ACX 780/781 Installation Guide 3
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 780/781 consumes 75 VA of power at 115/230 VAC.
Cable Limitations
The maximum cable length for all buses is 4,000 ft (1200 m) at
19,200 baud (upto 32Infinet controllers).You can extendbuses 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 must use shielded cables for 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 cables1or 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.
Technical Manuals Online! - http://www.tech-man.com
firealarmresources.com

Hardware Installation
4 Andover Controls Corporation
The cable should have a nominal impedance of 100 Ohms and a nomi-
nal 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 ar-
restor, Andover Controls # 01-2100-299.
Building Ground Requirements
Warning
Be sure that all Infinity products from Andover 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 ground all controllers.
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 process to be sure your municipality follows the
National Electrical Code. Many municipalities do not and 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 corro-
sion acts as an insulator, raising the potential of the pipe with respect to
the ground.

firealarmresources.com

Hardware Installation
ACX 780/781 Installation Guide 5
When lightning strikes in the area of the installation, 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 building 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 your ground byfirst inspecting the building power distribution
panel for earth ground termination. If the ground termination 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 five-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).

pad inputs except for the Essex unit, which requires two extra wires
bringing its total to ten conductors.
8-conductor, shielded
10-conductor, shielded for Essex 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 oneof the door outputs is on
manual control; the DOOR OPEN LED indicates the door is open.
• One auxiliary output, alsoa Form Crelay ratedat 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.

Input Requirements
Caution
Andover Controls inputs are designed to be used with the specified card
readers, two-wire door switches, two-wire motion sensors, and other
two-wire input devices; they do not provide sufficient power to operate
sensors requiring an external power supply of 12 or 24 VAC/DC.
Each ACX 780/781 controller has the following inputs:
• Eight card readerinputs that receive either the Wiegand formator the
standard ABA format. You set the format later, in the software.
(UL listed systems must use model 30387 Sensor Engineering card
readers.)
Maximum data rate for each card reader—1 ms between bits with a
50 µs bit width. Maximum number of bits per card is 256.
Maximum power available to each card reader is 35 mA at 5 VDC.
If the card reader requires 12 or 24 VCD, it requires an
external power supply.
• Eight keypad inputs. You can place keypads near the door as an
alternative to a card reader. The person punches in an access code that
the controller recognizes before allowing the person access. Each
keypad has up to 12 keys and eight wires.
• Thirty-two supervisory inputs (1 through 32) that you canuse forany
of the following types of inputs:
— Door switch that indicates the status of the door—open or closed.
Must have a 10 KΩresistor in series if normally closed or in
parallel if normally open. The resistor allows the input to detect
tampering. Refer to the Infinity CX Programmer’s Guide for
details. Required.

ACX 780/781 Installation Guide 9
— An exit request input, usually a motion sensor that determines
someone is approaching the door or a push button that you must
press to leave the area. Must have a 10 KΩresistor in series if nor-
mally closed or in parallel if normally open. The resistor allows the
input to detect tampering. Refer to the Infinity CX Programmer’s
Guide for details. Optional.
Each supervisory input reads the input voltage level and provides
switch position and tampering information.
Each supervisory input can have up to 200 ft of #22 AWG (up to
60 m of 0.35 mm2) 100% shielded wire.
• Two built-in tamper switches. The first switch reacts when someone
opens the cabinet door. The second switch reacts when the cabinet
has been removed from the wall. When the switch is open, the
cabinet tamper alarm is ON.
Laying Out the Site Setup
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 con-
troller. Before 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.
