Test Magnet (Model No. M02-04 - optional)

Place the optional test magnet against the cover in the magnet test area to activate the test feature. Did the LEDs latch on within 10 seconds, indicating alarm and annunciating the panel?

Reset the detector at the system control panel. Was the reset successful?

Direct Heat Method (Hair dryer of 1000 – 1500 watts)

From the side of the detector, direct the heat toward the sensor. Hold the heat source about 6 inches (15 cm) away to prevent damage to the cover during testing. Did the LEDs on the detector light when the temperature at the detector reaches the alarm setpoint?

Reset the detector at the system control panel. Was the reset successful?

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.
