FAQs
What types of fires does the heat detector respond to?
The EN54 FireProtect Heat Jeweller detector is specifically designed for detecting flaming fires and rapid temperature rise conditions using dual thermistor technology, making it ideal for environments where smoke detectors may cause false alarms.
What heat detection modes are available?
The detector offers multiple configurable heat detection modes including A1, A1R, A1S, B, BR, BS, C, CR, CS, and fixed temperature modes. These can be selected and configured through the Ajax app to match specific environmental and safety requirements.
Where should heat detectors be installed instead of smoke detectors?
Heat detectors are ideal for kitchens, garages, boiler rooms, dusty industrial environments, or any location where smoke, steam, or airborne particles might cause false alarms with traditional smoke detection systems.
How quickly does the detector respond to temperature changes?
The detector responds rapidly to dangerous temperature conditions and transmits alarms to the CIE within 3 seconds of detection, ensuring quick fire safety response.
What certifications does the heat detector have?
The detector is certified to EN54-5 and EN54-25 standards and complies with Directive 2014/53/EU (RED), ensuring it meets European fire safety regulations for commercial heat detection installations.
Can the detection sensitivity be adjusted?
Yes, the various heat detection modes (A1, A1R, A1S, B, BR, BS, C, CR, CS, and fixed temperature) allow for different sensitivity levels and response characteristics to be selected based on the specific application requirements.
