DUOGUARD DP-550
Installation Instructions
GENERAL
Thank you for choosing IR-TEC dual technology
motion detector for your security system. The DP-550
is a compact motion detector that combines a passive
infrared (PIR) and a microwave (MW) motion sensor.
The alarm signal will be transmitted when both
sensors detect the motion at the same time. It
provides superior reliability in intrusion detection to
your alarm system. A unique ceiling/wall mount
bracket is provided for easy adjustment of detection
coverage.
INSTALLATION HINTS
The DP-550 may be either wall or corner mounted by
applying different knockouts. The provided mounting
bracket can be applied for ceiling or wall mount.
Corner mount is recommended for optimum detection.
Do not install where the
detector is in or facing
direct/reflected sunlight,
window onto main road to avoid
car head light.
Ensure that there are not any
obstructions (plants, screens,
furniture etc.) in the field of view
which may block the detection.
The detector should not face to
the ventilation of HVAC or any
equipment that may produce
strong temperature change.
Locate the detector at least 1
meter away from the nearest
fluorescent light to avoid
interference to MW sensor.
The tamper protection will be
activated if the locking screw of
front cover and bottom case is
loosen. Ensure to fix the screw.
