MAR2 control module for digital sensitive cable
MAR-2 is a detection control module that identifies the exact point of alarm along the linear heat sensitive cable.
It is of fundamental importance for long distance (for example road tunnels) to find in a very short time the area under fire condition.
Otherwise instead, MAR2 is ideal to detect incipient fires or increments of temperature in cable trays or in areas that are difficult to reach.
MAR2 is able to distinguish a fire alarm (short circuit) from a cable fault (broken cable).
