More info

Jablotron JA-155M is a compact wireless magnetic detector designed to detect openings of doors and windows while remaining unobtrusive in residential and commercial interiors. It succeeds the JA‑151M and incorporates updated electronics and bidirectional communication for safer transmission and remote configuration.

The detector operates on 868.1 MHz using the JABLOTRON protocol and is intended for use with control panels JA‑102K, JA‑103K, JA‑107K, JA‑152KR and newer JA‑100 series panels. Maximum RF power is <25 mW and the declared open‑area range is up to 300 m, allowing flexible placement within typical installations.

JA‑155M can be configured for state or pulse response depending on the system setup. The magnet can be mounted on either side of the contact; when mounting on metal surfaces use the supplied plastic spacers to ensure correct spacing and reliable detection.

Power is provided by one CR2032 lithium cell (3 V / 230 mAh) — battery not included. According to the manufacturer, typical battery life is 2 years; low battery is detected below 2.6 V. Quiescent current is low (≈16 µA) while maximum short‑term current can reach up to 50 mA during transmission or activation.

Detector dimensions: 28 × 58 × 17 mm; magnet: 28 × 17 × 17 mm. Detector weight without battery: 13 g; magnet weight: 16 g. The device is classified as security grade 2, environmental class II (EN 50131‑1) and complies with applicable EMC and radio standards. Installation and enrolment should be performed by a certified Jablotron technician.
