Appendix G: System 5000 Systems: ACM-16AT and ACM-32A Only (UL 8th)

G.1 Capabilities
When installed with a System 5000, the ACS can annunciate the status of initiating and notification circuits, relays, and several system con-
trol functions. Each annunciator LED is automatically assigned to one and only one system point.
• Circuits
– IZM-8 Initiating Device Circuits (alarm and trouble)
– ICM-4/ICE-4 Notification Appliance Circuits (trouble)*
– CRM-4/CRE-4 Control Relays (trouble)*
– TCM-2 circuits (trouble)*
– TCM-4 circuits (trouble)*
– VCM-4/DCM-4 circuits (trouble)*
– AIM-200 zones (alarm and trouble)
*Note: Indication of output circuit activation can be obtained by programming the control panel for "OUTPUT STATUS."
• System Controls
– Acknowledge
– Signal Silence
– System Reset
Activate Notification Circuits 1 and 2, the Remote Signaling Municipal Tie circuit, and the Alarm Relay.
G.2 Connecting the EIA-485 Circuit
Communication between the control panel and the Annunciator Control System is accomplished over a two-wire EIA-485 serial interface.
This communication circuit is supervised by the System. To operate the ACS, the control panel must be Revision D or greater. The revision
level of the control panel is marked on a label affixed to the upper board. Additionally, the system must be operating under control panel soft-
ware with U4 ROM part number 73085 or higher.
Loss of communication results in "System Trouble" and "Module Failure" indications at the control panel.
NOTE: "System Trouble" and "Module Failure" will also occur if the normally closed supervisory path between TB1 Terminals 6 and 7 on the
annunciator is opened (or the jumper has not been installed).
The EIA-485 circuit that drives the annunciator must be power-limited and connected as illustrated in Figure G.1.
• Power-limited and supervised.
• 6,000 feet maximum distance (@16 AWG) between the control panel and the furthest annunciator.
• Use twisted pair cable with a characteristic impedance of approximately 120 ohms.
• EIA-485 circuit rated 5.5 VDC max., 60 mA max.
