Door guard with pre-alarm – secure emergency exit monitoring

Door guards with pre-alarm offer an improved form of escape route security for safety-critical areas. A pre-alarm is activated as soon as the door handle is pressed, signaling unauthorized opening early and preventing incorrect operation. If the door is opened further, the main alarm sounds automatically.

These models are particularly suitable for buildings with high public traffic, supervisory responsibilities, or special security requirements. The pre-alarm has a deterrent effect, increases control, and helps to secure emergency exits in a standards-compliant yet practical manner.
