Edwards Signaling GCI-NB Graphic Annunciator Driver Without Buzzer

Designed to simplify remote status display and improve situational awareness, the Edwards Signaling GCI-NB graphic annunciator driver delivers reliable, rack-mountable annunciation for security and surveillance systems. This annunciator driver interfaces directly with Edwards intelligent control panels over RS-485, configurable for Class A or Class B communication to suit resilient alarm network layouts. It supports up to 32 LEDs on the E-FSA250 (16 LEDs on E-FSA64) so operators can monitor zones and devices visually without delay. With five dedicated switch inputs plus sixteen programmable inputs, the GCI-NB adapts to custom control schemes and integrates smoothly into existing monitoring and access control workflows. The snap-track mounting system and compact plastic rail reduce installation time in standard EIA panels, and the unit can be powered by the control panel or an approved external supply. As the “NB” model, it ships without an internal buzzer — ideal for applications where audible alerts are handled centrally or silence is required. Perfect for command centers, surveillance rooms, and commercial alarm panels — add the GCI-NB to your security infrastructure to enhance monitoring clarity and response capability.
