•
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.

EARTHING
•
The alarm must be connected to a good quality earth.
•
EARTHING points are provided both inside and outside the alarm enclosure. These EARTHING
points are identified with the Ground Symbol.
•
The internal earth connection must be used. The external terminal is for a supplementary bonding
connection and is used where local code or authorities permit or require such connection.
