When the detector heads are fitted for retro-reflective
operation the alignment procedure is as for normal operation
but with an additional test as follows:
When the system is aligned and in operating
mode block off the reflector at the reflector
end. The detector should go into fault
condition. If the detector does not go into fault
condition then it is possible that the signal is
being returned, not by the retro-reflector, but by
some other reflecting surface.
5. TESTING THE BEAM DETECTOR
SET
The following tests must be carried out after the first
installation, after any maintenance, or after every fire or fault
alarm to ensure fail-safe operation of the Beam Detector Set.
Supplied inside the Control Box is an acetate test card (filter)
with black markings on it which is used to provide
obscuration of the beam during tests.
Note: After the tests have been performed this
acetate card should be held with the system log
book and not inside the Control Box.
5.1 SMOKE ALARM TEST
Proceed as follows:
a) Hold the test filter in the beam path
b) After approximately 9 seconds:
i) the Fire Relay contact operates (the relay
contacts will click once as it operates).
ii) the Fire alarm LED (red) on the front panel
will light.
c) Remove the test filter, the alarm will reset in
approximately 4 seconds (unless in latching
mode).

d) Reset the Beam Detector Set either by:
i) Moving the Test/Reset switch to OFF, then
ON and then OFF, or
ii) Disconnecting the power for 2 seconds, or
iii) Taking the External Reset terminal to 0 volts
for one second.
e) The Beam Detector Set is now reset and armed.
5.2 FAULT ALARM TEST
Proceed as follows:
a) Totally obscure the beam with an opaque
object such as a piece of card.
c) After about 10 seconds check that Fault LED
(LED 1) lights, and the fault relay contacts
change state.
d) Remove the Test Card obscuring the beam.
e) Check that the Beam Detector Set resets itself
automatically within 4 seconds.
f) Secure the front cover, the Beam Detector Set is
now reset and armed.
Note: After the tests have been performed the recorded
values should be held with the system log book
and not inside the Control Box.
