1812-162-G-12-10

General Information

• 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.

1. If the clear floor space allows only forward approach to the system, the maximum high forward reach allowed is
48 inches 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.

• 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.

SECTION 1 - INSTALLATION

Installation of the 1812 Access Plus Telephone Entry System involves the installation of the hardware, by-pass board, and the
wiring of these components. Be sure that all dirt, metal or wood debris is removed from inside after mounting it. Any debris
inside could damage the control board and cause the 1812 Access Plus system to malfunction during operation.

When the 1812 Access Plus is used to control a vehicular gate with an automatic gate operator, it 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 1812 Access Plus system and/or touch the gate or gate operator at the same time.

The 1812’s by-pass board provides a method to by-pass the 1812 and route the incoming telephone line directly to the
homeowner’s phone. The By-Pass board IS NOT optional when using an incoming telephone line or internet (Telephone

Mode) – it must be installed as part of the 1812 system. All telephone wires for the 1812 must pass through the by-pass
board. Wire the by-pass board either for a “Single 1812 - telephone mode” pages 14 - 15 or “Multiple 1812s - telephone mode”

page 16.
Mount the by-pass board in a location that is easily accessible by the homeowner. In case of 1812 trouble or maintenance, the
homeowner will use the by-pass switch on the board to route the incoming telephone line directly to their home phone. If the
by-pass board is installed outdoors, it must be installed in a NEMA Type 4 enclosure (not supplied) to protect the board from
direct exposure to landscape sprinklers, rain, snow and other elements.

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. It is recommended
to run all necessary wires to the by-pass board in a “dedicated” telephone wire

for outdoor use to provide a degree of protection to personnel against incidental contact

with the enclosed equipment: to provide a degree of protection against falling dirt, rain, sleet,

snow, windblown dust, splashing water, and that will be undamaged by the external formation of ice

on the enclosure.

1.3 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. The best policy is to disconnect the house phone from the phone company Network Interface Device (also
known as ‘Demarcation Device’) before working on the wiring.

In most residential homes, 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 home,
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.

“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 -48 volts of DC voltage
when in an “Idle” or “On Hook” state.

Phone Line Polarity. Tip and ring reversal is mostly immaterial, except for special circuits including DID (Direct Inward

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 1812 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 1812 phone line requirements. Do not use thinly insulated brown-jacketed telephone wire (the type found in the walls of a

house) 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.

and Date calendar chip (Section 2,

2.7.1) in the 1812 Access Plus will
keep time for approximately 48 hours
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
connect to the main terminals 9 and
10 to provide back-up power during
power interruptions.
(DoorKing P/N 1801-008)

1.5 Grounding and Surge Suppression

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.

the new twisted-pair wire to CENTRAL OFFICE terminals
#1 and #2 on the by-pass board (Unless using a surge
suppressor, then wire to surge board first).

Place the by-pass switch in the “By-Pass” position until
the 1812 installation is complete. Test the homeowner’s
telephone. It should have a dial tone while the switch is
in the “By-Pass” position. See page 11.

Check Polarity of
Telephone Line

Check for polarity on the
incoming telephone line to each
board and maintain polarity
throughout the telephone line.
One potential problem checked
when a malfunction occurs in a
telephone entry system is to
see if the telephone line has
been wired to each board with
the correct polarity.

Test Example: By-pass board’s
CENTRAL OFFICE terminals #1
and #2. Terminal #2 must be
positive (Tip +) with respect to
terminal #1 (Ring -). 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.
