Product Description
The NC944 is an attractively-designed four zone call controller c/w mute and reset buttons. It is fully compatible with the C-TEC entire range of 800 Series Call System components.
It is capable of indicating standard (constant tone) and emergency (intermittent tone) calls.
It requires a separate NC930 12V 250mA PSU. But includes four zonal alarm LEDs, RESET and MUTE buttons. There is also two open collector outputs (Emergency and Aux Out). Which means up to two NC944s can be connected to one NC930 PSU to create a mini-call system of up to 8 zones.
