Wall-mounted, NEMA 4X standalone ventilation controller with one, two, or three high-performance SC2-Series gas sensor modules.
Intuitive, menu-driven setup allows on/off, multi-speed, and variable speed control of ventilation equipment in response to user-specified gas concentration levels.
Multi-color LCD and standard horn/light module for local annunciation of escalating alarm levels.
Conforming to Safety Integrity Level 2 (SIL 2) and rigorous international standards, PolyGard®2 monitoring and control systems utilize advanced self-diagnostics and flexible ventilation control functions to ensure maximum human safety without compromising energy efficiency.
Advanced, microprocessor-based X-Change sensor modules meet or exceed the EN 50545-1 self-diagnostic standards including notifying the controller when calibration is due. Although field calibration is possible, X-Change technology allows fast and cost-effective sensor module swaps minimizing field service time, eliminating system downtime and ensuring peak system performance for many years.
To detect and control levels of toxic and combustible gases in various commercial applications. Although typically operating as a standalone controller directly activating ventilation equipment in response to rising gas levels, the SGC6 can also work with building management systems via Modbus serial communications, analog (gas value), or binary (threshold/relay) output signals.
