Bosch DS924i Installation Instructions

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.
1.0 Specifications
General
• Power supplied by 3.6 VDC Lithium Battery. Saft LS14250 (0.85 AH,
2/3AA battery).
• Typical current draw is 12 micro-amps with LED disabled.
• Typical battery life is 5 years.
• Operating temperature range of +32°F to +120°F (0°C to +49°C)
PIR Motion Sensor
• Coverage area 35 ft. (10.7 m) by 40 ft. (12 m) for Standard and Pet
Avoidance lenses.
• Optional Lens Kits available in packs of three (see Page 4).
• Internal coverage pointability +2° to -10° Vertical and ±10° Horizontal.
• Masking kit provided to block portions of coverage area.
• Field selectable sensitivity options of Standard, Intermediate, or High.
• Three minute transmitter lockout time after alarm extends battery life.
• Timed Walk Test Mode automatically disables LED after setup to extend
battery life.
• Cover activated Tamper indication. Optional wall activated Tamper is
included.
RF Transmitter
• Integral RF transmitter capable of transmitting at least 500 feet open air.
(Actual acceptable transmitter range should be verified for each
installation).
• Transmits low battery report (trouble) to the Control Panel.
• Transmits supervisory signal to the Control Panel every 64 minutes.
• Intended for use with listed compatible ITI Learn Mode control panels.
2.0 Installation Guidelines
• Keep all sensors within 100 ft. (30.4 m) of the Control Panel. The 100
foot (30.4 m) distance recommendation is given as a starting guideline.
The LM PIR Transmitter has an open air range of at least 500 ft. (152 m),
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.
