The Fast-Fix base allows for the alarm to be simply clicked into place for connection to the power supply and interlink cable. Maintenance and replacements are quick \u0026amp; easy, and alarms can be swapped between bases if needed. For extra peace of mind, the Firehawk FHN250RB comes with a 10 year warranty.\u003c\/span\u003e\u003c\/p\u003e  \u003cul\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003ePower: 230V mains powered with back-up battery\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eBack-up Battery: sealed self-charging lithium battery\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eWarranty: 10 year warranty\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eLarge, central test and silence button\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eSealed lithium back-up battery is constantly recharged from mains power\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\n\u003cspan style=\"color:#000000\"\u003eCan hardwire interlink up to 12 Firehawk FHN alarms within a single system, including;\u003c\/span\u003e \t\u003cul\u003e \t\t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eFHN250BB mains powered smoke alarm with alkaline back-up battery\u003c\/span\u003e\u003c\/li\u003e \t\t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eFHN450BB mains powered heat alarm with alkaline back-up battery\u003c\/span\u003e\u003c\/li\u003e \t\t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eFHN450RB mains powered heat alarm with sealed self-charging lithium back-up battery\u003c\/span\u003e\u003c\/li\u003e \t\u003c\/ul\u003e \t\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eX-Profile detection chamber reduces false alarms\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eTSE (Thermal Stability Enhancement) improves detection of smoke\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eFast-Fix bases allows for easy installation and offers a discreet appearance\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eEnd of life warning can be silenced up to 10 hours\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eSuitable for Grade D1 installations complying with BS 5839-6: 2019\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003eUKCA marked, CE marked, and Kitemarked to BS EN 14604: 2005\u003c\/span\u003e\u003c\/li\u003e \t\u003cli\u003e\u003cspan style=\"color:#000000\"\u003e\u003cstrong\u003eThis alarm is also suitable for both the Welsh and Scottish updated 2022 legislation\u003c\/strong\u003e\u003c\/span\u003e\u003c\/li\u003e \u003c\/ul\u003e  \u003cp\u003e\u003cspan style=\"color:#000000\"\u003e\u003cstrong\u003ePlease Note:\u003c\/strong\u003e these FHN series alarms are not compatible with the older FH models.\u003c\/span\u003e\u003c\/p\u003e  \u003cp\u003e\u003cspan style=\"color:#000000\"\u003e\u003cstrong\u003eTechnical Data\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cstyle\u003e   table {     width: 100%;
