The channel inputs can be used for request-to-exit (REX) buttons, door position sensors, or lock status sensors
Configure input functions using Accessia Installer app
The inputs should only be connected to isolated switch contacts – do not connect to a power supply
Use a shielded cable and connect the shield to earth using the labeled earth post inside the enclosure
For end-of-line monitoring, use 2.2 kOhm +/- 1% resistors at the switch (Figure 1)
Figure 1: DEOL monitored input
For optimum DEOL monitoring performance, keep the inputs isolated from each other. If it cannot be avoided, the two inputs on the same channel can share a common terminal. In this case, wire the two inputs as shown in Figure 2
Figure 2: DEOL monitored inputs with common terminal
Adjacent to the input terminals is a switchable 12VDC power output for peripheral devices. This can be used for a touch-free REX button or a door-left-open alarm. Configure its function in Accessia installer app
The labeling on the Hub shows the correct pin out for all these connections
