Setting Address and DIP Switches: ACM-16AT, ACM-32A
Installation, Configuration, and Programming
5.13 Setting Address and DIP Switches: ACM-16AT, ACM-32A
Annunciator switch settings will vary according to the requirements of your control panel (see this manual’s appendix section).
5.13.1 DIP Switch Summary: ACM-16AT, ACM-32A
5.13.2 Addressing ACM-16AT and ACM-32A
Set the address with rotary switches on the back of the annunciator (see Figure 5.4). Turn the arrow with a small flat-head until it points to
the correct digit. The rotary switch on the left sets the ‘tens’ digit; the switch on the right sets the ‘ones’ digit.
Up to 32 devices (such as ACMs, LDMs, and AFMs) can be connected to the EIA-485 circuit; the number of addresses available and the
number of devices that can answer back depend on the control panel. Refer to your control panel documentation for valid addresses.
Using ACS and a UDACT on the Same Control Panel
The use of a UDACT Universal Alarm Communicator/Transmitter and an Annunciator Control System on the same control panel will alter
the assignments of the trouble LEDs on ACS Points 3, 4, 5, 6, 7, and 8. Refer to the
UDACT installation manual
#50050 and the literature for
the respective fire alarm control panel for further details.
5.13.3 Configuring Number of Expander Modules
Indicate the number of expanders connected to each ACM-16AT/ACM-32A by setting the DIP switch on the end of the annunciator, as
shown in Table 5.2.
5.14 Supervising Devices with ACM-16AT, ACM-32A
If using ACM-16AT or ACM-32A, the normally closed Trouble Input on those modules can be used for supervising local power sources or
other devices. If employed, all changes in status (to and from the trouble state) will be sent to the control panel in the event of device failure
or restoral. If not used, a jumper must be installed across these terminals TB1-6 and TB1-7; without this jumper, the control panel will regis-
ter a trouble condition. (See Figure 5.20.)

Function
1
Manual override of control relays (not supported by all control panels; see appendix section)
2, 3
Expanders installed: Set these switches according to how many expanders are installed at the address. See Section 5.13.3,
“Configuring Number of Expander Modules”
4
Eight-point Shift (not supported by all control panels; see appendix section)
5
Receive Only (duplicates another annunciator operating at the same address; see Section 4.4, “Receive/Transmit and Receive
Only Configuration”)
6
Piezo disabled when set to “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. NOTE: Point-control switches cannot execute system
control functions when set to “ON” (Details of function vary according to control panel; see appendix section)
8
Flash inhibit. Disables flashing LEDs and prohibits piezo from sounding.
NOTE:
Switch locations are illustrated in Table 5.4. To set a DIP switch “ON”, push it towards the green circuit board.

short circuit (jumper) does
not exist between terminals
TB1-6 and TB1-7, the
control panel will register a
