Door Monitoring & Door Alarms
5.
If door contacts are fitted to the door that the NanoQuest is controlling, the NanoQuest can moni
-
tor the door and raise an alarm when security has been breached by the door being left open after
unlocking or being forced open when it is locked. While an alarm condition is present, the NanoQuest
sounds a continuous tone while the LED flashes amber. The door contacts (closed while door is
closed) must be wired to the door contact input of the NanoQuest, and the ‘Use door contacts’ feature
must be enabled.
Door monitoring also provides a more secure way of unlocking the door. Whenever the door is
unlocked by the presentation of a valid card or by the ‘Request to Exit’ button, the moment the door
is opened the lock is immediately reengaged (strike relay released) to lock the door as soon as it is
closed, regardless of the length of the relay Strike Time. This removes the opportunity for unauthor
-
ised personnel to reopen the door after it has been closed in circumstances where a long relay Strike
Time has been set.
IMPORTANT
If the Strike relay is set to ‘Toggle Lock’ Mode when Door Monitoring is used. The ‘Door
Left Open’ alarm does not operate, nor does the lock immediately reengage when
the door is opened. However, the ‘Door Forced Alarm’ will still be raised if the door is
detected as being open when in the ‘locked’ state.
Door Forced Alarm
5.1
The ‘Door Forced’ alarm occurs when the NanoQuest detects that a door has been opened without
being legitimately unlocked by the use of a valid card or the ‘Request to Exit’ button. This will usually
indicate that someone has physically forced the door open.
Once a ‘Door Forced’ alarm has been triggered, it must be reset by presenting a valid User or Auxil-
iary card to the Nanoquest. The door must also be closed to completely restore normal operation. If
the door remains open after the alarm has been reset, the LED will continue to flash amber and the
condition will be treated as ‘Door Left Open’ (see below).
Door Left Open Alarm
The ‘Door Left Open’ alarm occurs when a door is left open for longer than ten seconds after the ‘door
open’ time. This alarm is useful for preventing personnel from unlocking a door with a valid User/
Auxiliary card or by pressing the ‘Request to Exit’ button and then ‘propping’ the door open, thereby
compromising the security of the controlled area. When a ‘Door Left Open’ alarm occurs, the alarm
can be cancelled by simply closing the door.
Alarm Output Operation
5.2
The NanoQuest unit has an alarm output that can be connected to an external device such as a siren
or flashing light that can be used to draw attention to the door when an alarm condition occurs. The
alarm output can also be connected to the alarm input of a CCTV camera, Digital Video Recorder,
Video Matrix or similar device to allow your CCTV system to react to the access breach.
The alarm output can be programmed to latch for the duration of the alarm condition or to pulse for
one second when the alarm first occurs.
