GDS-75N

Wireless alarm station that receives up to 32 detector channels and drives three independent alarm relay levels.

GDS-75N — GDS-75N Wireless Alarm Station for General Purpose Areas
Overview

What This Device
Does

The GDS-75N wireless alarm monitor receives radio signals from up to 32 GDSCorp wireless gas monitors and activates local alarm relays based on the wireless detector readings. Three independent user-programmable alarm levels per channel drive three dry-contact relays for external horns, strobes, and plant shutdown interfaces. The unit operates from +12VDC to +35VDC, making it compatible with low-cost 12V solar power systems.

Where You'd
Use This

1

Central alarm panel for a wireless detection field in a general-purpose area

2

Solar-powered remote sites where mains power is unavailable

3

Plants that need local audible and visual alarms driven by remote detector readings

4

Staged alarm strategies where different gas levels trigger different responses

Engineering Insight

Why We Specify This

We use the GDS-75N as the local alarm aggregation point on wireless installations. The three-level alarm programming lets us build a graded response (advisory, high, and critical) that maps directly onto the client's cause-and-effect matrix. The wide DC input range is a real advantage on remote mining and pipeline sites where we can pair the unit with a solar supply and avoid a mains installation entirely.
