New product

JABLOTRON ALARMS S.A.

JA-122PW (G) is a JABLOTRON 100+ bus dual PIR & MW motion detector combining PIR and microwave sensing for reliable coverage up to 12 m. The grey lens improves white‑light immunity to 10000 lux; PIR and MW sensitivity are adjustable separately.

More details

More info

The JA-122PW (G) is a bus-mounted dual motion detector for the JABLOTRON 100+ system. It combines passive infrared (PIR) and microwave (MW) technologies to detect human movement indoors while reducing false alarms.

In normal operation the PIR sensor functions as the primary detector; when PIR registers motion the MW sensor is enabled to confirm the event before reporting to the control panel. This confirmation logic increases resistance to interference and false triggers. The unit uses a pulse response and occupies a single bus position.

The grey (G) lens significantly increases immunity to strong white light (up to 10000 lux), helping to prevent false alarms caused by reflections, car headlight refraction, low‑angle sun or lightning.

Designed for indoor mounting with a recommended installation height of 2.5 m, the detector is powered from the control panel bus at 12 V DC (9…15 V). Alarm immunity levels can be adjusted independently for PIR and MW to suit the protected environment.

Key specifications

  • Detection: PIR 90° / 12 m, MW 80° / 12 m
  • MW frequency: 24.125 GHz, ERP 30 mW
  • Power: bus 12 V DC (9…15 V); quiescent current 5 mA, max 16 mA
  • Size / weight: 150 × 63 × 40 mm; 120 g
  • Operating conditions: -10 °C to +40 °C, 75 % RH without condensation
  • Classification: security grade 2 / environmental class II (EN 50131-1)
  • Mounting: indoor, recommended height 2.5 m

Correct placement and configuration (sensitivity settings, orientation, mounting height) are essential to achieve reliable detection and minimise false alarms. JA-122PW (G) is compatible with the JABLOTRON 100+ system and should be installed following the manufacturer's guidelines.
