BUS module for magnetic contact – 2 inputs

The JA-112M is a BUS device of the JABLOTRON system. It has two wire inputs that can be connected unbalanced, single or double balanced. It is primarily used to connect magnetic contact (e.g. SA-201, SA-203, SA-211). The module has a status reaction (reports its activation and deactivation) and takes two positions in the system. It should be installed by a trained technician with a valid certificate issued by an authorized distributor.

Installation

Always connect the bus when the system is completely powered off.

When selecting the right location for the module, bear in mind that the wires leading to the detectors should not be longer than 100 m.

1. Open the module cover by pressing the cover tab (1).
2. Take out the PCB from the plastic base by pressing the tab on the left part (3).
3. Push the cables through the plastic base and attach it to the selected place with screws. For a more comfortable installation there are cut-out holes (4) in the plastic and also a cable lead with fixing clips under the module board (5).
4. Insert the PCB back and connect the cables to the terminals (9, 10).
5. If you want to use a balanced loop for better protection of a magnetic contact connection use a 1 kΩ resistor in series with the detector (see the picture 2). The balance function must be enabled in the module settings.
6. Proceed by following the control panel installation manual.
7. Close the module cover and test the module’s function.
