Alarm:
This LED flashes when an alarm condition is detected and is also used as an
address indicator (see communication).
During an alarm condition, the Alarm LED is made to flash at approximately a 1 second
rate. The remaining four LEDs are illuminated as a coded sequence identifying the reason
for the lockout. For instance, for a LOCKOUT - FLAME FAIL- PTFI, the INTERLOCK,
PTFI and FLAME LED’s will all be lit steady, with the Alarm LED flashing. This remains
true if power is removed and then restored while in a locked out condition.
While in the Idle or Off state, the LEDs are made to flash sequentially every minute to show
the operational status of the control. The LEDs can be tested by pressing and releasing the
Reset push button, while in the Idle or Off state
