Kidde | Kidde Intelligent Duct Replacement Terminal Board | KI-DDOSIB

The KI-DDOSIB is the replacement interface board for the Kidde Commercial KI-DDOS Optica Intelligent Duct Smoke Detector. When a duct detector's control section fails or takes a lightning/surge hit, this board lets you restore the unit to service without swapping the whole detector housing or re-running duct penetrations.

Why installers use it

• Drops into the existing KI-DDOS housing — no need to replace the sensing tube or re-cut the duct
• Keeps Kidde Intelligent electronic addressing intact on the SLC loop
• Terminal block layout matches the original KI-DDOS wiring, so field connections don't need to be redone

Where it fits

Keep one on hand for any facility running KI-DDOS duct detectors — it's the fastest path back to a working detector when the interface board, not the optical sensor, is the failure point.
