About This Guide
This technical guide outlines general information for installing Keyscan access control systems. The 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.

Keyscan Inc. –Technical Guide (PC109x - 04.15)
12
Installation Requirements
The following reviews power, tools, cables, 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 voided if non-compliant transformers or incorrect
voltages are used.
Standby batteries with their duration times for access control and reader power are listed on page 20.
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 Inc. –Technical Guide (PC109x - 04.15)
13
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
shields 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.
Important
Ensure the chassis ground (GND) on the DPS-15 is connected to the metal enclosure ground lug.

Mount the Enclosure &
Components
The following sub-sections review mounting metal enclosures, control boards, communication boards, output
control 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 Inc. –Technical Guide (PC109x - 04.15)

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.
For knockout and mounting hole locations/dimensions, see the diagram on the next page.

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 the internal tooth star washers are placed 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
tightening screws into the metal standoffs when mounting control boards. Ensure the control board is
disconnected from the power when mounting; otherwise, the control board 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.

Mounting the DPS-15 Power Supply
The Keyscan DPS-15 is a 13.5 VDC dual linear regulated power supply for powering the ACU circuit boards and
the readers with the following outputs:
ACU output 12 VDC @ 1.2 Amperes
AUX/RDR output 12 VDC @ 1.2 Amperes
Maximum Current Draw
The total current draw on each output should not exceed 1 Amp with 200mA in reserve for accommodating
peak current operating demands. Refer to DPS-15 Dual Power Supply –Current Calculation on page 80 and
use the calculation tables to determine the total current demand of the all the devices connected to the DPS-
15.
CSA/UL Approved Transformers
The DPS-15 power supply requires either of the following class 2 CSA/UL approved transformers and a standby
battery with sufficient amp hours.
2 x 16 V 40 VA
2 x 16.5 V 37 VA
The purpose of two transformers is to comply with UL STD 294, CSA STD C22.2, and charge the battery
circuit. The transformers must be located within 30 feet of the Keyscan power supply. Do not mount the
transformers inside the ACU metal enclosure. All warranties are voided if non-compliant transformers or
incorrect voltages are used. The system may operate erratically if the voltage is lower than 12 VDC.
Power supplies are mounted as shown on page 21. For power supply connections refer to Figure 54 on page
83.
Important
Do not use the DPS-15 to power door strikes or auxiliary equipment.
Backup Batteries
Select a battery with enough amp hours to operate the system for the total hours specified. The following table
lists power duration times:

Plastic Stand Offs
Plastic stand offs are pre-mounted on most power supplies, relay and communication boards. In cases where
stand offs are not pre-mounted, insert the double pronged end of the stand off in the metal enclosure hole
first. Then mount the circuit board to the stand offs.
