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.

Approved fire resistance class E/EI 60.

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.

 

Equipped with STEP’s Preload technology

STEP 28E Secure is equipped with STEP’s Preload technology that allows the door to unlock, even if subjected to pressures of up to 500 kg.

Wide range of faceplates

STEP 28E Secure has a wide range of stainless steel faceplates to choose from.

Functional description
  • The upper rotating cam/electric strike is activated electrically via access control system, code lock or similar, and becomes unlocked (fail safe function).
  • The upper rotating cam/electric strike is activated electrically via access control system, code lock or similar, and becomes locked (fail secure function).
  • The lower rotating cam/electric strike is activated electrically via access control system, code lock or similar, and becomes unlocked.
  • The access control system detects, due to the bolt contact whether the door is closed or open.
  • The access control system detects, due to the barrier contact whether the electrik strike is locked or unlocked.
  • Choose if it should fit a right- or left-hung door, be in fail safe or fail secure function, 24 V or 12 V and what bolt width it should be adapted for.
