Preface
This manual is intended for use by the ZP3-ECU Extinguishing Control System
installation and commissioning personnel. It provides the information required to
configure, install and commission the Extinguishing Control System and its
relevant equipment.
Safety Issues/Limitations
Installation Criteria
Do not attempt to install, service or operate the system until this manual has
been read and understood. Adherence to the manual recommendations ensures
a problem-free installation and long-term reliability.
System Power Supplies
During installation of the system or modification to the system, the DC power
supply and batteries should be disconnected to avoid damage to circuit.
Operating Environment
Make sure that all system components and peripheral equipment are located
within the limiting environment specified.
Power Transients
As with all electronic devices, the system is susceptible to damage by lightning
induced transients. Proper grounding reduces this susceptibility.
Physical Mounting
All electronic assemblies should be removed from cabinets prior to any drilling,
filing, reaming or punching of the enclosure. Before making modifications, verify
that they will not interfere with printed circuit board location.
Wiring
All wiring must fall within the limitations given in the wiring guide, with respect to
line resistance, line capacitance and cross talk from interfering signals.
Screw Terminals
Over tightening of screw terminals can damage threads, resulting in reduced
terminal contact pressure and difficulty with screw terminal removal.
Static Sensitive Components
Printed circuit boards contain static sensitive components. Retain loose printed
circuit boards in static suppressive packing.

ZP3-ECU Extinguishing Control Unit Installation and Commissioning Manual v
System Documentation
Comprehensive drawings of the system, signed off by the responsible engineer,
must be kept on record. The system design must take into account local codes
and requirements.
Limitations
Equipment Compatibility
The Extinguishant Cylinder release mechanism must be compatible with the
Extinguishing Control Unit activating circuit. Incompatibility can cause
malfunction.
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.
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.

Wiring Standards
All wiring must be installed in compliance with local codes, and in accordance
with the requirements of the local authority having jurisdiction.
Fire alarm systems must remain operative during the initial phase of a fire. It is
therefore important that certain wiring practices are followed, and must comply to
British Standard BS5839: Part 1: 1988: Sections 17 and 24.
All wiring must be installed to the standards laid down in Ziton wiring guide
GA322.
WARNING: The wiring connection to the extinguishant cylinder actuator is a low
impedance circuit, which can draw up to 1 A during actuation. Make sure that
wiring to the actuator is of sufficient capacity to avoid wiring resistance voltage
loss.
Wiring Connections
The following wiring connections are described:
• Extinguishing Control Unit to ZP Address Line connection
• Connections to the ZP3-ECU Extinguishing Control Unit
• Connection of ZP3-ECU Extinguishing Control Unit to ZP3-ECUS
Extinguishing Status Units
• Connection of ZP3-ECU Extinguishing Control Unit to ZP3-ECUR
Extinguishing Repeater Units.
ZP3-ECU Surge Protection
The Extinguishing Control Unit is often connected to a power source, which has
fluctuations and surges outside of the recommended operating voltage limits.
The ZP3-ECU Extinguishing Control Unit main board as shown in Figure 1
incorporates surge suppression and low voltage detection to try to compensate
for any fluctuations and surges.

Earth Connection
The Extinguishing Control Unit must be connected to a secure earth. Good wiring
practice should be followed and the earth connection should be kept as short as
possible. Earth is provided on pins 25 and 26, which makes connection to the
chassis.
Figure 3: Mounting Diagram
Mounting Instructions
The Extinguishing Control Unit main board is supplied with two screws and two
spring washers for mounting into the Extinguishing Control Unit box. The earth
lug from the wiring loom must be earthed as shown in Figure 3 to ensure the
effectiveness of the surge suppression board.
See Figure 3. Mount the Extinguishing Control Unit Main Board as follows:
1. Align the main board chassis mounting slots with the lower studs of the
Extinguishing Unit box.
2. Insert the main board into the Extinguishing Unit box so that the main board
chassis rests on the studs.
3. Insert the mounting screws, spring washers and the free earth lug of the
wiring loom, and tighten screws.
Note: Do not disassemble the circuit boards from the chassis.
Guidelines to Programming the ECU
All new protected areas MUST be wired using two ZP Loops. This is to ensure
the highest level of security available against accidental discharge of
extinguishant.

Chapter 1: System Wiring
ZP3-ECU Extinguishing Control Unit Installation and Commissioning Manual 5
The two addresses assigned to the Extinguishing Control Unit MUST be at least
TWENTY apart i.e. if ECU Loop A uses address A005 then ECU Loop B can only
utilise addresses from B025 onwards. Note that any two ZP loops of the fire
panel may be used for connecting the ECU. Any addresses may be assigned to
the devices within the protected area.
The devices in a protected area must be equally divided into two-coincidence
areas/patterns, namely CA1 and CA2.
A coincidence area may consist of a single detector or many detectors,
dependent on the size of the protected area.
Diagrams 1 to 4 shown in Figure 4 represent a plan view of protected areas with
the dotted lines encompassing detectors. The dotted lines form the two required
coincidence areas/patterns CA1 and CA2, which zig-zag across the protected
area, overlapping in certain places. It can be seen therefore that due to the
coincidence pattern a fire in any part of the protected area will be as close as
possible to both coincidence areas.
The ECU has two addresses each of which is associated to its own coincidence
area/pattern. There must be a fire condition in both coincidence areas to initialise
an extinguishant drop.
If you want to program a system on a Zone basis then the coincidence coverage
patterns will inherently become fire zones i.e. CA1 becomes fire Zone 1 and CA2
becomes fire Zone 2.
If you want to program a system on a device basis then each detector in CA1 will
be associated to the first ECU address and each detector in CA2 will be
associated with the second ECU address.
The basic programming principle is that from coincidence area 1 a fire alarm will
be mapped to the first ECU address and a fire alarm from coincidence area 2 will
be mapped to the second ECU address resulting in an extinguishing drop. The
devices MUST be programmed on a SKNS (single knock non-silencing) basis for
correct operation.
Programming examples are provided on the following pages.

1001 1005 (ECU FIRST ADDRESS) SKNS (Single knock non silencing)
1002 1005 (ECU FIRST ADDRESS) SKNS (Single knock non silencing)
1003 1005 (ECU FIRST ADDRESS) SKNS (Single knock non silencing)
2001 2025 (ECU SECOND ADDRESS) SKNS (Single knock non silencing)
2002 2025 (ECU SECOND ADDRESS) SKNS (Single knock non silencing)
2003 2025 (ECU SECOND ADDRESS) SKNS (Single knock non silencing)
The same format and rules apply for any protected area.
Additional Installation Information
Optional Door Monitor Board
Some Extinguishing Control systems are fitted with optional door lock monitor
boards to report the locked/unlocked status of the doors to the protected area.
This board is piggy-backed on top of the main board using the supplied
hardware.

Chapter 1: System Wiring

Planner and Maestro Graphics Software
When configuring Planner panel programming package, or Maestro graphics
package, for use with an Extinguishing Control Unit, the LOOP A address is
denoted by "ECU" and the LOOP B address is denoted by "LRY".
In the Maestro Graphics package, the LOOP A address reports the ECU status,
and therefore it is not necessary to allow for an icon for the "LRY" LOOP B
address.
Operation
There is a cosmetic software "bug" in the fire alarm panel. If the loop B address
of the ECU is activated before the Loop A address, the fire panel reports
"TRIGGR". The ECU is only "triggered" when both the loop A and loop B
addresses are activated by fire conditions. If the Loop A address is activated first
then the "bug" is not apparent. This "bug" in no way affects the correct operation
of the ECU.
Connection to the ZP3-ECU Extinguishing Control Unit
Terminal functions are described in the ZP3-ECM Extinguishing Control Main
Board installation sheet, document number 501-0803ZE-1-01 included in

Extinguishing Control Unit
We recommend that the Extinguishing Control Unit is located outside the
protected area in close proximity to the exit and to the extinguishant cylinders. If
this is not possible, then the above warning regarding impedance of the actuator
line must be taken into account. The control devices in the protective area, such
as sounders, are connected directly to the Extinguishing Control Unit.
WARNING: The wiring connection to the extinguishant cylinder actuator is a low
impedance circuit, which can draw up to 1 a during ACTUation. Make sure that
wiring to the actuator is of sufficient capacity to avoid wiring resistance voltage
loss.
The Extinguishing Control Unit is designed to be either surface mounted or
recessed semi-flush into a wall as shown in Figure 7.
Figure 7: Mounting Arrangements
Note: The Extinguishing Status Units and Extinguishing Repeater Units are
mounted the same way.
Installation Procedure
Install the Extinguishing Control Unit as follows:
1. Unlock and open the front panel with the key provided.
2. Disconnect the front panel by unplugging the ribbon cable connector on the
