JA-121PW Bus Combined PIR+MW Motion Detector

Product Overview

The JA-121PW is a component of the JABLOTRON system, designed for spatial detection of movement of people within interior spaces. Its combination of Passive Infrared (PIR) and Microwave (MW) sensors significantly enhances resistance to false alarms. The detector triggers an alarm only when both sensors are activated. It is intended for installation by trained technicians holding a valid Jablotron certificate and is compatible with JA-103K and JA-107K control panels.

Installation

When installing, ensure there are no obstacles in the detector's view for optimal PIR sensor function. Avoid installing the detector near metal objects, as this can interfere with the microwave field. It is not advisable to install multiple detectors in an area where their MW transmitters could interfere with each other.

• 2: PIR sensor lens
• 3: Cover latch
• 4: Hole for locking screw

Installation Steps

1. Open the detector cover by pressing the latch (3). Avoid touching the PIR sensor (11) inside, as it may be damaged.
2. Release the Printed Circuit Board (PCB) by pressing the latch (5) and remove it.
3. Break a hole in the rear plastic for the bus cable.
4. Thread the bus cable through the prepared hole in the rear plastic.
5. Mount the rear plastic to the selected wall location vertically, with the cover latch facing down.
6. Insert the PCB back into the rear plastic using the electronics latch (5) and connect the cable to the terminal block (8). Important: Always connect the bus when the system power is completely off.
7. Refer to the control panel's installation manual for further details.

Basic Enrolment Procedure

• When the detector is powered on, the yellow LED (6) will flash repeatedly, indicating it has not been enrolled into the system.
• Using the F-Link program, select the detector's position in the Devices tab and initiate the enrolment mode by clicking the "Enrol" button.
• Press the tamper contact (10) on the detector. The detector will then be enrolled, and the yellow LED indicator will turn off.

Final Steps and Notes

• Close the detector cover and secure it with the locking screw (4).
• Learning can also be initiated by pressing the tamper contact (10).
• The detector can be learned into the control panel by entering its serial number (9) into the F-Link program (e.g., 1400-00-0000-0001).
• To remove a detector from the system, delete its entry from the control panel configuration.
• To comply with EN 50131-1, the cover latch (3) must be secured with the supplied locking screw into the prepared hole (4).

Setting Detector Properties

Detector settings are managed via the F-Link program in the Devices tab. Access the "Internal Settings" option at the detector's position (indicated by the yellow LED lighting up) to open a dialogue for configuration. Factory settings are marked with an asterisk (*).

• LED indication: The red light (1) serves as a motion optical indicator when the system is unset. It always indicates in service mode.
• PIR immunity level: This setting determines resistance to false alarms.
  • Standard*: Combines basic immunity with a fast response.
  • Enhanced: Provides higher immunity but results in a slower detector response.
• MW immunity level: This setting adjusts the motion analysis performed by the MW sensor.
  • Standard*: Combines basic immunity with a fast response.
  • Increased: Provides higher immunity but results in a slower detector response.
• MW sensitivity: Options include 100%, 75%*, 50%, 25%. In certain installations, microwave detection might pick up movement through walls or glass. Use the "Test Mode - MW" option for walk tests and gradually reduce sensitivity if unwanted activations occur.
• MW activation: Options are Any way secured*, Fully secured, Always, Never.
  • The default setting enables MW confirmation of PIR activation for both partially and fully armed states. In the set state, MW detection is disabled (activation only from PIR).
  • Fully armed: MW detection is functional only when the section is fully armed. When partially armed or unset, MW detection is disabled.
  • Always: MW detection is always active, even when the system is armed.
  • Never: MW detection confirmation is completely disabled, making the detector function solely as a standard PIR motion detector.
• MW only: Set to YES/NO*. If PIR detection is unreliable in certain environments (e.g., narrow corridors), this option can disable PIR detection, making the detector operate in full MW mode.
• Testing mode: PIR+MW and MW buttons are used for walk tests in the control panel's service mode.
  • Pressing the PIR+MW button or closing the front cover initiates a full detector test for the guarded room.
  • Pressing the MW button initiates a test for MW detection only, useful for checking sensitivity outside the guarded area to prevent false alarms.
  In both test modes, activation is indicated by a red detector signal and an activation signal sent to the F-Link diagnostics tab. The MW detection test is interrupted by pressing the PIR+MW button again or by exiting the service mode. The testing mode is limited to 15 minutes.

Function Test

In the control panel's service mode, the LED indicates any detected movement. Upon exiting service mode, the detector operates according to the selected internal settings. Individual detector activations can be monitored in the F-Link program's Diagnostics tab.

The PIR sensor is factory equipped with a 110° / 12 m lens. Coverage characteristics are illustrated in the diagrams.

Coverage Characteristics (Figure 3)

PIR Coverage: The PIR sensor has a detection angle of 110° and a range of 12 meters.

MW Coverage: The MW sensor is designed to react to movement from 0 meters up to 12 meters. In specific situations, it can detect motion through non-metallic materials such as thin walls, glass windows, or plasterboard, and even through running water in plastic pipes.

Diagram Description: The diagrams visually represent the detection areas. The PIR coverage shows a wide, fan-like pattern extending outwards from the detector. The MW coverage shows a similar pattern but is generally narrower and extends closer to the detector, with a note indicating detection is possible from 0m.
