What Is Fail Secure (NO)?

With the Fail Secure (NO - Normally Open) operating principle, the product is connected to the relay's NO output. When power is applied, the lock opens; when power is cut, the door stays locked. For this reason, it is preferred especially in areas that require high security.

Note: In Fail Secure operation, electric strike locks use the relay's NO output connection.

Applications

  • Office entrance doors
  • Apartment building entry systems
  • Factory and warehouse doors
  • Card access systems
  • Keypad access systems
  • Staff entry and exit control points
  • Any door that requires security
