1.5.1.2.- Addressable temperature sensor (A30XTA)

The Addressable Temperature Sensor (A30XTA) measures the
room temperature, as well as its rate of change.
When the ambient temperature experiences slow rates of change
(less than 1ºC / min), the Alarm level remains constant to 60ºC.
However, for fast variations in temperature (above 1 ºC/min), the
control panel uses an algorithm capable of evaluating the rate of
change of temperature, and of adjusting the Alarm level to different
gradients (rate of rise detection of temperature). In this way, a fast
variation causes a decrease in the Alarm threshold, thereby
accelerating the detection.
The chosen degree of sensitivity will depend on the room temperature of the place where each sensor is
installed, and in each case the alarm temperature will adapt to the chosen degree.
Also in the detection of temperature confirmation by means of two consecutive readings is used (less
than 10 seconds), before activation of the Alarm.
The operation principle is based on the physical properties of an NTC. The variation in electrical
characteristics of the thermistor, due to the variation of the room temperature, is what enables its use as
a sensor element.
The measurement made by the sensor is converted in a Voltage value, which is digitized and transmitted
to the control panel.
The A30XTA device complies with EN 54-5 with the mark of conformity with the regulations awarded
by AENOR with an A2R sensitivity degree.
The head and the base (interchangeable throughout the range of sensors) are made in thermal resistant
ABS.
The flashing of the red transparent LED indicates communication with the Control panel Lyon system,
and if they remain lit they indicate the alert status of the sensor.
