Compatible with C-TEC’s ZFP & XFP range of Apollo XP95/Discovery addressable fire panels, its 550μA quiescent current and low 5mA alarm current (sounder on max) make it one of the most efficient EN54-3 compliant wall sounders on the market. Other features include seven selectable volume levels, 15 tone pairs and a group addressing function to ensure the synchronised operation of multiple devices. Attractively finished in red polycarbonate with a deep IP33C rated base, the BF430A/CX/RR can be locked into position using the small grub screw (supplied).
