Alarm LED flashes once per second, three times the normal rate. Wiring The terminal block accepts up to 12 AWG (2.3 mm) wire. Testing Internal diagnostic test These heads have moisture -proof reed switches that react to an external magnet for testing. The magnet test simulates a 4% to 6% smoke obscuration that places the detector in an alarm condition. This test results in specific LED and alarm circuit responses to indicate: • Detector within calibration standards • Detector settings outside sensitivity standards • Detector not operational This test is especially useful in environmentally unstable or unclean areas. Sensitivity voltage test These detector heads have a socket that accepts the D1005 Test Cable. The D1005 connects to the detector head and allows a voltmeter to read the sensitivity of the device. LEDs The D285 and D285TH have a built -in LED that flashes to indicate the device is powered. The LED latches on steady in an alarm condition.
