The Advanced MXS-025 is a sounder booster card for MxPro 4 control panels, supplied as the PCB only. It is triggered by a standard sounder circuit (panel or loop driven) and gives a single, fully monitored boosted sounder output, taking an independent supply to deliver up to 4A of sounder current.
The card must sit at the end of the panel's sounder output circuit to keep correct fault monitoring. Advanced states that it needs a power supply of at least 4A and an enclosure. On-board LEDs show when the output has been triggered and when an external supply is connected.
