Imprint bolts are used in conjunction with magnetic contacts to monitor window locks.
Magnetic contacts only monitor the opening, and not the closing, of windows and French windows. A partially open window is identified as closed by the magnetic contact.
Imprint bolts installed in the window frame hold the partially open window far enough open to allow the magnetic contact to recognise this and report an open window.
No, the current hardware does not allow this; nothing can be connected to the terminals planned for this. However, future product adaptations will have the property field in the GPA for external safety power supply. If this is checked in the project plan, the operation unit will display the “wireless outdoor siren power failure” fault.
External alarm devices are displays of an in-situ alarm status.
Essentially, alarms have two tasks:
In VdS systems, the local alert will only take place in conjunction with a telephone dialler.
If the wiring is in place, the alarm control unit can also be connected to the telephone system EXC to trigger a remote alarm.
