+44 (0)330 0580988 Website

Application

Suitable for lower risk doors or staff areas where tampering is unlikely, or as a 'lock-off' function.

Description

Anti-ligature, mechanical lockset with one-way SOS (Staff Override System), providing a key override method. The key operates the lock independently of the internal turn-pull so staff can unlock the door even if the internal turn-pull is being held.


Features and benefits:

  • Direct mechanical override as the lock and the internal turn-pull mechanism operate independently, allowing staff to open doors, even when service users hold the turn-pull mechanism.
  • Provides rapid access.
  • Avoids the issues associated with clutch and geared cylinders in challenging environments.
  • Anti-wrench, anti-tamper and robust, with concealed fixings.
  • Has fire-resistant casing to BS EN 1634-1.
  • CE-marked to BS EN 12209.
  • All locksets are identified by simple to understand product codes that indicate the override type, the application, the handle type and the finish. Consult manufacturer for details.
