CONNECTING DEVICES TO ALARM INPUTS AND OUTPUTS
Appendix 2:
Connecting devices to alarm inputs and outputs.
NV-DVR5009 and NV-DVR5016 recorders have 9 or 16 alarm inputs and out allowing you to connect
external devices. Connectors to plug in cables are equipped with handy clamp terminals.
NOTE: Both alarm inputs and outputs are not protected against any results of atmospheric discharges.
The user has to make sure that the inputs are protected against discharges, which may damage the
inputs permanently.
Current load capacity of each alarm input cannot exceed 5mA for 12 V DC voltage and 30 mA for
5 V DC voltage. Directly to outputs you can connect e.g. LED (light-emitting diode) creating a circuit
(as presented on the chart below) for each output. If there is a need to connect devices which demand a
lot of current you have to use additional circuits (e.g. with a transmitter). Outputs can work as normally
closed or normally open.
