CONNECTING DEVICES TO ALARM INPUTS AND OUTPUTS
NV-DVR3009 and NV-DVR3016 have 4 alarm outputs that can trigger external devices. Connectors to
connect cords have easy-to-use screw terminal that can be taken out. Grounding (G) is the first pin to
the left. Alarm inputs are next.
Electric load capacity of each output cannot exceed 100mA. You can connect light emitting diode
(LED) to outputs creating circuit as on the scheme. If it necessary to connect devices that require a lot
of power supply you need to use additional circuits with i.e. relay.
Attention: Both alarm inputs and outputs are not protected against atmospheric discharges.
Users should protect inputs from the discharges as they can permanently damage
them.
