Applied to the G7 series fire alarm system, GM718B is used to control devices that require controllable DC24V continuous power supply and receive feedback signals from the controlled devices. Such as fire alarm bells, non coded sound and light, linear infrared beam smoke detectors, etc; Active DC24V/40mA output mode. The receiving end is a normally open passive contact signal. By setting the GS701 electronic encoder, open circuit and short circuit detection of the signal output terminal can be achieved; Equipped with output line fault detection; Detect the open circuit of the signal input terminal (all require a 4.7K terminal resistor). The input comes with an isolation circuit, effectively filtering out external interference. By setting up the GS701 electronic encoder, self feedback function can be achieved. It needs to be used in conjunction with the GM710 universal module base. The bus has no polarity.
