PIR + Microwave Motion Detector
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 once release the
locking screw of front cover and
bottom case.

Avoid running the alarm cable along with AC mains
cables !!!

With mounting bracket
1. Mount the base of mounting bracket on the
selected position. Lead the cable through the
cable access tunnel of mounting bracket.
2. Open the front cover and carefully remove the
PCB from the bottom case. Lead the cable into
the case and assemble the mounting bracket with
it (as shown on previous page).
3. Connect the cable to the corresponding terminals
according to the following instructions. Replace
the PCB on the bottom case and fix it. Replace
the front cover and then walk test can be
conducted.
Without mounting bracket
1. Open the front cover and carefully remove the
PCB from the bottom case. Select the adequate
knockouts and mount the case on the position.
2. Connect the cable to the corresponding terminals
according to the following instructions. Replace
the PCB on the bottom case and fix it. Replace
the front cover and then walk test can be
conducted.

WALK TEST
It is necessary to carry out a thorough walk test of the
detector to ensure that the correct coverage is being
achieved. Also to ensure that both PIR & microwave
are sensors working to the same detection area.
1. Apply the DC power supply and give
approximately 60 seconds for sensor to warm up.
After the warm up time expires, walk across the
detection zones at normal speed. The red LED
will lit when it detects the motion.
2. If microwave sensor is too sensitive (green LED
remains on), then carefully adjust of the thumb
wheel of MW sensitivity controller in
counterclockwise until the detection is
satisfactory.
DIP SWITCH FUNCTIONS
There is a 5-pole dip switch on the PCB which controls
various functions.
