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

Wiring Inputs

Caution

Do not remotely ground any part of the sensor wiring. Remote grounds connected to the ACX 780/781 return terminal could make the controller operate incorrectly or damage the equipment. The signal return is not true earth ground. It is a n electronic refer ence point necessary to interpret the sensor properly. Do not externally ground sensor or switch terminals that return to the ACX 780/ 781.

Caution

Card readers requ i re sh i e l ded wiring . Although two-wire inputs us ually funct ion properly with unshielded

Hardware Instal lation

sensor wire, you may need shielded wire if you run the wire as follows:

• In the same conduit with other noise-generating conductors such as 50/60 Hz AC power.

• In long runs close to large power-consuming or power-generating equipment that can produce 50/60 Hz noise.

We recommend you run input wiring in a conduit separate from AC power or output wiring and avoid long wiring runs.

The “supervisory” in puts are on the left side of the A CX 780/781. Input wires should enter from the left side. Notice that the inputs are labeled RET, IN1, IN2, RET, IN3, IN4, RET, IN5, IN6, and so on, for up to 32 inputs. The first return terminal goes to the first two inputs, the second to the next two inputs, and so on.

18 Andover Controls Corporation

Hardware Installation

Caution

Follow the rules below when wiring inputs and outputs:

• Never lay wires across the surface of the printed circuit board. You should bring input wires in from the left and output wires in from the bottom.

• High voltage AC Power wiring should be routed to the conduit opening nearest the AC power terminals.

• Do not bundle or route AC Power wiring with low voltage input or output wiring.

• Bundle excess wires toward the back of the cabinet to avoid any contact with circuit boards.

• Wires should never be within 1 in. (25 mm) of any component on the printed circuit board.

• Keep cabinet free of foreign materials (extra power supplies, relays, and so on).

• Be careful when stripping wire not to drop small pieces of wire inside the cabinet.

If you violate any of these rules, the controller could malfunction.

Supervisory Input Circuits

All 780/781 controller series inputs are supervisory inputs. The follow- ing drawings depict the six types of supervisory inputs that exist—three normally closed and three normally open types. After the drawings, there is an explanation of which types are recommended for access control installations.

Figure 6 shows the three types of normally closed supervisory inputs.

Powering Up the ACX 780/781

Warning

Before powering up the controller, be sure the board is jumpered for the correct input voltage.

Before you proceed, be sure the following are correct:

1. Be sure the battery is conne cte d.

2. Be sure the AC power source is wired properly. Check to be sure all three wires have been connected.

3. Be sure the controller has a true earth ground.

4. Be sure you have used the proper cables/wires and the correct lengths.

5. Be sure you have properly labeled the tag with the name of the controller before removing the tag.

6. Be sure the Infinet cable has been properly wired.

7. Be sure the Infinet cable shields are properly connected.

If you have completed all previous sections in this manual, you are now ready to power up the controller.

Turn on the AC power source (or close the power connection) and switch AC power to ON. The controller starts automatically. The following occurs (also occurs when you press RESET):

1. If the controller has been off, relays remain off. If you have pressed RESET, relays deenergize.

2. While you press RESET, all power LEDs on the Power Supply Status Display light up.

4. The CPU light on the Power Supply Status Display (inside cabinet) begins flashing and flashes every .1 sec if all is normal. If the controller fails a ROM test, the CPU light flashes every .2 sec. If the controller fails a RAM test, the CPU light flashes every .025 sec. If the controller fails any other software test, it flashes every .05 sec.

5. The AC_ON light on the front of the cabinet tur ns on and remains on as long as the unit is receiving power.

6. The TD light (for Infinet) may not flash at this time. Once you have set up the Infinet controller in the software and assigned the controller an ID, the TD light imm e diate ly s tarts fla s hing to s how data is being transmitted.

7. The RD light (for Infinet) begins flashing only if data is being received from other controllers on the network. This may not happen immediately.

8. If any of the nine door outputs is not set to AUTO, the OVERRIDE light (inside cabinet) remains steadily on.

9. The status lights on the front door of the cabinet, labeled with output numbers, turn on if the output value is ON (see Figure 24).

Figure 23 shows the status lights inside the cabinet, that also turn on when the output value is ON.
