Ziton Intelligent conventional recess mount manual call point MANUAL RELEASE EXTINGUISHING SYSTEM, 0 Ω (yellow)

The Ziton NC-MCS99-0-Y is a yellow manual call point (MCP) for recess mount applications on most industry standard, high quality wall boxes. It bears the text “MANUAL RELEASE EXTINGUISHING SYSTEM”

The call point offers one normally open contact in series with a 0 Ω resistor, as well as a single pole, changeover contact with common, normally open and normally closed connections. Supplied with an EN54-style resettable element, pluggable connectors for both contacts, and a wire bridge to help with cable continuity testing as well as a test key that doubles up as a service tool for device disassembly.

Pluggable terminal blocks facilitate the pre-connection of all cables. This terminal block is connected to the MCP. Should continuity testing be needed, the handy wire bridge fits neatly into the terminal block in place of the MCP without having to disconnect any cables.

For service and maintenance no additional tools other than the test key is needed. The test key is also used to remove the front cover of the unit should a frangible element need to be replaced.

Both break glass (frangible elements) and re-settable operating elements may be used, just change from one element to another. Other than the optional frangible element, no additional parts are required.
