: r , The ventilation mode signal control box is used as a special device for underground engineering (civil air defense). It is used for command transmission and alarm signal display for switching between different protective ventilation modes in wartime fortifications.
: r , ) Composed of two signal devices
: r , The ventilation mode signal control box is composed of a through-type signal control box at the command end and several signal boxes at the receiving end. The control box has two types of output: channel and channel output. Since the command terminal also has a signal input and adopts unified signal parameters, this device can be used for the ventilation signal system of individual fortifications, and can also be used to form a hierarchical signal system in a group of civil air defense fortifications to achieve unified command and operation in area wartime. .
: r, ) Features of the three devices
: r, has a signaling monitoring function, which can detect signal transmission failures in time
: r, B has a receiving end reply signal, which can timely grasp each duty position The execution status
: r, can carry out system self-check and test, which is convenient for maintenance and management
: r, has strong versatility, the system can be expanded arbitrarily, and is suitable for various scales of civil air defense fortifications and areas.
