NOTICE
If the functions alarm BIT and/or auxiliary BIT are set to YES, alarm

To perform a manual BIT:
Momentarily connect terminal 3 with terminal 2 or switch across

these terminals in the safe area.
If the status LED flashes green at 1 Hz, the test was successful.
If the status LED flashes yellow at 4 Hz, the test was not
successful.
If the BIT was not successful, it is then automatically performed
every minute. This continues, until a successful BIT occurs and the
flame detector resumes normal operation. The fault indication
remains until power is disconnected from the flame detector. The
fault indication returns if the fault is still found when power is
restored.
