V.5 Configuring Annunciators for NFS-3030
DIP Switch Settings Note:
The switch numbers given below are for SW28 on the ACM-24AT and
ACM-48A, and for the 8-pin DIP switch on the ACM-16AT and ACM-32A.
Address and DIP switches must be set before the annunciator will operate
properly. See Section 4.2 “Connections and Switches” for switch locations.
Note: See Section 4.12.1 “DIP Switch Summary: ACM-24AT, ACM-48A” and
Section 4.12.4 “Speaker Control Mode” for details about SW32 on ACM-24AT
and ACM-48A.
Switch
# ACM-24AT and ACM-48A ACM-16AT and ACM-32A Function
1 Manual override: Set “ON” when the annunciator is used for manual override of control
relays.
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 this switch “ON” for each annunciator that will provide the same
information as another annunciator in a different location. (When two or more
annunciators hold the same address, all but one must be configured as “Receive Only”
annunciators.)
6 Piezo Disable: Set this switch “ON” to disable the piezo from sounding for any event.
(The piezo will also be disabled if Flash Inhibit is “ON”.)
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 this switch “ON” to disable the flashing of LEDs associated with
unacknowledged events. Flash Inhibit also disables the piezo from sounding.
