Electric strike STEP 15 Secure

A heavy duty deadbolt electric strike

STEP 15 Secure withstands extreme breaking forces and is suitable for doors with high security requirements. The sturdy construction is fast and durable, an advantage when there are frequent entries and exits with secure locking between each entry and exit.

Approved fire resistance class E/EI60.

Function

STEP 15 Secure has a rotating cam that encloses the door lock’s thrown bolt or hook bolt. For maximum security, the door lock must be equipped with a double cylinder. The door is normally opened via access control, but can also be opened with a key or thumbturn.

Genom att kombinera ett elslutbleckets slitstyrka och snabbhet med säkerheten hos ett regellås passar STEP 15 Secure i dörrmiljöer med extremt höga säkerhetskrav, som banker, fängelser och försvarsanläggningar.

By combining the durability and speed of an electric strike with the security of a lock, STEP 15 Secure fits in door environments with extremely high security requirements, such as banks, prisons and defense facilities.

High security

STEP 15 Secure normally locks the door directly upon closing by the lock bolt being enclosed in a rotating cam of hardened steel. The extremely sturdy design makes the electric strike both durable and highly resistant to attempts to force the lock.

STEP’s 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 15 Secure is equipped with STEP’s Preload technology that allows the door to unlock, even if subjected to pressures of up to 500 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.
Supplementary reinforcement plates

If additional attachment reinforcement is needed, special reinforcement plates are available for installation on the inside and outside of the frame. These are clamped together with threaded rods and sleeve nuts to form a strong joint.
