Image module


  • Addressable Heat Sensor with isolator
  • The A50 family of detectors are based on a new refined aesthetic that integrates the latest electronic technology with new, more efficient detection algorithms and a three-dimensional design that makes it more robust against environmental dirt.
  • The A50 family allows multiple combinations between smoke and heat detection, CO sensor and short-circuit isolator with UL certification.
  • The A50HI model is a detector that has a heat sensor. It also incorporates a short circuit isolator.
  • The heat sensor has thermovelocimetric behaviour, reaching alarm status with a static temperature of 60ยบC in the case of slow fire developments.


  • Heat sensor.
  • Short-circuit isolator incorporated.
  • Low profile, total height less than 42 mm (including low base).
  • Also available with high base for 20 mm tube.
  • Possibility of connection to a remote action indicator.
  • Easy connection (and A50S without polarity).
  • Bi-color red and yellow LED.
  • Indication, by means of the red LED, of the communication with the control panel (single flashing), as well as of the alarm status (LED on).
  • Indication, by means of the yellow led (single flash), of the activation of the short-circuit isolator or the lack of communication with the control panel.
  • Easy installation of head and base, interchangeable throughout the A50 family, and made of white heat-resistant ABS.
  • UL certificateย according to Standard EN 54-5 class A2R and EN 54-17 with CE marking according to the European Regulation on Construction Products (EU) No. 305/2011.
