This installation guide assists you with installing your AI1620 SmartPass
integrated reader system (SmartPass). For additional information
regarding your SmartPass, consult the AI1620 SmartPass System Guide.
Getting Started
SmartPass is intended to be installed using outdoor grade conduit in accordance with
National Electric Code and local building standards. Installation by a licensed
electrician and building inspection may be required.
Contents of Shipping Carton
The following items are included in the SmartPass shipping carton:
•SmartPass Reader
•Pole mount bracket assembly bubble-wrapped separately
•Accessories ordered as options may also be included
Installation Accessory Kits
Table 1-1 lists optional Amtech SmartPass installation accessory items that can be
included if ordered as options:
Materials Required
You need the following materials to install SmartPass:
•A 5/32-in. Allen wrench to assemble and adjust the mounting brackets
Table 1-1 Installation Accessory Kits
Part No. Description
54-1620-001 Wall or ceiling mount kit
58-1620-001 5-ft connector cable

76-1620-006 12 V AC to 18 V AC step-up transformer

AI1620 SmartPass Field Installation Guide

•Flat tip screwdriver
•Adjustable wrench
•Audible circuit tester (buzz box)
•Tools and supplies for the power and communications connections —these may
include 1/2-in. watertight, flexible conduit and fittings, terminal strips or wire
nuts, wire strippers, tape, and heat-shrinkable tubing.
•PC with 1.44 MB floppy disk drive, MS DOS, RS-232 serial port, and a
communications cable with a DB9 or DB25 connector configured for 9600 baud,
8 bits, 1 stop bit, and no parity
•Two test tags of the same type to use in live operation - obtain test tags from your
Amtech dealer or distributor.
If mounting the SmartPass to a round pole, you need:
•Two 1/2-in. wide, stainless-steel hose clamp straps that are 12 in. long to use with
a 2-in. diameter pole or two 1/2-in. wide, stainless-steel hose clamp straps that are
24 in. long to use with a 10-in. diameter pole
If mounting the SmartPass to a wall or other flat surface, you need:
•Accessory wall or ceiling mount bracket, if additional flexibility in defining the
read zone is needed - Amtech recommends the accessory bracket if SmartPass
will be installed on any flat surface.
•Anchor hardware suitable for the surface on which you will mount SmartPass.
Because SmartPass weighs only 4.3 kg (9 1/2 lbs), 0.6 cm. (1/4-in) bolt hardware
is adequate to secure the unit to a wall or ceiling. Be sure to use high-quality
corrosion-resistant anchor hardware.
•Four hex nuts and screws 3/8-16 threaded and four washers
Electrical and Communications Requirements
All construction work at the site must be completed before installing SmartPass.
Electrical and communications cables should be installed according to all applicable
local and federal building code requirements.
Junction Box
A watertight junction box meeting applicable local and national building codes is
recommended for connecting SmartPass power and communications wiring. Amtech
recommends a NEMA Type-4 junction box with a back panel. The junction box
houses the terminal strip for communications and power connections.

Installing SmartPass

Power and Communications Cable
The appropriate cable length for power and communications depends on the physical
characteristics of the SmartPass installation site. Table 1-2 lists accessory kits
available for cabling options.
Electrical Power
A dedicated electrical power supply must be present at the site and be available to
SmartPass at all times. The power must be 16–28 V DC or 16–20 V AC. A step-down
transformer is available (North America only) to convert a 120 V AC duplex wall
outlet with ground to 18 V AC, or a step-up transformer to convert a low-voltage 12 V
AC outlet to 18 V AC. Consult your local and national electrical codes for installation
and safety requirements.
Note: SmartPasses installed outside North America require a locally supplied
transformer.
If 18 V DC or 18 V AC power is available, the transformer option is not necessary.
Amtech offers a Class C transformer accessory kit (part number 76-1620-005) for
sites where 110 V AC is available. It is the installer’s responsibility to supply
conversion equipment and wiring for other voltages. Table 1-3 contains power supply
current requirements.
Power circuits are protected internally against power surges.

Power Extension
Measured voltage at SmartPass must be at least 16 V for proper operation. Use Table
1-4 to determine the correct cable size for the necessary length of cable. The table is
an approximation.
Note: If close to the maximum length, measure voltage at SmartPass to ensure it does
not drop below 16 V.
Installing SmartPass on a Round Pole
When installing SmartPass on a round pole, the pole must be a minimum of 2 inches
in diameter and should extend 6-8 ft above the pavement level. The pole must be
installed according to local building codes.
To mount SmartPass to a pole
1. Unpack SmartPass.
A factory-mounted bracket (Figure 1-1) is attached to the back of SmartPass, and
a pole mount bracket assembly (Figure 1-2) is bubble-wrapped with SmartPass
and contains a plastic bag of 4 Allen screws and washers.

b. DCR information is from Belden catalog.
c. Calculated length is reduced by -15% to adjust for other variables such as connector contact resistance.
Length variable factor is 85%; maximum current drawn by AI1620 is 2.5; maximum allowable voltage
drop from the 18 V AC transformer secondary is 2.

2. Using the two 1.3 cm (1/2-in.) stainless steel straps, attach the pole mount
bracket assembly to the pole approximately 1.8 to 2.4 m (6 to 8 ft) above the
pavement surface. Tighten slightly so you can adjust SmartPass left or right, but
not so slightly that the straps slide down the pole.
3. Using the four Allen screws and washers supplied with the pole mount assembly,
attach SmartPass to the pole mount bracket as shown in Figure 1-3. Tighten the

AI1620 SmartPass Field Installation Guide

screws slightly so that SmartPass can be adjusted up or down but not so slightly
that the mounting assembly slips.
Figure 1-3 SmartPass Mounted Using Pole Mount Bracket
4. Adjust the assembly by pointing SmartPass to the middle of the area where tags
will be read and tighten all screws and straps slightly.
Figure 1-4 illustrates front and top views of a pole-mounted SmartPass. The
figure shows the approximate measurements used for sites where tags would be
mounted on the interior driver’s side windshield.
Note: You should determine the read zone before you tighten all screws and straps.
Refer to the "Marking the Read Zone" section on page 1-31.

Note: The dimensions in Figure 1-4 are for demonstration purposes only and are
approximate dimensions for sites where tags will be mounted on the driver’s side.
Actual dimensions vary as lane geometry varies from site to site. Adjust SmartPass to
match site and tag mounting positions to provide the most direct line of sight to the
tags.
Mounting SmartPass to a Wall or Ceiling
The basic SmartPass is supplied with a pole mount bracket assembly (Figure 1-2) that
allows you to adjust SmartPass up and down. Amtech recommends using the wall
mount bracket accessory (Figure 1-5) in addition to the pole mount bracket to provide
additional horizontal aiming flexibility when attaching SmartPass to a pole with flat

sides, or to a wall or ceiling where other structures may interfere with accurately
aiming SmartPass toward the tags.
Figure 1-5 Wall Mount Bracket Accessory
To mount SmartPass to a wall or ceiling using the pole mount and wall mount
bracket accessory kits
1. Unpack SmartPass. Set aside the pole mount bracket.
Use this bracket in the following steps to provide greater adjustment for
SmartPass. The pole mount bracket is wrapped separately from SmartPass and
contains a plastic bag of 4 Allen screws and washers.
2. Using the 5/32-in. Allen wrench, remove the factory-mounted bracket attached to
the back of SmartPass. Remove all four Allen screws and lock washers from the
bracket.
3. Unpack the optional wall mount bracket accessory kit.
