Appliances for Private Mode use are intended to notify only those persons directly con- cerned with the implementation and direction of emergency action initiation and procedure in the area protected by the fire-protective signalling system.
The alarms are intended for connection to an alarm initiating and indicating circuit of a UL Listed control panel.
Models for connection to DC supplies have a DC line status monitoring facility.
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 correc?
Suitable mounting location?
Cable connection and installation method?
End-of-line alarm for dc monitoring?
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 en- tries 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 re- quired 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 as- sembling 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.
A. 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 (pozidrive 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.
Cable connection
The sealed threaded nipple or sealed gland should be assembled with suitable approved cable according to the manu- facturers instructions. The external cable should be routed to a local junction box, via approved conduit if appropriate.
Approximately 20cm (8 inch) tails are required inside the enclosure for connection to the terminals on the PCB assem- bly. The terminals accept wires of 14-18 AWG or 2.5mm². The PCB assembly may be lifted in its slide channels to give easier access to the terminals.
There are two entries to the enclosure; both may be used for cable connection via sealed threaded nipples if required.
Alternatively if only one entry is used for cable connection, the second entry must be fitted with an approved stopping plug.
The alarm is supplied as standard with the enclosure entries fitted with M20 to 1/2” NPT adaptors and one is fitted with an 1/2” NPT stopping plug.
The second entry is fitted with a dust cap. This must be removed and an approved fitting inserted before installation.
If the second entry is required, the approved stopping plug may be removed and discarded and a sealed cable fitting connected.
The adaptors form part of the approved flameproof enclosure and are locked in position. They must not be loosened or removed.
An alternative connection option is to fit an M20 to 3/4” NPT adaptor with an M20 approved stopping plug.
Only one sealed cable can be fitted with this option.
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.
Doubly 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. There must be a minimal gap between the flange and the body.
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 counterbore. 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.
B. 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.
C. Strobe only
The alarm should be stood upright in a cup-shaped base that 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 sound- er/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 be- tween 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 screw (m6x16mm), lock washer and flat washer.
Check that the bracket is tightly secured to the alarm enclosure.
The fixings for the alarm to the mounting surface are two clear holes9mm (0.35in) diameter on 75mm. (2.95in) centres.
Bolts (not supplied) for securing should be minimum length 25mm (1in) and 8mm (5/16”) diameter.
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; the loop wire should be broken to allow electrical supervision.
The “end-of-line” alarm may be fitted with a resistor across the supply connections to provide DC monitoring of the loop cable status at the control panel.
SYSTEM OPTIONS
Operating supply voltage 24vdc
Sound signal selections 32 (see table)
Alarm stages Single or Two from all sounders
Line monitoring DC By:
i) supply polarity reversal ii) threshold (<1V.) method
Strobe Separate terminals for independent supply connection of +24vdc and OV
For a combined sounder/strobe alarm, the +24 V DC and OV supply rails are linked on the PCB. If it is required that the strobe be supplied independently from an alternative supply but the OV can be common, remove the link “LK2,
+24vdc”. If a totally independent supply is required, i.e. both positive and negative, remove link “LK1, OV” also.
The location of the two links is shown on the drawings, Alarm Connection and Sound Signal Selection.
