9. Alarm instructions
CAM1 and CAM2 each have an alarm input. If an ALM and GND cables are shorted together,
its NO-alarm will activate. The Indoor monitor will continue to ring for 120 seconds until
button is pressed. The monitor will then return to Standby mode.
For models with installed MicroSD card, an alarm will also trigger a snapshot or video
recording (depending on which setting is selected). The recording time is 120 seconds,
or until
button is pressed. The monitor will then return to Standby mode.
Connection diagram:
There is an alarm input for each of the two camera channels. Each alarm input can be
configured to accept either a Normally Closed (NC) or Normally Open (NO) alarm inputs;
or be Disabled.
A NO-alarm input will trigger an alarm event when the ALM & GND cables are shorted
together. Conversely, a NC-alarm will trigger an alarm event when the ALM & GND cables
are disconnected (open circuit).
