Electric strike STEP 98 Preload

Fire resistant with fixed cut-out for mechanical deadbolt

STEP 98 Preload has a fixed cut-out that can operate in conjunction with a lock case’s hook bolt or deadbolt, to block the door’s access control system/reader or door automation. This is desirable in door environments where you want to be able to block the door’s access control system/reader or door automation with, for example, a thumbturn or key.

CE-marked according to SS-EN 14846: 2008 in fire resistance class E / EI120.

Reliability and easy installation with minimal dimensions

The combination of STEP’s unique Preload technology and small dimensions provides a lock with high operational reliability and easy installation in almost all door environments.

STEP’s patented Preload technology

A common problem is that a door is subjected to pressure, for example, because the door is a little skew or that gravel or snow has gathered at the doorstep. STEP 98 Preload is equipped with STEP’s patented Preload technology that allows the door to be unlocked even if subjected to pressures of up to 40 kg.

  • Seals and pressure differences– The Preload function enables the door to always be unlocked even when the door lock is tensioned against the electric strike.
  • Door automation– The Preload function combined with rapid unlocking means that the door opens quickly and without risk of becoming stuck.
  • Evacuation door– The Preload function ensures that a fire alarm can release the lock, despite pressure against the door by crowds, seals, pressure differences or warped doors.
Optional accessory: a dead bolt indication

To STEP 98 Preload, it is possible to install a dead bolt indication to the electric strike. This indication can be used to automatically block the door’s access control system/reader or door automation when the hook bolt/deadbolt is mechanically locked.
