3.5 System Inputs and Outputs
The CP-3000 has 10 dry contact, 1 auxiliary and 1 class A or 2 class B NAC output circuits available.
Some are programmable and some are non programmable. Each output and function is explained
below. Refer to figures 6 and 7 for wiring diagrams of these outputs. All diagrams are shown with
system power connected and control panel in normal mode.
3.5.1 Alarm A, B, C, D Contacts (TB2 Terminals 9-24)
These 4 normally open outputs will operate when any alarm signal of the corresponding A, B, C or D
type is being processed. For example if alarm A has been designated for smoke detectors and a
smoke detector alarm is received the alarm A relay will activate. When alarm C is configured for
supervisory then the alarm C relay will serve as a supervisory output. These outputs can be power
limited or non-power limited depending on the equipment they are connected to. Power limited and
non-power limited circuits must be separated by at least .25” within the enclosure and run in different
conduit. These outputs are also used when connecting the control panel to a communicator. They
have double terminals so that an end of line resistor can be connected in different terminals than
those used for wiring connections allowing connected equipment to properly monitor any wiring fault.
Refer to the communicator section of this manual for connection of a communicator. The contacts are
rated at 28Volts D.C. 2 Amps resistive. Acceptable wire size for connection is 16-22awg.
3.5.2 Trouble Contacts (TB2 Terminals 1-8 N.O. and TB3 Terminals 3-6 N.C.)
There are 2 normally open and 2 normally closed trouble dry contact outputs available on the CP-
3000. They will operate during processing of any of the trouble conditions listed in the system
operation section of this manual. These also serve as the fail safe relays that monitor for system
processor failure and total power down of the control panel. The outputs can be power limited or non-
power limited depending on the equipment they are connected to. Power limited and non-power
limited circuits must be separated by at least .25” within the enclosure and run in different conduit.
The normally open outputs have double terminals so that an end of line resistor can be connected in
different terminals than those used for wiring connections allowing connected equipment to properly
monitor any wiring fault. The terminal output designations shown in figure 6 are with system power
applied in normal standby mode. One of the normally open trouble outputs is used when connecting
the control panel to a communicator. Refer to the communicator section of this manual for connection
of a communicator. When a power loss trouble occurs at the system or a repeater, activation of the
trouble relays will be delayed by 60 minutes. This time is programmable and options are explained in
the programming section of the manual. The contacts are rated at 28Volts D.C. 2 Amps resistive.
Acceptable wire size for connection is 16-22awg.
3.5.3 Alarm Contacts (TB3 Terminals 7-12)
These are 2 form C outputs that can be separately programmed to activate when any or all of the 4
alarm types A, B, C or D are in process. These outputs can be power limited or non-power limited
depending on the equipment they are connected to. Power limited and non-power limited circuits
must be separated by at least .25” within the enclosure and run in different conduit. The contacts are
rated at 28Volts D.C. 2 Amps resistive. Acceptable wire size for connection is 16-26awg. Note: Alarm
C can be designated for sprinkler supervisory. When this programming choice is made make sure to
program these relays so that one of them will activate on alarms A, B and D only and the other relay
will activate on supervisory alarm C only.
