20 Zone Master Call Controller, flush, c/w 12V 300mA PSU, relay, reset & mute/call buttons

The NC920F is compatible with C-TEC’s entire range of 800 Series field devices.

Housed in flush mounting plastic enclosure the NC920F measures at just 214mm x 178mm. It has two call levels – standard which is a constant tone and emergency an intermittent tone. It also has an optional mute and call accept/reset buttons.

The ‘Call Accept’ functionality allows staff to send an intermittent call acknowledgment signal to calling zones to confirm help is on the way (dependent on wiring and field devices used).

It includes a 12V 300mA PSU and 2 volt-free relay contacts which activate on a standard or emergency call. As well as innovative slide-in labelling system.

Zones can be wired in 4 or 6 core (7/02) stranded security cable. Additional master controllers and expansion units are available for use as repeaters on larger sites.
