4. Interconnection Wiring. Correct interconnec-
tion wiring should be checked by disconnecting any
wire from the multi-conductor cable were it is con-
nected to the power or alarm circuit. The result, in an
approved wiring scheme, should be a trouble signal
indication at the control panel.
5. 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 stim-
uli and distances shown in Table 3. Fire response can be
checked by exposing the detector under test to a live fire
source. See Table 2. Follow all required precautions
when testing in this manner.
TROUBLESHOOTING
See Table 5.
MAINTENANCE
ROUTINE VISUAL INSPECTION
A properly installed PM-5MP 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 inspect-
ing 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.
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 list-
ed in the System Test section above.
WARNING
A full system test results in an alarm output. This
will result in the suppression system being activat-
ed if it is not disabled prior to testing.
