The NC-MCS99-0-R is a vibrant red manual call point designed for recess mount applications on most industry-standard, high-quality wall boxes. For surface mount applications, you can use an optional, color-matched back box.
This call point features one normally open contact in series with a 0 Ω resistor, along with a single pole, changeover contact with common, normally open, and normally closed connections. It comes with an EN54-style resettable element, pluggable connectors for both contacts, a convenient wire bridge for cable continuity testing, and a test key that also serves as a service tool for disassembling the device.
