Emergency exits must not be locked by law. They must be excessible at all times and it must be possible that everybody can easily open them in case of an emergency to leave the building by the shortest route to get the outside.
Various special building regulations in connection with the new EN norms demand that emergency doors have to be opened with one single grasp. Experience however shows that neither mechanical nor electrical safety devices at emergency exits are a functional solution. GfS has created a new EN door guard that fullfills the demand.
- With the lock position the door guard secures the door handle however in case of an emergency the door can be opened with one single grasp.
- While pressing down the door handle the door guard moves down vertically frees the door handle.
- As soon as the door handle touches the door guard housing a so called pre alarm is triggered which warns against unauthorized use. It stops when the door handle is released.
- After the door handle is pushed down with a single grasp a permanent signal is emitted and people can pass the emergency exit door. The only way to reset the door guard to its protective position and to stop the alarm is with key.
Because of t he new cover fastening (without screws) the door guard is protected from sabotage.
The device can optionally be ordered with a so called pre-alarm-function. As soon as the door handle touches the door guard housing the pre alarm is triggered which warns against unauthorized use. It stops when the door handle is released.
