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.

OVERVIEW

DESCRIPTION

The ALM2064 Alarm Interface Unit provides alarm monitoring capability for up to 64 alarm inputs. Using Pelco’s proprietary M protocol,
the alarm unit communicates with Pelco’s CM6800 matrix switcher via an RS-485 communication interface. The alarm 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 alarm contact points on a single M port connection.

• Alarm inputs can be configured in two groups of 32 for supervised or unsupervised mode.

• The relay output activates when an alarm is triggered.

• 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 alarm LED. When the light is a solid red, the alarm unit is online. When the light is off,
the unit is offline. In any valid alarm condition, this light starts blinking and only stops when the alarm is no longer active.

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

REAR VIEW

The rear of the alarm unit includes the following:

1. Four groups of alarm inputs (labeled I, II, III, and IV) with removable mating plugs

2. One alarm output relay

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

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

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

6. A green power LED light, which mirrors the green LED light on the front panel

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

INSTALLATION

The following items are supplied:

• ALM2064 Alarm Interface Unit • Pelco screwdriver

• 120 VAC power cord • 4 #10 screws with nylon washers

• 220 VAC power cord • 10-foot (3 m) straight RJ-45 cable (8-conductor)

MOUNTING

Install the alarm unit in a 19-inch (48.26 cm) rack. The unit occupies one rack unit (1.75 inches or 4.45 cm) of space. You can mount the
alarm unit to something other than a standard 19-inch rack by relocating the rack ears to another location.

STANDARD 19-INCH (48.26 CM) RACK MOUNT

CONNECTING TO THE CM6800

Connect the supplied RJ-45 straight cable from the ALM2064 OUT port to the CM6800 COM 3 port. The active pin-outs are associated
with the four outer pins: 1, 2, 7, and 8. Refer to Figure 4.

If you want to place the alarm unit some distance from the CM6800, the RS-485 communication from the alarm unit to the controller should
not exceed 4,000 feet (1,219 m). You need an RJ-45 wall-block terminal (part number CON12J008Z03G0Z) if operating from a remote site.

To cascade two alarm units, connect a straight cable from the OUT port of the second alarm unit to the IN port of the first alarm unit. The
first unit is the one you connect to the CM6800.
