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 In any valid alarm condition, this light starts blinking and only stops when the alarm is no longer active.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.

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.

WIRING ALARMS
O
All alarm wiring takes place using the four groups of connectors located on the rear of the alarm unit. The alarm unit has four groups of
inputs. Each group represents 16 alarm inputs:
•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 of wired alarm inputs are classified into modes (or contact types): supervised and unsupervised. This is important
for the following reasons:
1.The operational mode (supervised or unsupervised) for each 32-input group is determined solely by the DIP switch positions of SW1.
Refer to Figure 5.
2.Integrating supervised and unsupervised wiring modes within the same group is not allowed.
3.In unsupervised mode, it is not possible to have alarms wired for both normally open and normally closed operation in the same
alarm group.
4.If wiring a group of alarm inputs as supervised, no unwired inputs are allowed as this would result in a constant alarm condition. All
unwired inputs should have a 10-kohm resistor wired across its input and associated GND connection. Refer to Figure 6.
5.If wiring a group of alarm inputs as unsupervised and normally closed, no unwired inputs are allowed as this would also result in a
constant alarm condition. Alarm inputs not used must be shorted out between the alarm input and its associated GND connection.
Refer to Figure 7.

SUPERVISED MODE
Use this wiring mode if security is of utmost importance. Alarm inputs wired in supervised mode maximize the detection of tampering by
driving a constant current through a 10-kohm load. If a deviation in the steady current occurs, the alarm goes off. Please note thatunused inputs must also be wired. Refer to Figure 6.
INDIVIDUAL ALARM WIRING CONDITIONS

8C1517M-A (11/02)
UNSUPERVISED MODE
This wiring mode is easily defeated and should not be used in critical situations. For example, if you wire an alarm as unsupervised and
normally open, and a wire is cut, the alarm does not go off. If wiring for a normally open condition, unused inputs can be left unwired. Ifwiring for a normally closed condition, unused inputs must be shorted. Refer to Figure 7.

MAKING THE ALARM CONNECTIONS
Each of the four groups contains two connectors with input mating plugs. The top of each mating plug has 16 screw terminals and the
front has 16 pins. The figure below indicates how the pins alternate between alarm inputs and their associated GND (ground) input
connection. For example, pins 1 and 2 are associated with alarm input 1. This applies to all four groups of alarm inputs.
Remove the mating plugs from the connectors to install the wiring. The top connector of each group is for the first eight alarm inputs, and
the bottom connector is for the last eight alarm inputs. The 16 screw terminals secure the alarm wires.

RELAY OUTPUT WIRING
The alarm unit activates the relay when a valid alarm condition is sensed.
To wire the relay output, you must do the following:
1.Remove the mating plug from the relay output connector.
2.Place the wires into the relay out wiring slots.
3.Tighten the screws to secure the wires.
NOTE: Refer to the REL2064 Installation/Operation Manual for instructions
on wiring relays to peripheral equipment.
SETTING THE DIP SWITCHES
The positioning of the DIP switches for SW1 and SW2 determines how your alarm unit operates. You are able to set the baud rate, alarm
range, alarm group and mode, and local device address.
NOTE: You must recycle power if you make changes to the DIP switches after the alarm unit has been turned on.

OPERATION
The function of the alarm unit is to physically monitor all alarm inputs for a change of state.
Green LEDs on the front and rear panels light when the power is turned on.
The red alarm LED indicates whether the unit is offline or online. This light starts blinking in any valid alarm condition and only stops
when the alarm is no longer active.
For supervised inputs, the unit monitors each alarm input for a constant current through the wiring of the alarm circuit. The alarm consists
of either a 10-kohm resistor connected in series with a normally closed contact or a 10-kohm resistor connected in parallel with a normally
open contact.
For unsupervised inputs, the unit monitors each alarm input for a change of state from that previously defined by DIP switch positions as
being normally open or normally closed. A change from the defined state (normally open to normally closed or normally closed to normally
open) activates an alarm condition.
The alarm unit activates the relay whenever a valid alarm condition is sensed. If multiple alarm points are activated on a given alarm unit,
the relay remains engaged as long as any of these alarm conditions remain active.
