Description
The Johnson Controls M501MJ is an addressable mini monitor module for Johnson Controls intelligent fire alarm control panels, from the earlier M500 series.
Please note the product category. This is fire alarm equipment, not HVAC or building automation.
What the mini format is for. A mini monitor module is small and light enough to install in a single-gang junction box directly behind the device it monitors, without rigid mounting - where a standard monitor module needs a 4 in. square box. On a retrofit into an existing building, that difference is often what makes the installation possible at all.
What a monitor module does. Monitor modules supervise a circuit of dry-contact input devices - conventional heat detectors, pull stations and similar - and report the circuit status back to the panel over the signalling line circuit. Each module occupies one module address on the loop.
Please confirm the detailed specification with us before ordering. Johnson Controls' current datasheet for this family covers the M300-series modules, including the M301MJ mini monitor module. The earlier M501MJ is documented separately and we have not been able to source its specification sheet, so we have not stated its voltage range, current draw or circuit limits.
Original or current generation? Johnson Controls states that the M300MJ replaces the M500MJ in existing systems, and the M301MJ is the current-generation mini monitor module. We stock both generations. An original is often the better choice when you are matching a panel already populated with M500-series modules - it avoids any question over panel programming, documentation and inspection records.
