load to the remaining UPS systems and go into a silent mode. This enables the

entire heat dissipation of this system to be nullified. This Silent system however

is On line electronically and will switch on as programmed in the event of a

problem with the utility or any other system. All this done without disruption to

the load.

- The IEM feature should ensure the following functions –

• Individual Inverters, which are not required to sustain the load can

automatically be switched off to save energy.

every UPS has the same amount of operating hours over a period of

time.

• During an inverter switch off due to low load the remaining selected

inverters should sustain the load.

• Customer to define if the rectifiers to remain ON for battery charging or

to be switched off for the UPS systems whose Inverters have been

selected to switch off.

• Customer to define after how long or at what Battery level rectifier

should switch ON.

i) Walk Test

j) Change alarm Verification.

Acknowledge keys shall also require privileged access to acknowledge points. If

the operator presses an acknowledge key with insufficient access, an error

message will be displayed. 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.

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

Page 137: Electrical Specification

AL TADAWI HOSPITAL PART B - SECTION 15

ANALOGUE ADDRESSABLE

FIRE ALARM SYSTEM

Page 8 of 25

(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.

LED OPERATION

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

acknowledged.

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.

MANUAL EVACUATION

panel front alphanumeric display. If more alarms or troubles are in the system the

operator may scroll to display new alarms. The system shall have an alarm list key

that will allow the operator to display all alarms, troubles, and supervisory service

conditions with the time of occurrence. This shall allow for the determination of

not only the most recent alarm but also may indicate the path that the fire is

taking.

1.0 SYSTEM DESCRIPTION

1.1 Description of Work

The contractor shall supply, install, test, commission and maintain during warranty period

the complete mobile radio system as specified herein for the hotel and serviced

apartment buildings.

The system shall be of the latest state of art technology in digital mobile radio system

and shall be based on DECT( Digital Enhanced Cordless Telecommunication)

technology or equivalent. Scope of work shall include the supply, installation, testing,

and commissioning of the whole system including but not limited to the following:

a) 30 nos indoor 6 channel base stations

b) 15 nos. outdoor 6 channel base stations

c) PC based management system for the subscription of the mobile phones and

programming the features.

d) Interface to the Property Management System

e) PC based Text messaging system

f) 80 Mobile Handsets

g) All related control, communication and power cabling, accessories and

terminations.

No. of base stations mentioned above are only indicative. Actual no. of base stations

shall be decided by the contractor based on a detailed site survey with all the required

advanced equipment. Contractor shall conduct the site survey and provide the

required no. of base stations at strategic locations to obtain complete coverage of the

area to consultant approval.

The contractor shall negotiate the necessary application for frequency allocation with

Ministry of Communication and shall be responsible to pay all the necessary charges to

Ministry of Communication.

The system should defines a Common Interface (CI) for equipment (between the Fixed

network part and the portable part)

The system supports both the Public Access Protocol (PAP), which has some proprietary

aspects and the Generic Access Protocol (GAP), which secures compatibility of the

system equipment of different suppliers for basic speech call. The latter allows the users

freedom of choice for the portable terminal equipment.

System should have micro-cellular system, which means that the system makes use of a

network of radios with a low transmitter power (250 MW). A cordless extension must be

registered by the system before it can be used to make or receive calls. This registration

process is called subscription. Subscription to the system requires a Personal Identification

Number (PIN) allocated by the Communications manager. Once subscribed the

extension can be temporarily removed, or blacklisted if required.

The cordless extension monitors the quality of the radio link during a call. If the

interference on a certain carrier (frequency) and timeslot causes problems, it should

switch to another frequency at that same base station. This is called intra-cell hand over.

This hand over procedure requires that the connection can be supported on 2 channels

simultaneously, for a while, to allow a "seamless hand over". So, first, the handset selects

Page 229: Electrical Specification

AL TADAWI HOSPITAL

PART B - SECTION 24

MOBILE RADIO SYSTEM

Page 4 of 10

a new (interference free) channel and sets up a connection via that channel, while the

old channel is still in use. Secondly, the old channel is disconnected. The user will not

notice anything of the hand over. If the mobile user roams from one cell to another,

during the conversation, he will probably go out of range of the first radio and into the

range of the second. In that case, if the quality of the transmission requires it, the radio

link will switch over to the new radio. This is called inter-cell hand over, which will also be

seamless.

1.2 Continuous Dynamic Channel Selection

The system handset should continuously monitor its environment and autonomously

selects the best frequency, timeslot and base station. This selection and possible change

should be unnoticeable for the user, when moving through the system network and

during a call. This process is called Continuous Dynamic Channel Selection (CDCS) .Due

to this CDCS process cells may overlap and no frequency planning is required, as is the

case for many other types of cellular systems.

Speech communication between handsets should be encrypted (or scrambled)

If a cordless telephone set is lost or stolen it should be possible for the communications

manager to blacklist the set. This means that can no longer be used within the DECT

area.

1.3 Frequencies and Timeslots

System should pirate in a frequency range of 1880 - 1890 MHz. There are ten carriers

defined and in each carrier 12 full duplex (12 up link + 12 down link) time slots. This allows

120 full duplex channels in the air. Frequencies and time slots are re-used in the covered

area and dynamically selected, so the maximum number of available channels always

high enough even in high traffic density areas. Due to the maximum number of duplex

time slots, the maximum number of simultaneous connections per RFP should be 6 or 12.

1.4 Radio Base-Stations

With a radio base station a radio environment (cell) is created in which the portable

telephone can operate. The radio base station should provide the air interface between

the fixed network and the portables.

The RFP is the radio base station or the Transceiver for the radio signals. The following

should be made available:

Indoor RFP that can handle a maximum of 6 simultaneous calls (6 channel RFP).

Indoor RFP that can handle a maximum of 12 simultaneous calls (12 channel

RFP).

If required Directional Antennas should be used to cover the required range.

1.5 PP (Portable Part)

The Portable Part of the system handset should be delivered with the iS Mobile system

comply with the GAP (Generic Access Profile), ETS 300 175 agreements.

1.6 Base Station

The Base Station should supports the following features

1.11 Text Messaging System

System should supports the following

DECT E2 Messages (up to 160 characters) supports up to 160 characters, the

DECT equipment and/or the handset may limit this to 128 or even 48 characters.

If the handset supports only 48 characters, the message can be chopped and

sent in parts to the handset.

Sending messages to the Digital extensions telephone of the PABX or DECT

extensions during ringing and in call connect status.

Message length can specified per device type. Also if messages are to long to

be displayed, they can be chopped into parts that can be displayed.

SMS messages to Cell phones.

The System should send SMS messages to cell phones. The interface to the Cell

Phone provider can be a modem or special box that behaves like a real cell

phone with SIM card.

This option is mainly used as alternative device. If a message to a DECT handset is

not acknowledged, the message can be forwarded to a cell phone.

E-mail messages.

E-mails can be sent via SMTP to any E-mail server. The E-mail contains the

message that needs to be sent.

Digital output to control relays or similar equipment.
