The Kidde KF31R Sentry heat alarm is designed for rooms where a smoke alarm would give false alarms, such as kitchens, garages, utility rooms and loft spaces. Its thermistor heat sensor responds to a dangerous rise in temperature while ignoring steam, dust and cooking fumes.
A sealed rechargeable lithium cell keeps the alarm working during a power cut with nothing to replace, and it interlinks with up to 23 compatible Kidde FIREX alarms so the whole system sounds together. The Quick-Fit slide-on base keeps installation quick and neat.

Frequently Asked Questions
Can this be linked to my smoke alarms?
Yes. It interconnects with compatible Kidde FIREX smoke, heat and CO alarms such as the Kidde KF21R, so all alarms sound when one is triggered.
