Duct Smoke Detector Installation Location

To ensure correct operation install the duct detector using the following guidelines.

Duct smoke detector installation location.

Designers should also remain aware that duct detectors may not substitute for area smoke detection. In the areas where smoke detectors become inaccessible designers should include smoke detection controls remote from the inaccessible area. The international mechanical code section 606 2 2 also states that unless multiple air han dling systems share common supply or return air ducts or plenums duct detection is not required in the supply air system. If the detector is.

The duct detector should when possible be located a minimum of six duct widths downstream from a source of turbulence bends inlets or deflection plates. Prior to the installation of the damper and smoke detector. For proper air sampling duct pressure should be a minimum of 0 01 inches of water. 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.

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. Due to smoke dilution in the ducts the duct detectors will respond more slowly than an area detector. Standard location when factory mounted will be on the side opposite the damper actuator. 2 6 p n 3101210 rev 02 iss 28jan13.
