CISA 11931 Series Electric Lock

The CISA 11931 Series Electric Lock is a heavy-duty, surface-mounted solution designed for wooden gates and doors where secure, controlled access is essential. Suitable for residential and commercial use, it offers reliable electric release alongside a mechanical key override.

Operated externally by a 55mm tube cylinder and internally by a push button, which can be overridden with a key for passage mode, this outward opening lock allows quick exit via the button or electrical input while maintaining secure external access.

The lock features a dead-locking latch bolt for enhanced security, automatically blocking the latch when locked. Reinforced protection around the electric hook bolt area and certification to Security Grade 3 in accordance with EN 14846 provide additional resistance against forced entry.

With an adjustable backset from 50mm to 80mm, the 11931 Series offers flexibility across a wide range of installations. The surface-mounted design supports straightforward fitting on both new and existing doors.

The internal key provides a hold open function, allowing the door or gate to remain open when required. The lock also operates under reduced voltage conditions, ensuring reliable release even when supply drops below 12V.

Designed for harsh environments, the lock features a corrosion-resistant coating and durable internal components, making it suitable for high-traffic and external applications.
