USING the C-SW INPUTS WITH BLU-IR INFRARED SENSORS
The BLU-IR Infrared Sensors can be wired to the 4-pin C-Switch euro-style
connectors. Wire each IR sensor to its’ corresponding 4-pin connector using
this pin-out:

BLU-CIF PWR RELAY & OF1 RELAY Wiring Instructions
DSP is triggered. The voltage from the +24 pin is typically connected to an
external power relay coil, which will then switch 120VAC on to the external
equipment. The PWR RELAY output is thermo-fuse protected, so it will
stop supplying power when the +24 pin exceeds 100mA. The circuit will
reset automatically once the load is disconnected.
The 4-pin OF_1 overflow relay connection is a 2-pole “dry contact” that is
normally open. These contacts will close connecting the “+” (pin 1) to the
There are two separate relay
