RED ALARM LIGHT
Illuminates for 5 seconds whenever an Alarm message is being
transmitted to the SecurityGuard.
(There must be no movement in the room for at least 4 minutes
before an Alarm message will be sent).
Flashes when an Alarm is transmitted and the battery is low.
LENS
The lens directs Infra-red energy to the sensor inside the unit.
Keep the lens clean at all times.
DO NOT PAINT !
LOW BATTERY
The Red Alarm Light will change from a steady light to a
flashing light when the battery is low. SecurityGuard will warn
you when the battery is low and needs replacing. You should
replace the battery as soon as possible after the warning.
The PIR uses a special 9 Volt Lithium battery which should
provide a battery life of between 2 and 3 years. We recommend
you only use a Lithium battery as a replacement. The life of
other types of batteries such as Alkaline is several times less
than a Lithium.
Ultralife U9VL or equivalent.
COVER CLIPS
These are used to hold the cover of the sensor. To release the
cover of the sensor when changing the battery, use a small
screwdriver to gently lever the cover off the base to overcome
the clips. (see changing batteries)
INTERNATIONAL PIR
These are used to open the cover of the sensor. To release the
cover use the tip of a pen or a small screwdriver to depress
these clips

PIR detectors are able to sense movement by detecting small
changes of Infra-red energy in the area that they are looking
at. PIR detectors use special filters which are tuned to the
Infra-red energy produced by human beings, they use
advanced lenses to gather the Infra-red energy in a room and
focus it back to a sensor inside the unit.
S L E E P M O D E
Your PIR detectors are always active by scanning their area for
movement. To conserve battery life and to limit unwanted radio
transmissions the PIR waits until all movement in the room has
ceased for
at least 4 minutes
before it transmits an alarm
message to the SecurityGuard. Thus constant movement in a
room will not cause constant alarm messages to be sent and
battery power is conserved.
Note
- Although an alarm message is sent by the PIR, the
SecurityGuard determines if it should sound a siren or not
depending on whether it is Armed or Disarmed.

Infra-red energy will not pass through solid objects. Do not place furniture etc. in front of the PIR.
Do not place heaters or similar devices close to your PIR sensors, as the heat generates Infra-red energy and may
cause false alarms when you have ARMED your SecurityGuard.
