System Control Units

The core system is available in three distinct configurations:

• 2600HD1

—

The standard system control unit has been desig-

nated the 2600HD1. This model consists of an MB-97 Series

Main Control Board, associated power supply and standard

Protectowire Alarm Point Location Meter. The meter will display

the linear distance in feet or meters from the start of the Detector

ortion of the zone to the heat actuated point on the

Protectowire Linear Heat Detector.

• 2600HD2

— A non-metered version of the standard control unit,

model 2600HD2 is available for those applications which do not

require the use of a Protectowire Alarm Point Location Meter.

Should system requirements change after installation, the

2600HD2 has been designed to accommodate easy field installa-

tion of an optional Protectowire Alarm Point Location Meter

without the need to replace the system’s original modules.

• 2600HD3

— The 2600HD3 configuration consists of the

MB-97 Series Main Control Board, associated power supply, and

PCLC based operator interface (OI) touch screen display panel.

This enhanced system control unit provides a Protectowire Alarm

Point Location Meter function with automatic alarm scanning,

data history logging, expanded communication capabilities using

RS232/422/485 serial ports, and when properly configured,

graphic annunciation of the protected hazard area.

System Control Unit Features

Each system control unit contains an MB-97 main board which

provides user operated control switches, complete power

management, adjustable battery charger with monitor, ground fault

detection, lamp test, one Class A/B (Style Z or Y) general alarm

notification appliance circuit, one Class A/B (Style Z or Y) pro-

grammable auxiliary alarm notification appliance circuit and trouble

silence resound timer.

Twelve (12) system status LED indicators are mounted on the

MB-97 main board. A green Power On LED, a red General Alarm

LED, a red Auxiliary Alarm LED, one each yellow Common

Trouble LED, Trouble Silence LED, Ground Fault LED, General

Alarm Circuit Open LED, General Alarm Circuit Short LED,

Auxiliary Alarm Circuit Open LED, Auxiliary Alarm Circuit Short

LED, Battery Out LED and Battery Low LED. On board system

controls consist of four slide switches which activate System Alarm

Test, System Reset, Alarm/Trouble Silence and Lamp Test func-

tions.

All system alarm, trouble, and supervisory indicators are 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 individ-

ual control and detection modules have

on-board LED indicators which dupli-

ate the external LED indicators to assist

in identifying various alarm, trouble or

off normal conditions once the control

panel door has been opened.

The 2600HD Series Control Unit has

been designed to provide maximum

ower management flexibility, and is

offered in three standard power configu-

rations. Each configuration is identified

by a unique ordering code which desig-

nates the system’s input operating voltage

and back-up power source:

GC1 — 120 VAC, 50/60 Hz. Input

with Gel Cell (Sealed Lead Acid)

Battery Back-up.

GC2 — 240 VAC, 50/60 Hz. Input with Gel Cell (Sealed Lead

Acid) Battery Back-up.

UC1 — Universal Primary and Back-up Power Input.

Uninterruptible Second Source Back-up Power required.

The UC1 Universal Power Input option utilizes highly efficient

switching power supplies for both system primary and secondary

back-up power input. Each power supply is capable of operating on

input voltage ranges of 120 - 240 VAC or 120 - 250 VDC. In this

configuration, emergency back-up batteries are not used in the

system and the standard MB-97 main board is replaced by the

MB-97-UC1 which does not contain battery charging or monitoring

capabilities. All other functional system controls remain the same.

System Options

Initiating Device Modules – Options A, AA, B, BB, C & CC

The 2600HD Series Control Panel utilizes two distinct input mod-

ules (ZM-2/ZM-3224) for all alarm initiating devices. Both mod-

ules have been designed to operate up to 5,000 feet (1,524m) of

Protectowire Linear Heat Detector as well as other types of initiat-

ing devices such as smoke and flame detectors, water flow switches,

manual pull stations and spot heat detectors.

Options A & AA (Two Class A Detection Zones)

Option A consists of the ZM-2 Input Module configured to pro-

vide two independent Class A (Style D) two wire initiating device

circuits. Each initiating circuit is equipped with one red alarm

LED, one yellow trouble LED and a push button switch for

manual operation of the Protectowire Alarm Point Location

Meter (2600HD1 Systems only). The ZM-2 features program-

mable alarm output signaling, auxiliary alarm and trouble outputs

by zone for operation of other devices such as relays, and on

board cross-zoning circuit for extinguishing applications.

Option AA consists of the ZM-2 plus a special I/O Interface

Module. This option is used only in 2600HD3 Systems.

Options A and AA may not be used with Intrinsic Safety

Barriers (Option G).

Options B & BB (Four Class B Detection Zones)

The ZM-3224 Input Module as utilized in Options B and BB,

provides four independent Class B (Style B) two wire initiating

device circuits. Each initiating circuit is equipped with one red

alarm LED, one yellow trouble LED and a push-button switch

for manual operation of the Protectowire Alarm Point Location

PCLC Graphic Display (2600HD3)
