Bard AB3000-A - Base Alarm Board

The Bard AB3000-A alarm board is an OEM monitoring add-on used with Bard MC4002 series solid-state dual unit lead/lag controllers to provide alarm status and fault indication for the two HVAC units being managed. It is commonly field-installed when a site needs clear alarm outputs for service response or integration with a building alarm strategy, helping technicians quickly identify issues such as unit alarm conditions and wiring or safeties trips without guesswork. Because AB3000-A is a Bard factory part designed for the MC4002 control platform, it is the right choice when replacing a failed alarm board or adding alarm capability to an existing controller setup, and fit and terminal functions should be verified against the MC4002 wiring diagram for your exact configuration before ordering.
