30 Revision 4 – 1-7-2008 FTB 312-4
Manual Override: Fixed
Intensities
You may manually override automatic
intensity control (as when the manual
intensity override switch S2 is set to
AUTO), but only if no synchronization
line connects to other lights. Remove any
wire from external circuitry attached to the
master/slave interconnect terminals. Do
this either for temporary purposes (testing)
or for permanent operation at a fixed flash
intensity.
Daytime
Switch the Intensity Control Switch (S2)
to DAY
Night
Switch the Intensity Control Switch (S2)
to NIGHT.
PCB1 Indicator Lamps
See Section 1 for a description of LED
indicators on the PCB1 board for system
checkout.
Standard System
The following procedures check normal
operation.
1. Check Normal Daytime Operation:
Apply power to the system (pull the
plunger of the interlock switch or
switches outward to the service
position). Ensure that the manual
intensity override switch or switches
are set to AUTO and verify that the
daytime responses at each power
converter in the system are the same as
those shown in Table 3-2 for Daytime
operation.
• Note that the white light is flashing
at the daytime high-intensity.
2. Check Normal Nighttime Operation:
Place an opaque (blocks all light)
cover over the photocell and verify
that the white night responses at each
power converter in the system are the
same as those shown in Table 3-2 for
Nighttime operation.
NOTE
A minute may pass before the photocell
responds to the darkened condition
after power is applied.
• Note that the strobe is flashing at
the nighttime intensity. The strobe
does not flash if a red light system
is used.
3. Check Alarm Sensing: Remove
primary power and temporarily
disconnect the black wire on TB2.
Apply primary power and verify the
following:
• The light does not flash.
• The WHT ALM LED (I 8) is lit
after three missed flashes.
• The DAY ERR LED (I 7) is lit.
• The alarm circuit operates
according to installation
requirements.
4. Restore the Equipment After
Checking: Replace all disconnected
wires. Remove the cover that you
placed on the photocell. Ensure that
the manual intensity override switch is
in the AUTO position.
5. If Any Responses are Not Normal:
If any of the responses above are not
exactly as described, proceed to
Troubleshooting.
