The points will scroll with each key press to view the points on the list, but the points will not get acknowledged in the database.

2.1.10 Detection Operation

Smoke sensors shall be smoke density measuring devices having no self contained alarm set point (fixed threshold). The control panel shall determine the alarm decision for each sensor. The control panel shall determine the condition of each sensor by comparing the sensor value to the stored values. Alternatively, sensors with builtin microship analysing smoke density is equally acceptable.

The control panel shall maintain a moving average of the sensors' smoke chamber value to automatically compensate (move the threshold) for dust and dirty conditions that could affect detection operations. The system shall automatically maintain constant smoke obscuration sensitivity for each sensor (via the floating threshold) by compensating for environmental factors. The smoke obscuration sensitivity shall be adjustable.

The system shall automatically indicate when an individual sensor needs cleaning. When a sensor's average value reaches a predetermined value, a "DIRTY SENSOR" trouble condition shall be audibly and visually indicated at the control panel for the individual sensor. Additionally, the LED on the sensor base shall glow steady giving a visible indication at the sensor location. If a "DIRTY SENSOR" is left unattended, and its average value increases to a second predetermined value, an "EXCESSIVELY DIRTY SENSOR" trouble condition shall be indicated at the control panel for the individual sensor. To prevent false alarms, these "DIRTY" conditions shall in no way decrease the amount of smoke obscuration necessary for system activation.

The control panel shall continuously perform an automatic self-test routine on each sensor which will functionally check sensor electronics and ensure the accuracy of the values being transmitted to the control panel. Any sensor that fails this test shall indicate a "SELF TEST ABNORMAL" trouble condition with the sensor location at the control panel.



An operator at the control panel, having a proper access level, shall have the capability to manually access the following information for each sensor:

a) Primary status

b) Device type

c) Present average value

d) present sensitivity selected*

e) Peak detection values*

f) Sensor range (normal, dirty, etc.).

g) Values shall be in "percent of smoke obscuration" format so that the operator requires no interpretation.

At least 1000 individually identified sensors as well as conventional initiating device and indicating appliance circuits shall be supported within a single control panel.

For increased smoke detection assurance, all individually addressed smoke sensors shall be provided with alarm verification. Only a verified alarm shall initiate the alarm sequence operation.

2.1.11 LED Operation

The alarm LED shall flash on the control panel until the alarm has been acknowledged.

Once acknowledged, this same LED shall latch on. A subsequent alarm received from another zone after acknowledged shall flash the alarm LED on the control panel and the panel display shall show the new alarm information.

A pulsing alarm tone shall occur until acknowledge.

Once acknowledged, this same LED shall latch on. A subsequent alarm received from another zone after acknowledged shall flash the alarm LED on the control panel and the panel display shall show the new alarm information.

A pulsing alarm tone shall occur until acknowledge.

2.1.12 Alarm Verification

The activation of any system smoke detector shall initiate an Alarm Verification operation whereby the panel will reset the activated detector and wait for a second alarm activation. If, within one (1) minute after resetting, a second alarm is reported from the same or any other smoke detector, the system shall process the alarm as described previously. If no second alarm occurs within one minute the system is to resume normal operation. The Alarm Verification is to operate only on smoke detector alarms. Other activated initiating devices shall be processed immediately. The alarm verification operation is to be selectable by device.

The control panel shall have the capability to display the number of times a zone has gone into a verification mode.

Alarm verification zones shall have the capability of being divided into seven different groups whereby only two verification zones from a group will confirm the first activation and cause the panel to follow programmed alarm sequence.



2.1.13 Manual Evacuation

A manual evacuation switch shall be provided to operate the systems alarm indicating appliances. Other control circuits shall not be activated. However, a true alarm shall be processed as described previously.

2.1.14 Alarm & Trouble Conditions
