QPM Series Indoor Air Quality Duct Sensors

Item Number 129-433, Rev. GA Page 1 of 4

Product Description

The QPM Series Indoor Air Quality Duct Sensors

are designed for applications where precise, stable

sensing of carbon dioxide (CO

), temperature, or

relative humidity sensing is required. Model

QPM2102 senses both volatile organic compounds

(VOCs) and CO

, with the output signal

automatically switching to reflect the higher of the

two values.

These sensors are directly wired to the controller

with 18 to 22 AWG (recommended) multi-conductor

shielded cable. The number of conductors required

depends on the model selected. All field wiring is

terminated in a terminal block on the sensor body.

The output signal is field selectabe for 0 to 10V or 0

to 5V.

Siemens CO

+ VOC sensors are designed to help

maximize occupant comfort and are not suitable for

use in life safety applications.

Expected Installation Time

One hour

Required Tools

· Phillips screwdrivers, No. 1 and No. 2

· Wire cutters/strippers

· Medium flat-blade screwdriver

· Tape measure

· Medium-duty electric drill

· Marker or pencil

· No. 26 (0.147-inch) drill bit

· Small level

· 7/8-inch drill bit or hole saw

· Two No. 8 × 1-inch sheet metal screws

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.

Mounting Information

Locate the sensor:

· In the center of a duct.

· Away from fans, corners, heating and cooling

coils, and so on.

· Away from direct sunlight (for example, not

on a rooftop). To ensure correct operation,

the sensor’s ambient temperature must be

between 23°F and 133°F (–5°C to 45°C).

· Where it receives adequate airflow for

proper operation.

· Where it can be easily accessed for service.

The distance should be as great as possible, but no more than 33 feet (10 m). Attach the sensor mounting bracket and gasket to the duct using two No. 8 × 1-inch sheet metal screws. See Figure 4 . NOTES: To ensure degree of protection IP 54, the sensor must be fitted with the cable entry pointing downward.
