More info

Jablotron JA-155M-BR is a wireless mini magnetic detector designed to detect opening of doors and windows. Its small footprint and brown finish allow discreet installation on darker frames and interior fittings.

The detector communicates using the Jablotron bidirectional radio protocol at 868.1 MHz, providing reliable signalling and remote configuration via compatible JA‑100 series control panels. Enrolment and management are handled through the system control panel.

Installation is straightforward: mount the detector on the fixed frame and the magnet on the moving part (left or right mounting possible). The unit is powered by a single CR2032 lithium battery (3 V) and the battery is easily replaceable without removing the entire device.
