1.5.1.3.- Analogue multi-sensor (A30XHTCO)
The analogue multi-sensor
A30XHTCO has three
detection types: monoxide, temperature and smoke.
The analogue multi-sensors is able to measure three
types of parameters so the control panel calculates an
average by means of a dynamic processing algorithm which
will vary with the three phenomena. This processing
algorithm will avoid false alarms to a great extent thanks to
the incorporation of the monoxide sensor.
The processing algorithm is able to compensate for
dirt on the optical camera by combining the measurements
of the three different sensors.
The sensor element is formed by an optical camera
provided with an infrared emitter and receiver. In the
absence of smoke the intensity of infrared captured by the receiver is null, due to the physical labyrinth
created between the two. When smoke is present, the infrared reflections from the particles of the same cause
the receiver to obtain a certain luminance intensity, (Voltage value proportional to the level of obscuration),
all of which is controlled by the microprocessor system.
In addition, it has a carbon monoxide sensor with a fast response in the presence of CO which is
present in the vast majority of fires.
Finally this sensor has a thermal probe, acting as a thermal sensor, triggering at 60ºC, considerably
increasing its response to fire.
The A30XHTCO is conformant with EN 54-7 with the conformity mark awarded by AENOR.
The head and the base (interchangeable throughout the range of sensors) are made in thermal
resistant ABS.
The flashing of the red transparent LEDs indicates communication with the Centralised Lyon
system, and if they remain lit they indicate the alert status of the sensor.
Connection is made according to figure 2.
