C-TEC NC941/SS Single Zone Call Controller c/w 12V PSU, Stainless Steel
The C-TEC NC941/SS is a high-quality single zone call controller that comes with a built-in 12V 250mA PSU. Manufactured from high-quality brushed stainless steel, this call controller is not only durable but also sleek and stylish.
Designed to work seamlessly with C-TEC's entire range of 800 Series Call System components, this controller is capable of indicating standard (constant tone) and emergency (intermittent tone) calls. It features Power On and Alarm 'CALLING' LEDs, which provide clear visual indication of call status.
The controller's onboard buzzer sounds an alarm when required, and an open collector output goes to 12V, ensuring that any connected devices are activated in case of an emergency.
Installation is a breeze, as this controller mounts on a standard UK 40mm double gang flush or surface back box. Additionally, an optional NC941B 0.3A battery backup kit is available for added peace of mind.
