Controller and Infinet
The ACX 780/781 is a building access controller that can control access
to up to eight doors. For each door, you may control access with either
Wiegand or ABA card readers, which read access cards, or security
keypads, which accept access codes. You may also use both the card
reader and the security keypad together, for extra tight security.
The unit contains a microprocessor running at 2.4576 MHz with 1 MB
of RAM with battery backup, 512 KB of EPROM, and 4 KB of
EEPROM. In addition, it has a service port where you can connect an
LSX 280 laptop service tool.

Hardware Installation
Controller Dimensions and Weight
Each ACX 780/781 is 26 × 19 × 6 in. (660 × 483 × 152 mm) and weighs
40 lbs (18.2 kg).
Power Requirements
Caution
The ACX 780/781 should receive power from its own independent,
unswitched circuit.
The internal power supply allows an AC supply voltage of 115 V to
230 V without requiring any manual switch or jumper setting.
The ACX 780/78 1 consumes 75 VA of power at 115/230 VAC.
Cable Li m i ta tions
The maximum cable length for all buses is 4,000 ft (1200 m) at
19,200 baud (up to 32 Infinet controllers). You can extend buses beyond
4,000 ft. or put more than 32 Infinet controllers on less than 4,000 ft. by
using the InfiLink 200 amplification module. Or you can use the In-
fiLink 210 amplification module to switch to fiber optic cable and form
more complex configurations.
Note
You mu s t use s hie ld ed ca bl es f o r Infinet to ensure compliance with the
Class A FCC limits and to provide reliable communications.
Cables that form Infinet are 24-gauge, single-twisted-pair, tinned,
shielded copper wire. Use the following cables1 or their equivalents:
• Brand Rex # H 9002 (single-pair)
• Anixter # 9J2401021 (single-pair plenum cable)
1. You can also use any cables you may already have in place for ACNET or LBUS.
ACX 780/781 Installation Guide 3
The cable should have a nominal impedance of 100 Ohms and a nominal velocity of propagation of 78%.
Capacitance of Infinet cable should be nominal, below 12.5 pF/ft
(41pF/m) between conductors and below 22 pF/ft (72 pF/ m) between
the conductor connected to ground and the next conductor.
Lightning Protection
Lightning Arrestors are required at each point where an Infinet or other
wiring (such as for a card reader) enters or exits a building. Use the
following arrestor: Two pair combination gas tube/silicon avalanche arrestor, Andover Controls # 01-210 0-299.
Building Ground Requirements
Hardware Instal lation
Warning
Be sure that all Infi nity products from Ando ver Controls Corporation
are grounded to true earth ground. This kind of ground protects the
equipment from transients and other power surges in the area.
We cannot guarantee that the controller system will operate as
documented unless you properly grou nd all control lers .
Warning
Grounding should be in accordance with article 240 of the National
Electrical Code. Be sure to have your grounds inspected before you
begin the installation proc ess to be sure your municipality follows the
National Electrical Code. Many municipalities do not a nd often have
substandard electrical grounds.
An example of a substandard ground is a galvanized steel cold water
pipe. As the pipe corrodes, it does not act as a true ground. The corrosion acts as an insulator, raising the potential of the pipe with respect to
the ground.
4 Andover Controls Corporation
Hardware Installation
When lightning strikes in the area of the ins talla tion, it drastically
changes the potential of the earth. Since properly grounded Andover
Controls units respond to changes in potential more rapidly than poorly
grounded electrical systems, a poorly grounded buildi ng tries to reach
ground through the Andover Controls system. The surge of current can
destroy electronic components on the controller board.
Surges of much lower potential than lightning also impact the reliability
of Andover Controls equipment.
Inspecting the Ground
You can check your ground as follows:
1. Check yo ur ground by firs t inspecti ng the buildi ng power distributi on
panel for ea rth ground ter mination. If the ground t ermination is any of
the following, it is not adequate and must be corrected:
• Does not exist.
• Is connected to a corroded or galvanized pipe.
• Is connected using a small gauge wire thinner than 14 AWG (16
or 18AWG, for example, or less than 2.5 mm2).
2. Be sure your Andover Controls cabinet is connected to the ground
with a copper conductor that terminates at the distribution panel.
Environmental Requirements
The ACX 780/781 operates in rooms with temperatures ranging from 32
to 120°F (0° to 49°C) and with humidity between 10 and 95%,
noncondensing.
Special Wire for Card Reader Inputs
We recommend fi ve- conductor, 22- gauge ( 0. 35 mm2) shielded wire for
wiring card reader inputs.
Table 1 shows the various card brands and the maximum length for #18
gauge wire (1.0 mm2), then for #22 gauge wire (0.35 mm2).

Special Wiring for Keypad Inputs
We recommend eight-conductor, 18-gauge shielded wire for wiring keypad inputs except for the Essex unit, which requires two extra wires
bringing its total to ten conductors.
8-conductor, shielded
10-conductor, shielded for E ssex Touch Pads
You can extend the length of this cable up to 500 ft.
Output Requirements
Each ACX 780/781 has the following outputs:
• Eight door outputs that control a door through card reader or keypad
access. Each output is a Form C door latch relay rated at 120 VAC/
30 VDC, 5 A maximum. You wire these outputs just as you would a
digital/pulsed output.
Resolution of the output is 0.1 sec. You may choose to manually
override the output by setting the OVERRIDE switch to ON or OFF.
Or you can set it to AUTO to have the card reader or keypad and
control system control access through the door.
The OVERRIDE LED indicates at least one of the door outputs is on
manual control; the DOOR OPEN LED indicates the door is open.
• One auxiliary output, also a Form C relay rated at 120 VAC/30 VDC,
5 A maximum. You may want to use this output for a bell or other
audio alarm indicator.
• Eight card reader LED outputs, each rated at 4.3 V or 9 mA.

Laying Out the Si te Setu p
You may want to draw a map of where you plan to put each controller
and store it in a notebook.
Find the tag attached to each controller that gives the number of the controller. Bef ore you remove any tags, be sure the tag has all of the
following information on it:
• Location of the controller.
• Serial number.
• Model name and number.
• Communications port the Infinet connects to on the ACX 780/781
controller.
Then collect the tags. You will need to know where your controllers are
located when you later assign a name to each controller and each input
and output.
