Step 8. Install the Cover
Install the cover using the four screws. Be certain filters are installed as specified in Step 6. Make sure that the cover fits into the base groove and that all gaskets are in their proper positions. Tighten the four cover screws to 10
Step 9. Perform the Final System Check
Position the test magnet as shown in Figure 7. The LEDs on the detector should light. Any accessory LED(s) should also light and the system control panel should indicate an alarm condition.
Periodic Maintenance Requirements
Air duct smoke detectors should be maintained at least once a year – more often if the detector heads become obviously dirty. The detectors must also be cleaned imme- diately after a fire. Failure to properly maintain air duct smoke detectors may cause unnecessary false alarms.
Figure 9. RTS451/RTS451KEY Test Coil Installation:
It is recommended that a permanent Detector Test Log be set up and maintained, with a record for each individual smoke detector in each building. Each detector should be clearly described, with information on the type of detector, the model number, the serial number (if any), the location, and the type of environment. Data entries should include test dates, type of test mode, test results, maintenance, and comments. A Detector Test Log is included at the end of this manual.
Recommended Detector Maintenance Procedure NOTE: Notify the proper authorities that the smoke detec-
tor system is undergoing maintenance and will be temporarily out of service. Disable the zone or sys- tem undergoing maintenance to prevent unwanted alarms and possible dispatch of the fire depart- ment.
