The Gerda H System® and the Gerda Barrier gate lock system® are separate high performance locking systems for different applications. Improving access management while enabling immediate Fire & Rescue Service access through the unique Gerda One Key® System.

The H System® offers flexibility in how an organisation can tailor their security requirements for areas of restricted access, in particular for services and utilities rooms.
The Barrier gate lock system assists in managing vehicular access on estates and sites. Design innovation includes the key not being retrieved until the gate is returned to its closed position and locked.
Both systems are accessed by the Fire & Rescue Service through the unique Gerda One Key® System. The majority of UK Fire & Rescue Services carry their Gerda One Key System.
