PYR-4122

Analog Hardwired Pet Immune

Passive Infrared Motion Detector

Installation Manual

1.

Introduction

The PYR-4122, an analog hardwired pet immune Passive Infrared (PIR)

Motion Detector is a high-performance, high stability intrusion sensor.

It utilizes high-temperature compensation and a unique lowtemperature compensation for maximal detection capabilities and minimal false-alarm transmissions.

The unit’s pyroelectric sensor is enclosed in a sealed chamber, protected from insects and air drafts. For higher-security still, the PYR-

4122 is supplied with a cover tamper which detects tampering with the sensor if the case is opened.

The PYR-4122 offers flexibility of operation and installation, by allowing simple selection between 1 and 3 pulses, as well as three heights using an adjustment scale.

Installation

3.1

False Alarm Reduction Effort

To reduce false alarms caused by detector installation:

 AVOID: Placing the PIR facing windows, or in direct sunlight as this heat energy can cause false alarms.

 AVOID: Wiring of the PYR-4122 in such a way that it is parallel to or sitting close to 110 VAC or 220 VAC transmission equipment or mains power line.

 AVOID: Placing near or over heat and air ducts, ovens, heat sources, radiators, and air conditioners as this may cause a false detection.

 AVOID: Placing near PL lamps, electrical ballasts, above cookers, and ovens, and above steam sources.

 AVOID: Placing the detector where the house pet can be within1.2 m (3.9 ft), like a sofa, and less than 5 m (16.4 ft) from stairs and such where the animal can climb.

 NEVER: Touch the pyroelectric sensor on the PCB as this causes permanent damage and loss of sensitivity.

PIR works according to field of view and cannot detect through walls. Avoid placing near obstructions such as large plants, curtains, behind open doors, and continuously moving objects.

Selecting the Physical Location

Select the best physical location to install the PIR, either directly to a

surface or using the BR-12 bracket (Figure 4) (sold separately).

Figure 4: BR-12

Figure 6: Mounting Knockouts and Channels

To select a location:

1.

Select a corner, flat wall, or ceiling area within a room or hallway at a height of between 1.8 m (5.9 ft.) and 2.4 m (7.8 ft.), which

best matches the criteria in Section 3.1.

2.

Ensure that the PIR or BR-12 is mounted on a non-moving, nonvibrating surface, corner, or ceiling.

3.

Wire the PYR-4122 as explained in Section 3.3.

4.

Mount the PIR (and BR-12 if used) in the desired location.

5.

After the installation, perform a Walk Test from the mounting location to ensure that the sensor pattern can detect within the coverage area (see Testing the Detector).

3.3

Wiring the PYR-4122

The PYR-4122 is wired using a terminal block, located on the front of

the PCB (Figure 5), with binding posts that are adjusted using a thin

Philips head screwdriver or a flat head screwdriver.

To wire the PYR-4122:

1.

Open the PYR-4122 casing by unscrewing the security screw

located on the bottom of the detector (Figure 6).

2.

Remove the PCB from the back case.

3.

Remove the relevant knockouts from the back case by using a

sharp tool or using a nail (see Figure 6).

4.

Open all the terminal block binding posts.

5.

Connect all the signaling cables, tamper, alarm, and so on.

6.

Wire the power supply cables.

When laying wires to the control panel, ensure that they are not parallel to high voltage mains or other radiation emitting equipment as this may cause false alarms.

7.

Leave the PCB unattached to continue with mounting the PIR (see

Sections 3.4 or 3.5).

3.4

Mounting the PIR (without using the

BR-12)

The PYR-4122 PIR is designed to be mounted onto a flat wall surface or to a corner.

To mount the PIR to a flat surface:

1.

Select the mounting location (see Section 3.2).

2.

Follow the wiring procedures in Section 3.3.

3.

Affix the PYR-4122 to the wall using screws and wall plugs (not included).

4.

Place the PCB in the casing and tighten the PCB locking screw.

5.

Set the jumpers (refer to Section 4).

6.

Close the top cover of the PIR and tighten the security screw.

3.5

Mounting the PIR using the BR-12

Attaching the PYR4122 PIR to the BR-12 bracket allows for additional deployment versatility, such as mounting the PIR to a ceiling surface and adjusting the angle of the PIR.

The BR-12 can be attached to the PIR in 3 ways and this determines which knockouts to remove and how the wiring is done.

To mount the PIR to the BR-12 bracket:

1.

Select the mounting location (see Section 3.2).

2.

Affix the BR-12 to the wall using screws and wall plugs (not included).

3.

Follow the wiring procedures in Section 3.3.

4.

Place the PCB in the casing and tighten the PCB locking screw.

5.

Attach the PYR-4122 to the BR-12 bracket.

6.

Set the jumpers (refer to Section 4).

7.

Close the top cover of the PIR and tighten the security screw.

Jumper Settings

4.1

Vertical Calibration

If the PYR-4122 is to be mounted at a height above 2.1 meters (6.89 ft) or below 1.8 meters (5.9 ft), calibrate the PCB position by moving the PCB up or down in the PIR housing accordingly before fixing it. The calibration scale on the PCB and the calibration marker on the PIR housing helps you achieve the optimum calibration setting.

The PCB calibration scale is located on the top right hand side of the

PCB (left). The calibration marker is located on the inside of the PIR housing (right).

If mounting the PIR above 2.1 m (6.89 ft.), move the PCB (+) up in the

PIR housing so that the calibration marker is parallel to a + scale. This ensures that the detection area is focused closer to the unit.

If mounting the PIR below 1.8 m (5.9 ft.) meters, move the PCB down

(-) in the PIR housing so that the calibration marker is parallel to a - scale. This ensures that the detection area is focused further from the unit, therefore maximizing detection range.

You should refrain from installing the detector higher than 2.4 m (7.87 ft.) or lower than 1.8 m (5.9 ft.) since efficiency is reduced at these heights.

5.

Testing the Detector

Following installation it is always wise to test the detector to ensure that the installation location covers the desired area and that the installation was performed properly.

5.1

Walk Test

Evaluate the performance of the detector by executing a 2-minute

Walk Test.

1.

Ensure all of the settings in the PIR are adjusted as necessary for the location according to the installation instructions above, and that the PIR case is closed and the locking screw is firm.

2.

Apply power to the unit. Allow 5 minutes for the unit to warm up and stabilize.

3.

During the Walk Test the LED flashes every time the detector detects motion. There is a five second wait period before the next detection.

4.

It is recommended that the installer test the detection by going over the protected area and seeing that the detection pattern is good.

5.

For pet immune applications, continue the test by sending the pet into the protected area.

6.

Make sure it does not trigger the detector by moving across the protected area and by climbing on furniture within that area.

7.

If necessary, adjust the sensitivity setting and the vertical calibration based on the test results and repeat the test until achieving optimal results.

4.2

Setting the Sensitivity (Pulse Counter)

To prevent false alarms caused by house pets or harsh environments, the PYR-4122 has two sensitivity modes designated, based on a programmable pulse counter.

 Medium – for normal usage and pet immune – Pulse count 3.

This setting provides improved protection against false alarms caused by all types of environmental disturbances.

 High – for harsh environments – Pulse count 1.

This setting is for high sensitivity and triggers the PIR on the first pulse. It should be used in high security installations, where the alarm must be activated on the first detected pulse.

The PIR factory setting is Medium (3 pulses).

To set the pulse counter, place the jumper on the desired pulse counter setting.
