Interlock blocking device for doors

Variant for hinged and sliding doors

Compulsory safety devices
In order to prevent lockout during maintenance in safeguarded areas, a safety padlock is often used. The opposite of the use of Lockout-Tagout padlocks is that it is a procedure and not a compulsory one. With the ALPHA, the use of a safety key is made compulsory. 

In contrast to Lockout-Tagout, this fully mechanical locking system for hinged and sliding doors prevents the door from being locked and ensures that machines cannot be restarted unintentionally during operations. In addition, the ALPHA containment system can easily be retro-fitted to any access door to the safeguarded area (which is already equipped with a safe door switch). Finally, ALPHA requires operators to carry a safety key when entering the area.

Specifications of the Alpha, entrapment protection for doors:

  • Compulsory
  • Lockout-Tagout

  • Easy to install on any door
  • Mandatory key removal
  • 200,000 unique key codes
