S750 alarm controller

The gas alarm controller S750 is the latest development of our company. While maintaining functional continuity, the device received a modernized design implemented according to the modular principle, which ensures the flexibility of the configuration and high scalability. A special design of the cable channel on the rear panel provides simplicity and ease of installation.
The unique comb system fixing the wires not only allows you to clearly organize cable wiring, but also greatly simplifies the maintenance.
