The ST3REL is an optional 3-relay board designed for Smart S, Smart 3, and NCI series gas detectors. It enables the management and output—via dry contacts—of various signals originating from the detector.
The three relays can be configured for Fault/Watchdog signaling, first or second alarm thresholds, and an additional alarm threshold, respectively. Relay function configurations can be modified via the detector's operating menu, offering flexible output management tailored to specific system requirements.
The board installs directly onto the detector's mainboard and comes with a ribbon cable to facilitate connection and integration into the gas detection system.
