3- Smoke Addressable Sensors With/Without Isolator (A50Si / A50S) - Cofem COMPACT LYON PLUS Manual

1.5.2.3- Smoke addressable sensors with/without isolator (A50SI / A50S)

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 A50SI and A50S models are detectors that have a smoke sensor.
The A50SI model additionally incorporates a short-circuit isolator.
The smoke sensor is specially designed to detect the presence of combustion aerosols in a three-dimensional
design that makes it more robust against dirt.
Specifications:
• Smoke sensor.
• Model A50SI incorporates short-circuit isolator.
• 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).
• Bicolor 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.
• Signaling 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).
• Easy installation head and base, interchangeable throughout the A50 family, and made of white heat-resistant
ABS.
• UL certificate according to EN 54-7 Standard with CE marking according to the European Regulation on
Construction Products (EU) No. 305/2011. Additionally certified EN 54-17 in the A50SI model.
