Meter (2600HD1 Systems only). The ZM-3224 features pro-

grammable 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 BB consists of the ZM-3224 plus a special I/O Interface

Module used for internal system communications. This option

is used only in 2600HD3 Systems.

Options C & CC (Two Class B TRI-Wire Zones)

These options utilize the ZM-3224 Input Module factory config-

ured to provide two independent Class B (Style B) dual input

initiating device circuits. Each detection circuit will accommodate

up to 5,000 feet (1,524m) of Protectowire Type TRI, three wire

Dual Temperature Linear Heat Detector (TRI-Wire

). This

module senses two alarm trip levels. The first level operates on a

low temperature pre-alarm input signal and the second level is

activated by a high temperature alarm signal. In addition, the

module provides an auxiliary pre-alarm output signal and an

auxiliary confirmed temperature output signal which is initiated

only after both the low temperature pre-alarm and high

temperature alarm signals have been activated. Each TRI-Wire

zone requires two Intrinsic Safety Barriers (Option G) when

installed in areas that are classified as hazardous.

Option CC consists of the ZM-3224 plus a special I/O

Interface Module used for internal system communications.

This option is used only in 2600HD3 Systems.

Protectowire Alarm Point Location Meter Scanner – Options D,

D2, D3 & D4

The 2600HD1 Control System contains a standard Protectowire

Alarm Point Location Meter which is designed to locate a heat

actuated point on the Protectowire Linear Heat Detector. A Zone

Alarm Scanner option is available for this metered system which

allows for automatic identification and display of the Protectowire

zone in alarm, as well as the alarm point distance location, while

still monitoring the remaining Protectowire zones for an alarm con-

dition. The Scanner is available for all 2600HD1 systems in the fol-

lowing configurations: 8 zones (Option D), 16 zones (Option D2),

32 zones (Option D3), and 48 zones (Option D4).

Supervisory Modules – Options E, EE, F & FF

Option E consists of the standard ZM-3224 Input Module which

has been factory configured to provide four Class B (Style B)

Supervisory Circuits that can be used to monitor any device(s)

which contains normally open contacts such as temperature moni-

tors, tamper switches, air pressure switches or fire pumps.

When a normally open supervisory switch closes initiating a super-

visory alarm, the corresponding zone’s red alarm LED indicator

becomes active along with the common trouble LED on the main

control board. The zone will remain in a supervisory alarm condi-

tion until the switch has been restored to its normal open position,

and the system alarm reset switch is activated. If an open in the

supervisory circuit occurs, the corresponding zone’s yellow trouble

ED activates along with the common trouble LED on the main

control board. These indicators will stay illuminated as long as the

trouble condition exists. The system will self-restore to its normal

standby condition once the trouble condition(s) has been cleared.

Option F utilizes the ZM-2 Input Module which has been factory

configured to provide two Class A (Style D) Supervisory Circuits.

he module’s operation is the same as that described for Option E.

Options EE and FF incorporate a special I/O Interface in conjunc-

tion with their respective ZM Series Input Modules. The I/O

Interface Module is required for internal system communications

and is used only on 2600HD3 Systems.

Intrinsically Safe Detection Circuits — Option G

The 2600HD Series can be provided with intrinsically safe Class B

(Style B) detection circuits for those areas that are classified as

hazardous. In this configuration, the voltage and current in the

detection circuits is limited to values which are incapable of causing

an explosion in a Division 1 area.

Option G consists of a shunt diode barrier which has been tested

by FM as compatible with 2600HD initiating circuits and

approved for use in Class I, II, and III, Division 1, Groups A, B, C,

D, E, F, and G hazards. When employed on two wire initiating cir-

cuits (Option B), one Option G shunt diode barrier is required for

each detection zone intended for use in a hazardous location.

When Option G is used in conjunction with TRI-Wire initiating

circuits (Option C), two barriers are required for each initiating

zone. In this configuration, the intrinsically safe TRI-Wire initiating

circuits are approved for use in hazardous locations classified Class

I, II, and III, Division 1, Groups C, D, E, F, and G.

The use of Option G requires that the system ground fault detec-

tion circuit be disabled. Only Protectowire Linear Heat Detector

and/or other non-energy storing contact initiating devices may be

used on detection circuits which employ this feature.

Solenoid Monitor and Release Modules –

Options H, HH, J & JJ

The RM-2 Series Solenoid Monitor and Release Module is

designed to operate and supervise solenoid valves or relays used for

the actuation of extinguishing systems. Release logic and activation

of each release circuit is governed by a designated detection zone or

group of zones in the 2600HD system. When the alarm signal is
