The KI-OSD is an addressable optical smoke detector for the Kidde Intelligent Series, using a photoelectric sensing chamber to catch slow, smoldering fires at the first sign of smoke.
Built for the commercial installer
The detector continuously adjusts its own sensitivity as dust, humidity, and temperature drift over time, then reports a dirty-sensor warning before it ever reaches a trouble condition — so maintenance gets a heads-up instead of a surprise. A twist-and-lock head speeds installation and service, and comprehensive self-diagnostics store test history on-board for reporting.
Key features
- Photoelectric optical chamber tuned for slow-burning, smoldering fires typical of modern interiors
- Automatic rate-compensated sensitivity adjusts for dirt, smoke, humidity, and temperature drift
- Dirty-sensor warning flags cleaning needs before the detector goes into trouble
- Twist-and-lock detector head for quick installation and base swaps
- Compatible with B4U, RB4U, IB4U, and SB4U bases for standard, relay, isolator, or audible applications
- UL/ULC/CSFM listed for commercial fire alarm systems

Does the KI-OSD adjust for dust and aging?
Yes. It automatically compensates its sensitivity for environmental drift and issues a dirty-sensor warning before it reaches a trouble condition, giving maintenance a heads-up to clean it.
What base does the KI-OSD require?
Any B4U-family base: B4U standard, RB4U relay, IB4U isolator, or SB4U audible. The detector shares the base's address, so no extra address is used.
What panel is this compatible with?
Kidde VS and VM Series intelligent fire alarm control panels.
