Introduction

The AD37 is a dual technology motion sensor combine range-controlled radar(RCR) technology with a passive infrared (PIR)
system to increase false alarm immunity by allowing then to sense human-sized objected with a specified range. Both the RCR
and PIR systems must be trigged to set off an alarm.
The AD37 is compact, attractive and easy to install, it can be mounted indoors on a wall or in a corner.
The AD37 is ideal for commercial, office and residential applications.
The AD37 emits no radiation and is harmless to humans & animals.
The AD37 reduces false alarms to a very low level due to its effective elimination of background noises and nuisance stimuli.

Mounting Location

The AD37 is designed for indoor use. It should not be mounted near to large
metal objects or on metal surfaces. It needs to be mounted on a wall or in a
corner at a height of approximately 2-2.5meters for the best general
coverage in an average room. The detector has been designed to avoid false
alarms, nevertheless, it is best to avoid looking directly at sources of heat
such as fires and boilers, and always try to keep away from a window. A
PIR can look at a radiator but should not be sited above one.
Please note that the microwave sensor can penetrate walls, floors and
ceilings.

When installing multiple sensors:

-DO NOT mount sensors facing each other.

-DO NOT mount facing moving or vibrating objects. (fans, pulleys, conveyor belts)

-Mount them at least 40 feet(12.2m)apart.

-Mounting sensors back to back is not recommended, but if an application requires such mounting, use the 13 ft (4.0m)range,
mount at least 1 ft(0.3m) apart, and walk test the installation to ensure proper operation.
Do not site a PIR where its field of view may be obstructed (e.g. by curtains). Also note that PIRs work best when sensing
movement across rather than along their detection beams. You need to consider the need to wire these units back to the Control
Unit.

Mounting the detector

1. Remove and retain the screw from the bottom of the PIR and lift off the cover.

2.

Carefully remove the electronic module from its retaining clips, ensuring not to touch the pyroelectric sensor and RCR
Sensor (Illustration 1).

3. Install PIR on wall as below figure

4. Hold the base of the PIR in the chosen position, ensuring that the front of the PIR will face

towards the center of the protected area, mark and drill two fixing holes in the wall.
Choose one of the cable entry holes “C” and make a third hole in the detector base. Put one end of the wire through this
hole “C”, then secure the PIR to the wall.

5. Replace the electronic module into the retaining clips, ensuring that it is correctly positioned and firmly seated.

6. If required, select the LED “ON” or “OFF” option and the sensitivity (pulse count)of PIR by setting the corresponding

jumpers on the electronic module. Note that Pulse2 option is more sensitive than the pulse 4 option. Pulse 2 option is used
when it is necessary to activate an alarm on the first detected pulse, or in high security installations – where fast “catch”
performance is of greatest importance. Pulse 3 or 4 settings provides improved protection against false alarms caused by all
types of environmental disturbances. (Illustration 3)

7. Jumper J14 for walk test of part company. Selected 1-2 position for PIR testing, Selected 2-3 position for range-controlled

radar(RCR), Selected 3-4 position for PIR and range-controlled radar(RCR) testing together. (Illustration 3)

8. Range-controlled radar (RCR) provides trimmer (VR2) to select the detection range. (Illustration 4). You need to set VR2

as close to the intended coverage range as possible. Overshooting the coverage area may cause false alarms.

9. For disable EOL function do not set jumpers of alarm and tamper. (Illustration 6)

10. Enable EOL function and selectable EOL resistance.

Refer to the chart below for the correct end of line resistance, and set jumpers of

alarm and tamper. (

Illustration 5、Illustration 7 and Illustration 8) Please Note: for Grade 2 EOL function is required
