Wireless heat detector AHD

  • Ideal for rooms where smoke detectors cannot be used (e.g. kitchen, bathroom, garage)
  • Immediate triggering of an alarm if the temperature rises rapidly and if it exceeds 58 °C
  • Wireless transmission, cyclically (function check)
    and in the case of state transitions
  • Additional room temperature measurement
  • Compact, unobtrusive design
  • Design as per EN 54-5 class A1/R


For detection of heat and fire in living spaces. Audible alarm and direct transmission to the AFRISOhome gateway if the temperature rises rapidly or if it exceeds 58 °C. AHD is ideal for use in rooms subject to generation of smoke or vapour (such as kitchens, bathrooms) or in which dust, dirt and exhaust gases can develop (such as workshops, garages). Recommended if smoke alarms cannot be used due to possible false alarms.


The heat detector AHD consists of a sensor head and a mounting base with integrated EnOcean wireless module. The sensor head features a permanently installed lithium battery with a service life of up to 10 years for reliable, long-term fire protection. A fire alarm is indicated by a flashing LED and a sound sequence with the maximum alarm sound pressure of 85 dB. The alarm is also transmitted via the EnOcean wireless module. A photovoltaic cell generates the required energy. A battery can be
inserted in the base for use in darker environments. Each heat detector has a unique ID so that the recipient can distinguish the individual heat alarms if multiple sensors are used. The AFRISOhome gateway lets you program a great variety of scenarios for an alarm, for example switching on the lights for the escape route, opening of shutters for escaping, push messages, etc. The EnOcean wireless module is not only used for transmission, but also for regular function checks.
