JABLOTRON JA-121PW PIR+MW Motion Detector

Product Overview

This document has been machine-translated from an English original. For clarity or discrepancies, refer to the original version. If errors are found or for further questions, contact technical support (contact details at the end of this document).

The JA-121PW is part of the JABLOTRON system, used for motion detection of people in indoor building spaces. Its combination of PIR (Passive Infrared) and MW (Microwave) sensors makes it highly resistant to false alarms. It detects human movement using the PIR sensor, with confirmation from the MW sensor. An alarm is triggered when both sensors activate. The detector is designed for installation by a trained technician with a valid Jablotron certificate. This product is compatible with JA-103K and JA-107K control panels.

Installation

During installation, ensure there are no obstructions visible to the detector for the PIR sensor to function properly. It is not recommended to install the detector near metal objects, as this can affect the microwave field. It is not possible to install two or more detectors in an area where MW transmitters could interfere with each other.

Mounting Steps

1. Open the detector cover by pressing the latch (3). Do not touch the internal PIR sensor (11) as it may be damaged.
2. Release the circuit board by pressing latch (5) and remove it.
3. Break a hole in the back plastic for the bus cable.
4. Thread the cable through the hole made in the back plastic and screw the back plastic to the selected wall location (vertically, with the cover latch facing downwards).
5. Insert the circuit board into the detector's back plastic using the electronic latch (5) and connect the cable to the terminal block (8). Always connect the bus when the system power is completely disconnected.
6. Refer to the control panel installation instructions as well.

Enrollment Procedure

Basic Procedure:

1. When the detector is powered on, the yellow LED (6) will flash repeatedly, indicating the detector is not registered in the system.
2. Go to the F-Link program, select the desired bus on the Devices tab, and start the enrollment mode by clicking the "Enrol" button.
3. Press the detector's tamper contact (10) – this enrolls the detector in the system, and the yellow LED indicator will turn off.

Notes on Enrollment

• Learning can also be done by pressing the tamper contact (10).
• The detector can also be taught to the control panel by entering the serial number (9) in the F-Link program. All numbers are entered (example serial number: 1400-00-0000-0001).
• To remove the detector from the system, remove it from the appropriate locations in the control panel.
• To comply with EN 50131-1 standard, the cover latch (3) must be secured with the supplied locking screw in the prepared hole (4).

Configuration

Settings are made in the F-Link program's Devices tab. Use the "Internal settings" option for the detector (the detector's yellow LED will light up). A dialog box will appear where settings can be made (* factory settings):

Setting Detector Features

• LED Indicator: Turns off the red light (1) for optical motion indication when not set*/ turns on. Always indicates in service mode.
• PIR Resistance Level: Determines resistance to false alarms. The "Standard" level combines basic immunity and fast response. The "Enhanced" level offers higher immunity but the detector responds slower.
• MW Resistance Level: Determines the level of motion analysis performed by the MW sensor. The "Standard" level combines basic immunity and fast response. The "Enhanced" level offers higher immunity but the detector responds slower.
• MW Sensitivity: 100%, 75%*, 50%, 25%. In some installation situations, microwave detection can detect movement even behind walls, glass windows, plasterboard, etc. Therefore, perform a test using the "Test Mode - MW" option and if unwanted activations occur, gradually reduce sensitivity.
• MW Activation: "Any way armed"*, "Fully armed" / "Always" / "Never". The factory default is that PIR sensor activation confirmation by MW detection is enabled when it is both partially and fully armed. In the armed state, MW detection is disabled (so detector activation in the unarmed state occurs only from the PIR sensor). By enabling the "Fully armed" state, MW detection is active only when the bus is fully armed. When the bus is partially armed and in the unarmed state, MW detection is disabled. With the third option "Always", MW detection is always active, including in the armed state. MW detection confirmation can also be completely disabled with the "Never" option. In this case, the detector behaves like a standard PIR motion detector.
• MW Only: YES/NO*. If necessary (e.g., narrow long corridors, corridors where PIR detection is unreliable), PIR motion detection can be completely disabled. Selecting this option switches the detector entirely to MW mode.

Test Mode

The "PIR+MW" and "MW" buttons are used to test the detector in the control panel's service mode, when detector activations need to be checked with a walk test. Pressing the "PIR+MW" button calls the full detector test mode for a run test in the guarded mode. Pressing the "MW" button starts only the MW detector test mode to check sensitivity outside the guarded mode to avoid false alarms. In both cases, activation confirmation is indicated by a red signal on the detector and an activation signal is sent to the control panel - F-Link diagnostics tab. The MW detector test itself is interrupted either by pressing the "PIR+MW" button or by exiting the internal settings of the detector being tested.

Operational Test

In the control panel's service mode, the LED indicates possible motion. After exiting service mode, the detector switches to operational mode according to the selected parameters in the internal settings. Individual detector activations can also be checked in the F-Link program's Diagnostics tab.

Coverage Patterns

The PIR sensor is factory-equipped with a 110° / 12 m lens. The coverage area is as shown in Figure 1 (description of external parts) and Figure 3 (coverage patterns).

The MW detector is guaranteed to react to movements from 0 m - 12 m. In certain cases, it can detect movement behind solid obstacles (e.g., non-metallic materials like thin walls, doors, glass, running water, plastic pipes, etc.).

Due to the operating principle of the detector's MW part, MW coverage detection capabilities can vary significantly depending on the room size, shape, and furnishings where the detector is installed, especially concerning metallic materials that cause reflections or shield the generated MW signal.

Always carefully check the coverage area of the protected space during installation.

Technical Specifications

Regulatory Information and Compliance

It is recommended to familiarize yourself with the conditions set by local telecommunications authorities.

This detector must not be used in Great Britain, as the frequency 24.05-24.15 GHz in this frequency range is reserved for police speedometers. In France, there are no restrictions for fixed installations; otherwise, it is limited to 0.1 mW e.i.r.p. in the frequency range 24.10-24.15 GHz. In Russia, fixed installations are permitted up to 100 mW e.i.r.p., provided specific installation requirements are met.
