What is the logical relationship between the fire control module and the terminal box? What is the logical relationship between the control module and all kinds of fire fighting equipment?
Fire control equipment, module to output 24V power supply (some action module also have normally open contact output), start by control equipment, control equipment is started, start signal to the control module to send equipment (normally open contact is closed), after receiving the alarm control module to the host sends the equipment start signal.
The signal used for fire control module two bus and 24V power line is supplied by terminal line;
Normally, the control module outputs the inspection voltage to the controlled device (both the action and the feedback circuit) to ensure the normal connection of the equipment;
