DESCRIPTION

The fire prevention unit is made up of a Vertical Turbine type service pump driven by a standardised electric motor and a compensation submersible electric pump and consists of two modules.The first will be positioned above the water storage tank and consists of a base on which they are mounted:

  • One standardised electric motor, capable of providing maximum power for any load condition, is connected to the main pump control unit.
  • Two delivery pillars for the pumps including all the accessories required are in accordance with standard UNI-EN 12845.
  • An interconnection collector
  • An iron framework on which the electrical control panels for the two pumps are installed.

The second consists of the actual pumping parts which will be immersed in the water storage tank and hydraulically and mechanically connected to the delivery pillars located on the base of the first module.  The service pump, equipped with a foot valve, will be connected by means of a shaft line that acts as a transmission shaft and delivery pipe at the same time.

COMPONENT BASE

A thick base, made of press-folded and galvanised steel, equipped with holes for the installation of the axis line.  Supplied with levelling and adjustment elements, support truss for electrical panels..

SERVICE PUMP

Submersible centrifugal service pump with a vertical axis of the axial-flow type, multi-impeller, manufactured with cast-iron stage supports and impellers, complete with foot valve with anti-vortex plate and suction strainer.  Connection to the standardised electric motor via the control unit and axis line. The motor is sized to provide the maximum power consumption of the pump according to ISO 3046.

PRESSURE COLUMN SERVICE PUMP

It mainly consist of:

  • Concentric reduction to keep the water speed within 6 m/sec, (as indicated by the standard).
  • Recirculation device (2% of flow rate) (par. 10.5)
  • Pump pressure switch in operation
  • Anti-vibration joint
  • Inspectable check valve
  • Pressure switch test circuit with two starting pressure switches (par.10.7.5.1) and glycerine bath pressure gauge
  • Wafer exclusion valve
  • Delivery manifold - Equipped with pilot pump connection, flow meter connection and pipework for technical room sprinkler kit (accessory)

COMPENSATION PUMP

The compensation pump is submersible, which can be cooled by, pumped liquid or by a 4” multi-impeller which is cooled by its surrounding liquid.  It is connected to the main pump manifold via a discharge pillar on which the following components are installed:

  • 01 Non-return valve
  • 01 shut-off valve
  • 01 pressure switch
  • 01 pressure gauge
  • 01 20L autoclave vessel for maximum operating pressure of 16 bar.
  • 01 Control panel in compliance with EN 12845 standards. In units with a service pump having a delivery head of less than 8 bar, the above-described components could be replaced by Pressoflussostat specifically designed for pumps installed on fire prevention units.

The compensation pump starts and stops automatically when the pressure is restored.

Electric pump control panel in compliance with UNI-EN 12845 standards with integrated SUPERVISION remote control and telemonitoring device.

The main electric pump panel is constructed with certified components assembled inside a metal box protected by RAL 3000 paint powders based on electrostatically applied synthetic resins, which are highly resistant to corrosion.  The system is managed by a highly reliable and robust electronic control unit that fully meets the requirements of EN 12845.  All electrical measurements and motor controls are shown on a backlit display; the RS232 socket allows the connection of a GSM modem for communication via mobile phone.
The standard version is certified for IP 54 protection, IP 55 and IP 56 are manufactured on request.

Inside the switchboard is the brand new SUPERVISION, high-tech remote control and telemonitoring device, specially designed to remotely control and monitor all the functions of the fire prevention unit via the web in real-time, using a PC, Smartphone or Tablet.  This allows the user to take advantage of the numerous services offered by the dedicated portal, from simple alarm signalling to, useful management of periodic maintenance; from useful consultation on the state of efficiency of the equipment to, keeping a record of all the important events that have occurred during the life of the pumping unit.

STANDARD CONFIGURATION

It is possible to switch the unit to UNI 10779 operation, with a programmable stop time from a digital display.

Inside the electrical panel, there is a terminal board that allows the transfer of the main (four) alarms provided for by the law that signal the presence of malfunctions of the pumping unit or its intervention due to the presence of fire, to a special apparatus equipped with visual (lamps or LEDs) and acoustic (siren) warnings, placed in a supervised environment. The connection between the two systems is made via electrical cables.  Other systems using the GSM network, with an appropriate SIM card, can transfer the same signals to a fixed or mobile telephone device.

CLIMATEC, on the other hand, integrates the components of its switchboards with a device called Supervision, which makes it possible to check the status of the fire prevention unit from anywhere in the world, even when it is not in use. 

Supervision is a GPRS communication gateway device that integrates with a specific technological platform (portal) designed to extend the ability to control and supervise the system via the Internet using a Web browser on PC/MACs, Smartphones or Tablets. It allows constant monitoring, even in groups, of all the main parameters relating to the operating status of a fire prevention unit built in accordance with UNI-EN 12845, and of all the other accessory functions not provided for in the standard.  Supervision retrieves, at regular and programmable intervals, all the information in the switchboard control units and transmits it to the portal cloud, making it immediately available for consultation by the user.  Since the connection to the platform is two-way, it is possible for the user to get information directly from the unit, especially when malfunctions occur or problems arise that trigger the alarm signals.  In this case, by means of prior setting up, it is possible for these signals to be sent by SMS and/or email also to intervention centres such as Assistance Centres, Fire Brigade, Police…

The system makes it possible to schedule the periodic maintenance operations required by the law and to activate remote tests; The portal acts as a data logger for the whole system, recording the main events that have occurred in the unit and providing a reliable report on the history of faults and the correct execution of weekly and periodic tests.  These reports can be provided to the supervisory bodies to demonstrate the accuracy of the operations carried out or the exact moment when an event occurred (e.g. fire).

Main parameters of which Supervision allows remote monitoring for electric pumps with panels built to EN 12845 standards.

  • Voltage status / Voltage failure
  • Pump Start Test / Failure to Start
  • ECU efficiency / ECU memory error
  • Pump running
  • Pressure switch call
