Installation Instructions

for the DS835i/DS835iT Series TriTech Microwave/PIR Intrusion Detectors with Pet Immunity

1.0 Description

The DS835i and DS835iT Series are high performance TriTech passive infrared (PIR)/microwave (MW) motion detectors that use advanced signal processing to provide outstanding catch performance and unsurpassed false alarm immunity. They are designed to detect movement of a human body in the interior of a structure as it moves across the detector's field of view. When motion is detected, the DS835i and DS835iT send an alarm signal to the control panel. With the Pet Friendly This pet immunity feature has not been tested by Underwriters Laboratories, Inc. (UL).

This detector contains an environmental stabilization circuit. After the initial powerup, the detector needs approximately 2 min. to warm up. During this time, the detector does not respond to any movement.

Note: Wait 2 minutes after the initial

power-up to perform Walk Tests.
