The SECO‑LARM E‑941SA‑1200 is a single‑door electromagnetic lock with a 1,200‑lb (545 kg) holding force, operating on 12 or 24 VDC, and is UL and cUL listed for reliable security applications. When powered, the electromagnet generates a strong magnetic field that securely holds the steel armature plate mounted on the door, and upon deactivation, the door releases completely with no residual magnetism.
