PIR MOTION DETECTOR INTRODUCTION The PIR-3SP Passive Infrared Detector detects the movement of human body heat within its effective coverage; thus, when an intruder crosses or enters the area, the resulting change in infrared energy from the intruder will be detected and an alarm signal will transmit to the Base Unit. PET IMMUNE DETECTOR  This detector is immune to one domestic pet up to 18 kg or 60 cm moving on the floor.  If animal activity takes place above 1 meter high, the pet immunity allowance will be significantly reduced. Therefore Do Not aim the detector at stairways that animal can pass.  This detector should be mounted on the wall or corner at 2.0 m high and perpendicular to the floor. Please note under this condition, the human motion within 1 m from the detector is undetectable.  Do NOT use any mounting bracket with swivel adjustment. Should you must use a bracket, it should be used for horizontal alignment only, do not tilt down.  Place the PCB at the “0” scale position. (for PCB version ST-IR-3B, or “P” scale for ST-IR-3A). And jumper JP5 at “PET” position.  It’s a must to verify the pet immune function after installation. In case animal is detected, sliding the PCB to +1~+2 scale to test again (for PCB version ST-IR-3B, or to -1~0 scale for ST-IR-3A).  The weight of the animal can only be used as a reference. Other factors such as height and color of fur could also affect the level of immunity. IMPORTANT NOTE To get the best sensitivity, PIR should be mounted to detect movement of the intruder across a room rather than toward the detector.

Do not install where the detector faces a window, since movement outside could cause unwanted alarms. Make sure the detection area does not have obstructions (curtains, screens, large pieces of furniture, plants, etc.) that could block the pattern of coverage. Avoid placing the sensor in areas containing objects likely to produce a rapid change in temperature, such as central heating radiators or ducts (or heaters of any kind), air conditioners, open flame, etc. INSTALLATION 1. Refer to FIG. 2, and loosen the screw on the PIR bottom, and then remove the front cover. 2. Insert two AAA alkaline batteries. Select “Installer Mode” on the Base Unit and enter the Installer Code to gain access authority. Then select \Set Device\Enroll Device\Burglar Sensor\Enter Zone No. to enroll the ID of PIR-3SP by pressing its TEST button on the PIR board. You may change its various attributes under \Set Device\Change Device Setting\Burglar Sensor Change, to fulfill different requirements. Important Notice: In order to reset the microprocessor properly, before replacing the batteries in the PIR-3SP, press the TEST button for 5 seconds to discharge the energy that remains in the capacitor on the PC board. Otherwise, it may not restart. 3. After power on, wait one minute for sensor warm-up. 4. Mount the base with two screws (refer to Fig. 4) or use Velcro tab provided at a selected location, and 2 m above the floor. Make sure the distance between PIR and Base Unit is within RF transmission range. $ Fig. 2 Screw Holes Fig. 3  Open Test Button Simulation ON OFF Fig. 4 Fig. 5 2
WALK TEST It is essential to perform a walk test to verify optimum detection coverage. To do this, first hold the “TEST” button on the PIR-3SP board down for at least 3 seconds, until the LED turns ON→OFF→ON, then release the button. Afterward, the PIR-3SP enters “TEST” mode for 3 minutes. Replace the cover of the PIR-3SP, then walk into the detection area at normal speed, while observing the LED indicator. The LED stays ON normally, and turns OFF when motion is detected. If the detection pattern is not satisfactory, re-aiming the detector or adjusting the vertical pattern by sliding the PIR board to -1 or 0 scale to test again. Notes: 1. For the sake of convenience, the PIR is built in a reed switch; refer to its location on Fig. 1. You may use a magnet to simulate the function of TEST button without opening the case. When a magnet is placed close to the reed switch, the PIR responses as the TEST button is pressed; refer to Fig. 5. And when a magnet is removed, the PIR responses as the TEST button is released. 2. Test mode can be terminated before the 3-minute timeout by pressing the “TEST” button again (or use a magnet to approach for a second) until the LED turns OFF. Afterward, it returns to NORMAL mode. 3. In NORMAL mode, the PIR-3SP activates the transmitter when it initially detects movement, then disables itself. The unit will resume operation only after about 3 minutes with no further detection of movement. In other words, if installed in a heavy traffic area, the PIR-3SP will not transmit until the area has been evacuated for 3 minutes. The purpose of this feature is to reduce power consumption and prolong battery life. RADIO LINK TEST Open the top cover of the PIR-3SP and press the TEST button on the PC Board, or use a magnet to activate the reed switch, to see whether the Base Unit can receive the radio signal. PULSE COUNT SELECTION The PIR-3SP is equipped with a programmable pulse counter that can be set by placing the jumper on the desired setting (2 or 4). The PIR-3SP automatically overrides to one-pulse mode while in "TEST" mode. 2 pulses: This setting has high sensitivity of detection. Two pulses should be selected when the detection range is longer (over 5 m) 4 pulses: Alarm signal will only be sent if 4 pulses are detected within approximately 1 minute. This setting provides the maximum protection against false alarms caused by all types of environmental disturbances. LED ON/OFF SELECTION To prevent the PIR from being discovered by an intruder, LED can be disabled by putting LED ON/OFF jumper at OFF position. Nevertheless, the LED is enabled automatically when the PIR-3SP is in “TEST” mode, even with the jumper at the OFF position. 3

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio communication. However, there is no grantee that interference will not occur in a particular installation. If this equipment dose cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: --Reorient or relocate the receiving antenna. --Increase the separation between the equipment and receiver. --Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. --Consult the dealer or an experienced radio/TV technician for help. 110°Top ViewSide View2m 0.6m 1m 8m 12m
APPENDIX The PIR-3SP can be used as a conventional detector (non pet-immune) if changing lens to LN-N type (refer to Fig 6). And the model no. becomes PIR-3S. Note: 1. When you use LN-N lens, you must place JP5 at “NORL” position. 2. The detection patter of PIR-3S is as below (max. distance 15m), and you may adjust PCB scale position to fit detection coverage, or use bracket IRB-3 to adjust detection coverage. Besides, you may change the installation height properly. DETECTION PATTERN (PIR-3S) Fig. 6 110°Top ViewSide View2.3m1m 2.5m 8m 15m4
