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 (Ref: ICC/ANSI A117.1-2009). 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 six (6) 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. Unobstructed Forward Reach. Where a clear floor or
ground space allows only a forward approach to an object
and is unobstructed, mounting height shall be a minimum
of 15 inches (381 mm), and a maximum of
48 inches (1.22 m), above the floor or
ground to the operable controls.

SECTION 1 - INSTALLATION
Prior to beginning the installation, we suggest that you become familiar with the instructions, illustrations, and wiring
guide-lines in this manual. This will help insure that your installation is performed in an efficient and professional manner.
Installation of the 2112 involves the installation of the hardware 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 2112
system to malfunction during operation.
When the 2112 is used to control a vehicular gate with an automatic gate operator, it must be mounted a minimum of
six (6) feet away from the gate and gate operator, or in such a way that a person cannot operate the 2112 system
and/or touch the gate or gate operator at the same time.
WARNING
Included with the system is an extra random keyed cabinet lock. If desired, for added security against unauthorized entry into the system,
the standard lock may be replaced with the random lock. Note: DoorKing cannot replace this specific lock or keys if lost.
1.1 Standard Internet Installation ONLY
See page 10 for 2112 Cat5 connection.
A Cat5 wire will need to be run to the 2112 installation location that is ALREADY connected to the internet, then installation can begin.

1.2 Optional Cellular Installation ONLY
T-Mobile
Cellular
Phone
Signal
Strength
An existing cellular phone will be needed to test the signal strength of DoorKing’s
cellular network in the desired installation location (a smart phone is preferred).
BEFORE the 2112 cellular module can be installed, the installation location MUST BE TESTED
for good cellular signal strength for reliable communication.
TEST this location using an existing active T-Mobile cellular phone ONLY.
DO NOT install the cellular module in a WEAK or NO signal area.
Activate the phone near the position where you want the cellular module to be installed. 3-4
bars of signal strength should be indicated on the phone for a reliable signal. If 3-4 bars are
not achievable in that specific location, then try moving the phone around and see if at least
3-4 bars can be achieved and maintained in a nearby location.
If a smart phone is being used, try using the browser to
connect to a website to verify good data transfer. Generally, the
higher the cellular module is mounted, the better the reception.
This also helps protect against vandalism. The cellular module
should be located as close as possible to minimize the wire
run. This allows less chance for lightning surges or other
electrical interference to disrupt the cellular signal. Keep the
cellular module away from any metal. This can also disrupt the
signal. After the 3-4 bar signal strength has been confirmed
(and the smart phone has good browser data transfer if used
for signal testing), the installation can begin.
Surface Mount: Cellular
module works inside plastic
enclosure. The cellular module
can be mounted outside the
enclosure if desired because
signal strength is a problem.
Avoid any metal around
module. DO NOT expose
module to weather.
Flush Mount: Cellular module needs
to be mounted outside metal
enclosure in a protected secure area
as high as possible for best reception.
Avoid any metal around module.
DO NOT expose module to weather.

2112 Surface Mount Configurations
Surface mount model can be mounted directly to a wall,
pilaster or post mounted using a DoorKing mounting post
(there are several different styles available). Be sure it is
securely mounted and is not subject to continuous vibration
from closing doors or gates.
Use existing 4 holes in cabinet box to
bolt the surface mount model on a
DoorKing mounting post. Use the
hardware that is supplied with the
mounting post.
Note: A gooseneck mounting
post anchored in concrete
does NOT make a good
ground.
Add washers on
bottom to angle the
unit upward (see Tip).
Mount on a Mounting Post

Note: Run ALL wires that
will be needed during the
cabinet installation, see
section 2.
IMPORTANT Choose how your
2112 will function (Internet or
Cellular connection, see
sections 1.1 and 1.2).
TIP: The mounting height of the 2112 will determine the
field-of-view of the video lens. High profile vehicles may
present a problem when viewing the person inside the vehicle
if the video lens is mounted too low. the unit can be mounted
at an upward angle to better view a person in a high profile
vehicle. Keep this in mind when you are determining the
mounting height of the unit.
WARNING! If this entry system is used to control a
vehicular gate with an automatic gate operator, the entry
system must be mounted a minimum of six (6) feet away
from the gate and gate operator, or in such a way that a
person cannot operate the entry system and touch the
gate or gate operator at the same time.
Use the 4 existing holes in the
cabinet box. Run conduit inside or
outside of wall or pilaster if desired.
Use appropriate hardware to mount
the cabinet (Not supplied).
Be sure that the mounting hardware
does not protrude into the cabinet
where it could cause a short.

2.3 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.
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.
