More info

JA-151M is a mini wireless magnetic detector designed to detect openings of windows and doors. Its slim, discreet housing makes it suitable where a small footprint is required while maintaining professional alarm system performance.

The device is addressable and occupies one position in the alarm system. It includes a tamper switch (protection against removal) and an activation LED. The set consists of a transmitter unit and a permanent magnet; the magnet can be mounted in alternative positions to suit different frame types.

Power is supplied by a single CR2032 lithium battery (3.0 V/0.2 Ah) — battery not included. Typical battery lifetime is approximately 2 years with up to 20 activations per day; actual life depends on usage and environmental conditions.

Radio communication uses 868.1 MHz (JABLOTRON protocol) with maximum RF power ERP 3 mW and an approximate communication range of 200 m in open area. The detector is intended for indoor use (environment class II per EN 50131-1) and operates from -10 °C to +40 °C. It is rated as grade 2 according to EN 50131 standards.
