Annunciator Control Systems

General

The ONYX® Series ACS Annunciators provide a modular line

of products for annunciation and control of the NOTIFIER

ONYX® Series Intelligent Fire Alarm Control Panels, Network

Control Annunciators, and NOTIFIER’s legacy addressable

panels. The ACS line provides arrays of LEDs to indicate point

status and, in some versions, switches to control the state of

output circuits. These ACS units use a serial interface and may

be located at distances of up to 6,000 feet (1,828.8 meters)

from the panel.

Features

• Speaker control mode for use with XPIQ and the following

panels: NFS2-3030, NFS2-640, NFS-320(C) and NFS-

320SYS. Enables the ACS to control operation of groups of

multi-channels mapped to groups of multi-speakers.

• Compatible with existing annunciators.
• Color-programmable LEDs.
• On-board end-of-line resistors can be enabled/disabled by

setting a switch.

• Alarm/Circuit On and Trouble LED per-point thxoption or

more dense Alarm-only option.

• Touch-pad control switch option for remote control of sys-

tem relays; or silence, reset, and evacuate.

• LEDs may be programmed to display status of indicating

circuits or control relays as well as system status condi-

tions.

• System Trouble LED indicator.
• On-Line/Power LED indicator.
• Alarm and trouble resound with flash of new conditions.
• Local sounder for both alarm and trouble conditions with

silence/acknowledge button (program options).

• May be powered by 24 VDC from the panel or by remote

power supplies.

• Microprocessor-controlled electronics, fully supervised.
• Slip-in custom labels, lettered with standard typewriter or

LabelEase program.

• Plug-in terminal blocks for ease of installation and service.

Construction

The ACS modules are provided in two basic controller mod-

ules, each with its expander module. The ACM-24AT provides

24 annunciation and control points per module, each with a

red, green, or yellow Alarm/Circuit On LED, a yellow Trouble

LED, and a touch-key switch. The ACM-48A provides 48

annunciation points per module, each with a red, green, or yel-

low Alarm/Circuit On LED (for annunciating control relays, the

LED indicates ON/OFF).
On the ACM-24AT, each LED point is individually color-pro-

grammable. On ACM-48A, each column of 24 LED points can

be color-configured using a DIP switch.
Temperature and humidity ranges: This system meets

NFPA requirements for operation at 0°C to 49°C (32°F to

120°F); and at a relative humidity (noncondensing) of 85% at

30°C (86°F) per NFPA, and 93% ± 2% at 32°C ± 2°C (89.6°F ±

1.1°F) per ULC. However, the useful life of the system’s

standby batteries and the electronic components may be

adversely affected by extreme temperature ranges and humid-

ity. Therefore, it is recommended that this system and all

peripherals be installed in an environment with a nominal room

temperature of 15°C to 27°C (60°F to 80°F).

Installation

The ACS Series annunciator and control subsystems use

modular hardware assemblies which allow the custom configu-

ration of the annunciator panel to fit the individual job require-

ments.
Standard backboxes and mounting hardware schemes, includ-

ing special remote cabinets, allow the annunciators to be con-

structed and configured with other system components.
When used with the NFS2-3030, NFS2-640, NFS-320 or leg-

acy panels, the ACS modules can be used for manual selec-

tion of speaker and telephone circuits. In this application, they

are typically mounted in the main control near the microphone

and telephone handset.
For remote annunciation applications, the modules are typi-

cally mounted in special ABF or ABS boxes. Control switch key

locks (AKS-1B) are available.
Communication between the ACS Series annunciators and the

host Fire Alarm Control Panel is made through an EIA-485

multi-drop loop, eliminating the need for costly wiring

schemes. Four wires are required, two for the EIA-485 com-

munications (twisted pair), and two for 24 VDC regulated

power.
Retrofit of ACS Series annunciators into existing systems is

easily accomplished. Software may require upgrading, and

some legacy panels may require an interface board.
All field-wiring terminations use removable, compression-type

terminal blocks for ease of installation, wiring, and circuit test-

ing.
