1. If the clear floor space allows only forward approach to the system, the maximum high forward reach allowed is
48inches above grade to the top of the keypad.
2. If the high forward reach to the system is over an obstruction of greater than 20 inches but less than 25 inches,
the maximum high forward reach allowed is 44 inches above grade to the top of the keypad.
3. If the clear floor space allows parallel approach by a person in a wheelchair, the maximum high side reach shall
be 54 inches above grade to the top of the keypad.
4. If the high side reach is over an obstruction of 24 inches or less, the maximum high side reach allowed is 46
inches above grade to the top of the keypad.
•Prior to beginning the installation of the telephone entry system, we suggest that you become familiar with the
instructions, illustrations, and wiring guidelines in this manual. This will help insure that you installation is performed in
an efficient and professional manner.
•The proper installation of the telephone entry panel is an extremely important and integral part of the overall access
control system. Check all local building ordinances and building codes prior to installing this system. Be sure your
installation is in compliance with local codes.
•When used to control a door or pedestrian gate, try to locate the telephone entry system as near as possible to the entry
point. The unit should be mounted on a rigid wall to prevent excessive shock and vibration from closing doors or gates.
Continuous vibration and shock from slamming doors or spring-loaded pedestrian gates will damage the circuit board.
Under no circumstances should the unit be mounted directly to a moving door or gate.
• ADA mounting requirements for door control. The requirements below apply only when the telephone entry system is
being used to control entry through a public door only. If this system is used to control entry through a vehicular gate or
private entrance, the dimensions noted below do not apply.
•When used to control a vehicular gate with an automatic gate operator, the telephone entry system must be
mounted a minimum of ten (10) feet away from the gate and gate operator, or in such a way that a person cannot
operate the entry system and/or touch the gate or gate operator at the same time.
•Be sure that the system is installed so that it is not directly in the traffic lane. Goose neck mounting post and kiosks
work well for these type systems. When planning where to locate the system, take into consideration traffic lane layouts,
turn around lanes for rejected access, conduit runs, power availability, etc.
•Environmental factors must also be taken into account. Surface mount units are designed for direct outdoor
installations, however it is preferable to protect them from direct exposure to driven rain or snow whenever possible.
Flush mount units must be protected from direct exposure to the elements.
•This telephone entry system contains a number of static sensitive components that can be damaged or destroyed by
static discharges during installation or use. Discharge any static prior to removing the circuit board from the lobby panel
by touching a proper ground device.
•Instruct the end user to read and follow these instructions. Instruct the end user to never let children play with or
operate any access control device. This Owner’s Manual is the property of the end user and must be left with them
when installation is complete.

1.4 16.5 VAC Power Wiring ONLY!
The 1838operates ONLY on 16.5 VAC. DO NOT power the unit with 24 volt AC power. Use the supplied power transformer, 16
VAC, 20 VA (or U.L. listed equivalent) to power the system. DO NOT power any other devices (electric strikes, magnetic
locks, etc.) from the unit’s power transformer. See table below for wire run distances.
Power Interruption Note: The Time
and Date calendar chip (Section 2,
2.7.1) in the 1838will keep time for
approximately 48hours if power to
the system is lost or removed. If
power is off longer than this, the
Time and Date will need to be
reprogrammed into the system. All
other specific programming that has
been done will remain intact after
power has been restored.
DoorKing offers a 12 volt .8 amp
hour gel cell battery that can

CAUTION
DO NOT power the unit from a 24-Volt
source (Such as a gate operator).
Damage will occur to the unit that is
NOT covered under DoorKing’s warranty.
Proper Grounding and the use of surge suppressors can significantly reduce the chance of component failure because of static
charges or surges. To be effective, ground connections should be made with a minimum 12 AWG wire to a ground point within
10 feet of the device being protected. The ground point can be at an electrical panel, a metallic cold water pipe that runs in the
earth or a grounding rod driven at least 10 feet into the soil. A gooseneck mounting post anchored in concrete does NOT make
a good ground.
Telephone Line Surge Suppressor
It is highly recommended that telephone line surge
suppressor (DoorKing P/N 1877-010) be installed
to help protect the system from phone line power
surges. Surge suppressor must be positioned 3 ft
or less from the ground source, 12 AWG min.
Low Voltage Surge Suppressor
It is highly recommended that a low voltage surge
suppressor (DoorKing P/N 1878-010) be installed to
help protect the telephone entry system from power
surges. Surge suppressor must be positioned 3 ft or
less from the ground source, 12 AWG min.

“Tip” and “Ring” Definition. Common terms in the telephone service industry referring to the two wires or sides of
an ordinary telephone line. Tip is the ground side (positive) and Ring is the battery (negative) side of a phone circuit. The
ground side is common with the central office of the telephone company (telco); the battery side carries -48volts of DC voltage
when in an “Idle” or “On Hook” state.

Dialing) trunks, T-1 lines, and ground start lines where the field side (“terminal”) equipment (a company's PBX switch, for
example) can only function correctly with correct tip and ring polarity.
Wire Type. It is extremely important to use the correct type of wire in telephone applications. Since the Access Plus system
requires phone lines to be run outdoors or in an underground environment, we recommend that you use only wire that is
rated for direct underground burial. For example, use Cat5e Gel Filled (flooded) UV Resistant Direct Burial Cable run in
conduit for your Access Plus system phone line requirements. Do not use thinly insulated brown-jacketed telephone wire (the
type found in the walls of a structure) for outdoor or underground phone line wiring. Using improper wire can cause noise and
hum on the phone line. Be sure that phone wire pairs are twisted.
Wire Size and Distance. Phone lines can be run up to 3600 feet, provided that the proper wire size is used.
1.6 “OPTIONAL” Telephone Line Wire
Be sure to observe electrical safety when working with phone lines. Phone lines carry electricity and the ring voltage can deliver
a substantial jolt.
In most older residences and buildings, the phone cable contains four wires; green, red, black, yellow. The green and red are
twisted to make one pair and the black and yellow are twisted to make another pair (This allowed for the addition of a second
phone line since telephones use only two wires). Most phone lines installed in the U.S. in the second half of the 20th Century
have this type of wire. This type of wire is now obsolete. All new telephone projects are using Cat5 wire. If you have Cat5 wiring
in your residence, the conversion is simple:
The convention for Cat5 wire is as follows:
•Colored pairs match; e.g., WHITE/blue mark (Tip +) wire goes
with BLUE/white mark (Ring -) wire for one phone line, etc.
•The pairs are used in the order pictured: for the first line, you
use BLUE, for the second line you use ORANGE, etc.
•An easy way to remember this is that the colors run from the
sky to the earth. BLUE sky comes first; ORANGE sunset second;
GREEN grass third; BROWN earth last.

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.

The wires connecting terminals 1 & 2 from
the 1838to terminals 7 & 8on the
DoorKing RS-485 boards MUST be
twisted. We recommend that you use
Cat5e cable for all the RS-485 connec-
tions (See section 1.6 for wire size and
run distances table). Use one twisted pair
to connect these terminals (terminal 1
connects to RS-485 terminal 8; terminal 2
connects to RS-485 terminal 7) and then
one wire from another twisted pair to
connect the common terminal (terminal 3
from the 1838to terminal 6 on the RS-485
board).
If wiring will be
outdoors or under-
ground, use Cat5e
Gel Filled (flooded)
UV Resistant Direct
Burial Cable.
Any RS-485 Keypad, Cardreader and
MicroPlus RF Receiver sequence
allowed. Maximum distance from end
to end is 4000 feet in a Daisy Chain
format as shown, see next page for
different RS-485 wiring configurations.
Do Not power RS-485 devices from the 1838.
RS-485 devices must be powered from their

Receiver and Access
Plus system “Daisy
Chain” wiring
sequence allowed.
Access Plus system on
end of “Daisy Chain”
wiring sequence has the
strongest signal strength.
The Access Plus system can be wired in the middle of the “Daisy Chain” if needed. It is
important that the distance restriction (4000 ft) be observed and that the devices at the end
of the chain have their termination switches ON. The devices in the middle of the chain have
their termination switches turned OFF.
Every RS-485 device (keypad, card reader, MicroPlus RF
receiver) must have a unique address assigned to it, starting
with 003. The address selector switches are located on the
RS-485 circuit board (see instruction sheets that come with
each RS-485 device). The address order of the devices
connected to the 1838does not matter. What is important is
that the addresses must be numbered in sequence. Do not
skip a number in the address sequence and start the
sequence with 003
(e.g. If three (3) RS-485 devices are daisy chain wired to the
1838and their addresses are 003, 004 and 006, this is wrong.
They must be addressed 003, 004 and 005).
The 2 internal relays on the 1838circuit board are 001 and
002. Valid RS-485 external device addresses for use with
the 1838 are 003, 004, 005, 006, 007 and 008.
Important Note: The device address is referred to as a
“Relay Number” in the programming software.
A termination switch is located on every circuit board. The
termination switch must be OFF for every device wired in
the middle of the daisy chain. The devices at each end of
the daisy chain must have their termination switches ON.
Some Configuration Problems to Avoid:
The total distance for the complete wire run is greater than
4000 ft.
There are more than 6 RS-485 devices.
There are more than 2 wire runs coming out of the 1838.
There are more than 2 end devices
terminated and/or incorrect end device
terminations (Not turned ON).
There are more than 6 addresses and/or
duplicate or skipped addresses.
An RS-485 device can not have 2 RS-485
devices separately continued from it.
The 1838must have it’s SW2 termination
switch turned OFF when 2 terminated end
devices are being used.
