Changing the Batteries
Always use alkaline batteries or the correct type of coin cells as replacements because any
other battery can cause problems with the operation of the system. Typical life of batteries
is two years or more. Ensure the correct steps are taken when changing batteries in tamper
protected devices.
Control panel low battery
Indication
The control panel will display all device low battery
conditions with the exception of the siren. This is
shown by a fault display with the fault LED lit on the
front panel. In addition the devices also can show
low battery conditions as described below. When a
device first shows low battery signal it has enough
battery capacity to operate for a further month
before complete exhaustion.
Siren battery change
When the batteries start getting low the siren will
produce a series of pips and flashes during arming
and disarming.
1 Switch off tamper protection at the control
panel as described in section 4 'Mounting alarm
devices'.
2 Remove the siren lid and switch the siren power
switch to OFF.
3 Unscrew the four screws on the battery
compartment lid and remove the cover.
4 Remove the four batteries and replace them with
four fresh alkaline "D" cells.
5 Switch on siren power and check that the siren
beeps and flashes.
Warning: After the batteries have been changed
the tamper will become active again, either be very
careful when fitting the siren cover or switch off the
tamper protection again.
6 Replace battery compartment lid and screws and
reattach siren lid. Switch tamper protection back
on.
• Siren case tamper conditions are also signalled
by a series of beeps when the system is armed
but not when the system is disarmed (low battery
warning produces a series of pips when armed
and disarmed), take care not to confuse the two
different conditions.

PIR battery change
When the battery is low the LED will flash when any
movement is detected. The batteries are changed as
follows:
1 Put control panel into programming mode to
prevent a tamper alarm.
2 Loosen the case screw and remove PIR sensor
from base to reveal three AAA batteries.
3 Insert new alkaline batteries observing correct
polarity. The PIR LED will flash for 30 seconds
while initialising.
4 Refit sensor on base and tighten bottom case
screw. Switch tamper protection back on.
• PIR case tamper conditions are also indicated by
a flashing LED, check the tamper before changing
the batteries.
Door/Window Sensor battery change
When the battery is low the LED will flash when the
door/window is opened. The battery is changed as
follows:
1 Put control panel into programming mode to
prevent a tamper alarm.
2 Loosen the case screw and remove door/window
sensor from base to reveal battery.
3 Using a screwdriver gently lever out the old
battery.
4 Insert new CR2032 coin cell with the + side
uppermost.
5 Press battery into holder firmly with finger and
thumb until a click is heard.
6 Refit sensor on base and tighten bottom case
screw. Switch tamper protection back on.
• Door/window sensor case tamper conditions are
also indicated by a flashing LED, check the tamper
before changing the battery.
