Product Overview; General - Notifier ACS Series Installation Manual

Product Overview

Section 1 Product Overview
About This Manual. The core of this manual provides instructions for
connecting an ACS series annunciator to various fire alarm control panels
(FACPs). Each appendix contains instructions that are unique to a particular
control panel. Section 1.2 "Related Documentation" lists part numbers for
manuals of compatible equipment such as control panels.
This manual provides instructions for two sets of ACS series annunciators. Both
sets can be used in the same fire alarm system. There are four basic controller
modules, each with its own expander module:
In this manual, when the two varieties of ACS annunciator differ, the
ACM-24AT/ACM-48A annunciators are discussed first.

1.1 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 controlled 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 communication failure at the control panel). These annunciators can
also be powered from a power-limited and regulated remote power supply listed
for fire-protective signalling 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, AEM-24AT, and AEM-48A: Up to 96 points
can occupy the same address, subject to the limits of the control panel.
• ACM-16AT, ACM-32A, AEM-16AT, AEM-32A, and multi-color
variations (Section 2 "Product Overview" lists similarly numbered
models that provide different LED colors): Up to 64 points can occupy
the same address, subject to the limits of the control panel.
• 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 2.3 and Section 2.4).
