JABLOTRON JA-121PW Bus PIR+MW Motion Detector

Introduction

This document is a translation from the original English. For any uncertainties, please refer to the original. Contact technical support for errors or questions.

The JA-121PW is a JABLOTRON system component for detecting human movement indoors. Its dual PIR+MW technology provides high resistance to false alarms, requiring both sensors to trigger an alarm. Installation must be performed by a certified professional. Compatible with JA-103K and JA-107K control panels.

Installation

General Guidelines

During installation, ensure clear PIR view and avoid installing the detector near metal objects to prevent microwave field interference. It is not possible to install two or more detectors in the same area, as MW transmitters can interfere with each other.

Mounting Procedure

Figure 1: External Parts Description

• 1 - Light guide
• 2 - PIR detector lens
• 3 - Cover latch
• 4 - Hole for securing screw

1. Open the detector cover by pressing the latch (3). Do not touch the PIR detector (11) inside, as it may be damaged.
2. Release the printed circuit board (PCB) by pressing latch (5) and remove it.
3. Drill a hole in the back plastic for the bus cable.
4. Thread the cable through the prepared hole in the back plastic and screw the back plastic to the wall at the chosen location (vertically, with the cover latch facing down).
5. Insert the PCB into the back plastic of the detector using latch (5) and connect the cable to the terminal block (8).

Note: Connect the bus only when the system is completely powered off.

Device Registration

Refer to the control panel installation manual for basic procedures.

1. Upon powering up the detector, the yellow LED (6) will flash repeatedly, indicating it has not yet been registered in the system.
2. Enter the F-Link program, select the desired position in the Devices tab, and start the enrollment mode by clicking the Enroll button.
3. Press the tamper contact (10) inside the detector. The detector is now enrolled, and the yellow LED indicator will turn off.

Final Steps

1. Close the detector cover and secure it with the locking screw (4).

Notes

• Enrollment can also be performed 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. All digits must be entered (e.g., serial number: 1400-00-0000-0001).
• To remove the detector from the system, delete it from the corresponding positions in the control panel.
• For compliance with EN 50131-1, the cover latch (3) must be secured with the provided locking screw in the prepared hole (4).

Features and Settings

Configuration via F-Link

Settings are made in the F-Link program on the Devices tab. For the detector's position, use the 'Internal settings' option (the yellow LED on the detector will light up). A dialog box will appear where settings can be configured (* denotes factory default):

• LED Indication: Turns off*/on the red light (1) for optical motion indication when not armed. It always indicates in service mode.
• PIR Immunity Level: Determines resistance to false alarms. The Standard* level combines basic immunity with fast response. The Enhanced level provides higher immunity but slower response.
• MW Immunity Level: Determines the level of motion analysis performed by the MW detector. Standard* combines basic immunity with fast response. The Enhanced level provides higher immunity but slower response.
• MW Sensitivity: Options are 100%, 75%*, 50%, 25%. In certain installation scenarios, MW detection can sense motion behind walls, glass, plasterboard, etc. Therefore, perform a test using the 'Test Mode - MW' option and gradually reduce sensitivity if unwanted activations occur.
• MW Activation: Options include Any Arm*, Fully Armed, Always, Never. The factory default allows MW confirmation of PIR activation when the system is partially or fully armed. When armed, MW is disabled (activation only by PIR). The 'Fully Armed' option means MW detection only works when the zone is fully armed. If the zone is partially armed and not armed, MW detection is off. The 'Always' option means MW detection is always active, even when armed. MW confirmation can be completely disabled using the 'Never' option, in which case the detector behaves like a standard PIR motion detector.
• MW-Only Mode: YES/NO*. If necessary (e.g., in narrow, long corridors where PIR detection may be unreliable), PIR motion detection can be completely disabled. Selecting this option switches the detector to full MW operating mode.

Test Mode

The PIR+MW and MW buttons are used for testing the detector within the control panel's service mode, allowing verification of detector activation via a walk test. Pressing the PIR+MW button or closing the front cover activates the full test mode for the protected area, enabling error checking. Pressing the MW button initiates the MW detector's test mode for sensitivity checks outside the protected area, helping to prevent false alarms. In both modes, activation is confirmed by a red detector indication and a signal sent to the control panel (F-Link Diagnostics tab). The MW detector test can be interrupted by pressing the PIR+MW button or exiting the tested detector's internal settings. The MW detector test can be terminated by pressing the PIR+MW button or leaving the tested detector's service mode. The test mode duration is limited to 15 minutes.

Detection Coverage

PIR Coverage

The PIR detector is factory-equipped with a 110° / 12 m lens. The coverage area is depicted in the diagram below, characterized by a white pattern.

Figure 3: Coverage Characteristics Diagram

The diagram illustrates the coverage pattern of the detector. The PIR sensor provides a wide-angle detection area, approximately 110 degrees horizontally and up to 12 meters in range. The MW sensor complements this with its own detection pattern, also up to 12 meters.

MW Detection

The MW detector reliably detects motion from 0 m to 12 m. In certain cases, it can detect motion behind fixed obstacles such as non-metallic materials (e.g., thin walls, doors, glass, flowing water) or within plastic pipes. The MW detection characteristics can vary significantly depending on the room's size, shape, and equipment, particularly due to metallic objects that reflect or shield the generated MW signal.

Always carefully verify the coverage of the protected area during installation.

Technical Specifications

We recommend familiarizing yourself with conditions set by local telecommunications authorities.

Regional Restrictions: This detector must not be used in Great Britain as the 24.05-24.15 GHz frequency is allocated to police speed measurement devices. France has no restrictions for fixed installations, otherwise limited to 0.1 mW e.i.r.p. in the 24.10-24.15 GHz. Russia allows fixed equipment up to 100 mW e.i.r.p., adhering to specific installation requirements.
