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.
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.
REAR VIEW The rear of the alarm unit includes the following: 1. 2. 3. 4. 5. 6. 7.
INSTALLATION The following items are supplied: • • • ALM2064 Alarm Interface Unit 120 VAC power cord 220 VAC power cord • • • Pelco screwdriver 4 #10 screws with nylon washers 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.
WIRING ALARMS 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.
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 that unused inputs must also be wired. Refer to Figure 6. INDIVIDUAL ALARM WIRING CONDITIONS 00711 Figure 6.
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. If wiring for a normally closed condition, unused inputs must be shorted. Refer to Figure 7. INDIVIDUAL ALARM WIRING CONDITIONS 00712 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.
WIRING EXTERNAL ALARM INPUTS USING ANALOG CIRCUITRY Figure 9 summarizes what is required in supervised and unsupervised modes to wire external alarm inputs using analog TTL/CMOS circuitry rather than alarms. ALARM ALARM ALARM ALARM ALARM ALARM 00714 Figure 9.
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. 2. 3. Remove the mating plug from the relay output connector. Place the wires into the relay out wiring slots. Tighten the screws to secure the wires. NOTE: Refer to the REL2064 Installation/Operation Manual for instructions on wiring relays to peripheral equipment. 00715 Figure 10.

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.
TROUBLESHOOTING PROBLEM SOLUTION Why is the unit not operating as it should? Make sure the power cord is plugged in and the power switch is turned on. If the unit still fails to operate, remove the front panel and press the reset button. Make sure the DIP switch settings are correct. Check the input power fuse. You may need to replace it. Refer to Figure 14. What is the DB9 port used for? This port is used for diagnostics.
