Preface
This manual is intended for use by the user of the Ziton ZP3 Extinguishing
Control System. It provides the information required to effectively operate the
Extinguishing Control System in all operating modes.
Limitations
Sensing Equipment Limitations
The Extinguishing Control System equipment is reliant on external detection
equipment such as detectors, call points and fire control panels in order to
activate effective fire alarms. Incorrect positioning of the detectors, limitations in
the detector itself or incorrect application can result in failure of the detection
process.
Power Faults
In the event of a mains fault the Ziton ZP Fire System can run off on board
batteries for approximately twenty four hrs depending on the loading of the
system. After this time, the Ziton ZP Fire Control System will no longer detect
fires and thus cause the Extinguishing Control System to be unable to extinguish
fires until such time as the mains power is returned.
Bells and Sirens
When the Extinguishing Control System causes an extinguishing discharge, the
appropriate fire bells and sirens sound. These could prove useless unless they
are situated in close proximity to the people they are supposed to alert.
Extinguishing System Design
The Extinguishing Control System only controls the extinguishing activating
circuits. The design of the piping nozzles extinguishing pressure etc. is the
responsibility of the extinguishing system design engineer.
Maintenance System
As with most extinguishing systems the most common cause of their malfunction
is lack of maintenance. A full maintenance plan should be carried out on a
regular basis as described under “Routine Maintenance” in Chapter 3 of this
manual (see page 27).

System Overview
Control of Fire Extinguishing Systems
The ZP Analogue Addressable Fire Detection System is ideally suited to
operating fire extinguishing systems that use an extinguishant such as foam, dry
chemical or powder to combat fires in any size area. Fire extinguishing systems
are extensively used to protect risks such as computer rooms, data storage,
transformers, electrical control rooms, file storage and, essentially, any area
where the use of water is inappropriate.
The nature of extinguishing systems imposes certain criteria upon the fire
detection and control equipment. These are needed to prevent accidental
discharge, audible alarms indicating alarm and discharge, time delays to allow
evacuation of personnel from the area, shutdown of equipment and ventilation,
and the closing of doors and shutters to prevent leakage.
The ZP Extinguishing Control System not only achieves these requirements, but
also includes the many advantages of advanced addressable analogue fire
detection.
A major feature of the system is that all functions are software controlled. All
actions carried out at the Extinguishing Control Unit, both automatic and manual,
are reported to the main ZP Fire Alarm Panel via the Addressable
communication line.

Chapter 1: Introduction
ZP3-ECU Extinguishing Control Unit User Guide 3
Extinguishing Control Unit
The Ziton ZP3-ECU Extinguishing Control Unit, see Figure 2, is designed to
connect to a ZP fire detection system, and control a fire extinguishing system. It
interfaces to the fire detectors of a ZP fire detection system, and provides secure
"coincidence connection" control of the extinguishing system.
The self-contained unit has key switches for automatic or manual selection, as
well as lock-off for maintenance. Other controls are a manual extinguishant
release, an alarm silence push-button, extinguishant hold off button and
indicators for automatic, manual, locked-off, fault, fire, extinguishant discharged
and reset status.
Outputs are provided for extinguishant release valves or actuators, audible fire
alarm sounders, separate extinguishant release sounders, visual exit signs, door
closing and shutter release. Also provided are facilities for remote manual
extinguishant release, and remote operation and status functions.
Extensive monitoring is provided for many functions, including power supply,
fuses, and operation. Field wiring is monitored for extinguishant release
valves/actuators, fire sounder, extinguishant sounder and manual extinguishant
release units.
Optional monitoring is provided for low extinguishant pressure, extinguishant
release verification, and locked/unlocked entry door status of the protected area.
The extinguishing control unit is under the control of its ZP fire control panel. It
communicates with the fire panel every two seconds, and reports the status of all
functions. A fault signal is raised at the fire panel for any out-of-normal condition,
which exists at the extinguishing control unit. The fire panel indicates the type of
fault, and where applicable, reports the condition to a building management
system. Remote status of each extinguishing control unit -automatic, manual,
fault, locked-off, or extinguishant discharged can be displayed at the ZP fire
control panel without additional wiring.
Each extinguishing control unit operates one fire extinguishing system. Any
number of extinguishing control units may be used on a ZP fire detection system,
with each unit requiring two system addresses. The system is field programmable,
with functions such as detector cross-mapping, automatic extinguishant release
delay, selection of delay/no delay for manual extinguishant release, and output
relay control being fully configurable.

Extinguishing Status Unit
The Ziton ZP3-ECUS Extinguishing Status Unit, see Figure 3, is designed to
connect to a ZP3-ECU Extinguishing Control Unit.
The Extinguishing Status Unit has key switches to enable remote control of the
Extinguishing Control Unit for automatic or manual selection, as well as lock-off
for maintenance. Other controls are manual extinguishant release via the
callpoint, alarm silence push button, as well as an extinguishant hold off more
time button. Indicators mimic those on the Extinguishing Control Unit for
automatic, manual, locked-off, extinguishant discharged and reset status.
Manual extinguishant release facilities are monitored from one Status Unit to
another with an end of line resistor connected at the unit furthest from the
Extinguishing Control Unit. This resistor can be connected by means of a link.
Up to ten Extinguishing Status Units and/or Repeater Units may be attached to
any one Extinguishing Control Unit.

Extinguishing Repeater Units
The ZP3-ECUR Extinguishing Repeater unit, see Figure 4, connects to a ZP3-
ECU Extinguishing Control unit in the same way as an Extinguishing Status unit.
However, the repeater unit only mimics the indications of the control unit: it does
not enable remote control of the unit.

Extinguishing Control Door Monitor Board
The Extinguishing Control Door Monitor Board is an optional board, which fits
"piggy-back" on the Extinguishing Control Unit Main Control Board. The door
monitor board gives an alarm when an extinguishant protected room is left in an
automatic discharge condition while personnel are still in the room, or, if left in a
manual discharge condition when the room is unoccupied. A switch connected to
the entrance lock detects whether or not the room is occupied.
