(c)
When the alarm device is shared with two NVRs or connected to a
NVR and other devices, it should be isolated by relays.
2.
Alarm OUT
The alarm output of the NVR can not be connected with high-power
load (no more than 1A). In the output circuit, be careful about the
excessive current that may cause damage to the relay. When using
high-power load, extra relays are needed.
