About This Guide
This Technical Guide is designed to provide general information for installing Keyscan access control systems.
This guide assumes the installer has knowledge of electrical, electronic, mechanical, and computer concepts,
as well as having familiarity with access control systems and associated components. The guide is divided into
4 sections:
•Installation Requirements
•Installation Guidelines
•Mounting and Connecting System Components
•Appendices
The technical guide has been organized in a manner that allows for quick referencing based on installation
tasks with pertinent diagrams.

Keyscan Technical Guide (PC109x - 04.12) 9
Installation Requirements
The following is a review of power, cable, and ground requirements for the access control system.
Power
Each access control unit requires two dedicated Class 2 transformers. The following transformers are
acceptable:
•16V 40VA transformer
•16.5V 37VA transformer
Do not mount the transformers inside the ACU metal enclosure.
Any deviation from a specified transformer or the use of a single transformer to power multiple access control
units will cause faulty system operation. All warranties are voided if non CLASS 2 transformers or incorrect
voltages are used.
Standby batteries with their duration times for access control and reader power are listed on page 19.
Important
The power supply included is for the exclusive use of the access control unit and the readers. Do not use it
to power external devices such as door strikes or magnetic locks.
Electrical Precautions
Be sure that all circuit breakers powering the system are switched off before commencing installation or
modifying wiring connections. Do not apply power before the installation is completed otherwise the equipment
may be damaged. Ensure all enclosures are connected to earth grounds for proper and safe system operation.
Tools
We recommend having the following tools on hand to install the access control system:
•Digital Voltmeter
•Wire Cutters & Needle Nose Pliers
•Soldering Iron & Tape
•Set of Screwdrivers
•Drill & Drill Bits
•Laptop Computer (optional)

Keyscan Technical Guide (PC109x - 04.12) 10
Cables
The following table outlines system cable requirements. Please be sure to review grounding guidelines for safe
system operation. Avoid running access control cables parallel with AC wires or across fluorescent light fixtures.
This can cause AC induction or transmission interference.

Grounding
Ground all access control units and shielded cables to a cold water pipe. For multiple access control units, all
shielding should be connected to a single point earth ground.
It is important to ground the shields of the readers and communication cables to a single point cold water pipe
at the access control unit. Failing to ground the shields or using incorrect cables may cause noise or
interference and result in improper card reads. Also, refer to Grounding Communication Cable Shield.
Important
It is extremely important that the chassis ground (GND) on the DPS-15 is connected to the metal
enclosure ground lug.

Keyscan Technical Guide (PC109x - 04.12) 14
General Installation
Guidelines
Mounting Access Control Units and Components
Identify and mount all hardware including access control units (ACUs) and power supplies in a convenient and
suitable location. Do not mount access control units close to high-voltage equipment. Comply with all local and
regional codes.
Each access control unit requires two dedicated Class 2 transformers. The following transformers are
acceptable:
•16V 40VA transformer
•16.5V 37VA transformer
Record the serial number and the model number listed on the control board. The serial number is a required
entry in the Keyscan Client software. Do not mount the transformers inside the ACU metal enclosure.
Mounting Readers and Door Hardware
Install all door hardware. Position readers at a convenient height on the door latch side. Using a battery for
power, ensure the door operates properly – alignment, holding, activation, de-activation – before connecting
to the Keyscan access control unit. Where applicable, comply with all fire and safety codes for the installation
of door strikes and magnetic locks.
If a door/reader is located beyond the maximum cable length to the ACU, use a Keyscan WIEEX2 Extender Kit
to a maximum distance of 4000 feet (1219.2 m).
Cables
Run all cables between components. Label cables as they are installed. Do not connect cables at the ACU until
testing all hardware for correct operation. Cable routes should avoid potential sources of electrical noise from
fluorescent light fixtures, high-voltage equipment, high-voltage lines, and radio transmission equipment that
may impede access control communication.
Use specified cables with the proper gauges. Do not exceed maximum cable distances.
Elevators
Elevator installations require licensed third party technicians. Not all readers are designed for elevator
operation. Use suitable readers.

Keyscan Technical Guide (PC109x - 04.12) 15
Terminate Wiring at the ACU
Terminate reader, lock, input, elevator floor, and elevator input wiring to the designated input terminals on the
appropriate door or elevator control boards or relay boards.
All Keyscan OCB-8 circuit board relays use Form C contacts with the following ratings:
•30VDC – 5 Amps
•24VAC – 10 Amps
Use a separate power supply for door locking devices. Do not use the DPS-15 power supply except for
powering the ACU circuit boards and readers.
Be sure to ground the shields of reader and communication cables to a single point cold water pipe ground at
the access control unit. Failing to ground the shields may cause incorrect card reads from noise or interference.
Jumpers
Keyscan factory defaults all control board jumper settings before they are shipped. However, Keyscan
recommends that you review the Jumper Settings section starting on page 53. You may have to reset jumpers
depending on the installation.
Communication
Communication must be established between the personal computers (PCs) with the Keyscan software and the
access control units. Communication is divided into 2 segments:
•Single ACU communication
•Multiple ACU communication
Test the communication ports on the PC(s) before connecting to the access control system.
Where a serial connection applies between the PC and the ACU and the span is greater than the maximum
allowable cable distance, use a Keyscan COMMex extender kit.
Power Up and Test Voltages
Be sure that all necessary power supplies have been installed. Use the DPS-15 power supply for powering the
ACU control boards and the readers only. Use the calculation tables in the Power-up and Test Voltages section
to estimate the current demand does not exceed the current rating of the DPS-15, otherwise you may require
an additional power supply.
A separate power supply must be used for door lock devices. Before applying power, verify all cable
connections are correct. Ensure no short circuits exist when measuring voltages. Verify DC polarity is correct
for all equipment.
Also, be sure to load the factory defaults immediately after the control board is initially powered up.
Power-up instructions and power calculation tables start on page 107.

Mounting – Enclosure &
Components
The following sub-sections review mounting metal enclosures, access control units, circuit boards, and power
supplies.
UL STD 294, CSA STD C22.2 (No. 205), CE, FCC 15
Subpart B
To be compliant with UL STD 294, CSA STD C22.2, CE, or FCC 15 Subpart B standards, please adhere to the
following practices:
•use the Keyscan metal enclosure with the CSA, CE, FCC label on the inside of the panel cover
•mount control boards with the standoffs supplied as instructed
•secure the enclosure cover with the 4 screws supplied
•connect the tamper switch to the TB3 terminal block on the control board
•use the Keyscan DPS-15 to power the control board and readers
•ensure 2 x 16V 40VA transformers or 2 x 16.5V 37VA transformers are connected to the Keyscan DPS-15
power supply
•locate the transformers within 30 feet (9.144 m) of the Keyscan DPS-15 power supply - do not mount the
transformers inside the ACU metal enclosure
•do not use the Keyscan DPS-15 power supply to power door strikes or auxiliary equipment
•use a standby battery with sufficient amp hours (minimum is 12V 7.0 Ah) connected to the Keyscan DPS-
15 power supply
•connect a proper ground wire from the ground lug inside the metal enclosure to a cold water pipe ground
(earth ground)
•connect the enclosure ground strap to the designated studs on the metal enclosure and the enclosure
cover
Any deviations or alterations will result in non-compliance of these standards.

Keyscan Technical Guide (PC109x - 04.12) 17
Mounting the Metal Enclosure
The metal enclosure has four (4) pre-drilled holes for mounting to the wall. Connect the ground lug to a true
earth ground. When locating mounting areas, ensure the metal enclosure is not close to high voltage
equipment and the cable lengths are within their maximum allowable distances.

Mounting the PC109x Control Board to Metal Standoffs
Use the eight (8) enclosed ¼” screws to secure the PC109x control board to the 3/8” metal standoffs mounted
inside the metal enclosure. Be sure to place the internal tooth star washers between the control board and the
screw as shown in Figure 4 – Mount and Fasten PC109x Control Board to 3/8" Male/Female Standoffs.
Important
Finger-tighten the ¼” screws with a screwdriver. Do not use a power screwdriver or apply excessive force
when tightening screws to the metal standoffs when mounting control boards. Ensure that the control
board does not have power when mounting otherwise it may be damaged from a potential short-circuit.
Rev 11, Rev 10 & Rev 9 Control Boards
If installing a Rev.11, Rev.10, or Rev. 9 control board in a metal enclosure with the pre-mounted metal
standoffs, you require an adaptor kit - P/N – AK2005.
