Product Description
This document describes the hardware installation procedures for the
GS-AQR Indoor Air Quality Sensor
The Indoor Air Quality Sensor uses an advanced MEMS metal oxide
semiconductor sensor to detect poor air quality. The sensor reacts
quickly to detect a broad range of VOCs such as smoke, cooking
odors, bio-effluence, outdoor pollutants and from human activities. The
sensor captures all VOC emissions that are completely invisible to CO
sensors.
General Installation Requirements
For proper installation and subsequent operation of each device, pay
special attention to the following recommendations:
-
Upon unpacking the product, inspect the contents of the carton for
shipping damages. Do not install damaged device.
-
Avoid areas where corroding, deteriorating or explosive vapors,
fumes or gases may be present.
-
Ensure that all equipment is installed according to local, regional,
and national regulations.
Personal injury or loss of life may occur if you do not follow a
procedure as specified.
Equipment damage or loss of data may occur if you do not
follow a procedure as specified.
Take reasonable precautions to prevent electrostatic
discharges to the controller when installing, servicing or
operating the controller. Discharge accumulated static
electricity by touching one's hand to a well-grounded object
before working with the controller.

Mounting Instructions
The GS-AQR Series room sensor will install directly on a standard
electrical box and should be mounted about five feet from the floor of
the area to be controlled. For best operation, do not mount the sensor
near doors, opening windows, supply air diffusers or other known air
disturbances. Avoid areas where the detector is exposed to vibrations
or rapid temperature changes.

The cover is hooked to the base at the top edge and must be
removed from the bottom edge first. Use a small Phillips
screwdriver to loosen the security screw as shown in Figure 2.
(Complete removal of this screw is not required).

If the device is equipped with the optional relay, then the normally open relay will close when the air quality exceeds a pre-set trip point. The trip point and hysteresis value can be programmed via the menu such that the relay closes when IAQ >...
