Introduction

The ACR-1600HD Series is specifically designed for industrial special hazard applications, which demand high reliability and customized system operation. Unlike competitive systems which are often limited in scope, the ACR-1600HD Series is custom designed to each customer’s specific requirements. Special requirements, such as custom system operating logic, outdoor and hazardous installation environments or special operating input voltages can be provided to meet any fire defense need.

System Features

All system alarm, trouble, and supervisory indications are provided by reliable LED indicators mounted on the front of the enclosure behind a sealed window, which has been specially designed to maintain the integrity of the enclosure’s NEMA rating. In addition, most individual control or detection modules have on board LED indicators which duplicate the external visual indicators to assist in identifying various alarm, trouble or off normal conditions once the control panel door has been opened.

Five system status indicators are mounted on the main control board. A yellow power supply trouble/backup on LED, a yellow detection circuit trouble LED, a yellow alarm (audible) circuit trouble LED, a yellow charger out LED, and a red alarm test LED.

System detection and supervisory modules provide individual switches for alarm reset, alarm silence/zone bypass, and zone alarm test.

Solenoid Monitor and

Release Module

(Option N).

Solenoid Monitor and Release Circuit

(Option N)

The SM-1001 Series Solenoid Monitor and Release Module (Option N) is designed to operate and supervise solenoid valves used for actuation of extinguishing systems.

Release logic and activation of the module is governed by a designated detection zone or group of zones in the ACR-1600HD Control

Panel.

The release circuit is supervised for open and shorted conditions. In the event of an open or short, the system trouble buzzer will sound, and the appropriate yellow indicating lamp(s) will illuminate. The

SM-1001 provides a solenoid disconnect switch to deactivate the module during servicing. Also provided are on board yellow diagnostic LED’s for open circuit, short circuit, solenoid out (disconnect) and trouble buzzer switch to be silenced. A red solenoid trip LED is also provided to confirm module activation as well as a set of Form

C dry trouble contacts for auxiliary field use.

The SM-1001 (Option N) has been Factory Mutual approved for the following solenoids: Skinner Model LV2LBX25; ASCO Models

T8210A107; R8210A107; 8210A107; and the Star Model D deluge valve which requires a special power supply and is provided on special order.

PWM-D

Protectowire Alarm

Point Location Meter with16 zone scanner

(Options F & Y).

PWM-D Protectowire Alarm Point

Location Meter (Option F)

Protectowire introduces “smart” detector technology to Linear Heat

Detectors. The PWM-D Meter (Option F) may be built into the ACR-

1600HD Control Panel to locate a heat actuated point on the Protectowire Linear Heat Detector. The Meter will display the distance in feet or meters from the start of the detector portion of the zone to the overheated or shorted point on the Protectowire

Linear Heat Detector.

A Zone Alarm Scanner Option for the PWM-D Meter is available which allows for automatic display of the zone number in alarm, while still monitoring the remaining zones for an overheat condition. The Scanner, which must be ordered with the PWM-D Meter option, is available in the following configurations: 8 zones (Option

X) and 16 zones (Option Y), 32 zones (Option Y2) and 48 zones

(Option Y3).

Intrinsically Safe Detection Circuits (Option W)

The ACR-1600HD control equipment can be provided with FM approved intrinsically safe detection circuits (Option W) for those areas that are classified as hazardous (National Electrical Code Class

I, II, and III, Division 1, Groups A, B, C, D, E, F and G). The voltage and current in the detection circuits will be limited to values which are incapable of causing an explosion in a Division 1 area. Protectowire Linear Heat Detector and/or other non-energy storing initiating devices may be used in these areas.

This option permits the use of the Protectowire Alarm Point Location Meter (Option F), but is not compatible with the system ground fault detection circuit (Option R).

Class B switch supervisory circuit

(Option P).

Class B Supervisory Circuits (Option P)

The ZM Series Supervisory Module (Option P) is designed to provide one Class B circuit used to monitor any device(s) which contains normally open contacts, such as temperature monitors, tamper switches, air pressure switches or fire pumps.

The module is designed so that a short on the input circuit lights a yellow supervisory lamp on the control panel door. An open in the input circuit lights a yellow trouble lamp. Both supervisory off normal and circuit trouble conditions cause a panel common trouble.

The use of Option P Supervisory Circuits is not recommended for water flow detection, since this is considered an alarm condition and

Option P is not wired into the alarm circuit structure of the panel.

Water flow detection is accomplished by utilizing additional detection zones in the basic ACR-1600HD Control Panel.

Audible Alarm Circuits

The ACR-1600HD Control Panel provides one standard Class B (NFPA

Styles W & Y) general alarm circuit which is contained on the main control board and rated for a total circuit load of 3.0 amps. A Class A

(NFPA Styles X & Z) configuration is available when Option Z is ordered.

Additional Audible Alarm Circuits may be added to the system by utilizing the AM-1600 Alarm Expander Module(s) Option S. The

AM-1600 Module may be actuated from the main system control board or by an individual zone or group of zones, and is ideal for separate annunciation of water flow alarm.

The AM-1600 Module is rated for a total circuit load of 3.0 amps max.

When the Module is used in conjunction with the main panel general alarm circuit or when multiple AM-1600’s are used, total available system power must be considered when determining the number of alarm devices which may be utilized on each circuit.

System Enclosures

The ACR-1600HD Series is provided in NEMA-12 rated enclosures which are custom sized to accommodate the exact configuration of the system ordered. NEMA-4 rated enclosures are also available

(Option K) for those systems which require protection from windblown dust and rain, and hose-directed water.

Each enclosure is provided with a gasketed window which permits viewing of all appropriate visual indicators while still maintaining the enclosure’s NEMA rating and FM Approval.

Field Expansion

The zone capacity of the basic ACR-1600HD system can be expanded after installation by utilizing a zone control extender panel. These panels contain additional zone control modules, alarm and trouble indicating lamps, and are provided in a standard NEMA-12 enclosure.

NEMA-4 rated enclosures are also available. Power for these extenders is derived from the main ACR-1600HD Control Panel power supply.

Custom Options

Because the ACR-1600HD is custom designed and assembled, a wide range of unique features are available on special order from the factory. A partial list of special order features includes:

• Cross-linked flame retardant panel wiring.

• Built-in alarm indicating audible.

• Panel wire markers.

• Multi-pole heavy duty relays.

• 125VDC or 250VDC primary and/or back-up power input.
