Introduction
The Defender Door Handle Alarm is a safety device to be used at home, work or for travel. The
alarm is designed to be hung on a metal door handle and has adjustable hanging cord size for
versatility. The alarm produces a 125dBs siren when someone touches or attempts to touch the
metal door handle. The siren will last for a short period; you will not need to silence the alarm.
Operation of the alarm
After hanging the alarm on the metal door handle, turn the alarm on by turning the control on the
side of the unit upwards. For maximum sensitivity turn to
•••
, for medium sensitivity turn to
••
, and
for minimum sensitivity turn to
•
. The red LED will illuminate and the alarm will be active. An exit
delay of 6 seconds will allow you to exit the door without the alarm sounding. To switch off the
alarm turn the dial to
0
.
Sensitivity control
The sensitivity required will depend on the composition of the door handle, the objects
surrounding the handle (such as keys, chains etc) and the size of the handle. You can test this by
setting to the lowest sensitivity and attempt to open the door after 6 seconds. If the siren sounds
before your touch the handle then this is the advised level. If not, try again at a higher level.
Battery installation
The alarm requires 3 x AAA batteries (supplied and fitted). Before use, remove the protective
plastic strip to activate the batteries. To change the batteries, you will require a small screwdriver
to unscrew and open the battery cover at the back of the unit. You can then replace the old
batteries, noting the polarity diagram below.
