TIME DELAY FOR AREA ALARMS
NOTE
Time delay affects the Area alarms only; the instant alarm operates as soon as a flame is
detected.
The time delay for the Area alarms is set using SW 5.3 to SW 5.7. If all of the switches are placed
in the ‘OFF’ position the time delay will be 0.5 seconds (minimum setting).
< SW 5.3-7: OFF: 0.5 sec. time delay
< SW 5.3: ON: 0.5 sec. time delay
< SW 5.4: ON: 1 sec. time delay
< SW 5.5: ON: 2 sec. time delay
< SW 5.6: ON: 4 sec. time delay
< SW 5.7: ON: 8 sec. time delay
If switch 5.8 is "OFF" then in Bypass mode:
- the current output is 4 mA
- the Fault Relay state remains unchanged (if it was energized, it remains energized; if it
was de-energized, it remains de-energized)
If switch 5.8 is "ON" then in Bypass mode:
- the current output is 3 mA
- the Fault Relay is de-energized
The total time delay is the added value of the switches turned ON. Switches can be turned ON in
any combination for a time delay from 0.5 to 15.5 seconds in half second increments. These
switches are factory set to a 3.0 second time delay as shown in the example below.
Example: SW 5.3 OFF time delay
SW 5.4 ON = 2.5 sec.
SW 5.5 ON
SW 5.6 OFF
SW 5.7 OFF
NOTE
SW 3.5 through SW 3.8 are not used.
RELAY SETTINGS
There are four relays on the controller circuit board that can be configured for normally OFF or
normally ON operation by moving the jumpers which are located below the relays. See
Figure 11c for the location of the relays on the circuit board and Figure 11d for the settings.
