[6.2.3] Sensitivity Tests
[6.2.3.1] MOD400 or MOD400R Test
After verification of alarm capability, use the MOD400R test mod-
ule with a voltmeter to check detector sensitivity as indicated in
the test module’s manual. The housing cover must be removed to
perform this test.
If test module readings indicate that the detector head is outside of
the acceptable range that is printed on the label of the detector, the
detector chamber requires cleaning per Section [7] of this manual.
[7] Detector Cleaning Procedures
Notify the proper authorities that the smoke detector system is
undergoing maintenance, and that the system will temporarily be
out of service. Disable the zone or system undergoing mainte-
nance to prevent unwanted alarms and possible dispatch of the
fire department.
[7.1] Air Filters
1. Turn off power to the system.
2. Remove and inspect sampling tube filters.
3. If filters are heavily coated with dirt, replace them with new
filters. If they are not heavily coated, use a vacuum cleaner or
compressed air nozzle to remove dust, then reinstall the filters.
