It is applied to the G7 fire alarm system series. GM718A is used to control one-time action equipment and receive the action feedback signals from controlled equipment such as fire power-cut trippers, smoke exhaust valves, air supply valves, DC24V DC relays, etc., and the active DC24V pulse output mode GM718B is used for controlling the DC24V continuous power supply equipment which needs to be controlled and receiving the action feedback signals from the controlled equipment such as fire alarms, non-coded audible and visual alarms, linear infrared beam smoke detectors, etc. The module has the active DC24V/40mA output mode. The receiving end receives a normally open passive contact signal. Through the setting of the GS701 electronic encoder, open-circuit and short-circuit detection of the signal output end can be realized. The module has the functions of detecting output line faults and open-circuit of the signal input end (a 4.7K terminal resistor needs to be connected in the above cases). Its input has its own isolation circuit to effectively filter external interference. Through the GS701 electronic encoder setting, the self-feedback function can be realized. The module needs to be used with the GM710 universal module base. The bus is non-polar.
