The Intrinsically Safe Manual Call Point (MCP3A) is a manually-operated fire alarm switch for use in areas subject to explosive atmosphere.

The MCP3A has a flexible plastic activating panel. When pressed, this flexible element slides downward, activating an internal switch which triggers the alarm signal. The flexible element remains in the activated position until it is physically reset.

The MCP3A manual call point is supplied with a test key (SC070). When inserted into the call point, the test key triggers an alarm condition without moving the flexible element. The MCP3A returns to normal when the test key is removed.

The test key is also used to remove the lower part of the front panel to reset the flexible element, to access the mounting screws, or to change the flexible element.

To comply with the requirements of NZS 4512:2010, this manual call point must be fitted with a PS200 protective hinged cover (sold separately).

The manual call point is supplied with a back-box for surface mounting. It may also be used in flush-mount applications.
