Defender EL00147 Quick Start Manual Download Page 2

The Defender Shock/Contact Alarm is a dual function 
130dBs alarm. The alarm can be triggered when  
vibration is detected or when the door/window is open 
and the magnets are separated. The vibration function 
can be disabled so the unit will only trigger when the 
door/window opens. 

The alarm is for indoor use only.

The battery compartment is accessed from the back of 
the alarm by removing the screw at the base of the unit 
and pulling up the back cover. Insert 3 x AAA batteries, 
noting the correct polarity. When the last battery is 
inserted, the alarm will beep to indicate the batteries 
have been installed correctly. Replace the back cover 
and screw. The unit has a solar panel which helps 
to prolong the battery life of the unit; the batteries 
should last up to 18 months. It is recommended that 
the alarm is tested regularly. If the alarm sounds weak, 
the batteries should be replaced. The alarm has a low 
battery indicator located at the top of the alarm, if this 
is showing, the batteries should be replaced.
