Overview

The SMART Pac III is an in-line power controller designed to protect and
extend the life of HES electric strikes and other ASSA ABLOY electrified prod­ucts. The built-in poly switch and zener diode protect the host system from
possible reverse current surges, while a reduced voltage ‘step down’ extends
the life of the electric strike by reducing operating temperature. The SMART
Pac III can provide a DC output with an input ranging from 10.5 to 33 VDC or

10.5 to 30 RMS AC.

The SMART Pac III can also be used to troubleshoot installation problems. The
SMART Pac III’s built-in LED can be used as a simplified voltage meter that
indicates the power supply voltage at the installation. In addition, the SMART
Pac III has a two-position Slide Switch that matches the SMART Pac III output
voltage to the operating voltage of the electric strike. Note: The input voltage
must be in range of the voltage required by the electric strike.

Installation Directions

1. Connecting the SMART Pac III: Connect the SMART Pac III to the wires coming from the
access control panel as shown on Page 3, using either the 12V or 24V pigtail provided with the
HES electric strike. If using other ASSA ABLOY electrified products, refer to the wiring schematic
on Page 4.

2. Using SMART Pac III to confirm correct input voltage: Set the SMART Pac’s slide switch to
the voltage of the power supply (see Page 3) and activate power. The behavior of the SMART
Pac’s LED Status Indicator will communicate the following:

 Voltage input, and if it is within the input requirements listed on Page 3

 Correct position of the the SMART Pac’s slide switch for the voltage input

3. Resolving Fault Codes: A blinking or unlit LED indicates corrective action is needed.

a. Using the LED STATUS INDICATOR TABLE below determine the appropriate
corrective action.
b. Remove power to the SMART Pac III and correct the error condition.
c. Wait 10 seconds and re-power the unit. This will reset the LED indicator.

Warning: The slide switch configures the wiring to the electric strike. It does not control the
SMART PAC III’s voltage output and will not prevent an overload condition if set improperly. The
voltage rating of the electric strike must match the voltage output of the power supply (e.g.: Use
a 24 Volt strike if you have a power supply rated at 24 Volts.)

If using an electric strike and/or additional devices in series with a single SMART PAC III, do not
exceed a current rating of 750 MA at 25 C.

4. Connecting the Electric Strike: With no power supplied to the SMART Pac III, connect the
electric strike. Verify the operation of the electric strike and a steady LED color when power is
present.

NOTE: A self re-setting poly switch is built into the SMART Pac III to prevent damage to the
electric strike in an over-current situation or downstream short. Normally, the SMART Pac III will detect
over current situations and shut down the power output before the poly switch opens. If the poly switch
trips there will be no voltage output and no LED status.
