Kidde has enhanced our dependable hardwired alarm platform to make it even more effective for professional installers, while maintaining the familiar system that has proven reliable.
Hardwired D1 and D2 alarms are still required by UK building regulations, and with around 300,000 new homes expected annually, demand remains strong. The Sentry range streamlines options with a clear 4-SKU line-up for Smoke and Heat alarms, offering the proven FIREX platform that installers trust—making installation quicker and resulting in a tidier finish.
Retrofit projects often get messy, but Kidde FIREX Sentry is engineered to simplify them and ensure ongoing reliability in protection.
Leveraging the robust Kidde FIREX hardwired base, Sentry brings an installer-focused design approach.
Why opt for Kidde FIREX Sentry?
The new Sentry collection includes the KF21 and KF21R smoke alarms, along with the KF31 and KF31R heat alarms, featuring:
- A quick-fit slide-on base for speedier and neater installations
- A 150mm flared base plate, perfect for cleanly replacing larger, older alarms
- Built-in cable management to keep wiring organized and connections safe
- Full compatibility with Kidde’s existing FIREX alarms and accessories, including the K4MCO CO alarm and RTHL Fire & CO Alarm Control Unit.
