The C-TEC BF431A/CX/W is a 96dB addressable base sounder which is compatible with Apollo’s range of XP95 and Discovery detection devices and designed for use on C-TEC’s XFP and ZFP fire panels.

The Base Mount range of addressable, loop-powered bases includes sounders, visual alarm devices (VADs) and combined sounder VADs. They are designed for use with C-TEC’s ZFP/XFP panels and other Apollo Discovery compatible fire panels.

Their purpose is to visually and audibly alert building occupants of a fire alarm.

All bases can be optionally used as either:

a stand-alone base using a separately available locking white cap (BF330CTLIDW) / red cap (BF330CTLIDR), or
a combined, base and Apollo detector (Apollo detectors are separately available).
The bases offer low current consumption, high sound output, high efficiency VADs, seven selectable volume levels, 15 selectable tone pairs and built-in short-circuit loop isolators. The combined sounder and VAD on the BF432A/CX/W and BF456A/CX/W bases can be set to operate independently of each other (panel dependent function).

All bases (excluding BF432A/CX/W and BF459A/CX/W) are fully certified with all relevant sections of the fire alarm device standards EN 54-3 (Sounders), EN 54-23 (Visual alarm devices – VADs) and EN 54-17 (Short-circuit isolators).
