DS940Q
Passive Infrared Detector
Installation Instructions
1.0 Description
The DS940Q is a high performance Passive Infrared (PIR) Motion Detector which uses advanced signal processing to provide outstanding
catch performance and unsurpassed false alarm immunity. It is designed to detect movement in the interior of a structure by sensing the
Infrared energy emitted from the human body as it moves across the detector’s field of view. When motion is detected, the detector sends an
alarm signal to the Control Panel.

This detector contains an environmental
stabilization circuit which requires
approximately 2 minutes after initial
power-up to warm up. During this time
the detector will not respond to any
movement.
Please wait 2 minutes after initial power-up to
perform any walk tests.
Although generally not required, if
masking is desired, the lens diagram
shows the appropriate areas to be
masked (see shaded area on the
DS940Q lens diagram). Use an
opaque material (such as, electrical
tape) to mask the desired areas. DS940Q Lens
