Sounder Booster Features The Advanced 4A Sounder Booster (Mxp-026) is a peripheral unit that takes a standard sounder circuit from either a control panel or other panel based sounder circuit controller and provides increased sounder output capability. This boosted output is fully monitored for open and short circuits and will take an independent supply to provide up to 4 Amps of sounder drive current to a single circuit.
