Operating the Detector
To be admitted to work with the detector, the personnel are obliged to have studied this manual
and to have a certificate of verification of knowledge of accident prevention regulations.
The detector is used along with a poling loop controller as a part of Orion ISS. To have more
information about operating the system, please refer to documentation for S2000M, Orion Pro
Software Suite, Sirius FACP, and the PL controller in use.

Troubleshooting
Table 2.3.3.1
Problem
Possible Cause
Solution
No LED indication
No power applied
Check the presence of voltage
between detector contacts 2 and 5
Indication is disabled for the
detector in the configuration of
the PL controller
Check the type of indication
control for the detector in the PL
controller configuration
No communications over the
polling loop
A disconnect between the
detector and the PL controller
Check the integrity of the cable
and jointing
The detector is too far from the
PL controller
Minimize the polling loop length
to the detector. The polling loop
length shall be as required by
specifications for the PL
controller.
Two or more addressable
devices in the polling loop
have the same address
Check whether the addressing is
correct
A Fault event has been received
Thermal resistor has failed
(open circuit or broken)
Check the thermal resistor
condition
Closing of thermistor contacts
(water ingress)
Dry the circuit board
Warning!
If sparks, fire, smoke, and / or smell of burning are found at the installation site of the
detector, this one must be de-energized and sent for repair
