Control Unit from 1 to 8 Conventional sensors BX880-AX
With
program
Through the connection of 8 remote sensors, the BX880-AX control unit has been designed and built according
to European regulations to detect the presence of toxic and/or explosive gas in a flexible way
A microprocessor is used to create a complete surveillance and control system with maximum flexibility.
Thanks to this and its other features, the BX880-AX is suitable for civil and industrial applications.
The BX880-AX control unit has two danger levels:
1
LEVEL, 1
Pre-Alarm. It's set at 13 % L.E.L/200 ppm.
st
st
2
LEVEL, Main Alarm. It's set at 20% L.E.L./300 ppm.
nd
Other technical features make this control unit extremely versatile and reliable; for example, by using a series
of micro-switches it is possible to:
Select or disable a sensor when not installed or faulty;
Select the gas type to be detected (toxic or explosive);
Choose the relay functioning mode (pulsed or continuous);
Choose deadband exclusion mode
A TEST button checks the efficiency of both the unit and connected probe to ensure total control of the BX880-
AX
Thanks to the Omega-type format, small and large systems can be built by exploiting the modularity of the
DIN rail in the previously set electrical panels.
In addition to the alarm signal light, it is fitted with an internal buzzer.
Important: Assembly / maintenance of the appliance must be carried out by qualified personnel
and in accordance with applicable laws and regulations.
The manufacturer assumes no responsibility for the use of products that have to comply with
particular environmental and / or installation standards.
Important note
Before connecting the equipment, it is recommended that you read the instruction manual
carefully and keep it for future reference. It is also recommended to perform the electrical
connections correctly as per enclosed drawings, observing the instructions and the Standards.
