3.2 Installing the Sensors

To install the sensor, drill a 3/8 in hole through the suspended ceiling tiles. Connect the sensor with
22 AWG shielded cable and BCN connectors. Up to 6 sensors can be connected on the active input.
Connect the shield wire on the negative terminal on the controller end only, do not connect the
shield on the sensor terminal and let it float. If many sensors are used, connect the shield between
them to ensure continuity.
Refer to the controller specifications for more details on the controller Active Control inputs and
configuration procedure.
