ISEO Automatic Upper Strike for Passive Leaf Double-Leaf Fire and Emergency Doors

Product Overview

The ISEO automatic upper strike is designed for installation on the passive leaf of double-leaf doors equipped with exit devices, specifically for use alongside a mortise lock in fire and emergency door systems. Predominantly specified in commercial and institutional facilities requiring certified evacuation routes, this strike ensures secure closure when the door is not in use but enables fast release during emergencies.

What distinguishes this SKU is its automatic activation mechanism, which synchronizes with escape hardware and mortise lock systems, removing manual intervention and reducing the risk of improper door functioning during emergency events. This is a substantial advantage for facility managers overseeing multi-door emergency exits, as it ensures compliance and safety with minimal maintenance. Especially suited for procurement in commercial and public sector projects where certified fire and emergency door assemblies are required.
