Cable Specifications
The following table outlines system cable specifications. 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.

Keyscan Inc. –Technical Guide (PC109x - 07.15)
13
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.
Grounding Communication Cable Shield
When terminating the communication cable in the metal enclosure, insulate the shield and connect it to the
ground lug. Keyscan suggests Alpha PVC 10516 –16 AWG clear tubing or a comparable tubing to insulate the
shield. Do not connect the shield to GND on a communication terminal block.
Note
Keep all shield wires and cables away from the control board.

Mount the Enclosure & Circuit
Boards
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, 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 - 07.15)
16
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.
Figure 2 –Mounting the Metal Enclosure
Ground Lugs
The metal enclosure includes one ground lug pre-mounted near the top and one spare ground lug, which
mounts on one of the available ground lug studs. You can also re-locate the pre-mounted ground lug to
minimize the length of shield used.

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 one (1) Ampere with 200mA in reserve for
accommodating peak current operating demands. See page 120 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 backup
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. Use of non-compliant transformers or deviation from the use of
two (2) approved transformers per access control unit or incorrect voltages void all Keyscan warranties. The
system may operate erratically if the voltage is lower than 12 VDC.
Mount the DPS-15 power supply as shown on page 21. For power supply connections, refer to Figure 85 on
page 124.
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.
