Owner's Instructions:
The Garage Door Opener Surge Protector is designed to protect garage door
openers against damage from lightning and power surges. The Surge Protector
will stop radiated surge currents from coming through wall control and saftey
sensor wires, as well as surge currents from coming through AC power line
according to the rating chart shown below.
Plug the Surge Protector into grounded (3-wire) 120V AC outlet within four (4)
feet of the garage door opener. Plugging Surge Protector into a GFCI (Ground
Fault Circuit Interrupter) is acceptable, but not recommended as power surges
may cause the GFCI to trip and you will need to reset the outlet in order to oper-
ate the garage door opener.

Before you begin:
protector, use the 5’ piece of white-white/black 24
AWG bell wire (included) as EXTENSION from
surge protector to opener.
• Note polarity/wire colors, twist original wire with
extension wire together, and insert into surge
protector. The terminals colored white and gray on
the surge protector are designated for the IR
sensor wires.
Follow these steps:
It is recommended that you label wires prior to
removing them from the garage door opener. Label
safety sensor wires and wall control wires using
color codes if applicable.
1. Unplug Surge Protector and garage door opener
from AC outlet.
2.Verify that the safety sensor wires are connected
to the gray and white terminals on the Surge
Protector. If not, re-wire Surge Protector
following above instructions.
3. If connected to the gray and white terminals and
LED's are still not illuminated, disconnect the
twisted wires from both gray and white terminals
and switch positions. Ensure they are making a
good connection within the terminals of the Surge
Protector.

Installing the wall control wires:
• At the garage door opener, remove the wall control
wires from opener terminals, noting polarity and/or
wire color positions.
• Since these wires will now be routed to the surge
protector, use the 5’ piece of white-white/red 24
AWG bell wire (included) as EXTENSION from
surge protector to opener.
• Note polarity/wire colors, twist original wire with
extension wire together, and insert into surge
protector. The terminals colored red and white on
the surge protector are designated for the doorbell
button/wall control wires.
• Attach wires to opener terminals in same order/
color combination as original installation. (Consult

power and is protecting your garage door opener
system. If the indicator light goes out, the surge
protector has sacrificed (depleted) itself to protect
the garage door opener system and should be
replaced immediately.

directly into the power source and must not be “daisy-
chained” together in serial fashion with other power
strips, UPS, other surge protectors or extension cords.

and tear, erosion, depletion, obsolescence, abuse,
damage due to low voltage disturbances (i. e.
brownouts or sags), non-authorized program or system
equipment modification or alteration. This warranty is
secondary to any existing coverage of any Connected
Equipment, including, but not limited to, any manufac-
turer’s warranty, extended warranties or insurance cov-
