Sargent 52-2401 Replacement Controller | For KP8200 Mortise Locks

The Sargent 52-2401 is a genuine OEM Replacement Controller Board specifically designed for the Sargent KP8200 Series Standalone Electronic Mortise Locks. This main circuit board acts as the central processing unit, managing over 1.1 million user code combinations, audit trails, and the motor-driven latch retraction.

CRITICAL AVAILABILITY NOTE: This is a discontinued item and is extremely difficult to find in new condition. We currently have limited stock available for immediate shipment. For facilities using the high-security KP8200 platform, this controller is a vital part to keep on hand to avoid an expensive, full-door hardware replacement.
