1.5.2.4- Heat addressable sensors with/without isolator (A50HI / A50H)
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 against environmental dirt.
The A50 range allows multiple combinations between optical and
thermal detection, CO sensor and short-circuit isolator with UL
certification.
The A50HI and A50H models are detectors that have a thermal sensor.
The A50HI model additionally incorporates a short circuit isolator.
The thermal sensor allows the detector's thermos-velocimetry response, becoming activated at a static temperature
of 60ºC in the case of slow fire developments.
Specifications:
• Thermal sensor.
• A50SI has a built in short circuit Isolator.
• Low profile, height less than 42 mm (socket included).
• Also available with bigger socket for 20 mm tube.
• Option for attaching a remote action indicator.
• Simplified connection diagram (A50S does not require polarity).
• Bicolor led (Red and Yellow).
• Indication, by means of the red led, of 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.
• Signaling of the dirty status 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).
• Easy-to-install head and plinth, interchangeable throughout the A50 range, and made of white heat-
resistant ABS.
• UL certified according to Standard EN 54-5 class A2R, EN 54-7 and CE marking according to the
European Regulation on Construction Products (EU) No. 305/2011. In addition the A50SI is EN 54-
17 certified.
