Configurations for Specific Applications
5
Receive Only: Set switch accordingly
6
Piezo Disable: When the annunciator and AMG-1 are not located adjacent to the AM2020/AFP1010, as in this application, the
piezo must sound and the switch must be set to "OFF".
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.
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 software zones and annunciating the status of those zones. Every point in the system must be represented by at least one annunci-
ator point at each remote location.
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.
D.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 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
Switch #
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,
"Configuring Number of Expander Modules" for ACM-24AT/ACM-48A; see Section 5.13.3, "Configuring Number of Expander
Modules" for ACM-16AT/ACM-32A.
4
Not used; set to OFF
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
AM2020/AFP1010. 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.
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
AM2020/AFP1010 will indicate telephone circuit connection by turning off the trouble LED.
D.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 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 AM2020/AFP1010 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 AM2020/AFP1010 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 AM2020/AFP1010 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.
CAUTION: MANUAL CONTROL
!
THE AM2020/AFP1010 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.
