The C-TEC BF458A/CX/SW is a compact addressable loop-powered wall VAD in white. It provides W-3-3.1 light distribution when wall mounted (min 0.4 lux over a 3 x 8m cylindrical area) or it can also provide C-3-8 light distribution when ceiling mounted (min 0.4 lux over a 2.4 x 3.5m cuboid area). It is compatible with XP95/Discovery protocol systems and designed for use with C-TEC's XFP and ZFP fire panels.
 
The Compact range of addressable, loop powered, devices include sounders, visual alarm devices (VADs) and combined sounder VADs. They are designed for indoor use with C-TEC’s ZFP/XFP and other Apollo Discovery compatible fire panels.
 
Their purpose is to visually and audibly alert building occupants of a fire alarm. The devices 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 sounder and VAD on the combined device can be set to operate independently of each other (panel dependent function). 
 
All devices are fully compliant with the 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).
