More details

More info

Jablotron JA-155M-GR is a miniature wireless magnetic detector designed to reliably detect door and window openings in residential and light‑industrial installations. Its small footprint and neutral grey housing enable discreet placement where aesthetics matter.

The device operates on 868.1 MHz using the Jablotron protocol and supports bidirectional communication, enabling reliable status reporting and acknowledgement with the control panel without physical access to the peripheral. RF emission is below 25 mW ERP and the nominal open‑area range reaches up to 300 m (line‑of‑sight conditions).

Technical highlights:

  • Power: 1 x CR2032 (3 V / 230 mAh) — battery not included
  • Typical battery lifetime: ≈1.5 years (manufacturer data)
  • Quiescent current: 16 µA; maximum current consumption: 50 mA
  • Frequency/protocol: 868.1 MHz, Jablotron; ERP <25 mW
  • RF range: up to 300 m in open area
  • Dimensions: detector 28 x 58 x 17 mm; magnet 28 x 17 x 17 mm
  • Operating temperature: -10 °C to +40 °C
  • Security grade: 2 / environmental class II (EN 50131-1)

JA-155M-GR is intended for standard perimeter protection and is compatible with JA‑100 series control panels (e.g. JA‑102K, JA‑103K, JA‑107K, JA‑152KR and newer). The mechanical design simplifies installation and battery replacement: attach the detector to the frame and the magnet to the moving part. Recommended fixing screws: 4x Ø3 mm (half‑rounded head).

To ensure full compatibility and correct operation use the recommended JA‑100 control panels and configuration tools. JA‑155M‑GR provides basic perimeter detection and does not replace higher grade devices where stricter requirements apply. Dispose of used batteries and the device in accordance with local regulations.
