Application

Designed specifically for mental health environments in patient bedrooms.

Description

Anti-ligature, mechanical lockset with five-way SOS (Staff Override System) anti-barricade, providing five override methods to ensure service user safety and allowing staff to always gain access to rooms, regardless of keyway damage or tampering.

Features and benefits:

  • The lock and internal turn-pull mechanism operate independently, meaning the key always dominates. This direct mechanical override means no geared cylinder or clutch mechanism is required to disengage the turn-pull.
  • Concealed backup override directly turns the spindle, allowing entry if the keyway is blocked with foreign objects.
  • T-bar offers better grip than an anti-ligature handle and the emergency tool provides superior leverage to rotate the turn-pull mechanism, helping to overcome determined barricades. It also provides pull force to ensure staff can open the door against internal resistance.
  • Safety spindle shears under heavy resistance, ensuring entry if turn-pull is immobilized, and will suit all door thicknesses.
  • Anti-wrench, anti-tamper and robust, with concealed fixings on the bedroom side.
  • 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.
