The controllers connect with a wide array of MSA Z-Gard S Sensors, with controller models accepting up to 24 sensors. Relay outputs indicate warning, alarm or sensor fail for each zone, and units are available with one or two zones. A large LED readout displays the active channel and the corresponding sensor gas level.
