The Firex KF30LL long life heat alarm with lithium battery backup is provides protection for any kitchen (replaced the discontinued Kidde 4892). Smoke alarms and kitchens do not go well together so the heat detector is perfect as it will not go off with burnt toast and steam. This is also the best alarm for a garage as it won't be affected by fumes and dust.


Fully conforming to BS 5839-part 6 Grade D, it will interconnect to up to 23 other Firex or Kidde Slick mains alarms and fitting is very easy. This detector has a 6 year warranty which includes the battery along with a single hush and test button. The battery is included. Always have ionisation and/or optical alarms in the house, as well as heat alarms.

 
Note - the long life version with a lithium backup battery includes the battery life in the 6 years of the alarm warranty. Standard backup batteries need replacing every 12 months.
 
Heat alarms are suitable for kitchens, garage and dusty rooms - a house should also have a combination of optical and ionisation
 
Do not use in in bedrooms, hallways or shower room
 
Fixing requires two little screws and wallplugs (included) to screw to ceiling or use sticky pads

    Excellent technical support, I needed to replace out of date alarms and the technician provided the new model details and confirmation that it was an easy replacement. Order delivered next day easily within the 1 hour delivery slot I had been given. Very impressed and would use again.
