Nortech NGA-703 Addressable Triple Input/Output Module

The Nortech NGA-703 Addressable Triple Input/Output Module is an intelligent interface device designed to monitor three independent input circuits and control three output relays on addressable fire alarm systems. Operating directly on an addressable communication loop, this multi-functional module incorporates three supervised inputs to monitor dry contact devices such as flow switches or damper status contacts, alongside three Form C relay outputs for automated control of HVAC shutdown, smoke dampers, and door release systems. It features continuous wire-fault supervision using end-of-line resistors, low standby current consumption, and individual LED status indicators for real-time monitoring and diagnostics. Designed with a robust housing suitable for wall mounting or enclosure integration, it delivers space-saving efficiency and flexible multi-point control for modern building automation and fire protection installations.
