7.2 Reset
Note: This is available only when the optional latching alarm has been
selected.
To RESET a detector when in its ALARM state, disconnect power.
7.3 Functional Testing
The detector can be tested for proper functioning using the Fire Simulator
Model 20/20-310.
7.3.1 Testing with Fire Simulator Model 20/20-310
Refer to Long Range IR3 Fire Simulator on page 45.
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 must generate a Fire Alarm signal.
Important Note: If the detector is exposed to a fire simulator,
the Alarm Relay and 0-20 mA 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 Fire Simulator Model 20/20-310
1 (If the detector is ON, skip this step.)
Apply power to the system and wait up to 60 seconds for the detector to
turn to the normal state.
The 1 Hz LED flashes green.
2 Aim the Spectrex Fire Simulator Model 20/20-310 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 Long Range IR3 Fire
Simulator on page 45.)
3 Press the operation button once. After few seconds, the following occurs:
 The LED lights up red constantly for a few seconds.
 The 0-20 mA output turns to 20 mA for a few seconds and then
returns to 4 mA.
 The Alarm Relay also turns on.
This completes the installation procedure. The detector and system are now
ready for operation.
