1. Product Overview
This manual provides instructions for connecting an ACM-16ATF series and
ACM-32AF series annunciators to various Fire Alarm Control Panels. Each
appendix contains instructions that are unique to a particular FACP.
General
This series provides Fire•Lite FACPs with up to 32 remote serially connected
annunciators, each with a capacity of 64 points, for a total capacity of 2048
points. Expander modules are provided for each series.
The series provides an array of LEDs to indicate, at a remote location, the
status of circuits within the system. Individual fire alarm control panels offer
different methods of identifying annunciator points:
• Sensiscan 200 and Sensiscan 2000 - Annunciator points directly
follow the circuit arrangement of modules installed in the cabinet.
• MS-9200 and MS-9600 - Annunciator points are programmable by
group.
Common system functions such as signal silence, system reset, and local
annunciation controls (local acknowledge and lamp test) are controlled
through the annunciator's integral membrane push switches.
Communication between the control panel and the modules is accomplished
over a power-limited, two-wire serial interface employing an EIA-485
communication standard. Power for the modules is provided via a separate
power-limited power loop from the control panel which is inherently
supervised by the annunciator module (loss of power results in an
communication failure at the control panel). The module can also be powered
from a power-limited and regulated remote power supply listed for fire-
protective signaling use.
