Interconnection Wiring.
Correct interconnection
wiring should be checked by disconnecting any wire
from the multi-conductor cable were it is connected
to the power or alarm circuit. The result, in an
approved wiring scheme, should be a trouble signal
indication at the control panel.
4.
Restore Fire Protection System.
Restore the
system to an operational condition after all tests have
been completed.
OPTIONAL TEST METHOD
With the detector powered up, the following tests can be
done. False alarm immunity can be checked using stimuli
and distances shown in the table in Appendix A. Fire
response can be checked by exposing the detector
under test to a live fire source. (See Appendix A.) Follow
all required precautions when testing in this manner.
TROUBLESHOOTING
See Table 3.
MAINTENANCE
ROUTINE VISUAL INSPECTION
A properly installed PM-5MPX detector system is highly
resistant to blinding by contamination build-up on the
detector front face window. However, a thick enough
build-up will begin to reduce the performance of the
detector. This can be prevented by periodically inspecting
installed detectors visually for contamination build-up on
the detector front face. If such a build-up is observed, it
should be removed by cleaning the detector front face
window with a soft cloth or lens tissue. The minimum
inspection period should be compatible with appropriate
regulating agency requirements.
WARNING
To prevent the risk of electrostatic discharge, the
surface of the detector should only be cleaned with
a damp cloth.
PERIODIC SYSTEM TEST
The authority having jurisdiction and internal facility
requirements generally call for routine testing of safety
systems at defined intervals, which, at a minimum, should
conform to the requirements of NFPA 72. These tests
should include visual inspections and the steps listed in
the System Test section above.

Symptom
Probable Cause
Corrective Action
Trouble signal at fire alarm control panel.
Incorrect wiring
Check circuit installation.
Low or no voltage to detector.
Check voltage of Red or Orange wire with
respect to the Black or Brown wire. Should be
9 to 30 Vdc.
Detector malfunction.
Replace detector
Detector does not alarm during FIRE
RESPONSE test with PSS-MP.
Incorrect wiring.
Check circuit installation.
PSS-MP temperature different from detector.
Allow detector and PSS-MP temperatures to
stabilize. Turn on PSS-MP at least 15 seconds
prior to test.
Low batteries in PSS-MP.
Replace batteries and retest.
Detector malfunction.
Replace detector.
Red LED out.
Incorrect wiring or incorrect power to the
detector.
Check circuit installation.
Detector malfunction.
Replace detector.
