Voltage Calculation
Most remote power supplies require a minimum of 12V and a maximum
of 18V to run (AC or DC). The remote power supply is rated at a 12VDC
output at the stated amperage. Multiple power supplies may be required
to compensate for voltage drop over extremely long runs of wire or runs
with multiple remotes. Be sure that there is a minimum of 12V at each
remote. The following table shows the resistance per foot of wire for the
cable that we sell. If you are using another manufacturer’s wire, refer to
the specifications provided by that manufacturer. We strongly recommend
that you do NOT use wire gauges smaller than 18 AWG for power or data
when installing our gate system. Larger gauges are acceptable (16, 14,
12, and 10). For documentation on calculating voltage drops, visit our web
site at www.ptiaccess.com.

Battery Backup Calculation
Battery backup time is equal to the current draw (amps) multiplied by the
amp hour rating of the battery. For example: if the system draws 2 amps
and the battery is rated at 4 amp hours; the battery backup should last
for 8 hours if the battery is fully charged and all other conditions are right
(2 x 4 = 8). Certain external issues can influence this length of time, such
as the age and condition of the battery, damage to the battery or power
supply, power surges, and/or the level of charge in the battery. Also, each
time the remote is used while the AC power is out reduces the total backup
time as the current draw increases slightly when the keypad is in use. For
the battery backup function to be effective, the gate or door strike must
also have a separately powered battery backup.
Troubleshooting With LED Diagnostics
There are two light emitting diodes (LEDs) on the power supply circuit
board that can be used for troubleshooting. The red LED indicates DC
power and the green LED indicates AC power.

Amperage Calculation
INTRODUCTION
Use the chart below to verify that you have enough amps to support the
number of remote units to be installed. Do NOT exceed the 75% load for
the power supply. It is always better to have a higher amp power supply
than required as electronics will only pull the current that they need. Do not
confuse amperage with voltage, which must not exceed the specifications.
If you need assistance calculating your power needs, please contact
technical support.
The Remote Power Supply converts 120 VAC power to 12VDC and is
equipped with battery backup. The remote power supply comes in five
sizes (1, 2, 4, 6, and 10 amp) based on the amperage needed to support
the system. The power supplies also have a red reset button on the front
which allows you to interrupt the power and battery backup to reset the
entire system for troubleshooting purposes. Multiple power supplies can
be used to fit the needs of the particular setup.

Example:
1A power supply (900 mA max load) can support three keypads equaling 900 mA OR one
keypad and one 8-channel relay board totaling 800 mA. If you wanted to add any other
remotes in either case, you would have to move to the next larger power supply OR add an
additional 1A power supply. You would need a minimum of a 2A power supply to support two
8-channel relay boards (total 1000 mA). If you are unsure, always use the next size larger
remote power supply. It is always better to have more available amps than less as a remote
will only draw to its capacity and no more.
* Do NOT exceed 75% of load. This provides a safety zone to allow for most power spikes/
surges without locking up or damaging the system.
** When powering other equipment such as door strikes, HID readers, maglocks, or sirens
from a Wiegand, be sure to consider the current draw of that equipment.

Disclaimers and Warnings
We strongly recommend that installation and setup of Chamberlain
Access Solutions equipment be done by a certified, licensed, qualified,
and competent person. Chamberlain Access Solutions can recommend
local dealers and installers, but it is up to the customer to verify their
qualifications and negotiate any pricing or contracts unless Chamberlain
Access Solutions has been specifically contracted in writing to do so for the
customer. With any computer setup or installation, some troubleshooting and
adjustment of the configuration may be required. This will differ with every
installation and computer setup depending on operating system, software
installed, quality of components, internet connection, modem connection,
and any site-specific variables. Troubleshooting and configuration may
require purchasing additional equipment. Under no circumstances
will Chamberlain Access Solutions be responsible for any damages
either incidental or consequential based on these recommendations. All
installation of electronics and electrical systems must be in compliance with
local, municipal, and state codes, and the National Electrical Code.
Incorrect installation of electrical components can result in damage
to electronics as well as personal injury.
Cross-wiring the AC power with DC power will damage the
electronics.
Cross-wiring the positive and negative on the DC part of the
system will damage the electronics.
Connecting 120VAC directly to the power supply circuit board
bypassing the transformer will damage the electronics.

INSTALLATION INSTRUCTIONS
The following are instructions for installing a Remote Power Supply to
provide power for remote access devices. Please read this entire document
before proceeding and follow the steps in order. Refer to the diagram on
page 4 to reference the steps. If you need assistance or have questions
about this installation, please contact technical support at (888) 528-7826
or support@ptiaccess.com.
1. Mount the power supply case on the wall with solid anchoring
devices. The power supply battery and circuit board should be
left in the case as manufactured and not removed or installed
separately. Power supply cases are not weatherproof and should
be installed indoors. All power supplies for a site should be
installed together, centrally located in the office or a maintenance
room that will be accessible for future maintenance or service.
Each power supply should be clearly labeled inside the cover
to show which remotes are powered from it. If multiple power
supplies are being installed, refer to the Multiple Power Supply
Installation Guide available on our web site. Never power cameras,
door strikes, or sirens from the same power supply as remote
keypads and multiplexers as these items can cause power spikes,
underpowering the other remotes. Power supplies should be
installed near a 120 V wall outlet.
2. Feed the transformer cable through one of the four knockouts on
the sides of the power supply case using the correct bushing.
On 1 and 2 amp power supplies, connect the transformer cable
to the AC terminal connections on the power supply circuit board.
Spade connectors are required on all connections (do not wrap
wires around terminal connections). The transformer cable should
be 2-conductor cable with 18 gauge or larger conductors. Larger
gauge wire may be required for longer runs of wire. The transformer
cable and spade connectors for 1 and 2 amp power supplies must
be supplied by the installer.
The 4, 6, and 10 amp power supplies have an internally mounted
transformer that already has an electrical cord and plug attached.
3. Feed the system power wires through one of the four knockouts
on the sides of the power supply box using the correct bushing.
Connect system power wires to the stripped wires in the power
supply box (‘+’ to ‘+’ and ‘-‘ to ‘-‘). Secure this connection using
wire nuts or crimped connectors and seal with electrical tape
(whenever possible, these splices should also be soldered for
increased reliability).
2
WARNING: Do not connect the battery or transformer power until ready for use. Allow 48
hours of constant power for the battery to charge completely for battery backup.
4. On 1 and 2 amp power supplies, connect the transformer cable to
the wall transformer terminals. Spade connectors are required for
all connections (do not wrap wires around terminal connections).
5. Once the access control system has been wired and is ready for
use, remove the plastic insulating cover from the positive battery
terminal and connect the battery wires from the power supply
circuit board to the battery terminals. Be sure to connect ‘+’ to ‘+’
and ‘-‘ to ‘-‘.
Plug the transformer into a 120 V outlet. The Transformer can be
plugged into a UPS (uninterruptible power supply) or other surge
protector for added surge protection. Do not plug the power supply
into 120V until ready for use.
On 1 and 2 amp power supplies, connect the large external
transformer to the outlet using the screw provided on top of the
transformer to prevent the transformer from falling out of the socket
and removing power to the system.
The 4, 6, and 10 amp power supplies have an internally mounted
transformer with a standard electrical plug that does not require a
screw mount.
