NCA-2 Systems (UL 9th)
For NCA connections, see Appendix H.
I.1 Capabilities
When installed with NFS-3030/NFS2-3030 or NCA-2, annunciators can be programmed to annunciate the status of addressable devices,
general zones, logic zones, and several system control functions:
•
Devices
– Intelligent Detectors
– Monitor and Control Modules
– Addressable Manual Pull Stations
– Wireless Devices
– Panel Circuit Modules (NFS-3030 only)
•
Zones
•
Logic Zones
•
System Controls
– Acknowledge
– Signal Silence
– System Reset
– Lamp Test
– Drill
– Disable
– Monitor
– Control
– Telephone
•
XP Series Transponder System
– Power and Audio Supply Supervision
– XP Series Form-C Alarm and Trouble Relays
– Control, Monitor, and Relay Module Circuits
I.2 Connecting the EIA-485 Circuit
One ACS circuit may be connected to the NFS-3030/NFS2-3030 or NCA-2 as shown in the accom-
panying illustration. The NFS-3030/NFS2-3030/NCA-2 must be at the end of the EIA-485 circuit.
See Section 4.3 for details and notes about EIA-485 requirements.
I.3 Providing Power to Annunciators
The annunciator’s power supply is connected to TB6 on the AMPS-24/E, TB6 on CPU2-3030, or TB6 on NCA-2, as shown in the accompa-
nying illustrations. The power run to the annunciator does not require a Power Supervision Relay. Loss of power is inherently supervised
through a Communications loss. This 24 VDC output is supervised, filtered, and non-resettable. TB6 on AMPS-24/E is power-limited only if
the +5V output on the terminal block is not used.
NOTE:
Refer to the appropriate FACP manuals for more information.
