1. Fire Alarm - General Requirements.
The contractor shall supply, install, test, connect and commission a high quality fast-acting electronic
Intelligent Addressable Fire Detection and Alarm System.
The fire detection and alarm system shall comply with the requirements of BS 5839 Part 1 A1:2002,
A2:2008 code of practice for system design, installation, commissioning and maintenance in and
around buildings.
The fire detection and alarm system shall be manufactured by an ISO 9001:2008 certified company
and meet the term and definition in BS EN ISO 13943 and the following shall apply:

The CIE (Control and Indicating Equipment) and peripheral devices shall be 100%

Date: 02/02/2011 Issue 02
Prior to placing an order for any equipment, the contractor shall submit comprehensive documentation
comprising of working drawings, catalogues, technical datasheets, descriptive literature of
components, maintenance manuals, etc, for the consulting engineer's study and approval.
The contractor shall be responsible for making provision to train and instruct the client's personnel in
the correct use, operation and supervision of the system, preferably prior to the handing over of the
project.
The contractor shall ensure prior to installation that the location of sounders indicated on the intended
design will achieve a minimum of 65dBA in all areas (75dBA in bedrooms) and to include any
changes / variations issued during the course of the contract and that all system components are
manufactured by one manufacturer.
2. System Description.
The fire detection and alarm system shall be designed to facilitate accurate identification of the source
of heat / smoke / fire in its early stages to minimize the occurrences of false alarms.
The fire alarm control panel shall continually collect and analyze the required device data to enable it
to make the final decision on whether a fire or fault exists by comparing the plotted patterns from a fire
sensor against known fire and fault patterns held in its memory. The operational principle of the
system shall be on a true Intelligent basis, and shall provide the facility to print the output from a fire
sensor over a period of time or to transfer the data electronically to a PC for storage and analysis.
All system components and devices shall be connected to two core addressable loop circuits (as
shown in the typical schematics) with each component having its own individual inbuilt isolator.
Removal or disconnection of any component from the loop shall not affect the functioning and
performance of other components and the system. Please note that the use of group or zonal
isolators which are used to isolate a section of a loop in case of a cable fault is not acceptable.
The system shall be of Intelligent addressable type, i.e. all the devices on the loops of the FACP shall
be allocated addresses automatically from the panel at the time of system power up on a sequential
‘numerically lowest unused’ value basis (algorithm) and also given an address during commissioning,
the value of which shall be stored in non-volatile memory, within the electronics module of the device.
This value shall be interrogated during loop allocation and provided it is verified as being valid it shall
be used to set the device primary address.
Inntelligent system protocol Addressing shall include the benefit of Soft Addressing and also
overcome the limitations of Hard Addressing procedures.
If devices are added or removed at a later point, all the existing devices in the loop must keep
the same address, zone and text location.
The Control Panel shall allocate the addresses in strict sequential order when the loop is powered up
in order to speed up commissioning and ensure that it is impossible for two devices to have the same
address.
The Fire Detection and Alarm System, MUST have the capability for both soft and hard addressing
and should it be required, a hand held programming tool must be available to allow an optional
manual method of device setup and interrogation.
Date: 02/02/2011 Issue 02
Fire Detection and Alarm Systems which rely only on soft addressing or hard addressing
techniques, are not acceptable.
The fire alarm control panels shall be of a modular design complying with BS3116: Part 4 and facilities
shall be provided to constantly monitor and check the following circuits and fault conditions, and to
give the following features:

the power supply to the loop(s).


monitoring of all devices status to create a table of each analogue channel for event analysis.

all devices i.e., Optical/Heat Sensor, Fire Alarm Interface Units, Manual Call Points, Sounders
etc. shall be installed on the same loop and all interface operating relay / switch devices,
auxilliary relays (controlling remote plant items, door release units etc) be monitored for faults.

the FACP shall support loop powered and networked repeaters. Network repeaters shall have
a large interactive, touch sensitive, backlit, 320x240 viewable LCD screen. Repeaters shall be
programmable as passive (indication only) or active (indication and control) and must be
equipped with EN54-4 approved power supplies.

the addressable device Labelling procedure may be carried out either by using the inbuilt
touch screen display oft the FACP, by the use of a PC based dedicated software package or
by using a handheld programming tool for basic on-site programming.

all events, i.e. Fire, fault or warning, shall be recorded with time, date and place of
occurrence in the memory event log of the FACP. These events may either be displayed on
the control panel LCD display, transferred electronically to PC or printed, as required.

provision shall be available for the fire alarm control panel to silence the loop powered alarm
sounders but maintain visual indication until the system is reset.

the facility to introduce / change delay periods in operating loop powered individual sounders
or groups of sounders, shall be available to be programmed without the need to change any
hardware.

the facility shall be available to network up to 126 FACP’s using an international open
protocol bus system which must be compatible with Lon, Bacnet or Modbus.
Date: 02/02/2011 Issue 02
3. System of Operation / Cause and Effect.
Cause and effect procedures must be defined by the contractor either as a basic “one out all out”
or as a detailed evacuation procedure. Examples may include the following:
o
Stage 1: If a fire condition is detected in any area, only the local sounder (or group
of sounders) to operate.
o
Stage 2: If the alarm is not acknowledged within a predetermined time delay then all
sounders in the entire system to operate.
The Control Panel should have the facility for Alarm Acceptance timer T1/T2 programming in
order to allow acceptance and verification delays times to be set according to the evacuation
procedure requirements.
