POWER CONNECTION STEPS
The LPH3100A switch supports dual +12 to
24 VDC power inputs and changes relay status
when the power fails.
1. Insert the positive and negative wires

2. Tighten the wire clamp screws to prevent
the DC wires from loosening.
3. Link a closed-loop device (such as an alarm
system) to P-Fail for transmit signals only,
