In the fire linkage control system, there are many devices that utilize multi-line control, such as fire pumps, sprinkler pumps, fans, etc. Some of these devices have built-in self-locking AC drive mechanisms, requiring external pulse control signals, while others do not have self-locking mechanisms and require external level control signals. The GM651, through settings on the circuit board, can output either level control signals or pulse control signals to meet the control requirements of multi-line linkage control devices. When outputting pulse control signals, upon receiving a start signal from the GK641 linkage control panel, the action indicator light illuminates, initiating the output of a contact that emits a pulse for approximately 2 seconds before retracting. Upon receiving a stop signal, the output contact ceases to emit a pulse for approximately 2 seconds before retracting. The product features the following characteristics:
Applied in the multi-line linkage control system composed of the GK641 linkage control panel, serving as the input and output interface between the GK641 linkage control panel and on-site linkage equipment;
Without coding, its address belongs to the GK641 linkage control panel;
Three-wire control, with simple and convenient wiring, easily achieves start-stop response function;
Two output control modes are available: level output and pulse output, facilitating the configuration of linkage devices for both level start and pulse start.
