In many applications the switch contact connection is
between the alarm input pin and the chassis or signal ground.
In the QSP-660 the contact connection can be between either
the ground (alarm connector pin 15) or the +5V (alarm
connector pin 13). In some alarming devices this is not a
metallic switch contact but rather a solid state device that
grounds (Logic Low) the input as a normal condition or as an
alarm condition. The four activation modes are provided to
simplify connection to most alarm sources. (The factory default Alarm Activation Type is “Contact Closure”).

The QSP-660 alarm activation is defined as follows:
Contact Closure:
The alarm pin is connected to a current source (either +5V or ground).
Contact Open:
The alarm pin is not connected to any current source (unconnected pin).
Logic Low:
A logic “low” level less than 0.8V (ground) is present at the alarm pin.
Logic High:
A logic “high” level greater than 2.4V (+5V) is present at the alarm pin.
Alarm Log
The Alarm Log menu is used to view the current contents of
the internal Alarm Log and to clear the log or transmit the log
contents to the serial port for printing. The Alarm Log contains
the time, date, camera number, and type of alarm for each
alarm event that has been stored. It can store up to 100 alarm
events at which point new alarm events continue to be stored
and replace the oldest event in the buffer. An Overflow
message is displayed in the upper left corner of the Alarm
Log menu if more than 100 events have occurred indicating
older alarm events have been displaced. An alarm event is
generated when any enabled and valid scheduled External or
Video Loss alarm occurs. For more information see Alarm
Scheduling on page 13. The Alarm Log is a very useful tool
for reviewing the VCR recording allowing rapid location and
review of recorded video time periods of interest.

The Alarm Log may be printed on a serial interface printer that is connected to the QSP-660 Serial Port. The
log may also be sent to a host computer for storage or processing rather than a printer.
