8612-068BX OBSOLETE
- Main Alarm Board - Boxed
The Bard 8612-068BX Main Alarm Board is a genuine OEM control component used in Bard MC5000 series lead lag controllers, specifically the MC5300-BC and MC5600-BC configurations, where it provides dry contact alarm outputs for remote monitoring of controller and connected wall mount unit conditions. This board is designed to integrate with the controller wiring terminals to report alarms using normally open or normally closed contact strategies, helping facilities and telecom shelter applications tie critical HVAC status into a BAS, alarm panel, or remote monitoring system. If you are replacing a failed alarm output board or restoring factory alarm functionality after troubleshooting, 8612-068BX is the correct Bard specified part to match the controller design and maintain reliable signaling for Systems 1 through 3.
