The Honeywell 585031 AMP 4XD250B is a four-channel class D power amplifier with a built-in battery charger for the VARIODYN ONE voice alarm system. Each of its 4 independent channels delivers 250 W with direct-drive technology. Because the channels are fully independent, one can be used as a backup channel.
