The Kidde KI-SDH is a standard duct housing that provides the mounting enclosure for Kidde KI-series and Optica intelligent smoke detectors on HVAC ductwork. The red steel housing holds the detector, sampling tube, and exhaust tube connections in one duct-mounted package - no separate enclosure or field fabrication required.
Built for the commercial installer
The KI-SDH gives installers a universal mounting platform for duct smoke detection across Kidde intelligent systems. It accepts both legacy KI-series and current Optica intelligent detectors, so a single housing SKU covers multiple detector generations. The housing mounts directly to the duct wall with standard #10 sheet metal screws through pre-punched mounting holes.
Key features
- Universal detector compatibility: accepts both KI-series and Optica intelligent duct smoke detectors in a single housing
- Direct duct mounting: attaches to HVAC ductwork with #10 sheet metal screws through pre-punched holes
- Sampling tube socket: accepts standard Kidde sampling tubes in multiple lengths for various duct widths (tubes ordered separately)
- Exhaust tube connection: built-in exhaust port completes the air sampling circuit for proper duct smoke detection
- Front-accessible wiring: field wiring connections and detector access from the front of the housing
System requirements
Requires a compatible Kidde intelligent duct smoke detector (KI-series or Optica, ordered separately) and a sampling tube sized to the duct width. The detector connects to a Kidde intelligent fire alarm control panel via the SLC loop.
