2.1 General
ACS annunciators provide NOTIFIER fire alarm control panels or network displays with remote serially connected annunciators. Arrays of
LEDs indicate, at a remote location, the status of circuits within the system. Individual fire alarm control panels offer different methods of
identifying annunciator points.
Common system functions such as signal silence, system reset, and local annunciation controls (local acknowledge and lamp test) are con-
trolled through switches on the annunciator's keypad.
Communication between the control panels or network displays and these annunciators is accomplished over a power-limited, two-wire
serial interface employing an EIA-485 communication standard. Power for these annunciators is provided via a separate power-limited
power loop from the control panel which is inherently supervised by these annunciators (loss of power results in an annunciator communica-
tion failure at the control panel). These annunciators can also be powered from a power-limited and regulated remote power supply listed for
fire-protective signaling use.
The National Standard of Canada (CAN/ULC-S527) requires that a dedicated display use yellow visual indicators to indicate the status of
supervisory inputs. The annunciators listed below are intended to be used for Canadian Supervisory Service in conjunction with
AFP-200, AFP-400, S500, S2500, and S5000 control units (subject to annunciator-panel compatibility):
•
ACM-24AT/ACM-48A and expanders: These modules provide programmable colors (red/green/yellow).
•
ACM-16AT/ACM-32A and expanders: Modules in the -16/-32 "Y" series have been designed with yellow LEDs; other colors are
also available (see Section 3.3 and Section 3.4).
The ACM-32A, AEM-32A, ACM-16AT, and AEM-16AT annunciators can not be employed for ULC Supervisory Service. See Canadian
Requirements for Supervisory Signal in NOTIFIER Document 50056.

2.1.2 ACM-24AT, ACM-48A, AEM-24AT, and AEM-48A
These annunciators provide NOTIFIER fire alarm control panels with up to 32 remote serially connected annunciators each with a capacity
of up to 96 points (subject to the limits of your control panel), for a total maximum capacity of 3,072 points. Individual fire alarm control
panels offer different methods of identifying annunciator points:
NFS-3030 and NFS2-3030 Annunciator points are completely programmable and can be employed to annunciate and manually control
common system, voice or telephone circuits. User-defined points can be defined by using VeriFire software; see your control panel manual.
AM2020, AFP1010 Annunciator points are completely programmable and can be employed to annunciate and manually control common
system, voice or telephone circuits.
NFS-320, NFS2-640, NFS-640 Annunciator points are programmable by group or by point. User-defined points can be defined by using
VeriFire software; see your control panel manual.
AFP-100, AFP-200, AFP-300, AFP-400. Annunciator points are programmable by group. User-defined points can be defined for
AFP-300/AFP-400 systems by using VeriFire software; see your control panel manual.
The Network Control Annunciator (NCA or NCA-2) and Intelligent Network Annunciator (INA) can employ these annunciators on the
EIA-485 interface. Refer to the NCA Manual, NCA-2 Manual, or INA Manual for further details.
