Cheaper than buying a new model EKM

Depends on existing installation, to be assessed the entity of the required changes

Not recommended, requires high cost interventions for new materials and labour

Interventions typically required by the update:

A mechanical intervention on the monitor (mechanical modification of one or more parts, replacing or adding components)

B electrical changes on the monitor (JB modification or replacement, wiring of new components)

C mechanical intervention on the electrical panel (drilling, add / remove buttons and indicators)

D intervention on the electrical panel (add / remove electrical or electronic components, new wiring)

E additional wiring between the control panel and monitors (likely to add additional wires to existing installation)

F software update of the PLC or other electronic components of the control panel This pattern is indicative, the cost impact of each update is roughly calculated, taking into account the average cost

of the materials used for the update (mechanical and electronic components) and an estimated count of the hours of

labour needed to make changes.

For a more detailed economic evaluation is always recommended to contact KCA, providing details about the existing

installation in the field, and any special requests of the customer to consider being updated.

This scheme is valid only for updates on panels IP55, for Atex installations a new control panel is mandatory, no

modification on existing equipment is allowed.

SECTION C •

Electrical control panels

for safe areas

C.1


GENERAL INFO

A control panel is always required to correctly operate one or more monitor. Inside every

control panel are installed all the electro-mechanical components useful for movement as

well as the needed electronics in case of monitors with some level of automation.

Each panel is normally designed to accept one or more SPDT contact coming from an

external device (normally installed by customer) that act as a trigger for alarm detection.

In case of monitors with automated features, under particular configuration, this contact

starts the automated routines.

Every control panel has a minimum degree of ingress protection IP55, that allows it to be

installed either indoor or outdoor. When installed outdoor, it is recommended to have a

roof on top of it, mainly to avoid paint discoloration or other cosmetic defect.

Standard safety equipment on all panels: emergency mushroom pushbutton, power on

indicator, and general fault indicator for each monitor.

Each indicator provides a command or identification plate in Italian or English.

These models of ECP are suitable only for safe areas: see Section D for control panels

certified to be installed in Atex environment.

C.2



ECP - m X n - v - SA

m Number of controllable monitors on the same panel

One panel can control multiple monitors, recommended a maximum of 6 monitors.

n Number of independent movements per each monitor

Are considered independent movements

• Vertical movement (up / down)

• Horizontal movement (left / right)

• Control valve (either type solenoid or MOV electric actuator)

• EFX motion nozzle (jet / fog, if present)

v Monitor version

Identifies the different types and levels of automation.

Monitor version must match same version code of monitor sold in combination, as

described in Section B.

SA Monitor electrical classification



(see Section D)

TO BE DEFINED

Example code:

ECP-2X3-I2-SA Electric panel for controlling 2 monitors of type I2 (horizontal oscillation standard), 3 movements (horizontal +

vertical + valve), installed in safe area

NOTE: The ECP coding is referred to a standard control panel shape defined "bookstand type". Upon request it is

possible to have the same level of control in a panel "cabinet type": size, price and feasibility of these configurations

are provided in an out-of-standard quotation.

Cheaper than buying a new model EKM

Depends on existing installation, to be assessed the entity of the required changes

Not recommended, requires high cost interventions for new materials and labour

Interventions typically required by the update :

A mechanical intervention on the monitor ( mechanical modification of one or more parts , replacing or adding components )

B electrical changes on the monitor (JB modification or replacement , wiring of new components)

C mechanical intervention on the electrical panel (drilling, add / remove buttons and indicators)

D intervention on the electrical panel (add / remove electrical or electronic components, new wiring)

E additional wiring between the control panel and monitors (likely to add additional wires to existing installation )

F software update of the PLC or other electronic components of the control panel

This pattern is indicative, the cost impact of each update is roughly calculated, taking into account the average cost

of the materials used for the update (mechanical and electronic components) and an estimated count of the hours of

labour needed to make changes.

For a more detailed economic evaluation is always recommended to contact KCA, providing details about the existing

installation in the field, and any special requests of the customer to consider being updated.

This scheme is valid only for updates on panels IP55, for Atex installations a new control panel is mandatory, no

modification on existing equipment is allowed.

GENERAL INFO

A control panel is always required to correctly operate one or more monitors. Inside every control

panel are installed all the electro-mechanical components useful for movement as well as the

needed electronics in case of monitors with some level of automation.

Standard material is forged aluminum alloy: it is possible to have on request a stainless steel

enclosure, but normally this type of metal boxes have a lower degree of explosion protection.

Each panel is normally designed to accept one or more SPDT contact coming from an external

device (normally installed by customer) that act as a trigger for alarm detection. In case of

monitors with automated features, under particular configuration, this contact starts the

automated routines.

Every control panel has a minimum degree of ingress protection IP55, that allows it to be

installed either indoor or outdoor. When installed outdoor, it is recommended to have a roof on

top of it, mainly to avoid paint discoloration or other cosmetic defects.

Each panel is also classified as per Atex standards, refer to each panel description for more

details.

Standard safety equipment on all panels: emergency mushroom pushbutton, power on indicator,

and general fault indicator for each monitor.

Standard configuration uses a set of button for all commands, including up/down/left/right

movement. Joysticks are available as option.

Each indicator provides a command or identification plate in Italian or English.

These models of ECP are suitable only for Atex explosive classified areas: see Section C for

control panels certified to be installed in non-Atex (safe area) environment.

NOTE: for exact dimensioning of request, it is very important that customer specifies the

exact Atex classification of area where panel will be installed, to match exact requirement

SECTION G •

System integration

G.1


Advanced monitors equipped with PLC logics inside control panel can be managed in

more complex ways and fully integrated into a wider system.

Typical examples involve the control panel sending inputs to a centralized control

room, when in a big installation it is required a higher level of monitoring and

diagnostics in case of critical failures.

Standard PLC can be equipped with a series of extensions that can expand the

capabilities of a local monitor(s) system without the need of a centralized control room,

and virtually allowing a wider range of possibilities.

Here is a brief overview of some of the most interesting features.

Any solution like the ones presented are studied and developed together with customer

and tailored on their needs, this chapter is only intended to suggest some of the

possibilities that can be engineered.

G.2


Complex matrix logics for auto cycles

Picture purely indicative touch screen is fully customizable upon customer needs

Combining several monitors and an array of fire detections that can cover different locations, a

system can be built including a complex matrix of logics and priorities.

In the system shown here, every detection can trigger some of the monitors near the detection

itself, and for each monitor an appropriate automatic cycle is activated.

PLC logics are able also to assign priorities when more than one detection is triggered at the

same time to concentrate effort on most critical areas. Similar priority logics can also control the

max number of monitors operating at the same time, to avoid water outages and ensuring

optimal performances.

LCD touch panel can show in real time the status of each detection, simulate an alarm and

eventually show if a monitor is not operating properly.

All these information can be also sent to a remote control room for additional control and

diagnostics.

Such systems can reduce significantly the total number of installed devices, lowering both initial

investment and costs related to periodic maintenance of devices.

This system is in principle scalable to any number of monitor and any degree of complexity of the

entire system, can be configured in different levels or sub-sets depending customer needs.

G.3


Optical fiber and Profibus double

loop interconnections

Picture purely indicative, to be developed during investigation phase

A set of multiple monitors can be inter-connected each other with a proper local network, that

can be conveniently built using ProfiBus connection or optical fibers (either plastic or glass core).

A double loop interconnection is effective especially when additional measures are required to

grant full operativity on the system: even if a catastrophic event occurs on one of the segments

interrupting that path, all the devices are still reachable and controllable, the total flow of

commands and information are preserved.

G.4


In presence of power supplies located near monitors, the system is able also to lower significantly

the cost of the global installation: less cables to be routed through the plant, less maintenance

needed and the responsiveness of entire system is well preserved.

Especially when big distances are involved (up to 10 km and more), optical fiber solution is fast,

reliable and requires limited equipment.

Optical fiber based Profibus copper cable based

Long distance without repeaters (10+

km)

Repeaters needed every approx. 300 mt

Higher cost of fibers compared to

Profibus

Profibus cable less expensive than fiber

Installation cost depends also on layout:

long bend radius required etc

Easier installation, similar to building an

Ethernet cabled network

Cables shielded from any external

interference (magnetic, thermal etc)

Cables shielded from any external

interference (magnetic, thermal etc)

Need of OLM optical-electrical

converters at every segment end

Integrated protocol in each PLC, no

need for converters

Every request is to be evaluated for feasibility and cost impact upon receiving offer requests,

based on specs and plans provided by customer.

G.5


Remote monitoring, diagnostics and

control

Picture is only an example to show possible applications

PLC expansions can add online connectivity to the system, introducing a set of features based on

web interfaces and thus accessible to every person with a standard PC connected to a properly

configured network.

This additional remote interface is intended mainly to investigate the status of the system, for

remote assistance and diagnostics, or to know in real time the status of each device that the PLC

is controlling or only monitoring.

Additionally an active control can also be granted to the devices, leaving customer the ability to

activate an alarm, start an auto cycle or stop a device that is currently running.

Type of interface, level of access and other restrictions can be obtained by giving different access

privileges based on a user/password method, allowing only authorized persons to operate

remotely on the installed devices.

If customer has several systems in different places, each ECP is capable of this and in principle a

network of installed and owned system can be done, to facilitate a global maintenance service.

IP protection

classification

AA.1


General information All electrical equipment (motors, sensors, enclosures, pushbuttons etc) is always identified by

what is called an Ingress Protection (abbreviated in IP) level.

This declaration completes all the usual electrical characteristics of every equipment, and

identifies the resistance offered by a component to the ingress of external bodies, both solids and

liquids.

IP level is always identified by two numbers, as detailed in the table below:

IP m n

m n Protection against solids Protection against liquids

0 Not protected Not protected

1 Protected against objects of size above 50 mm Dripping water

2 Protected against objects of size above 12 mm Dripping water when tilted up to 15°

3 Protected against objects of size above 2.5 mm Spraying water

4 Protected against objects of size above 1 mm Splashing of water

5 Dust protected Water jets

6 Dust tight Powerful water jets

7 Immersion up to 1 m for 30 min

8 Continuous immersion beyond 1 m

Example code:

IP55 Identifies a device resistant to ingress of solid parts of dimensions typical of dust and to exposure to continuous

water jets. This code is the most commonly used for equipment than can resist when installed outdoor.

NOTES:

• If a device is composed of more electrical devices, the overall IP level of the assembly is taken as

the lowest of the individual IP levels, as a conservative measure

• Devices intended for Atex installations carry always an IP level, and additionally have a specific

code that identifies the explosive areas where they are authorized to be installed. For this

additional classification scheme, refer to Appendix B.

APPENDIX B •

Atex classification

AB.1


General information

When in presence of potentially explosive environment (e.g. fuel storage tanks, refineries, coal mining plants,

chemical plants with hydrogen or other highly flammable gases etc.), a dedicated code is used to define exactly all

the risks related when working in those areas, both for operators and for machines.

Every device used in such particular area, must be as well identified by a code that follows the same guideline: only

machines where the code matches or exceeds the safety measures stated by the area code are allowed to operate in

the area.

Those information are related to the type of explosive substances present

Atex protection level is always identified as in example detailed below:

Example code:

II 2GD Ex de IIB T4 Equipment certified to be used in surface industries, in occasional presence of explosive atmosphere both of gas and

dust types (so suitable for Zone 1 and Zone 21, but also in lower classification Zones 2 and 22), compliant to

European Atex standards.

Electrical enclosures are of explosion proof type, with an additional augmented safety to contain electrical sparks

during operation.

In presence of gas, enclosures can grant sealing from gases like Ethylene, Liquid Propane and Carbon Monoxide, as

well as all the gases of group IIA.

Its maximum surface temperature in operating condition is granted to be always below 135°C, so it is allowed to

operate in presence of all explosive atmospheres that ignite at temperatures above 136°C.

NOTES: • It is very important, during inquiry phase, that customer specifies the exact Atex classification of an Area, to match

same requirements also on electrical devices.

• Devices with a certain level of explosion protection are suitable for installations in areas of declared lower risk or

category.

• Devices intended for Atex installations carry always also an IP level, that specifies its degree of Ingress Protection. For

this coding scheme, refer to Appendix A.

Flow rate and pressure calculation

Normally all firefighting equipment have declared performances expressed as a combination of the standard

operating flow rate at a well defined pressure.

Customer desiring a different operating condition from what is normally stated in a standard datasheet must always

declare both project parameters, to dimension correctly every device.

For EKM and its discharge devices (FX, EFX, LS and the self-inducting variants), all the performance data are

expressed in liters/minute at a pressure of 7 bar, so it is convenient to revert every value to this condition with a

simple formula

QSTD = QCUS � √(PSTD/PCUS)

QSTD Standard flow rate (expressed in l/min) at 7 bar, to be calculated

QCUS Flow rate required by customer at the device, expressed in l/min

PSTD Standard pressure (expressed in bar): for a monitor and its discharge devices must be used the value of 7 bar

PCUS Pressure calculated at the device by customer, expressed in bar

Example: A customer requires a nozzle discharging 1250 l/min at 4,5 bar: using the formula we obtain

QSTD = 1250 � √(7/4,5) = 1560 l/min at 7 bar

So the best suitable nozzle should be the FX-25, with a custom adjustment in the factory to lower the flow rate from

the factory standard of 2500 l/min at 7 bar.

Same formula can be used to properly size a monitor (3” or 4” size choice), the branchpipes and all other

proportioning and discharging equipment

NOTE:

• It is very important, during inquiry phase, that customer specifies the exact flow rate and pressure

to operate the monitor and the discharge device, to avoid incorrect sizing of system
