AD35 G2 PIR Quad Element Features
Grade 2 four-element passive infra-red intrusion detector. EXTRA Low (9 mA) current draw @12V DC operation. S.M.D. Technology. 12m, 110Convex honey comb, hemispherical infra-red lens. Walk test LED. High RFI & EMI Immunity. Pulse Counter (1, 2 and 4 pulses selectable) Temperature compensation for the sensitivity of the PIR.
Mounting Location
The AD35 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.
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 (Illustration 1).

3. Use mounting points “A”, if you are fitting the detector in a corner. Use mounting points “B”, if you are fitting the detector
on a flat surface. Use a small drill to create two fixing holes at the mounting points (Illustration 2).
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 PIR LED “ON” or “OFF” option and the sensitivity (pulse count) by setting the corresponding
jumpers on the electronic module. Note that Pulse 1 option is more sensitive than the pulse 4 option. Pulse 1 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 2 or 4 settings provides improved protection against false alarms caused by all types of environmental disturbances. (Illustration 3)

7. Position the PCB by loosening the PCB screw, and sliding the PCB up or down to the required setting (Illustration 4) . The
optimal coverage area is obtained if the PCB is on setting ‘0’ (default value).
Note : The distance range is 12m at ‘0’. An increase coverage angle will decrease the distance.
8. For disable EOL function do not set jumpers of alarm and tamper. (Illustration 6) Please Note: for Grade 2 EOL function is
required
