub-menu, the label and the state (ON, OFF). Then, with the cursor, in the relay we want to change the state, we push the buttons ON or OFF. Menu 3: GENERAL SIRENS

On the screen there are two sub-menus for the two general sirens configured in the TC25/A control panel. Once introduced in one of the two siren options, we can see the siren state and we will be able to change it with three options: Activate, Stop or Change delay. The trigger or stop of the siren is realised with the ENTER key.


Menu 4 : PROGRAMATION SYSTEM In order to entry into this menu, the control panel asks for access code (9000) and on the screen there are eight more sub-menus:

1.Revisar Historia : Se muestran en pantalla los siguientes submenús, a los que se accede por medio de los cursores (situación) y ENTER 1.History 2.Alarms 3.Breakdowns 4.Cancelled

It appears by inverted chronological order the different inquired troubles. Every screen is a trouble and using the cursors it will be visualise on the display.

The total number of recorded troubles is 99 (alarms, cancels and breakdowns) 2. Labels: There are three sub-menus in this option: 1. Points 2. Relays 3. Sectors Once situated on the point to put a label, appears a screen where we can see that for

each key is assigned a three letters and the number key. Pushing on to the key we can choose the letter we want. (Like the write way for

mobile phones). We will see the letter on the screen. The maximal characters per label is 20.


3. Configure: There are three options: 1. Loop configuration 2. Logic Relay configuration 3. Alarm Sectors configuration Going to the first option pressing enter we will have three new options: 1. Loop number 2. Loop configuration 3. Analogue sensibility configuration

With the first option, we can configure the loop number system. The second option (Loop configuration), has three more options: 1. See points configuration 2. Configure Points 3. Assign number to the point

The first option, once situates in the loop, indicates the loop

composition, (number of element and type). With the second option, we can get the actualisation of the loop composition.

The third sub-menu (Assign the number to the point) has two options: 1. Automatic assignation (Magnet) 2. Manual assignation

Once into the loop and selecting the element we want introduce the loop order number

there are two new options: Automatic mode: with a magnet and according point II.9 (Self-identification), when

we pass the magnet near the element, the LED will switch ON permanently. When the LED goes OFF, then the control panel already has assigned the order number corresponently

Manual mode: each element of the loop (sensor, switches, technical signal modules

and relay modules) has a serial number assigned that unmistakably identifies it. When manual assigning is done, this serial number must be entered, as requested on the screen. The point is then assigned.


The third sub-menu (Configure Analogue-Addressable Sensitivity) allows the

sensitivity previously established to be increased or lowered, once located in the point. The following sub-menus appear on the screen in the option Configure Logical

Relays:

1. Number of logic relays detected:___ 2. Configuration of a logic relay 3. Physical situation of the logic relay

Within this sub-menu, in any of this three options, the access code (9000) is requested

so that modificationscan be made or the relays programmed. The first sub-menu allows us to establish the number of logical relays in the system or

change this as required. In the second sub-menu, and situated in the relay, the following four options appear:

1. Relay type 2. Delay

3. Day / Night

4. Listed activation points

We can define the relay type in each one of these (Siren, Shunt, Extinction, Pre-alarm

or Conditioned), delay (minutes, seconds), activation (Day / Night) and the list of activation points.

It must be taken into account that up to six possible activation lists will come onto the

screen, while by PC there will be eight activation lists. The third sub-menu (Physical situation of the relay), shows, by means of the logic

relay number, which loop it is situated in, along with its number within the loop and its number in the corresponding relays master.

Situated in the third sub-menu Configure Alarm Sectors, the sector number is

requested and gives six configuration lists. When this is done with a PC, there are eight lists. 4. Set Clock Time: allows modify the year, month, day, hour, minute and second. 5. Set Day / Night: the control centre is programmed to the standard that the Day

timing is from 8 to 22 hours. For any other timing, the Start Day Time and End Day Time can be modified respectively in this sub-menu.


6. Set under test: by using this option, we can carry out maintenance work on the

detectors with auto-reset and without any relay being activated. 7. Printer Menu: If there is a printer, this allows it to be activated or deactivated. 8. Communications:

1. Control panel number___ 2. Repeater number ___ 3. Repeater program

The two first options indicate the number of control panel and the number of repeaters

that compose the system. Two possibilities appear on entering the third option. 1. Program all 2. Program label The first option asks for the repeater number and from this moment on, all the

information that the control panel has on the repeater is produced. It confirms good communication by means of continuous illumination of the Stop Sirens led.

The second option also asks for the repeater number and, whether it is a point, relay or

sector. Once the location is situated the repeater information is produced confirming good communication by the continual illumination of the Stop Siren led.

9. Blinking: asks for the loop number, and two possibilities appear on the screen. 1. Blinking permitted 2. Blinking inhibited Locate on the desired option, and operate using ENTER.

Menu 5: SET POINTS ON / OFF SERVICE There are two possibilities (ON / OFF) and the screen takes the element to the location (loop, point) in order to carry out the desired function. Menu 6: TEST ILLUMINATION OF LEDS MENU To check the illumination of all the LEDS of the buzzer and the face.


III.5 Access levels The TC25/A control panel fulfils all the requirements indicated in Regulation EN54/2. This regulation states that the control panel must have four differentiated levels of access. The four levels of access are: Level 1:

- Stop Buzzer

- Cursors

- No delay

Level 2 (two digit access code 27):

- All functions (keys) of the face

- Monitor

- Activation of Manual Relays

- General Sirens

- Set points ON / OFF service

- Test Illumination of Leds

From this level and in the presence of anomalies, press ENTER and the fast menu appears in the fourth line of the screen, with four options:

1. CANCEL 2. SERVICE 3. CHECK 4. MONITOR

Level 3 (access code of four digits 9000): According to the operation to be carried out, the same code is again requested.

- System Programming Level 4 (maintenance):

- Open control panel

- Modification and changing of cards, etc.

IV. INSTALLATIONAND START-UP IV.1 Installation The analogue detection system is installed in a closed loop and with all the elements of the loop (sensors, switches and modules) connected in parallel. Fig. 24 shows several examples of typical assemblies. Every element of the analogue detection loop is individually identified with a Serial Number assigned during its manufacturing process that differentiates it from any other element, even of its own types of element. During installation, the lists of the different elements assembled (sensors, switches, relay modules, technical signal modules) must be drawn up, indicating element type, loop, order number within the loop, label and element serial number. In this way, with the configured lists at work, and completed with the activation lists of the relays related to fire sectors, the system can be programmed from the office, with an external keyboard acting on the control panel itself. The CAS program on a PC can also be used, which later sends the information to the control panel.

Fig. 23 .- Arrangement of serial numbers IV.2 Start-up Once all elements of the system are installed (including control panel and batteries), it is put into function, checking that no anomalies appear corresponding to the status of the control panel.


From this moment on, each loop of the system installed is verified and configured in the following way: MENU------SYSTEM------CONFIGURE------LOOP------LOOP NUMBER In this way, we introduce the loop number in the system. Then we go on to the configuration of each of the loops, using this sequence: MENU---SYSTEM---CONFIGURE---LOOP---CONFIG. LOOP---CONFIG. POINTS

The control panel indicates the number of elements it recognises in, each of the loops, indicating the type (SIHA, SOHA, PULARA, MDA-M2, MDA-M1, IIMA and MSTA) and each one’s quantity. If the quantities and types correspond to those actually installed, this indicates that there are no installation problems (crosses, open lines...). Otherwise, an installation procedure must be followed to find the reasons why the control panel does not recognise all the elements installed. From here on, if the control panel has been programmed with an external keyboard, each element will have an assigned number in the loop, and the correct functioning of all the actions of the system checked. If the data entry of the system has been done with a PC, and the correct points configuration has been checked, a run-down of all the system programming must be done and all the actions for the correct functioning must be verified. If in this situation there still exists a sensor (detector) not recognised by the control panel, then a loop “MONITORING” can be carried out until find a point on the screen with the message “NOT DEFINED”. IV.3 Installation Extension When we wish to extend the installation with more elements, we have to go to CONFIGURE POINTS and check that these points are recognised by the control panel. We then go to the number of points added in the loop, by taking the following steps: MENU—SYSTEM—CONFIGURE—LOOP—CONFIGURE LOOP—ASSIGN Nº P. Assigning a number to the point can be done using an AUTOMATIC or MANUAL procedure. If we opt for the AUTOMATIC procedure, we then locate in the loop number and order number to assign, then energise the element with a magnet, bringing it near to the point of maximum sensitivity of the element as shown in Fig. 17 (section II.9). The LED remains lit until the control panel assigns it a point, when it goes out and the next element can be energised.


For MANUAL point assigning procedure, we locate in the loop and order number (within the loop), where we wish to situate the element number and a serial number is then requested on the screen. Enter this, and the control panel assigns the desired number automatically.
