Choose the mounting location for the unit. Remove the back panel from

the unit by pulling the top of the panel out of the unit. Mount the panel

to a solid surface or post (hardware not provided) with the top of the

panel up.

IMPORTANT NOTE: Both the back panel and TAC1 unit must be oriented

and mounted in the upright position as shown at right and on the

installation warning label. Failure to correctly mount the panel and unit

may cause damage to the board during installation.

be between 48 and 53 Vdc.

• Never run data wires and high voltage wires in the same

conduit. The high voltage wires may interfere with the data

wires and cause the system to malfunction.

• Reversed polarity will not damage the unit, however, some

telephones will not function properly.

Home Phone

Many phone companies have updated their color standards due to

the use of Cat 5 cable for most phone line installs, and keep

residential and business installs in line with each other. In the new

standard, there is no green, red, black or yellow wires, they have

been replaced by white/blue, blue/white, white/orange, and

orange/white. If the wire is primarily orange with white stripes

then that color is orange/white. Refer to the table below. The NID

labels will most likely have the old coloring scheme on them, and

most telephone wiring components you can purchase will still

reflect the original colors.

NOTE: If the unit will be connected with an

alarm system, you must connect the telephone

line to the alarm system first in the series from

the Telco box. If the units are not connected in

this order, they will not operate properly.

Notes about wire connectors

(terminal blocks):

• Wire connectors can be

removed to simplify wiring.

• DO NOT overload wire

connectors. Use ONLY one

wire per hole.

Ensure that the unit is grounded properly. The unit contains a

number of static sensitive components that can be damaged by

static discharge.

To AVOID damaging gas, power or other underground utility

lines, contact underground utility locating companies BEFORE

digging.

NOTES:

• Use a minimum of 12 gauge wire in most cases. The type and

length of the earth ground rods vary by region. Contact the

building inspector’s office in the municipality where you plan to

install the unit for correct grounding materials and installation

procedures.

• Do not ground the unit to a pedestal post (gooseneck) if one is

used.

NOTE: Chamberlain is not responsible for conflicts between the information listed in the above table and the requirements of local building

codes. The information is for suggested use only. Check local building codes before installation.

POWER WIRING

The 110 Vac outlet must be dedicated to the unit only. This outlet

should be wired back to its own 10 Amp minimum circuit

breaker. This will prevent two problems:

• Other equipment cannot introduce spikes, noise, surges, or

dips into the power circuit.

• The system’s operation will not be affected if any other

equipment develops a short circuit across the power line.

Connect the transformer into a 110 Vac outlet after all

connections have been made, any other type of outlet will cause

damage to the system.
