one (1) or more coils are open, replace relay.
4.3.4.3 The time delay between an actual failure and the point
where the relay trips is pre-set at the factory or about eight
(8) seconds. This delay period can be tested by throwing
"on" (upward) switch number S1 (on the circuit board #1).
After testing return switch S1 to its normal (downward)
position.
4.3.5 False or Nonexistent Beacon Alarm (RF)
If alarm trips when the system appears to be working normally or fails
to show an alarm when there is an obvious failure, check relay K8 coil
for an open condition. Normal resistance should be around 2K ohm.
If coil is open, replace K8.
4.3.6 No Red Strobe Operation
4.3.6.1 Check if switch SW2 is on. If switch is off, turn switch to the
on position (upward). Reset the circuit breaker at the
service panel. If okay, go to the next step.
4.3.6.2 Turn switch SW1 to the on position (upward). On the
breaker at the service panel to the lights, turn off, then back
on. If the beacons comes on, then the unit fail-safes back
to the white back-up mode of operation, then replace the
failed red mode flashtube.
Note: Once the unit fail-safes, you will need to reset the
breaker at the panel in order to release the latched relay
in this circuit anytime a failure has been detected. This
is an important fact to remember when trouble shooting
this system.
