5. Verify relay status LEDs DS29-DS31 are lit green, and DS32 and DS33
are off. (DS29 - DS33: Figure 3.6-1, Item, 5,)
6. If you have a White-Only System: After 6 seconds, Verify all Flash-heads
are flashing in sync and in Night mode (lowest brightness, ~1/8 second
duration bursts at 40 bursts per minute).
7. If you have a Dual (Red/White) System: Verify normal red night mode
operation.
(a) Verify that all Flash-heads are OFF
(b) Verify that all Red Lights are ON and flashing properly, and the Red
Light Controller does not indicate any alarms in the top-most Red
Beacons.
(c) Verify that LED DS36 (EXT RED READY) is lit green (See Item 10,
Figure 3.6-1).
8. If you have a Dual (Red/White) System: Perform the following steps to
check white night backup operation.
(a) Simulate a Top Red Beacon failure.
On a Honeywell 9LCA Series Control, this may be done with the B1
circuit breaker in the Control. Turn the B1 breaker off to activate
the 9LCA Beacon Failure Alarm, or toggle the breaker momentarily
to activate the 9LCA Flasher Bypass Alarm.
Other Redlight systems have different controls, and may require
removing Red Beacon power at the input power circuit breakers.
(b) Verify that the DS36 (External Red Ready) LED is OFF.
(c) Verify that the DS32 (Night/Red) LED is ON
(d) Verify that the DS33 (Backup) LED is ON
(e) Verify that all the Red Lights are OFF
(f) Verify that all Flash-heads are flashing in sync and in Night mode
(lowest brightness, ~1/8 second duration bursts at 40 bursts per
minute).
(g) Repair the simulated Red Beacon failure.
(h) Verify that DS36 (External Red Ready) LED is ON.
(i) Verify that the lighting system is still operating white strobes, and
not red-lights.
(j) Set the MODE switch to DAY. Wait for the Flash-heads to switch to
DAY mode (about 6 seconds). Set the MODE switch back to
NIGHT. Wait for the Flash-heads to switch to OFF mode (about 6
seconds).
(k) Verify normal red night mode operation per Step 6 above.
