Why choose a 4-inch smoke alarm?
The 10SDR compact 4-inch size is ideal for spaces where a standard-size alarm would be too large or too visible, such as manufactured homes, mobile homes, small rooms, or closets requiring smoke detection. It provides the same DETECT-line protection in a smaller footprint.
Does the 10SDR need a battery?
Yes. The 10SDR runs on 2 AA batteries, which are included. Replace the batteries every 6 months or when the low battery warning chirp sounds. Using fresh, quality alkaline batteries ensures reliable operation.
What sensor does the 10SDR use?
The 10SDR uses the DETECT-line photoelectric sensor with enhanced sensing technology. This reduces false alarms from cooking while delivering fast detection of smoke from a wide range of fire types.
Does the 10SDR support interconnect?
No. The 10SDR is a standalone battery-powered alarm with no hardwired or wireless interconnect capability. For interconnected 4-inch alarm options, check Kidde current product listings.
What did the 10SDR replace?
The 10SDR replaced the older Kidde P9040 and i9040 4-inch battery smoke alarms, offering improved DETECT-line sensing and AA battery power instead of the older 9V battery platform.
