Installation Considerations
NOTE:
The DS860 is not recommended for installations
containing pets or small animals. Use the DS820 or
DS835 for such installations.
•
Never install the detector in an environment that causes an
alarm condition in one technology. Good installations start with
the LED OFF when there is no target motion. It should never be
left to operate with the tri-color LED in a constant or intermittent
green, yellow, or red condition.
•
Point the unit away from outside traffic (roads/alleys).
NOTE:
Microwave energy will pass through glass and most
common non-metallic construction walls.
•
Avoid installations where rotating machines (e.g. ceiling fans)
are normally in operation within the coverage pattern. Point the
unit away from glass exposed to the outdoors and objects that
may change temperature rapidly.
NOTE:
The PIR detector will react to objects rapidly changing
temperature within its field-of-view.
•
Eliminate interference from nearby outside sources.

Mounting
•
Select a location likely to intercept an intruder moving across
the coverage pattern. The surface should be solid and
vibration-free. Mounting height range is 6 to 8 ft. (1.8 to
2.4 m). Recommended mounting height is 7.5 ft. (2.3 m).
•
Remove the cover. Insert a flathead screwdriver into the locking
tab hole at the bottom front of the detector. Pull the cover up
and forward.

•
Remove the circuit board from the base. Loosen the Vertical
Adjust Screw and slide the circuit board down, then out.
•
Break away the appropriate thin-wall wire entrance and
mounting hole coverings in the base.
•
Using the base as a template and aligning it so that the
detector will be mounted with the terminal block at the top and
the PIR lens at the bottom, mark the location of the mounting
holes on the mounting surface. Pre-start the mounting screws.
