7.2 Reset
Note : This is available only when the optional latched alarm has been
selected.
To reset a detector when in it is in alarm state, disconnect the power.
7.3 Functional Testing
The detector can be tested for proper functioning using the Flame Simulator
Model FS-1100.
7.3.1 Testing with Flame Simulator Model FS-1100
Refer to Flame Simulator FS-1100 instructions on page 59.
This test simulates an 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.
Important : If the detector is exposed to a flame simulator, the
alarm relay and 0–20mA will be activated during the simulation.
Therefore, automatic extinguishing systems or any external
devices, which may be activated during this process, must be
disconnected.
➣
To test with Flame Simulator Model FS-1100:
1
(If the detector is on, skip this step.)
Apply power to the system and wait up to 60 seconds for the detector to
return to the normal state.
The 1Hz LED flashes green.
Aim the SPECTREX Flam e Simulator Model FS-1100 at the target point of
the detector (see Figure 12), in such a way that the radiation emitted by
it is facing directly towards the detector. (See Flame Simulator FS-1100
on page 59)

Press the operation button once. After few seconds, the following occurs:
 The LED lights up red constantly for a few seconds.
 The 0–20mA output turns to 20mA for a few seconds, and then
returns to 4mA.
 The alarm relay also turns on.
This completes the installation procedure. The detector and system are now
ready for operation.
