Flex7 FNC 2000 Control Pack Occupancy Sensing is a control device which plugs directly into the eZeBox range of connection units or a 7 pole single socket outlet. Working with at least a plug-in sensor head and/or a switch, the device will control the connected mains rated luminaires ON and OFF. The exact operation will largely depend on which of the input devices are connected. It can be linked together using simple plug-in network leads. This provides a simple way of sharing inputs and outputs between controls. Each Control Pack is also available with an additional relay to facilitate emergency test. Simply connect one of the cores of the switch drop to a suitable key switch.
