The DS924iPET is a Passive Infrared (PIR) Motion Sensor designed to
detect movement in the interior of a structure by sensing the Infrared
energy emitted from the human body as it moves across the Sensor’s field
of view. When motion is detected the unit sends an alarm signal to the
Control Panel. The DS924iPET is a high performance PIR Motion Sensor
which uses advanced signal processing to provide outstanding catch
performance and unsurpassed false alarm immunity. The DS924iPET is
designed to ignore a dog up to 40 pounds, two cats and small rodents.

• Keep all sensors within 100 feet of the Control Panel. The 100 foot
distance recommendation is given as a starting guideline. The LM PIR
Transmitter has an open air range of at least 500 feet, but the installation
environment may influence this range.
• Mount the sensor so there is a reference point (such as a wall) at the
end of its detection pattern.
• Mount the sensor so that an intruder will most likely walk across the
detection pattern.
• Mount the sensor 6.5 feet above the floor.

required,
remove
the
rectangular knockout. Locate the small spring in the hardware kit. Hold
the PIR base so the battery is visible. Place the spring on the black plastic
shaft of the wall tamper switch just below the battery.
• Remove the wall tamper bypass jumper located next to the walk test
switch.
• Using the mounting plate as a template, mark the location of the required
holes on the mounting surface.
• For installation on drywall or plaster, drill a 1/8" pilot hole to determine if a
wall anchor is required.
• Mount on an insulated outside wall facing in.
• Mount on a surface which is rigid and free from vibration.
Don’t
• Secure the mounting plate to the wall with the #6 x 1" wood screws
provided.
• Mount in direct sunlight.
• Aim at air conditioners, heat vents, wood stoves, fireplaces, intermittent
heat sources, etc.
HINGE
• Aim at solar heated walls or uninsulated metal walls.
• Aim at normally moving objects (ceiling fans, pets over 40 pounds, etc.).
• Mount the sensor where it can be exposed to moisture.
• Mount in locations where the temperature may be outside the sensor’s
operating limits of +32°F to +120°F (0°C to +49°C).
• Mount in areas with large metallic surfaces (e.g. heating ducts) or electrical
wiring which may inhibit the sensor’s RF signals from reaching the
Control Panel.
