4.Test the detector using the magnet as described under
TESTING.
5.Reset the detector at the system control panel.
6.Notify the proper authorities that the system is back on line.
CAUTION
Dust covers are an effective way to limit the entry of dust into smoke detector sensing chambers. However, they may not completely prevent airborne dust particles from enter- ing the detector. Therefore, System Sensor recommends the removal of detectors before beginning construction or other dust producing activity.
Be sure to remove the dust covers from any sensors that were left in place during construction as part of returning the system to service.
CAUTION
Smoke detectors are not to be used with detector guards unless the combination has been evaluated and found suitable for that purpose.
Testing
Before testing, notify the proper authorities that the smoke detector system is undergoing maintenance and will tem- porarily be out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms. Detectors must be tested after installation and as part of periodic maintenance. Test the 2151 as follows:
NOTE: Before testing the detector, check to ensure the LEDs blink. If they do not, the detector has lost power (check the wiring) or it is defective (return it for repair).
A. Test Magnet (p/n
1.Place the magnet against the cover in the location designated by the raised mark to activate the test fea- ture (see Figure 1).
2.The LEDs should latch ON within 5 seconds indicat- ing alarm and annunciating the panel.
B.Test Module ( MOD400R)
Use the MOD400R with a DMM or voltmeter to check the detector sensitivity as described in the MOD400R manual.
C.Aerosol Generator (Gemini 501)
Set the generator to represent 4% to 5%/ft. obscuration as described in the Gemini 501 Manual. Using the bowl- shaped applicator, apply aerosol until unit alarms.
Notify the proper authorities that the system is back on line.
Detectors that fail these tests should be cleaned as described under MAINTENANCE and retested. If the detectors still fail these tests, they should be returned for repair.
Maintenance
It is recommended that the detector be removed from its mounting base to facilitate cleaning. The detector is cleaned as follows:
NOTE: Before removing the detector, notify the proper authorities that the smoke detector system is undergoing maintenance and will be temporarily out of service. Disable the zone or system undergo- ing maintenance to prevent unwanted alarms.
