Schlage M422 Electromagnetic Lock

Schlage M422 Electromagnetic Lock is a 500‑lb holding‑force magnetic lock designed for traffic‑control door applications and suitable for single or double‑door setups. The lock body measures 18-1/16 inches in length, 2-1/2 inches in height, and 1-3/8 inches in depth, weighing approximately 12 pounds per unit, and it is part of Schlage’s M400‑series electromagnetic locks. It operates on 12/24 VDC with auto‑select input, drawing 1.5 A at 12 V or 0.76 A at 24 V per lock, with a rated holding force of 500 pounds per coil. For double‑door installations, each leaf can be secured by its own M422 unit, enabling consistent lock performance across leaves. Like other maglocks, the M422 requires a continuous power source to stay locked, and a power loss will release the lock, providing controlled egress and compatibility with standard access control hardware and controllers. Installation resources, including templates specific to the M400‑series and downloadable data sheets, are available from Schlage to assist proper mounting and wiring.
