4.3.1
Automatic BIT Test
Check that the indicators show normal conditions. See
on page 47.
4.3.2
Manual BIT Test
Caution:
If the function setup
alarm BIT
and/or
auxiliary BIT
are set to
Yes
(default is
No
), the alarm, auxiliary relay and 0
–
20mA outputs are
activated during a Manual BIT. Therefore, automatic extinguishing
systems or any external devices that may be activated during BIT
must
be disconnected.
To perform a Manual BIT:
Verify that the detector is in Normal Mode.
Initiate Manual BIT. The results of successful and unsuccessful manual BITs
are detailed in Table 11 and
4.3.3
Testing with Flame Simulator Model FS-1200
The Flame Simulator Model FS-1200 can be used to simulate exposure of the
detector to a real fire condition. The detector is exposed to radiation at the
required detection level. As a result, the detector will generate a Fire Alarm
signal. See
on page 69 for more information.
Caution:
If the detector is exposed to a flame simulator, the alarm and
accessory relays and 0
–
20mA are activated during the simulation.
Therefore, automatic extinguishing systems and any external devices
which may be activated during this process must be disconnected.
To perform a flame simulator test:
1
Power up the system and wait up to 60 seconds for the detector to turn to a
normal state. The Power LED turns on.
2
Aim the SPECTREX Flame Simulator Model FS- at the target point of the
detector (Figure 15), such that the radiation emitted by it is facing directly
towards the detector. (See
on page 69).
3
Press the operation button once. After few seconds, a successful test shows
the results listed in Table 17.
The detector is now ready for operation.
