Testing the flame detector

1. Disconnect or disable external devices, such as automatic
extinguishing systems.

3. Perform one of the following tests:
Manual BIT (Dräger Flame 2000/2500/2700 only, see
page 16)

page 17)
4. Connect or enable external devices, such as automatic

Manual BIT (Dräger Flame 2000/2500/2700)
NOTICE
If the functions alarm BIT and/or auxiliary BIT are set to YES, alarm
relay, auxiliary relay, and 0-20 mA output are activated during a
manual BIT.
► Disconnect automatic extinguishing systems or any external
devices that may be activated during the test so that no fire
extinguishing measures are initiated.

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.
