INSTALLATION INSTRUCTIONS
Learn Mode (LM) DS924i /DS924iP
Wireless PIR Motion Sensor
A Passive Infrared (PIR) Motion Sensor is 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 DS924i/
DS924iP are high performance PIR Motion Sensors which use advanced
signal processing to provide outstanding catch performance and
unsurpassed false alarm immunity.

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, see Figure 1.
• Mount the sensor between 6.5 (2 m) and 10 ft. (10.7 m) above the floor.
(Between 3 (1 m) and 5 ft (1.5 m) for Pet Avoidance Lens).
• Mount on an insulated outside wall facing in.
• Mount on a surface which is rigid and free from vibration.
Do Not:
• Mount in direct sunlight.
• Aim at air conditioners, heat vents, wood stoves, fireplaces, intermittent
heat sources, etc., see Figure 2.
• Aim at solar heated walls or uninsulated metal walls.
• Aim at normally moving objects (ceiling fans, pets, etc.), see Figure 2.
• 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.
• Mount in areas where the coverage may be blocked by any temporary
items such as boxes or freight.
3.0 MOUNTING
Surface or Corner Mounting (without swivel bracket)
• Remove the sensor’s cover by gently inserting a screwdriver into the
notch at the bottom of the cover.
• Completely loosen the mounting base locking screw.
• Remove the mounting plate from the enclosure by prying it up and out
from the bottom.
• Punch out 2 appropriate holes in the mounting plate (for surface or
corner applications).
• If the wall tamper function is 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. NOTE: The wall tamper can not be used when corner mounting.

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.
• Secure the mounting plate to the wall with the #6 x 1" wood screws
provided.
• Skip to “Attaching the Enclosure."
Swivel Bracket Mounting
• Using the swivel bracket as a template, mark the location of the required
holes on the mounting surface.
• If not mounting in a corner, the corner mount tabs may be removed
(Figure 6).
• For installation on drywall or plaster, drill a 1/8" pilot hole to determine if a
wall anchor is required.
• Secure the swivel bracket to the wall with the #6 x 1" wood screws
provided.
• Attach the mounting plate to the swivel bracket using the #6 x 5/8"
machine screw provided.
• Aim the mounting plate in the desired direction and tighten the screw.
NOTE: The wall tamper switch can not be used when mounting with the
swivel bracket. Use of the swivel bracket may reduce range and dead
zones.
Attaching the Enclosure
• Attach the PIR base to the mounting plate and tighten the mounting plate
locking screw.
• Replace the cover, engaging the top first then securing the bottom latch.
• For added security, the cover may be locked to the base latch using the
small screw provided. The screw hole in the bottom of the cover must
be knocked out prior to replacing the cover.
4.0 Programming
General Guidelines
• Put the Control Panel in program mode.
• Trip the sensor’s tamper switch by removing its cover.
• Restore the tamper by replacing the sensor’s cover.
Refer to the appropriate Control Panel installation manual for specific
instructions on programming this device.
5.0 Walk Testing Setup
• If the correct lens is already installed, skip to the Sensitivity Selection.
• To change the lens, first remove the sensor’s cover.
• Remove the installed lens by grasping each side and pulling it away from
the lens frame.
• Replace with the appropriate lens by inserting the corners of the lens
behind the tabs in the lens frame.
• Install the new lens with the smooth side facing out and the grooved side
facing in.
• The notch indicates the top center of the lens.
• The coverage pattern may be aimed by moving the circuit board and/or
lens.
• Consult the pattern drawings on Page 4 and the following recommended
adjustment table.
6.0 Sensitivity Selection
• Locate the sensitivity pins. Move the shorting jumper to the appropriate
pair of pins.
• If the shorting jumper is not used or placed incorrectly, the sensor
defaults to Intermediate sensitivity.
Standard sensitivity is recommended for Broad coverage patterns.
This setting is the most tolerant of environmental extremes.
Intermediate sensitivity should be used for Long Range or Barrier
type lens patterns or for any location where an intruder is expected
to cover only a small portion of the protected area. This setting
tolerates normal environments.
High sensitivity should only be used in quiet environments
where thermal and illumination transients are not
anticipated. This setting has the fastest response to
intruder signals.

7.0 Testing
Pattern Testing
Pressing the Walk Test Switch will start a 90 second Walk Test Mode.
During this Test Mode, any activity in the sensor’s coverage pattern will
cause a transmitted alarm and LED activation. Each alarm will also extend
the Test Mode for an additional 90 seconds.
Walk Testing should be done across the coverage pattern. The edge of the
coverage pattern is determined by the first flash of the LED. This may
change slightly depending upon the sensitivity setting. Walk Test the unit
from both directions to determine the pattern boundaries.
NOTE: Excessive use of the Walk Test Mode may reduce battery life.
Use only for initial setup and maintenance testing.
If the rated range cannot be achieved, adjust the pattern up or down to
assure the pattern is not aimed too low or high. The vertical angle of the
pattern may be changed by adjusting the swivel bracket and/or by moving
the circuit board vertical adjustment between -10° and +2° . Loosen the
Vertical Adjust Screw to slide the circuit board. Moving the board up will
angle the pattern downward. Tighten the Vertical Adjust Screw when
positioning is complete.
The detection pattern may also be shifted ±10 degrees horizontally by
rotating the lens left or right to the appropriate marks on the lens frame.
RFTESTING
The actual RF transmitter range can be determined by performing a Dealer
Sensor Test as follows:
• Remove the sensor’s cover and press the Walk Test Switch. Refer to
Figure 3 for the switch location.
• Replace the sensor’s cover.
• Using the appropriate touchpad for the Control Panel, enter the Dealer
Sensor Test Code.
• Move across the detection pattern until the sensor’s LED turns on. STOP
your motion.
• Note the number of siren beeps indicating how many RF packets the
control panel received from the sensor. You should hear 7-8 beeps. If
you hear 6 or fewer beeps, relocate the sensor and retest.
Final Testing
Turn on all heating and air conditioning sources which would normally be
active during the protection period. Stand away from the sensor and
outside the coverage pattern and watch for alarms.
After setup and tests are completed, and there has been no activity in the
sensor’s coverage pattern for approximately 90 seconds, the LED will flash
to indicate that the Walk Test mode is ending.
NOTE: When the Walk Test Mode has ended, an alarm can be transmitted
only after three (3) minutes have passed since the previous alarm.
This 3 minute lockout time reduces unnecessary RF transmissions
in high traffic areas thereby extending battery life.
8.0 Maintenance
At least once a year, the range and coverage should be verified for proper
operation. To assure daily operation, the end user should be instructed to
walk through the far end of the coverage pattern to verify an alarm output
prior to arming the system.
Battery Installation
The sensor is normally shipped with its battery installed. If battery
replacement is necessary observe proper polarity when installing a new
battery or the sensor may be damaged. When the battery is replaced, wait
at least 5 minutes after installing battery before activating the Walk Test
Mode.
9.0 Pet Avoidance Lens Guidelines
The Pet Avoidance Lens provides protection in installations where pets
move about freely.
• Allowed mounting height is between 3 and 5 feet.
• Position the sensor to have a clear line of sight across the protected
room.
• For best results, install the sensor no lower than twice the height of the
pet.
• Make sure the field of view is free of furniture or other objects upon
which the pet could climb or jump, resulting in unwanted alarms.
Coverage Masking
The Masking labels provided are cut to match the corresponding lens
segments.
• Determine which detection zone/lens segment needs a masking label.
• Peel the desired mask label from its backing and apply to the inside of the
lens segment to be blocked.
