the input goes back to normal. If you choose Total you will receive a fixed number of snapshots
once the alarm is detected. You can also select the time between snapshots in the Snapshot Interval
field, and you can choose the maximum number of Snapshots Sent per E-mail. Camera snapshots
will not work if a User Login is required in the camera.
Note: the E-mail messages sent via Alarm Response operate independent of Profile Class and
Contact Schedule.
High Sound Alarms
The IMS-4000 measures the sound level with the built-in microphone on the front panel. This can
be useful in detecting audible alarms in close proximity to the unit. To detect alarms at a distance
from the unit, you can plug an external condenser microphone into the mic jack. Note that the
audible alarm must be more than just a periodic beep. Only alarms that produce a loud, steady or
pulsing signal (for example, smoke detector alarms) will be recognized by the IMS-4000.
The unit is programmed to trip an alarm if the sound level increases by a programmed number of
decibels. On the High Sound programming screen this parameter is listed as "Change in dB." The
default setting is 30db. This means that if the audio level increases more than 30 dB for the dura-
tion of the recognition time, an alarm will be tripped.
To verify that your audible alarm is capable of tripping an alarm we recommend that you perform
several tests to check the decibel increase at the IMS unit. The test should involve tripping your
audible alarm and checking the measured level within the ConsoleView Software. Using the data
obtained from your testing, you can then set the Change in db parameter appropriately.
If you are not concerned about High Sound alarms or if the unit is installed in a generally noisy
environment that could easily trip false alarms, we recommend you disable the High Sound alarm
monitoring via the Schedule.
Realtime Strip Chart
A realtime Strip Chart will show continuous values for sensors which provide an analog value. Just
click on the sensor name and the chart will appear.
The high and low scale of the chart is based on the Min and Max values. To reset Min/Max values,
click on the Reset button to the right of the chart.
