ATTENTION: Read carefully this installation Instructions before installing the device!
This manual is subject to change without notice!
1. General Description and Working Principle
Natron MCP is a wireless addressable manual call point designed for operation with Natron series
wireless expander modules*. In stand-by mode, the resettable (frangible) call point element is in a
middle position and the status LED is off.
* Refer to the installation manuals of Natron WE-C, Natron WE-A and Natron WE-A/C wireless expander modules for detailed
information about the programming menus and other details.
To initiate a fire alarm or evacuation event, press on the resettable element –it moves down and a color
strip is shown on at its upper side. The call point is in “Fire alarm” condition and the status LED starts
blinking fast. To reset the flexible element back in stand-by mode, use the special key tool included in
the kit - fix the long side of the tool at the call point’s bottom side and push it up until flexible element
moves up in middle position –a click is heard. Then reset the fire alarm control panel.
Attention. In case of fire alarm event and no connection between the device and the expander module
are applied the following working algorithms for conservation of the call point power battery:
- The connection between the device and the expander module is lost and after that the call
point is activated. In this case the status LED flashes 3 times and stops.
- The call point is activated, the status LED is blinking fast and after that the connection
between the device and the expander module is lost. In this case the status LED will proceed
blinking fast for 5 minutes and after that will stop if the connection with the expander module is not
restored during that period.
When the connection between the expander module and the device is restored and the call point is still
activated (the color strip is visible), the status LED will proceed blinking fast until resetting the call point.
