PARADOX PMD75N Digital Wireless Motion Detector with Pet
Immunity

Introduction

The PMD75N is a wireless, digital, dual-optic passive infrared (PIR) motion detector designed for compatibility with Paradox alarm systems. It is immune to pets weighing up to 40 kg (90 lbs). The PMD75N is battery-powered and offers precision protection and high performance in maximum security applications.

Location and Mounting

At the recommended height of 2.1m (7 ft) ±10%, the PMD75N provides full coverage from 1.5m to 11m (5 ft to 35 ft). The installation height is measured from the center of the detector, refer to Figure 2.
Avoid placing the detector within proximity of the following sources of interference: reflective surfaces, direct airflow from vents, fans, windows,
sources of steam/oil vapor, infrared light sources, and objects causing temperature changes such as heaters, refrigerators, and ovens.

Avoid bending, cutting, or altering the antenna or mounting the detector near or on metal as this may affect signal transmission.
Do not touch the sensor surface as this could result in a detector malfunction.
If necessary, clean the sensor surface using a soft cloth with pure alcohol.

Installing the PMD75N

  1. Write down the serial number and the location of the PMD75N for future reference. This will be needed to enter into the Paradox BabyWare software.

  2. Using a screwdriver, pry the cover apart from the backplate, starting at the bottom.

  3. Using a Phillips screwdriver, loosen the height adjustment screw. Slide the PCB board up and gently lift the PCB out of its casing.

  4. Remove the battery compartment from the backplate.

  5. Screw the PMD75N onto the wall through the provided holes.
    Note : Ensure that the tamper screw is secured through the respective tamper hole, refer to D in Figure 1.

  6. Reinstall the battery compartment, refer to Powering the Detector before completing the following steps.

  7. Reinstall the PCB and connect the battery connector.

  8. Adjust the PCB height, refer to the PCB Height Adjustment section.
    Once adjusted, secure the height adjustment screw.

  9. Reinstall the top cover.

Powering the Detector

  1. Insert three “AAA” batteries into the battery holder while verifying polarity.
  2. Insert the battery holder into the back cover and affix the battery connector to the PCB.

After connecting the battery connector, a power-up sequence will begin (lasting 60 seconds). During this time, the red LED will flash and the detector will not detect an open zone or tamper.

Replacing Batteries

  1. Disconnect the battery connector from the PCB. Remove the battery holder and remove the old batteries.
  2. Press and release the anti-tamper switch to ensure that the unit has powered down.
  3. Follow the steps outlined in “Powering the Detector”.

PCB Height Adjustment

The PMD75N is designed for optimal performance at a height of 2.1m (7 ft) but can be installed at a lower or higher height. After you have installed the detector, ensure that the adjustable height markings on the right side of the PCB match the tab inside the back cover. For example, if the detector is installed at a height of 2.1m (7 ft), the PCB should then be adjusted to 2.1m (7 ft). Ensure to align the desired markings (height) with the back cover’s plastic tab. If another installation height is called for, readjust the
PCB accordingly. Any PCB adjustments should be followed by a walk-test of the protected area, refer to Testing the PMD75N.

Jumper Settings

Single or Dual Edge Processing (J3)
This setting determines the Digital Signal Processing (DSP) operational mode of the detector. Single Edge Processing mode should be used in normal environments with minimal sources of interference. Dual Edge Processing mode provides better false alarm rejection in the case where the detector is placed near sources of interference that can adversely affect the motion detector

Digital Shield™ Setting (J4)
In Normal Shield mode, the detector is set for normal environments. In High Shield mode, the detector is set for high-risk environments (potential interferences) and therefore provides greatly increased false alarm immunity. However, response time and detector speed may be slower.

LED Setting (J5)
This setting enables or disables the LED. The LED will illuminate for four seconds to indicate detected movement. The motion detector performs a battery test every 12 hours. If the battery voltage is too low, the LED will flash at 5-second intervals and the motion detector will send a low battery signal to the receiver. Trouble will then be generated and transmitted to the central monitoring station. The LED will flash rapidly when the motion detector transmits a signal to the receiver.

Processing Type| OFF = Dual edge
ON = Single edge
J4
Digital Shield sensitivity| OFF = High Shield (low sensitivity)
ON = Normal Shield (high sensitivity)
J5
Alarm LED (Red)| OFF = Disabled
ON = Enabled

After changing jumper settings, power cycle the PMD75N. Snap-on the cover to close the anti-tamper switch or press and release the anti-tamper switch to save the changes.

Testing the PMD75N

Open the cover to trigger the anti-tamper switch, then snap the cover back into position. This will activate the motion detector’s walk-test mode for 3 minutes.
At 20°C (68°F), in Normal Shield (J4 = ON) mode and Single Edge Processing mode (J3 = ON), you should not be able to cross more than one complete zone (consisting of 2 beams, left and right sensor detecting elements) in the coverage area with any kind of movement; slow/fast walking or running.
In High Shield mode, the amount of movement required to generate an alarm is doubled. The approximate width of a full beam at 11m (35 ft) from the detector is 1.8m (6 ft). When walk-testing, always move across the detection path and not toward the detector.
NOTE : Walk-test mode is also activated for 3 minutes once the motion detector is powered on.

Signal Strength Test

To verify the receiver’s reception of the motion detector’s signal, perform a signal strength test before finalizing the installation of the motion detector. Before performing the test, make sure the batteries have been inserted into the battery holder to power the detector. Also, verify that the motion detector has been assigned to a zone. For more information on signal strength tests and zone programming, refer to the appropriate receiver’s Reference and Installation Manual. If the transmission is weak, relocating
the transmitter by a few inches can greatly improve the reception.

Alive Software

If the motion detector transmits 2 alarm signals (LED on for 4 sec.) within five minutes, the detector falls into Energy Save mode where it won’t transmit any alarm signals for approximately 3 minutes. Due to the motion detector’s Alive Software, the red LED continues to flash to indicate a detection even when in Energy Saver mode. Once the 3-minute Energy Save mode ends, the motion detector returns to normal operation.
NOTE: If the detector’s cover is removed and then replaced while in Energy Save mode, the first detection will trigger an alarm signal.
