NFS-3030 Systems
PN 15842:K 7/23/2002 91
V.6.2 Speaker and Telephone Mode
To execute audio functions, use an ACM-24AT or ACM-16AT set to address 1.
This annunciator (and any expanders) must be installed adjacent to the AMG-1
and points assigned for AMG control cannot be used for common system
annunciation, or for the manual control of circuits 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 will indicate
telephone circuit connection by turning off the trouble LED.
V.6.3 Manual Override
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 yellow 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 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 or the
annunciator switches.
Switch
# ACM-24AT Function ACM-16AT 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 4.12.3 “Configuring Number of Expander
Modules” for ACM-24AT/ACM-48A; see Section 4.13.3 “Configuring Number of
Expander Modules” for ACM-16AT/ACM-32A.
4 Not used; set to OFF Eight-Point Shift: Always set this switch
“OFF” in NFS-3030 systems.
5 Receive Only: Set switch “OFF” for this application.
6 Piezo Disable: Set this switch “ON” for this application unless the annunciator and
AMG-1 are not located adjacent to the NFS-3030. In that case, the piezo must sound
and the switch must be set to “OFF”.
7 Switch Inhibit: Set this switch”OFF” for this application.
8 Flash Inhibit: Set this switch “ON” for this application.
