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.
2
Aim the SPECTREX Flam
e
Simulator Model FS-1100
at the target point
of the detector (see Figure 16: Flame Simulator), in such a way that the
radiation emitted by it is facing directly towards the detector. (See
on page 57)
3
Press the operation button once. After few seconds, the following
occurs:
•
The LED lights up red constantly for a few seconds.
•
The 4
–
20mA output turns to 15mA 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.
