Fortress Ensures Machine Safety with New Extracted Key Adaptor
Safety Interlocking company Fortress Interlocks has added its new E1 Extracted Key Adaptor to the amGard range of modular safety gate switch interlocks. The E1 has been designed to ensure that the door to hazardous machinery cannot be opened without removing the safety key, and the machinery cannot then be restarted until the key is returned.

Fortress has achieved this by designing a mechanism that traps the actuator in the head until the key is removed which then allows the ‘gate’ to swing over the keyhole. While the actuator remains out of the head, the gate remains over the keyhole preventing the key being returned to the lock.
E1 ensures a specific sequence of operation and can be stacked or combined with other adaptors; up to 5 key adaptors can be used in one configuration. E1 also provides a unique link to Fortress’ high profile mechanical mGard range of interlocks.
E1 works with access key and safety key adapters, amGard LOK or STOP bodies and is suitable for either hinged or sliding door applications. The modular arrangement of amGard allows customers to tailor and configure products to suit their application. amGard is a heavy duty interlocking range that provides both safety and security by controlling access to dangerous machinery and safeguarding personnel. A variety of actuators and adaptable mounting arrangements helps sustain a long life cycle and minimises downtime.
