WARNING

Turn the POWER OFF at the circuit breaker before 

installing the sensor

Read and understand these instructions before installing.  This device 

is intended for installation in accordance with the National Electric 

Code and local regulations.  It is recommended that a qualified 

electrician perform

s

 this installation.  Make sure to turn off the circuit 

breaker or fuse(s) and make sure power is off before wiring the device.

Use copper wires only.

WIRING DIRECTIONS

 

As illustrated in Figure 1, The DWOS-1277 has a 180° detection range with a 

maximum distance of 40’ detection in front of the sensor

 and 20' on the sides

.  

For maximum results, the sensor must be properly installed between the height 

of 4’ to 5’ and away from obstructions such as walls, furniture and transparent 

barriers like Low-E glass.

The DWOS-1277 uses advanced passive infrared sensor to detect heat emitted 

motion. The sensor switch can turn on a load and keep it on as long as it detects 

motion. The sensor will automatically shut off the load at the end of the selected 

time delay. The countdown of the selected time delay starts after the last motion 

detected. The sensor is customizable with dials that can adjust
