Resumen del manual
The cover of the controller contains the Alarm, Trouble, Dirty and Power LEDs. The cover of the sensor contains the Alarm, Trouble and Power LEDs. (See Fig 2.) The smoke detector can be reset by a momentary power interruption, by the reset button on the front cover, by the control panel, or by the remote reset accessory.

Disable the zone or system undergoing maintenance to prevent unwanted alarms and possible dispatch of the fire department. Cleaning Procedure 1. Disconnect power from the duct detector then remove the sensor’s cover. 2. Using a vacuum cleaner, clean compressed air, or a soft bristle brush, remove loose dirt and debris from inside the sensor housing and cover. (See Fig 12.) Use isopropyl alcohol and a lint-free cloth to remove dirt and other contaminants from the gasket on the sensor’s cover. 3. Squeeze the retainer clips on both sides of the optic housing then lift the housing away from the printed circuit board. 4. Gently remove dirt and debris from around the optic plate and inside the optic housing. 5. Replace the optic housing and sensor cover. 6. Connect power to the duct detector then perform a sensor alarm test. Recommended Service Schedule S Visually inspect each sensor connected to the controller upon installation and once every 6 months thereafter. S Perform a sensor alarm test on each sensor connected to the controller upon installation and once every 12 months thereafter. S Perform a sensor dirty test upon installation and once every 6 months thereafter or more frequently, as conditions warrant. Sensor Tests Sensor Alarm Test The sensor alarm test checks a sensor’s ability to signal an alarm state. This test requires the use of a SD-MAG test magnet. IMPORTANT: This test places the duct detector into the alarm state. Unless part of the test, disconnect all auxiliary equipment from the controller before performing the test. If duct detector is connected to a fire alarm system, notify the proper authorities before performing the test. To perform a sensor alarm test: 1. Hold the test magnet where indicated on the side of the sensor housing for seven seconds. Verify that the sensor’s Alarm LED turns on. 2. Reset the sensor by holding the test magnet against the sensor housing for two seconds. Verify that the sensor’s Alarm LED turns off. Sensor Dirty Test The sensor dirty test provides an indication of the sensor’s ability to compensate for gradual environmental changes. A sensor that can no longer compensate for environmental changes is considered 100% dirty and requires cleaning or replacing. This test requires the use of a SD-MAG test magnet. To perform a sensor dirty test, hold the test magnet where indicated on the side of the sensor housing for seven seconds. Verify that the sensor’s Dirty LED flashes. IMPORTANT: Holding the test magnet against the sensor housing for longer than 7 seconds will put the duct detector into the alarm state and activate all automatic alarm responses. The sensor’s Dirty LED indicates the results of the dirty test as shown below. FLASHES DESCRIPTION 1 0 to 25% dirty. This is typical on a newly installed duct detector. 2 26 to 50% dirty 3 51 to 75% dirty 4 76 to 99% dirty Controller Tests Controller Alarm Test The controller alarm test checks the controller’s ability to initiate and indicate an alarm state. IMPORTANT: This test places the duct detector into the alarm state. Unless part of the test, disconnect all auxiliary equipment from the controller before performing the test. If duct detector is connected to a fire alarm system, notify the proper authorities before performing the test. CRSMK CR S M K CRSMK To perform a controller alarm test: 1. Press the controller’s test/reset switch for seven seconds. Verify that the controller’s Alarm LED turns on. 2. After performing a controller alarm test, reset the sensor by pressing the test/reset switch for two seconds. Verify that the controller’s Alarm LED turns off. Controller Dirty Test The controller dirty test checks the controller’s ability to initiate a sensor dirty test and indicate its results. To perform a sensor dirty test, press the controller’s test/reset switch for two seconds. Verify that the controller’s Trouble LED flashes. TROUBLESHOOTING Dirty LED Sensor’s Dirty LED is Flashing Clean the sensor assembly as described in Cleaning Procedure. Power LED Sensor’s Power LED is OFF 1. Check the controller’s Power LED. If it is off, determine why the controller does not have power and make the necessary repairs. 2. Check the wiring between...
