Installation, Configuration, and Programming
40 PN 15842:K 7/23/2002
4.13 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).
4.13.1 DIP Switch Summary: ACM-16AT, ACM-32A
4.13.2 Addressing ACM-16AT and ACM-32A
Set the address with rotary switches on the back of the annunciator (see Figure
4-4). 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 and the literature for the respective fire alarm
control panel for further details.
DIP
Switch 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 4.13.3
“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 3.4 “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.
