showing the function of each terminal or by a terminal number. In the event of the terminal
number option being used, a permanent label must be mounted within the control equipment
showing the function of each terminal.
1.9.2
Essential Manual Controls
The system operation shall be simple to understand and shall not require the use of a
keyboard. Essential controls shall be clearly labelled to indicate both their function and their
method of use. Touch pad controls may be used to provide the essential control functions as
described in this clause, provided that their function can be ascertained without the use of an
instruction manual and provided that access is via an enable key switch or they are mounted
behind a lockable door.
Controls having more than one function are only acceptable if it can be shown that their use is
unlikely to lead to confusion or to delay in comprehension or operation.
Essential controls shall be grouped together and shall be distinct from non-essential controls.
Non-essential controls shall be hidden from view.
The following essential controls shall be available on each panel:(a)
A ‘System Reset’ Switch:
(i)
This shall be biased or momentary type so that it cannot be left in the reset
position, either intentionally or inadvertently. When in the reset position, a
non-silenceable fault warning shall be sounded. The action of this switch
shall be to reset any fire latch (providing the products of fire have cleared),
and to return the system to a quiescent state. Optionally this switch may also
reset any latched faults or alternatively a separate switch may be provided for
this function.
7
(ii)
(b)
It is permissible for the reset function to be provided by multiple switches,
perhaps on a zoned basis, provided the general requirements of this clause
are met.
An ‘Alarm Control’ Switch (or Switches):
(i)
An ‘alarm control’ switch shall be provided for each group of alarm warning
devices (alarms may be taken to be audible, visual or both). The switch (or
switches) shall provide the following facilities:



(ii)
Silence
Test alarm continuous
Test alarm intermittent
Evacuate
When an ‘alarm control’ switch is in the silence position, a non-silenceable
fault warning shall be given. Under no circumstances shall it be possible for
the alarm warning devices to be energised when the switch is in this position.
The operation of a ‘test alarm control’ switch shall not call the Fire Brigade or
switch off ventilation etc.
(c)
An ‘Accept Fire Alarm’ Switch:
(i)
The ‘accept fire alarm’ switch shall be of a biased type so that it can neither
intentionally nor inadvertently be left in the ‘accept’ position. When in the
‘accept’ position a non-silenceable fault warning shall be output. The function
of this switch is to silence the alarm warning devices when, and only when,
they are energised with the alarm control switch in the ‘automatic’ position.
The action of this switch shall be updating so that a fire signal from a
previously quiescent zone will cause the alarm warning devices to be reenergised. It shall be possible to repeat the silence and re-energise cycle for
as many times as there are zones on the system.
(d)
A ‘Fault Warning Silence’ Switch:
(i)
(e)
The ‘fault warning silence’ switch shall have an updating action so that even
though one or more faults have been accepted (silenced), a new fault will
cause the fault sounder to re-energise. When nominally silenced, the fault
sounder shall sound for a period of two seconds every two minutes.
‘Zone Isolate’ Switches:
(i)
A ‘zone isolate’ switch shall be provided for each zone of detectors or
sensors whether or not the zone is hard wired or software generated. The
switch shall have the effect of disconnecting all the detectors or sensors
associated with the zone in question, from the system. The switch shall be of
a type where it is possible to see which state it is in. When a zone of
detectors is isolated, a ‘zone isolation fault’ LED shall specifically identify the
isolated state of the zone in question, and a buzzer shall sound.
(ii)
The requirement for a ‘zone isolate’ facility is not intended to exclude the
isolation of detectors or sensors, on an individual basis. Where detectors or
8
sensors are individually isolated, an ‘isolation fault’ LED shall specifically
identify the isolated state of the device in question. The fault signal may be
displayed on a visual display unit specifically reserved for this function, in
which case there is no requirement for individual ‘isolation fault’ LED’s.
1.9.3
Indicating Equipment
The following indicating equipment shall be provided as a minimum on the panel:1.
Main Fire Indicator:
(a)
2.
3.
Fire Zone Indication:
(a)
Whether or not equipment such as visual display units, alpha numeric
displays or printers are included as part of the system, signals from each
zone of the system shall be specifically identified by the illumination to two
red zone fire LED’s per zone. Where there are no hard wired zones in the
traditional sense, software generated zones shall be employed to give the
same general type of indication. The zone LED’s shall be updating, such that
fire signals from previously quiescent zones come in as pulsing indications
until accepted, whereupon they become steady. Zone fire LED’s associated
with fire signals that have been accepted, shall remain steady until reset.
(b)
Zone fire LED’s shall be labelled by name/number so that the zone with
which they are associated can be identified.
(c)
Where indicated the zone fire LED’s shall be placed in a mimic floor plan.
(d)
Zone fire repeater panels shall be provided where indicated.
‘Power On’ Indication:
(a)
4.
A green ‘power on’ light emitting diode shall be included on the front panels
of all items of control and indicating equipment to show that they are active.
The light source shall be continuously illuminated under normal condition but
may be turned off or pulsed under mains failure conditions.
‘Main Fault’ Indication:
(a)
5.
The indicating equipment shall include a main fire indicator consisting of at
least two red LED’s that flash in response to new fire signals. When the
accept fire switch is operated, they shall change to a state of continuous
illumination but shall automatically revert to the flashing state in response to
fire signals from previously quiescent zones.
The indicating equipment shall include a main fault indicator that shall consist
of at least two amber or yellow light emitting diodes that flash in response to
new fault signals. When the fault warning silence switch is in operation they
shall change to a stage of continuous illumination but shall automatically
revert to the flashing state in response to fault signals from previously
quiescent circuits.
Subsidiary Fault Indicators:
9
(a)
Notwithstanding the possible presence of such items of equipment as visual
display units, alpha numeric displays or printers, faults from individual
monitoring circuits that are required either by other clauses in this guide or
BS 5839 and BS EN 54-2, BS EN 54-4, shall be individually identified by the
illumination of at least one amber or yellow LED. New faults shall cause the
appropriate LED to flash but when the fault warning silence switch is
operated, they shall change to a state of continuous illumination. Faults from
previously quiescent circuits shall not cause the fault indicators identifying
previously accepted faults to revert to the flashing stage.
(b)
All ‘subsidiary fault’ indicators shall be grouped together.
(c)
The function of each ‘subsidiary fault’ indicator shall be identified by a label.
The panel shall provide a facility to manually check all the discrete LED
indicators. This shall be clearly marked ‘Lamp Test’ and be accessible at all
times.
The panel shall be capable of accepting the following technical alarms as minimum:





Air Handling Plant
Gas Isolating Valves
Lift Monitoring Systems
Beam Detector Systems
Gas Extinguishing Systems
VESDA Detection Systems
The signals for the above shall be via interface units installed on the detection loops.
In addition to discrete visual indication, all indicating functions shall be shown on a
large character vacuum fluorescent and supertwist backlit LCD display at the panel
simultaneous with control operation. The display will, under normal quiescent
conditions, show the current date and time. In an alarm or fault condition, the display
will identify the panel, device loop, address and zone number, and a minimum of 40
character user definable location text.
Memory Devices and Fault Monitoring
The following requirements apply to the type and use of memory:(a)
The main control program and detection algorithms shall be held in non-volatile and
non-corruptible memory. The algorithms shall perform a trend analysis of the signal
received from addressable devices in order than non-fire events may be
differentiated.
(b)
Non-essential program information, such as the code necessary to drive graphics
displays, may be held on disc and down loaded into volatile memory, as required.
The panel shall include a hardware based monitoring (watchdog) circuit that is polled at least
once every 10 seconds
In the event of the circuit failing to be polled within the required time period, an automatic
hardware based restart procedure shall commence. If the restart procedure fails and the
watchdog procedure unsuccessfully attempts to restart the system three times, further restart
10
attempts shall cease and a hardware generated fault signal shall be annunciated at the main
control and indicating panel. The failure of outstation software control components need not
necessarily result in a watchdog restart procedure, but shall result in a fault signal at the main
control and indicating panel.
If two addressable devices have the same address, a fault warning identifying the shared
address shall be given.
If an addressable device is not of the type anticipated by the system configuration, a fault
warning identifying the device concerned shall be given.
All addressable devices shall be scanned at least once every 10 seconds. If a device fails to
response to three successive scans, a fault warning shall be given identifying the device
concerned.
A fault warning shall be given when the output of a sensor drifts outside its normal operating
range. The warning shall specifically identify the type of fault and the sensor concerned. It
shall be given before the extent of the drift renders the sensor non-functional for fire detection
purposes.
A special scanning sequence shall be available so that designated manual break glass
contacts provide alarm indication and warning within one second of operation.
The panel shall be substantially immune to the effects of electrical interference. This is to be
achieved to the satisfaction of the University by the use of such techniques as parity checking
and block bit counts. The system shall not take a decision on the basis of data received
before signals have been validated.
The system shall keep track of the numbers of errors detected and shall output a fault where
these continue for more than 20 seconds.
The Installer shall supply a description of the signalling protocol to be used on the proposed
system at the time of tender. Particular reference shall be made to the methods employed to
avoid data corruption.
No facility or control shall be provided by which the user can modify the stored program.
The University shall approve a limited list of the Installer’s personnel who will be authorised to
change the stored program. The names shall be entered in the Operation Manual.
No changes to the stored program shall be made without the written approval of the
University.
The University shall agree with the Installer a method by which person(s) authorised to modify
the stored program can be controlled. This shall be written into the Operation Manual.
Printers
Printers are not to be used as the only source of essential information, but where indicated
may be used as a source or supplementary information. As such they need have no standby
supply but, where fitted, shall produce fault warnings in response to the following
contingencies:(a)
Disconnection
11
(b)
(c)
(d)
(e)
Supply failure
Out of paper
Permanently busy
Out of ribbon (where appropriate)
Printers shall be wired with cable that is suitable for the purpose and is mechanically robust.
Where used plug-in connectors shall be fitted with retainers.
QWERTY (typewriter) keyboards (whether or not they are of the key or touch pad type) shall
be used only as a diagnostic tool and their use shall be restricted to approved engineers.
The following requirements apply to the use of QWERTY keyboards:(a)
(b)
(c)
They shall not be accessible to the operator.
They shall be accessed by a password.
They shall not be capable of modifying the control program or detection algorithm.
1.10.0 Power Supply and Batteries
Power Supply Design
Batteries and battery chargers shall be provided for the fire alarm panel.
Prior to the installation of the battery charger(s) and batteries, the Installer shall submit full
design calculations (to be subsequently included in the Operation Manual) showing that the
power supplies provided for the fire alarm and any associated systems will comply with the
British Standard requirements, under normal and mains failure conditions, when the following
factors are taken simultaneously into account:(a)
Battery capacity de-rated to a level that would be anticipated after 50% of its
operational life.
(b)
Battery temperature at the lowest limit that would be anticipated for the environment
in which it is to be situated.
(c)
