IMPORTANT SAFEGUARDS AND WARNINGS

1. Read, keep, and follow these instructions.

2. Heed all warnings.

3. There are no user-serviceable parts inside this unit. Only authorized service personnel may open the unit.

4. Installation and servicing should only be done by qualified service personnel and conform to all local codes.

5. WARNING: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture if this unit is designed for indoor

use only.

6. Unless this unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X, 6 or 6P enclosure, it is designed for indoor use only and it must not be installed where exposed to rain or moisture.

7. Do not expose this unit to dripping or splashing. Do not place objects filled with liquids, such as vases, on this unit.

8. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.

9. The installation method and materials should be capable of supporting four times the weight of the unit and equipment.

10. Do not install near any heat source.

11. Only use attachments/accessories specified by the manufacturer.

12. Clean only with dry cloth.

13. Do not defeat the safety purpose of the polarized or grounding-type plug.

14. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the unit.

15. Unplug this unit during lightning storms or when unused for long periods of time.

The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit.

This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit.

Please thoroughly familiarize yourself with the information in this manual prior to installation and operation.

FOR QUALIFIED SERVICE PERSONNEL ONLY

1. Only use replacement parts recommended by Pelco.

2. After replacement/repair of this unit’s electrical components, conduct a resistance measurement between line and exposed parts to verify the exposed parts have not been connected to line circuitry.

CAUTION:

RISK OF ELECTRIC SHOCK.

DO NOT OPEN.

OVERVIEW

DESCRIPTION

The REL2064 Relay Interface Unit provides up to 64 single-pole, single-throw (SPST) dry contact outputs for direct or automatic control of peripheral equipment. Using Pelco’s proprietary M protocol, the relay unit communicates with Pelco’s CM6800 matrix switcher via an RS-485 communication interface. The relay unit can be located remotely from the system controller and still communicate back to the central system when an alarm occurs.

Other features include the following:

• Multiple units can be cascaded to provide multiple relay contact points on a single M port connection.

• Relay output contacts can be configured for normally open (N.O.) or normally closed (N.C.) operation.

• With the memory feature, relay groups can retain their contact position in the event of a power failure or front panel reset.

• The unit is powered by an auto-ranging power supply.

• The unit occupies one rack unit (1.75 inches or 4.45 cm), accommodating multiple types of mounting.

FRONT VIEW

The left side of the front panel includes the green power LED light. This light comes on at power-up.

The right side of the front panel includes the red data LED light. This light continually flashes on and off at a regular rate (about one-second intervals) until the unit is online and communicating with the CM6800. Once online, the LED remains ON. If for any reason communication is lost, the LED flashes again until communication is re-established.

When you remove the front panel, you have access to a reset button and configuration DIP switches.

REAR VIEW

The rear of the REL2064 unit consists of the following:

1. Four groups of 16 contact pairs, each with mating plugs for the attachment of peripheral equipment; only the group for the first 16

2. One RS-485 output communication port (RJ-45 type connector)

3. One RS-485 input communication port (RJ-45 type connector)

4. One RS-232 diagnostic communication port (DB9 type connector)

5. The grouped input power functions consisting of input power terminals, a fuse, and an on/off switch

contact pairs is shown in Figure 2 with mating plugs

INSTALLATION

The following items are supplied:

• REL2064 Relay Interface Unit

• 120 VAC power cord

• 220 VAC power cord

• Pelco screwdriver

• 10-foot (3 m) straight RJ-45 cable (8-conductor)

•4 #10 screws with nylon washers

MOUNTING

Install the relay unit in a 19-inch rack. The unit occupies one rack unit (1.75 inches or 4.45 cm) of space. You can mount the relay unit to something other than a standard 19-inch rack by relocating the rack ears to another location.

WIRING RELAYS

The relay unit has four groups of relay contacts. Each group represents 16 pairs of relay contacts:

• Group I – 1-8, 9-16

• Group II – 17-24, 25-32

• Group III – 33-40, 41-48

• Group IV – 49-56, 57-64

Each of the four groups contains two connectors with input mating plugs. The top connector is for the first eight pairs of relay contacts and the bottom connector is for the last eight pairs of relay contacts. Each mating plug has 16 screw terminals and 16 pins. When you place a wire into a pin, tighten the screw to secure it.

Refer to Figure 4 to determine the screw terminal number for a particular contact. The numbers that appear on the mating plugs in Figure 4 are for illustration only. The terminal positions on the actual physical plugs are not numbered.

Refer to Figure 5 for wiring the relays to peripheral equipment.
