Function
The Series FSK700 Key Safe features independently operating sensors and actuators. The logical
operations between the signals of the sensors and actuators are made by the corresponding monitor-
ing equipment (such as Key Safe Controlling and Monitoring Device AD900-1, MEP Article No.
265900), which acts as intelligent interface between the Key Safe and the fire detection control
panel or burglar alarm system.

2.1
Normal condition
The Fire Brigade Key Safe is in normal condition if:
the master key/all master keys are inserted correctly,
the inner door is closed,
the key to the inner door has been removed,
the outer door is closed, and
the unlocking device of the Key Safe has not been activated.
In normal condition, the electromagnet of the outer door closure device is rendered currentless.
2.2
Fire alarm condition
Fire alarm is reported to the fire brigade by the fire detection control panel using a transmitting
device. The fire brigade will transmit the confirmation signal, which, via the controlling and monit-
oring device, electromagnetically unlocks the outer door of the Key Safe – the outer door is thereby
cleared for opening.
The outer door does not open automatically after unlocking.
After opening the outer door, the inner door can be accessed. Using the key in possession of the fire
brigade, the inner door can be opened, and the master key(s) obtained.
In this state, monitoring of opening or sabotage of the Key Safe, as well as – if available – monit-
oring of the Flush Mounting Frame with Drill Protection and the Key Safe Column is disabled.
In special application cases, unlocking of the outer door must only be performed when, supple-
mentary to the confirmation signal, the fire detection control panel is in fire alarm condition. The
Key Safe Controlling and Monitoring Device AD900-1 by MEP is equipped for this special
application, featuring two unlocking inputs, which can be connected via a logical AND operation
(AD900-1 / S2-1 switched "ON").
