BUS module for magnetic detectors JA-112M

JA-112M — BUS module for magnetic contacts (2 inputs)

The JA-112M is an addressable BUS device for the JABLOTRON 100+ alarm system, intended for connecting wired magnetic switches used to detect door and window openings. The module reports the status of its inputs and occupies two positions in the system.

Both inputs are fully configurable: they can be connected unbalanced, single-balanced, double-balanced or set to a roller blind function. Input inversion and minimum activation time are adjustable (from 0.1 s up to 300 s), allowing fine tuning for different contact types and installation conditions.

Each input supports up to 100 m of wiring to the magnetic contact. The module is powered from the control panel BUS (12 V, range 9…15 V) and should be installed according to the manufacturer’s instructions by a trained technician or authorized installer.

Key specifications
