NFS-3030 Systems (UL 8th), NFS2-3030 Systems and NCA-2 Systems (UL 9th)
Configurations for Specific Applications with NFS-3030, NFS2-3030,
The switch numbers given below are for SW28 on the ACM-24AT, and for the 8-pin DIP switch on the ACM-16AT and ACM-32A.
This remote annunciator must be programmed to annunciate the status of all points in the system, either by device/module, or by grouping
points into logic zones and annunciating the status of those zones. Every point in the system must be represented by at least one annunciator
point at each remote location.
I.6.2 Speaker and Telephone Mode with NFS-3030/NFS2-3030/NCA-2
To execute audio functions, use an ACM-24AT or ACM-16AT set to address 1. This annunciator (and any expanders) must be installed adja-
cent to the AMG-1 and points assigned for AMG control cannot be used for common system annunciation, or for the manual control of cir-
cuits and relays. Telephone points can be mapped to unused points on this annunciator or on another ACM-24AT or ACM-16AT annunciator
for the control of telephone circuits. Set the DIP switches as follows. The switch numbers given below are for SW28 on the ACM-24AT, and
for the 8-pin DIP switch on the ACM-16AT.
Dip Switch
When configured as outlined in Speaker and Telephone Mode, the ACM-24AT or ACM-16AT will function as follows:
•
All new conditions (except telephone call-in) The piezo will not sound and LEDs will not flash.
•
Telephone call-in: The piezo will sound and both the point active and trouble LEDs for the respective telephone point will flash.
Pressing the telephone point switch on the ACM-24AT or ACM-16AT will silence the piezo and illuminate LEDs steadily. The
NFS-3030/NFS2-3030/NCA-2 will indicate telephone circuit connection by turning off the trouble LED.
I.6.3 Manual Override with NFS-3030/NFS2-3030/NCA-2
Manual Override allows the on/off control of relays to be placed under sole control of the annunciator switches. When Dip Switch 1 is ON,
and the Manual Override key has been pressed on the ACM-24AT or ACM-16AT, the annunciator is in Manual Override mode, and the yel-
low override LED is ON. Pressing the key again returns the annunciator to automatic mode. In manual mode, automatic (control-by-event)
commands from the NFS-3030/NFS2-3030/NCA-2 are ignored, and relays may be switched on/off only from the annunciator switches. In
automatic mode, the relays may be switched by either the NFS-3030/NFS2-3030/NCA-2 or the annunciator switches.
When in manual override mode, all points displayed on the ACM-24AT or ACM-16AT and all its expanders will ignore subsequent Control-
by-Event (CBE) commands from the panel.
Manual Override Mode can be entered by pressing the Manual Override switch on the ACM-24AT or ACM-16AT module (Use special
slide-in label).
•
The Manual LED on the ACM-24AT or ACM-16AT module will illuminate steadily.
•
The NFS-3030/NFS2-3030/NCA-2 will register an ANNUNCIATOR TROUBLE condition.
•
The state of the each annunciator point will remain the same as before.
•
The output circuits can now be controlled via their point switches.
Switch #
ACM-24AT and ACM-48A
ACM-16AT and ACM-32A Function
1
Manual override: Set switch “OFF” for this application.
2, 3
Expanders installed: Set these switches according to how many expanders are installed at the address. See Section 5.12.3 for
ACM-24AT/ACM-48A; see Section 5.13.3 for ACM-16AT/ACM-32A.
4
Not used; set to OFF
Eight-Point Shift: Set to “OFF”.
5
Receive Only: Set switch accordingly
6
Piezo Disable: The piezo must sound - this switch must be set to the “OFF position.
7
Switch Inhibit: Set this switch “ON” to disable the point control switches on the annunciator and prevent them from executing system control
functions. When inhibited, the switches will serve as local Lamp Test switches only. In addition, the Acknowledge/Lamp Test switch will
function only in a local capacity unrecognized by the system.
8
Flash Inhibit: Set switch to the OFF position for this application.
NOTE:
More than one monitor-type device may be programmed to a single annunciator point. This multiple-mapping of initiating devices will
operate the point active and trouble LEDs of an annunciator point with Boolean “OR” functionality.

6
Piezo Disable: Set this switch “ON” for this application unless the annunciator and AMG-1 are not located adjacent to the NFS-
3030/NFS2-3030/NCA-2. In that case, the piezo must sound and the switch must be set to “OFF”.

Switch Inhibit: Set this switch”OFF” for this application.
8
Flash Inhibit: Set this switch “ON” for this application.

CAUTION: MANUAL CONTROL
THE NFS-3030/NFS2-3030/NCA-2 CONTROL-BY-EVENT WILL NOT OVERRIDE THE MANUAL CONTROL SETTING OF
THE ACM-24AT OR ACM-16AT MODULE. TO RETURN THE ANNUNCIATOR TO AUTOMATIC MODE, PRESS THE
MANUAL OVERRIDE SWITCH AGAIN (TOGGLE ACTION). SET THE DIP SWITCHES ON A MANUAL OVERRIDE
ANNUNCIATOR AS FOLLOWS.THE SWITCH NUMBERS GIVEN BELOW ARE FOR SW28 ON THE ACM-24AT, AND FOR
THE 8-PIN DIP SWITCH ON THE ACM-16AT.
