How it works:
The sensor is composed of two separate, equally important parts: the alarm unit itself, and
the trigger. The alarm unit is the larger of the two parts, and is responsible for sounding the
alarm (hence the siren). Inside the transmitter is a magnetically sensitive switch, which is
held in the OFF position by the magnetic trigger.
When the trigger is moved farther than approximately 1/2” (10-15mm) away from the door
sensor, the switch closes to the ON position and the alarm is triggered.
Arming and Disarming
The arming/disarming switch is located underneath the battery compartment, just above
the battery slot. There are only two settings, ON and OFF. Whilst ON, the alarm will sound
whenever the two parts of the alarm are separated. Whilst OFF, the alarm will not sound
under any circumstances.
• To arm the sensor, simply set this switch to ON.
• To disarm the unit or stop an alarm in progress, set the switch to OFF.
Mounting
Included are two portions of double-sided tape, one for both the alarm unit and the
magnetic trigger.
1. Remove the plastic cover from one side of the larger piece of double sided tape, and
apply the tape to the rear side of the alarm unit.
2. Remove the plastic cover from one side of the smaller piece of mounting tape, and
apply to the rear of the magnetic sensor.
3. Clean the surfaces you want to mount the alarm on using cleaning alcohol or similar.
Ensure the surfaces are completely clean and dry before proceeding.
4. Remove the plastic cover from the other side of the double-sided tape, and apply one
part of the alarm to the door/window you want to monitor, and the other part to the
frame. Ensure that when the door/window is shut, the small black arrows on the sensor
and trigger line up. They don’t need to physically touch, but they should be no more
that 1/5”(5mm) apart when the door/window is shut for the sensor to work correctly.
Replacing Batteries
1. Open the battery compartment on the front of the of the sensor.
2. Remove any old batteries.
3. Place four fresh alkaline LR44 batteries into the sensor. The correct orientation is shown
on the base of the battery compartment.
4. Use only alkaline batteries. Do not use rechargeable batteries.
5. To test the curret state of your batteries, press the TEST button, located in the battery
compartment. If the Battery Indicator LED will lights up then the batteries have enough
power to operate the alarm. If it does not light up or is dim, then you should replace
the batteries as soon as possible.
