is the Ajax EN54 FireProtect (Heat\/Sounder) Jeweller used for?\u003c\/h3\u003e\n\u003cp\u003eIt is a wireless EN54-certified point heat detector with a built-in fire alarm sounder. It detects fire by monitoring temperature and rate of temperature rise using two thermistors, and provides an immediate audible warning through its integrated sounder. It is ideal for areas where smoke detectors are unsuitable, such as kitchens, garages and dusty or steamy environments.\u003c\/p\u003e\n\u003ch3\u003eWhen should I use a heat detector instead of a smoke detector?\u003c\/h3\u003e\n\u003cp\u003eHeat detectors are best for environments where smoke, steam, dust or fumes are normally present and would cause a smoke detector to false alarm — for example kitchens, garages, workshops and boiler rooms. Instead of sensing smoke particles, this detector reacts to high temperature and rapid temperature rise.\u003c\/p\u003e\n\u003ch3\u003eWhat does EN54 certification mean?\u003c\/h3\u003e\n\u003cp\u003eEN 54 is the European standard for fire detection and fire alarm systems. This detector is certified under the Construction Products Regulation to \u003cstrong\u003eEN 54-5\u003c\/strong\u003e (heat detectors), \u003cstrong\u003eEN 54-3\u003c\/strong\u003e (sounders), \u003cstrong\u003eEN 54-25\u003c\/strong\u003e (radio-linked components) and \u003cstrong\u003eEN 54-13\u003c\/strong\u003e (system compatibility), making it suitable for regulated and professional fire installations.\u003c\/p\u003e\n\u003ch3\u003eHow loud is the built-in sounder?\u003c\/h3\u003e\n\u003cp\u003eThe sounder produces up to \u003cstrong\u003e89 dB\u003c\/strong\u003e at 1 metre, using an EN 54-3 compliant temporal alarm pattern. It offers 32 selectable tones and configurable volume, and audible alerts are automatically synchronised across all FireProtect sounders in the system.\u003c\/p\u003e\n\u003ch3\u003eDoes it need a specific Ajax hub?\u003c\/h3\u003e\n\u003cp\u003eYes. The detector requires an Ajax control and indicating equipment (CIE) \/ hub running an up-to-date OS Malevich, such as the Hub 2 (2G\/4G), Hub 2 Plus or Hub Hybrid. Always confirm compatibility using the Ajax compatibility tool before purchase.\u003c\/p\u003e\n\u003ch3\u003eHow is the detector powered?\u003c\/h3\u003e\n\u003cp\u003eIt operates from \u003cstrong\u003etwo pre-installed CR123A lithium batteries\u003c\/strong\u003e, providing up to \u003cstrong\u003efive years\u003c\/strong\u003e of autonomous operation under normal conditions. Batteries can be replaced without tools, and status is monitored and reported in the Ajax app with early low-battery notifications.\u003c\/p\u003e\n\u003ch3\u003eCan it be installed outdoors?\u003c\/h3\u003e\n\u003cp\u003eNo. The EN54 FireProtect (Heat\/Sounder) Jeweller is designed for \u003cstrong\u003eindoor use only\u003c\/strong\u003e and carries an IP21C protection rating.\u003c\/p\u003e\n\u003ch3\u003eWhat colour options are available?\u003c\/h3\u003e\n\u003cp\u003eThis product (article 119915.274.WH1) is the \u003cstrong\u003eWhite\u003c\/strong\u003e version.
