The GDS-75N wireless alarm monitor receives radio signals from up to 32 GDS Corp wireless gas monitors and activates local alarm relays based on wireless detector readings.

The GDS-75N can be programmed to monitor one of 52 unique networks on 900 MHz radios or one of 76 unique networks on 2.4 GHz radios. Each network supports up to 255 separate gas monitor addresses (channels).

There are three independent user-programmable alarm levels for each channel, and three corresponding dry contact alarm relays for external horns and strobe lights.

The GDS-75N operates over a range of +12VDC to +35VDC, enabling use with low cost 12V solar power systems (always use a low-voltage cutoff controller).
