Modular detection controller: 2 zone for 16 conventional sensors

The control unit has been designed and built according to the European Standard to verify the presence of toxic, explosive gas and Oxygen  in a versatile and innovative way in the following way: to connect in the traditional way from 4 to 20 mA 16 remote conventional sensors for one zone, or divisible into two zones with 8 conventional probes for each zone. The control unit has two versions: the DIN rail 9 modules version and the box version (BOX KAC019) 

The control unit features two hazard levels

1st LEVEL, pre-alarm. This data is variable. The technician can modify pre-alarm intervention for every sensor according to the type of plant to be controlled.

The level can be selected from 3% to 16% of L.E.L.

2nd LEVEL, general alarm. it is set to 20 % of L.E.L. or 300ppm”

The control unit is equipped with two general alarm relays with/without Positive Safety Switch to enable further independent control of two solenoid valves.

Suitable for industrial environments and in underground car parks
