detection, the alarm needs to be installed at least 1.5m above the ground, 0.3m below the
ceiling and 1.5m from the corner of the room.

 Next to a window or a door.
 On the floor where unit may get kicked or damaged.
 Behind fans, air-con units or any sort of ventilation.
 Contained spaces such as inside a cupboard.
 Behind furniture or curtains, alarms must not be obstructed.
 Cold or hot environments. (no less than 0ºC or no more than 45°C)
 Dusty areas, this may block the sensor.
 Too close to an open flame, this can leave carbon deposits on the sensor, reduce its

sensitivity and give false readings.

 Directly above a heater or cooking appliance.
 Where a lot of moisture is present, e.g. bathroom or above a sink.
 Outdoors, this alarm is designed for indoor use only.
