22Fig. 30 — Typical Smoke Detector System WiringSensor and Controller TestsSENSOR ALARM TESTThe sensor alarm test checks a sensor’s ability to signal analarm state. This test requires the use of a field-provided SD-MAG test magnet.Sensor Alarm Test Procedure1. Hold the test magnet where indicated on the side of thesensor housing for seven seconds.2. Verify that the sensor’s Alarm LED turns on.3. Reset the sensor by holding the test magnet against thesensor housing for two seconds.4. Verify that the sensor’s Alarm LED turns off.CONTROLLER ALARM TESTThe controller alarm test checks the controller’s ability to initi-ate and indicate an alarm state.Controller Alarm Test Procedure1. Press the controller’s test/reset switch for seven seconds.2. Verify that the controller’s Alarm LED turns on.3. Reset the sensor by pressing the test/reset switch for twoseconds.4. Verify that the controller’s Alarm LED turns off.DIRTY CONTROLLER TESTThe dirty controller test checks the controller’s ability to initi-ate a dirty sensor test and indicate its results.Dirty Controller Test Procedure1. Press the controller’s test/reset switch for two seconds.2. Verify that the controller’s Trouble LED flashes.DIRTY SENSOR TESTThe dirty sensor test provides an indication of the sensor’s abil-ity to compensate for gradual environmental changes. A sensorthat can no longer compensate for environmental changes isconsidered 100% dirty and requires cleaning or replacing. Afield-provided SD-MAG test magnet must be used to initiate asensor dirty test. The sensor’s Dirty LED indicates the resultsof the dirty test as shown in Table 2.BDFEAC48TM500213 LCAUTIONOPERATIONAL TEST HAZARDFailure to follow this caution may result in personnel andauthority concern.This test places the duct detector into the alarm state. Unlesspart of the test, disconnect all auxiliary equipment from thecontroller before performing the test. If the duct detector isconnected to a fire alarm system, notify the proper authoritiesbefore performing the test.CAUTIONOPERATIONAL TEST HAZARDFailure to follow this caution may result in personnel andauthority concern.This test places the duct detector into the alarm state.Disconnect all auxiliary equipment from the controller beforeperforming the test. If the duct detector is connected to a firealarm system, notify the proper authorities before performingthe test.CAUTIONOPERATIONAL TEST HAZARDFailure to follow this caution may result in personnel andauthority concern.Pressing the controller’s test/reset switch for longer than sevenseconds will put the duct detector into the alarm state andactivate all automatic alarm responses.CAUTIONOPERATIONAL TEST HAZARDFailure to follow this caution may result in personnel andauthority concern.Holding the test magnet against the sensor housing for morethan seven seconds will put the duct detector into the alarmstate and activate all automatic alarm responses.
