Kidde 21032781 Aspirating Smoke Detector Ac Dc

Product Description

The KIDDE 21032781 is an aspirating smoke detection unit designed for AC and DC power operation. Aspirating smoke detectors draw air samples from a protected space through a pipe network and analyze them for smoke particulates, providing early-warning detection before visible smoke develops. This unit is sold individually and is installed by licensed fire alarm technicians and qualified electrical contractors in commercial and institutional settings where advanced smoke detection is required.

Aspirating smoke detectors are commonly installed in environments where conventional point detectors are insufficient or impractical, such as data centers, clean rooms, historical buildings, warehouses, and large open-area facilities. The 21032781 supports both AC and DC power input, making it adaptable to a range of fire alarm panel configurations. Installation is performed as part of a complete aspirating detection system.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes.
