Thermal detector with isolator A50HI, thermal accuracy with integrated protection
The A50HI is a Cofem algorithmic-addressable thermal detector that incorporates a thermovelocimetric sensor and a short-circuit isolator, making it a doubly effective element in any fire detection system. Designed to respond reliably to temperature rises, its sensor is activated at a fixed temperature of 60°C when slow thermal rises are detected, providing sensitive protection adapted to different risk scenarios.
As part of the A50 range, this detector combines modern aesthetics with a three-dimensional architecture resistant to environmental dirt. Inside, it integrates the latest electronic technology together with new algorithms that optimize thermal detection efficiency.
Its ability to operate within addressable systems and its compatibility with other A50 models – such as optical detectors, CO sensors and UL listed units – make the A50HI a robust, safe and scalable solution, especially suitable for installations requiring advanced thermal detection with short-circuit protection.
Key features
- Thermal sensor.
- Built-in isolator.
- Low profile, overall height less than 42 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 and EN 54-17 with CE marking according to the European Construction Products Regulation (EU) No. 305/2011.
