GST DI-9319E Digital Zone Monitor Module

The GST DI-9319E is an addressable digital zone monitor module designed to connect a zone of conventional fire alarm detectors or manual call points to an addressable loop. Engineered to bridge conventional field devices with GST addressable fire alarm systems, this module powers and supervises a spur line of up to 25 conventional detectors or manual call points while occupying a single address on the main loop. It continuously monitors the conventional zone wiring for open-circuit, short-circuit, and fire alarm states, transmitting distinct status signals directly to the main control panel. Featuring an optional external 24VDC power input, electronic soft-addressing from 1 to 242, and an onboard LED indicator for clear diagnostic status feedback, the DI-9319E offers a practical and cost-effective solution for retrofitting conventional zones into intelligent fire networks.
