Power Failure Unit
Guidelines
• Up to four SLTs can be connected to the Power Failure Unit (VA-43703).
If a power failure occurs, the SLTs will automatically receive dial tone
directly from the central office. DBS features and restrictions do not apply
when the SLTs are receiving dial tone from the CO.
• If a call is in progress through the Power Failure Unit (PFU) when the
power is restored, the call will be disconnected.
• The following tools are required to install the PFU:
- Phillips
screwdriver
- Needle-nose
pliers
- Diagonal
shears.
Installation
1. Remove the cover from the Power Failure Unit (PFU).
2. Remove the cable punch-out plate (Figure 5-12) to make an opening for
the cables coming into the PFU.
To remove the plate, cut the grooves on either side with diagonal shears.
Then bend the plate back and forth with needle-nose pliers to remove it.
