the ground (alarm connector pin 15) or the +5V (alarm			DISPLAY: Accept and Return
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.

The Alarm Log can be cleared by pressing the ZOOM button.
