C-TEC NC943B Single Zone Call Controller c/w 12V 140mA PSU, call accept
The C-TEC NC943B is a compact and attractive single-zone call controller. With its 12V 140mA PSU and standby battery, this call controller is compatible with C-TEC’s entire range of 800 Series Call System components, making it easy to integrate into your existing system.
Designed to indicate standard (constant tone) and emergency (intermittent tone) calls, the NC943B features a volume adjustable sounder and a link-selectable Call Accept/Reset button, giving you complete control over your call system. The Power On and Alarm ‘CALLING’ LEDs provide clear visual indication of system status, while the volt-free relay output allows for the optional connection of externally powered beacons and other devices (relay activates on active call signal).
With a standby battery that provides up to 24 hours standby and 15 minutes alarm running time, the NC943B is a reliable and effective call controller that you can depend on. It mounts on a standard UK 25mm double gang flush or surface back box, and is also available as part of the NC951 Accessible Toilet Alarm Kit.
