This is a green resettable break glass emergency door release - a single pole MCP indoor call point, which can be selected "normally open" or "normally closed" contacts.
Selecting either the “Normally Open” or “Normally Closed” contact is easily achieved by simply connecting the terminal block to the required connection in the back of the MCP3 Product. Single pole changeover switching can be achieved with the use of two terminal blocks.
It is ideal for use with security controlled locking systems, and provides a flexible solution for integrated systems which require greater functionality in the access control market.
