COFEM - Model A50SHI -Addressable detector smoke & heat & isolator UL.

SHARE
Addressable heat and smoke sensor with isolator certified EN 54-5, EN 54-7 and EN 54-17. • Short-circuit isolator incorporated. • Low profile, total height less than 55 mm (including low base). • Also available with high base for 20 mm pipe. • Remote indicator is optional. ref PIAL. • 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. • Signalling of the dirty state of the sensor on the control panel display (the sensor allows to differentiate between rapid signal increases due to alarm and small, slow and sustained increases due to the accumulation of dust and dirt). • UL certified according to Standard EN with CE marking according to the European Regulation on Construction Products (EU) Nº 2024/3110

A50SHI addressable algorithmic optical thermal sensor
 
The A50 range of detectors is 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 to environmental dirt.

The A50 range allows multiple combinations between optical detection, thermal detection, CO sensor and UL certified short circuit isolator.

The model A50SHI is a detector that has a short-circuit isolator and two different types of sensors: An optical smoke sensor and a thermal sensor.

The optical sensor is specially designed to detect the presence of combustion aerosols in a three-dimensional design that makes it more robust to dirt.

For its part, the thermal sensor allows the thermovelocimetric response of the detector to be activated at a static temperature of 60ºC in the case of slow fire development.
