2.6 Sensor and Relay pinhole allocation on NX8000 series
i
NXU8000 series needs to purchase the E-I/O box for I/O connection.
The signal from the sensor (i.e., infrared sensors, smoke detectors, proximity sensors, door sensors,
etc.) is being transmitted to the I/O card, and this triggers the system to respond and send signal to
relay device (i.e., alarm, telephone etc).
