Advanced MXP-541A-002 AlarmCalm button w buzzer (Apollo)

The Advanced MXP-541A-002 is an AlarmCalm button for the Apollo protocol, with a programmable buzzer. It is an intelligent, loop-powered module that connects to an Apollo detection loop on an MxPro 5 multi-protocol fire panel, as part of Advanced's AlarmCalm false alarm management (FAM) solution.

Fitted inside a dwelling or apartment, it lets occupants acknowledge a local alarm: pressing the button during the stage-1 period silences locally programmed sounders and extends the verification time (stage 2) before the panel enters a full fire condition. It is configured with the AlarmCalm software.
