Kidde Slick 3SFWR Heat Alarm with Wireless Capability and Rechargeable Lithium Cell

As the world’s largest manufacturer of domestic fire safety products, Kidde have been safeguarding people and property from fire and related hazards for nearly a century. For convenient fast-fit alarms, try something from their ‘Slick’ range, like this Mains-powered Heat Alarm (3SFWR). It can be interconnected with up to 23 other Kidde and Firex mains alarms or used with the Optional Wireless Alarm Base (RF-SFTP) for wire-free interconnection. The 3SFWR can be used in humid or dusty environments where optical and ionisation smoke alarms are unsuitable, e.g. kitchens, loft spaces, and garages. It is not triggered by cooking steam or fumes, thus avoiding ‘burnt toast’ nuisance alarms. To ensure continued protection during power outages, this unit comes with a Rechargeable Lithium Cell Backup. The ‘Slick’ range needs to be installed by a professionally qualified electrician and complies with UK Building Regulations for new housing and associated standards (Grade D BS 5839, Part 6).

How it works:

Heat alarms are designed to detect increases in the surrounding air’s ambient temperature, not the smoke from a fire. They will sound if they detect temperatures in excess of 58°C.

  • Unique fast-fit system with separate base plate for easy fitting and maintenance
  • Integral, double-decker screwless terminal block for fast, push-fit connection
  • Auto reset after activation with latching LED allowing the initiating alarm to be identified
  • Separate Test and Hush buttons to test and temporarily silence nuisance alarms
  • 230V mains-powered with sealed-in rechargeable lithium cell back-up, providing 6 months of continuous operation in the event of mains failure
  • Interconnectable with other Kidde mains smoke and heat alarms, as well as Kidde mains CO alarms using ‘Smart Interconnect’ technology
  • Tamper-resistant locking device prevents unauthorised removal without the use of a tool
  • Wireless capability – use with optional Wireless Alarm Base (RF-SFTP) for RF interlink function
