QPA20xx Series Indoor Air Quality

Room Sensors

Item Number 129-435, Rev. FA Page 1 of 4

Product Description

The QPA20xx Series Indoor Air Quality Room

Sensors are designed for applications where

precise, stable sensing of carbon dioxide (CO

temperature, or relative humidity is required. The

QPA2002 models sense both volatile organic

compounds (VOCs) and CO

, with the output signal

automatically switching to reflect the higher of the

two values.

Siemens CO

+ VOC sensors are designed to help

maximize occupant comfort and are not suitable for

use in life safety applications.

Expected Installation Time

30 minutes

Required Tools

· Phillips screwdrivers, sizes 1 and 2

· Small and medium flat-blade screwdriver

· Wire cutters/strippers

· Tape measure

· Medium-duty electric drill

· Drill bit for wall anchor hole

· Marker or pencil

· Two No. 10 screws and wall anchors

Prerequisites

· Ensure that the appropriate field wiring is

installed.

Appropriate wiring is 8 to 22 AWG

(recommended) multi-conductor shielded cable

(plenum or non-plenum as required), within the

maximum wiring run length for the individual

equipment controller. See Wiring Diagrams to

determine the required number of conductors.

The maximum recommended length is 750 feet

(229 m).

· Ensure that all wiring complies with National

Electric Code (NEC) and local regulations.

· Allow up to 96 hours for unit to reach published

accuracy.

Installation

Always mount the sensor vertically.

Locate the sensor:

· According to design specifications and local

regulations.

· Where the air circulates around it freely (not in

recessed areas or behind doors).

· Allowing a minimum of 4 inches (10 cm) of free

space above and below for proper airflow and

access.
