3.1 KEYSWITCH
The Keyswitch is used to enable or disable the three control buttons. SOUND ALARM,
MUTE and RESET. The key can only be removed in the control disabled position, with
thekeyinsertedandturnedclockwisethecontrolsareenabled.
3.0 OPERATING CONTROLS
Thekey switchand threebuttons onthe frontof the CIEallows theuser andengineer to

The sounder mute push button is used to silence the system sounders and
theinternalbuzzerduringafaultcondition.Whenthemutebuttonispressed
during a fire activation the system sounders will be silenced but the internal
buzzer will sound continuously until the reset button is pressed. The mute
button is also used to silence the system sounders when the SOUND
ALARMbutton has been pressed. If themute buttonis pressedduring fault
condition the internal buzzer will cease to sound continuously and will only
bleeponceevery5seconds.LabelledonthePCBasS2Mute.
MUTE

from powering up. After a fire activation before the reset button can be
pressed the mute button must first be pressed, otherwise no reset will take
place. If reset button is pressed with or without a fault condition present the
CIE will re-initialize, illuminating all external LED's along with sounding the
internal buzzer for 3 seconds. The auxiliary supply to the zone terminals is
removed during the initialization period, resetting any smoke heads
connectedtothezoneinputs.LabelledonthePCBasS3RESET.

TheSOUNDALARM buttonis usedto activatethe soundercircuits, andcan
be used to evacuate the building, resound or test the sounders. Labelled on

4.7 MANUAL CALL POINTS
Call points should be sited with the following considerations, the rules below are mandatory.
1, On all escape routes.
2, On landings of stairways.
3, Near final exits to the open air.
4, Nobody has to travel 30 metres to reach a call point.
5, Call Points must be 1.4 metres above the floor and be free from obstruction.
4.10 SOUNDERS
Sufficientsounders should be installed so astoensurealarmaudibilityin all areas of thebuilding/
locationensuringafastandfullevacuation.Two sounderoutputsareprovidedontheCIE(Control
Indicator Equipment) allowing the connection of two independent sounder circuits, see BS 5839
Part1:1988section9.4fordetailedinformation.
1. Sufficient sounders should be installed to ensure sufficient dB levels around the premises
to aid a complete evacuation, even in the event of a failure of one of the sounder circuits.
75dB should be provided at the bed head of a sleeping person (With al doors closed). 65 dB
should be provided in all other working areas or 5 dB above any noise the re-occur for more
that30 seconds.
2. The minimum sound levels must be produced in all parts of the building / location. This
includes restricted area's that are infrequently visited, such as service ducts, store rooms,
toiletsorliftshaftmotorroomsetc.

4.6 AUTOMATIC 'POINT' DETECTORS
There are four common types of automatic 'point' detectors installed to aid the detection of fires
within a residential / commercial building. Ionisation and Photoelectronic Devices detect the
productsof combustion(smoke). RateofRise and fixedTemperatureDevicesdetectchanges
intemperature(heat).Opticalsmoke Devicesareusedfor,slowburningsmoulderingfires, iefor
escape routes and corridors, wood or cardboard stores, do not use in steamy, dusty or smoky
areassuch as kitchens andbathroomsetc.Ionisation SmokeDevices areusedforfast burning,
high energy fires, ie for petrochemical or solvent stores, electrical switch rooms. Heat Devices
are used when the environment is subject to constant levels of smoke or dirt, ie loading bays,
boiler rooms, kitchens, laundries and plant rooms. Fixed Temperature Heat Devicesare used
where high ambient temperatures exist, or in areas where sudden changes in temperature may
occur, ie near large windows or heat producing processes. Rate of Rise Devices have fixed
temperature operation, but also looks for sudden rises in temperature giving faster reaction than
standard fixed temperature detector. Sufficient detection devices should be installed to provide
adequateprotectioncoverage.
4.8 REMOTEINDICATORMODULE
Remote Indicator Modules can be used to remotely indicate the state of an automatic detection
device. i.e. there may be 10 rooms on a single corridor, if a single detection device were to alarm
eachroom would haft to be inspected, whichwouldtakevaluabletime.Aremoteindicator module
canbeplacedoutsideeachroomtoquicklyguideacorrectresponse.
4.9 AUXILIARY RELAY
The Auxiliary relay terminals can be used as a voltage free interface between the FIRETRAX
FT1BS/ FT2BS CIE. To such devices as magneticfire doorholding devices andcommunicating
devices to be connected to a phone line. The Auxiliary relay should be considered as a low
currentswitch,andshouldnotbeconnecteddirectlytomagneticdoorholdersandshouldonlybe
