The PolyGard 2 Multi-Gas Controller MGC2-K is designed to detect toxic, combustible, or dangerous gases in many commercial and industrial applications. Three analogue sensors with a 4–20 mA signal and eight digital sensors via RS-485 communication from Sensepoint XCL and XRL sensors can be connected to the controller, which helps to reduce installation costs.

The controller monitors the measured values and activates the alarm relays if the set local alarm thresholds for pre-alarm and main alert have been exceeded or if there are alarm messages coming from the eight digital sensors. The PolyGard 2 includes the Honeywell Modbus Master Protocol exclusively for Honeywell Sensepoint XCL and XRL gas detectors.
