Page - 4 - D7292/12
PREPARATION
ENSURE THE SUPPLY IS OFF BEFORE COMMENCING INSTALLATION.
A. Check that you have the correct alarm to satisfy the system specification.
Gas group and temperature?
Audible or Visual alarm or both?
Supply voltage?
Sound signal selected ?
Strobe lens colour correct ?
Suitable mounting location ?
Cable connection and installation method ?
B. Location
•Select a suitable location for the alarm with regard to the area to be covered by the
sound or flash signal.
•The surface should be flat in the area of the fixings and the material suitable to carry the weight of the
alarm.
•For a sounder, the sound signal pattern is omni-directional and the sounder should be mounted with
the Horn at the top.
•For a strobe, the alarm should be mounted with the lens at the bottom and out of direct sunlight.
•In exceptional circumstances, the alarms can be mounted horizontally or for the strobe, with the lens
uppermost.
Do not mount the sounder with the Horn downwards.
•The cable must be connected to the alarm via a sealed component and this must be located adjacent
to the cable entries in the alarm body.
•Suitable sealing devices are a sealed threaded nipple or a sealed gland; the choice of device depends
upon the gas group applicable to the installation and on the chosen installation method.
•There are two entries to the alarm body and one or both may be used depending upon the number of
cable cores required by the system arrangement.
•It is preferable that the cable and its seal be fitted at the factory or approved workshop; however the
method for assembling the cable and sealed components is described below.
IMPORTANT
THE ALARM IS A PRECISION INSTRUMENT. TAKE EXTREME CARE WHEN HANDLING.
•Particular care is needed when removing or replacing components which form part of the flameproof
enclosure.
•Exposed joint surfaces must be protected and not have contact with dust or dirt, or be knocked against
any object.
•The end flanges must be fitted squarely and on no account is force to be used. The flange must not
be hammered, levered with a metal instrument or the fixing screws used to pull down the flange.
•With care and patience, it will be found that the flange enters the body without difficulty.
I. Combined Sounder/Strobe
It is recommended that the unit be stood upright in a cup-shaped base holding the strobe section.
Remove the Horn from the sounder flange by unscrewing the three self-tapping screws (pozi drive head) in
the dome of the Horn.
Unscrew the four socket headed screws, two washers and 'O' ring in the flange. (Socket head wrench 4mm
(5/32") across flats). These screws will not be fully tightened if the alarm is not a factory-sealed unit.
IMPORTANT: TAKE EXTREME CARE WHEN REMOVING THE SOUNDER FLANGE FROM THE MAIN
BODY.
DO NOT USE THE TRUMPET AS A LEVER.
•Unplug the pressure unit cable from the PCB assembly.
•The exposed joints must be kept clean of dirt and not damaged in handling.
•Lay down the sounder flange assembly to one side on a clean piece of the packing material.

Page - 5 - D7292/12
CABLE CONNECTION (ATEX ONLY)
•Cable entry hole(s) to accommodate any suitable ATEX certified flameproof cable entry device for gas
group IIB or IIC with or without the interposition of a suitable ATEX certified flameproof thread adaptor
and for which the cable is appropriate and suitable for the conditions of use.
Cable entry temperature may reach 70°C.
Cable entry devices must be ATEX certified suitable for either IIB for IIB gas group or IIC for IIB+H2
gas group. Any unused entry hole is to be closed using a suitable ATEX certified flameproof stopping
plug for gas group IIB or IIC with or without the interposition of a suitable certified flameproof adaptor
for gas group IIC (one Baseefa ATEX certified stopping plug is fitted by manufacturer as standard).
Suitable ATEX flameproof cable entry devices, thread adaptors and stopping plugs certified as
Equipment (not a Component) under an EC-Type Examination Certificate to Directive 94/9/EC may
also be used in the manner indicated above.
The terminals accept wires of 2.5 mm².
The PCB assembly may be lifted in its slide channels to give easier access to the terminals.
CABLE CONNECTION (IECEx)
•Cable entry hole(s) to accommodate any suitable certified flameproof cable entry device for gas group
IIB or IIC with or without the interposition of a suitable certified flameproof thread adaptor and for
which the cable is appropriate and suitable for the conditions of use.
Cable entry temperature may reach 70°C.
Cable entry devices must be certified suitable for either IIB for IIB gas group or IIC for IIB+H2gas
group. Any unused entry hole is to be closed using a suitable certified flameproof stopping plug for gas
group IIB or IIC with or without the interposition of a suitable certified flameproof adaptor for gas group
IIC (one certified stopping plug is fitted by manufacturer as standard).
The terminals accept wires of 2.5 mm².
The PCB assembly may be lifted in its slide channels to give easier access to the terminals.
SOUND SIGNAL SELECTION
•It is preferable if the sound signal selection is set at the factory or at an approved workshop.
•To make the sound signal selection, refer to the table of sound signals and the switch positions for the
chosen sounds (Page 8).
•Double check you have selected the correct switch positions for your chosen stage 1 alarm signal and
for your chosen stage 2 alarm signal.
•Check again before re-assembly of the alarm.
RE-ASSEMBLY OF THE ALARM
•Reconnect the pressure unit cable connection; make sure this is secure.
•Make sure the PCB assembly is correctly located in the slides in the body. Check that the flash tube
is clearly visible and centrally located in the glass dome.
•Re-assemble the sounder flange to the main body but take care that the pressure unit wire is not
trapped in the joint, across the edge of the PCB assembly or between the head of the earth screw and
the pressure unit.
•Check that the 'O' ring is properly fitted in the groove in the body.
•Take care when fitting the flange. This must be inserted squarely into the main body. Force must not
be used, with patience it will be found that the flange enters without difficulty.
•The screws must not be used to pull down the flange to the body.
•Each socket screw should be fitted with a lock washer, flat washer and an 'O' ring. The 'O' ring must
locate in the groove at the base of the counter bore. Screw down the socket screws tightly.
Note:
•If the alarm has been in service and/or the socket headed screws in the flange have been previously
tightened, it is advisable to replace the o-rings (Part No. GR0192) before retightening the screws.
•Refit the Horn to the Trumpet using the three self-tapping screws.
II. Sounder only
•The alarm may be stood on a clean surface on the flat base.
•The procedure should be followed as described for the Sounder/Strobe alarm above.

Page - 6 - D7292/12
III. Strobe only
•The alarm should be stood upright in a cup-shaped base, which holds the strobe lens steady.
•Remove the fixing screws, washers and o-rings in the base plate.
•Connect the cable via the entries in the enclosure to the PCB assembly using the method described
for the sounder/strobe alarm.
•Ensure that the 'O' ring is properly fitted in the groove of the body.
•Refit the base plate carefully, ensure the flange is squarely located in the enclosure and there is a
minimum gap between flange and body.
•Ensure each socket screw is fitted with a lock washer, flat washer and 'O' ring.
•Screw down socket screws tightly.
Lens Colour Change
•If it is required to change the lens colour of the strobe, it is necessary to purchase the required colour’s
strobe flange assembly from your supplier.
INSTALLATION
•Ensure that the mounting surface at the installed location is flat and suitable for carrying the weight of
the alarm.
•Remove the bracket, fixing screws and washers from the bag in the carton. Assemble the bracket to
the alarm body enclosure using two off hexagon head set screws(M6 X 16mm long), lock washers
and flat washers.
•Check that the bracket is tightly secured to the alarm enclosure. The fixings for the alarm to the
mounting surface are two holes (8.5mm (0.33in) on 75mm. (2.95in) centres.
•Suitable bolts (not supplied) for securing should be used.
INTERCONNECTION OF ALARMS
Alarms may be connected in parallel, that is, up to ten alarms with common supplies may be connected as a
single system loop. Both sets of terminals should be used to provide an 'in' and 'out' connection.

ALARM CONNECTION FOR TELEPHONE INITIATE
Connection is as per the diagram above. The supply is on all the time with the
Sounder and/or Flasher only working when a ring tone is detected on the telephone
input.
Note:- The Sounder will follow the ring tone whilst the the Flasher will remain flashing
only switching Off 4 seconds after the Telephone has been answered.
Not suitable for UL applications.
