3.7.4 Alarm Input and Relay Output
The DVR offers 16 alarm inputs for external signaling devices, such as door contacts
or motion detectors. Each alarm input can normally open or normally close. Once
configured, an alarm input can invoke many different activities, including triggering a
relay device, sending an alert to a security office or store pre-alarm video to the DVR.
3.7.5 Alarm Input
For this series DVR, a grounding signal is needed for alarm input.
If you need to connect two units or one DVR and other device, use a relay to
separate them. Please refer to Figure 3-6 for more information.

3.7.6 Alarm Output
Do not connect alarm output ports directly with high power loads (no more than 1 A).
You can use the co-contactor to realize the connection between the alarm output port
and the load. Refer to Figure 3-7 for more information.
