Electric strike STEP 28E Secure

– combines requirements for security, fire safety and evacuation with automatic door openers or pull handles

STEP 28E Secure is a sash lock electric strike that makes it possible to combine requirements for security, fire safety and evacuation with automatic door openers or pull handles. The electric strike is used together with a sash lock, which provide good protection against burglary attempts while a door retaining function is always retained with a lever handle latch bolt.

 

Electrical locking for doors with many requirements

STEP 28E Secure is used in electrical locking where door automation or pull handles are to be combined with requirements for high security and/or fire containment. The electric strike is used together with a sash lock, which provide good protection against burglary attempts while a door retaining function is always retained with a lever handle latch bolt.

Emergency evacuation function and fire safety requirements in fail secure and fail safe functions STEP 28E Secure is often fitted with emergency evacuation locks according to EN 179 where fire safety requirements and evacuation are to be combined with automatic door openers. STEP 28E Secure also allows emergency opening via emergency open buttons at the fire cell limit.

 

For door environments with fire requirements

Certified in fire technical class E/EI60 according EN 14846:2008.

 

Access control even after evacuation

After the door has been unlocked with a key, emergency evacuation fitting, emergency opening button or via fire alarm, a push handle allows for re-entry. A pull handle mounted on the exterior side provides continued access control with opening via code.

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 28E Secure is equipped with STEP’s patented Preload technology that allows the door to be unlocked 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.
