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.
Key features
- Optical and thermal sensor.
- Built-in short-circuit isolator.
- Low profile, overall height less than 55 mm (including socket).
- Also available with high socket for 20 mm pipe.
- Possibility of connection to a remote action indicator.
- Easy connection.
- Red and yellow bicolor LED.
- Indication, by means of the red led, of the communication with the control panel (single blinking), as well as of the alarm status (led on).
- Indication, by means of the yellow LED (single flashing), of the activation of the short-circuit isolator or lack of communication with the control panel.
- Signaling of the sensor’s soiling status on the control panel display (the sensor allows differentiation between rapid signal increases due to alarm and small, slow and sustained increases due to accumulation of dust and dirt).
- Easy-to-install head and socket, interchangeable throughout the A50 range, and made of white heat-resistant ABS.
- UL certified according to EN 54-5 class A2R, EN 54-7 and EN 54-17 with CE marking according to the European Construction Products Regulation (EU) No. 305/2011.
