CONNECTING SENSORS TO THE HVR
Each HVR unit may have up to 16 Sensor inputs. These inputs can be used with devices such as infrared devices, motion device,
glass breakage alarms, door and window trips, and many more. The Sensors can be set to Normally Open or Normally Closed inside
the software.
There are 4 Common Grounds (-) and 16 sensor inputs (+). There is no power supplied to the ports so an external power supply must
be used if power is necessary.
