Magnetic locks or electric strikes must be
powered from a separate UL Listed power
transformer.
DO NOT
power strikes or magnetic
locks from the unit’s power transformer. Use
minimum 18 AWG wire for runs up to 100 feet;
16 AWG wire for runs up to 200 feet. It is
recommended to keep power wire runs as short
as possible.
Optional Phone Line Surge Suppressor
DoorKing Surge Suppressor
P/N 1877-010 (or equivalent) is optional but
highly recommended.
For best protection, surge suppressor ground
wire
MUST
be 3-ft. or less in length. Use
minimum 12 AWG wire.
Refer to instruction
sheet included with surge board and section
1.5 for complete information.
Optional Low Voltage Surge Suppressor
DoorKing Surge Suppressor P/N 1878-010 (or
equivalent) is optional but highly recommended.
For best protection, surge suppressor ground wire
MUST
be 3-ft. or less in length. Use minimum 12 AWG
wire.
Refer to instruction sheet included with surge
board for complete information.

Connect to Incoming Telephone Company’s
Phone
Line
Locate the telephone company demarcation device.
IMPORTANT
Identify the telephone line that will connect to the Access Plus
unit and wire as shown.
Use only twisted pair telephone wire that is rated for direct underground
burial.
DO NOT
use wire that is intended for indoor applications.
Recommend Cat5e Gel Filled (flooded) UV Resistant Direct Burial Cable in
conduit.
DO NOT
run telephone wires and high voltage wires in the same
conduit. For complete info,
see section 1.6.
Check Polarity of Telephone Line
Check for polarity on the phone “IN” wires, terminals 1 and
2. Terminal 2 must be positive with respect to terminal 1. Set
a VOM meter to measure DC volts. Place the positive lead on
terminal 2 and the negative lead on terminal 1. If the meter
shows a positive voltage - OK. If the meter shows a negative
voltage (needle moves off scale to the left), reverse the wires
on terminals 1 and 2.
