Operation
When the power supply is applied, a green LED will flash to indicate power “ON.” After approximately 5 minutes, the
green LED will be illuminated permanently and the detector is operational. At alarm the LED will flash red/amber, the
buzzer will start and the relay will change status. In case of sensor fault, the LED will flash red with an amber pulse, the
relay will change status, and the buzzer will give a sound every minute.
