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+H
2
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.

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.
