2.3
Activation of the unblocking device
The unblocking device (a specially realised key switch – see, for example, Unblocking Device
FSE/PHZ900-1, MEP Article No. 265662) is connected to the fire detection control panel in the
same way as a manual call point. Upon activation of the unblocking device, fire alarm will be
activated, thus unlocking the outer door of the Fire Brigade Key Safe via the confirmation signal of
the transmitting device connected to the fire brigade.
Activation of the fire detection control panel by the unblocking device must not affect Fire Con-
trol procedures of the fire detection control panel.
2.4
Fire alarm reset
The outer door of the Key Safe will only lock again after the fire detection control panel is reset,
thereby terminating the confirmation signal, the/all master keys have been reinserted, and the inner
and outer door have been closed. Successful locking can be confirmed by pulling the outer door.
By locking the outer door, monitoring of opening or sabotage of the Key Safe, as well as – if
available – monitoring of the Flush Mounting Frame with Drill Protection and the Key Safe
Column will be reactivated.
Should a master key not have been inserted correctly after resetting the fire detection control panel,
a sustained buzzing tone generated by the Key Safe's integrated buzzer will sound upon closing the
outer door.
This function is only available if the Key Safe is connected to the Key Safe Controlling and
Monitoring Device AD900-1 by MEP (also see page 28 and onwards in chapter 5.3.2: "Acoustic
warning signal when missing master key").
If the Key Safe remains unopened during fire alarm, the outer door will be automatically locked
again upon termination of the confirmation signal, and monitoring of opening or sabotage of the
Key Safe, as well as – if available – monitoring of the Flush Mounting Frame with Drill Protection
and the Key Safe Column will be reactivated.
2.5
Sabotage alarm
The following states are constantly monitored by the Key Safe Controlling and Monitoring Device
AD900-1:
Outer door closed,
Drill Protection Board undamaged,
master keys correctly inserted,
Drill Protection of the Flush Mounting Frame undamaged (if available),
Tamper Switch of the Key Safe Column closed (if available).
The Key Safe Controlling and Monitoring Device AD900-1 will generate an alarm signal if – e.g.,
by forcefully breaking into the Key Safe – one of these monitored states is violated insofar as caus-
ing the monitor loop's resistance to deviate more than 40% from normal condition.
DIN 14675 / chapter C.2.2.3: The report (sabotage report) must, under application according to
Class FSD 3 (high risk), be forwarded to an office or authority that is available at all times, such
as a police department or security company.
If the Key Safe has been unlocked by the confirmation signal, sabotage monitoring is disabled
until a reset is performed correctly (see page 13 and onwards in chapter 2.4: "Fire alarm reset").
