Duct Smoke Detector Installation Location

In the areas where smoke detectors become inaccessible designers should include smoke detection controls remote from the inaccessible area.

Duct smoke detector installation location. We will show you how to wire a system sensor duct smoke detector to a carrier bryant or icp furnace and then configure it s communicating infinity evoluti. The inlet sampling tube is to be located between blades to avoid blockage of the airflow past the tube. Prior to the installation of the damper and smoke detector. Standard location when factory mounted will be on the side opposite the damper actuator.

To ensure correct operation install the duct detector using the following guidelines. If the detector is. Duct smoke detectors should be located in the hvac area between 6 and 10 duct equivalent diameters of straight uninterrupted run. Due to smoke dilution in the ducts the duct detectors will respond more slowly than an area detector.

For proper air sampling duct pressure should be a minimum of 0 01 inches of water. At these locations air flow is less turbulent and the air smoke mixture should be more homogenous refer to nfpa 90a 72 and 101 for more information. Designers should also remain aware that duct detectors may not substitute for area smoke detection. 2 6 p n 3101210 rev 02 iss 28jan13.
