2.3.3 Wiring the Circuit
2.3.3.1 Devices Less than 1A at 30 VDC
If the power for the device is less than 1A at 30 VDC and is not an inductive load, then see
for the wiring diagram.
When configuring with an inductive load, please use an intermediary relay with a High PIV Ultrafast
Switching Diode. We recommend using the Network Dual Door Strike Relay (CD# 011375) (see
Section 2.3.3.2, "Network Dual Door Strike Relay Wiring Diagram with External Power Source"
).
