Installation, Configuration, and Programming
Setting Address and DIP Switches: ACM-24AT, ACM-48A
5.12 Setting Address and DIP Switches: ACM-24AT, ACM-48A
Annunciator switch settings will vary according to the requirements of your control panel (see this manual’s appendix section).
5.12.1 DIP Switch Summary: ACM-24AT, ACM-48A
To locate these switches on the back of the annunciator, refer to Figure 5.1 and Figure 5.2. To set a DIP switch “ON”, push it towards the
green circuit board.
5.12.2 Addressing ACM-24AT and ACM-48A
Set the address with rotary switches SW27 and SW26 on the back of the annunciator. Turn the
arrow with a small flat-head until it points to the correct digit.
You can connect up to 32 devices (such as ACMs, LDMs, and AFMs) to the control panel
using up to 32 unique addresses. Only one device per address can answer back.
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 Con-
trol System at the same annunciator address 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.
5.12.3 Configuring Number of Expander Modules
Indicate the number of expanders connected to each ACM-24AT/ACM-48A by setting DIP switch SW28 as shown in Table 5.1.
5.12.4 Speaker Control Mode
ACM-24AT boards provide a Speaker Control Mode for use with XPIQ or control modules. This is available for the following panels:
AFP-300/AFP-400, NFS-640, NFS-3030, NFS2-3030, NCA, NCA-2, and AM2020/AFP1010.
Note:
The XPIQ can only support up to four
channels.
DIP Switch
Function
SW32-1
Turn “ON” for Program mode. Used to cycle LED colors for annunciator points on the ACM-24AT and all AEM-24ATs connected
to it. While in this mode, communication with panel is broken and interrupt routines are disabled.
Turn “OFF” for normal operating mode.
SW32-2,
SW32-3,
SW32-4
Configures Speaker Control Mode; see Section 5.12.4, “Speaker Control Mode” for more details.
SW28-1
Turn “ON” for Manual override of control relays: When manual override button is pressed, CBE or CCBE will be inhibited. (Not
supported by all control panels; see appropriate appendix)
Turn “OFF” for normal operating mode
SW28-2,
SW28-3
Specifies the number of expanders installed; see Section 5.12.3, “Configuring Number of Expander Modules”.
SW28-4
Not used; set to OFF
SW28-5
Turn “ON” to set annunciator as Receive Only: Duplicates another annunciator operating at the same address; see Section 4.4,
“Receive/Transmit and Receive Only Configuration”
Turn “OFF” for normal operating mode (receive/transmit)
SW28-6
Turn “ON” to disable piezo.
Turn “OFF” to leave piezo in normal operating mode.
SW28-7
Turn “ON” to enable Switch inhibit: Point-control switches cannot execute system control functions.
Turn “OFF” for normal operating mode.
SW28-8
Turn “ON” for Flash inhibit: Disables flashing LEDs and prohibits piezo from sounding.
Turn “OFF” for normal operating mode.
SW30,
SW31
Sets LED colors on ACM-48A; see Section 5.15.2, “Selecting LED Colors: ACM-48A & AEM-48A”
SW25,
SW26
Sets LED colors on AEM-48A; see Section 5.15.2, “Selecting LED Colors: ACM-48A & AEM-48A”
