FireSet-XXX-XXX-XXX/XXX D

Pressure-boosting pump system with fully automatic single-pump compact unit for firefighting according to NPFA standards and with UL and FM certifications, consisting of: 1 pump with a horizontal baseplate - pump with split housing - with spacer coupling, electric or diesel motor and 1 pump with a switchgear fixed to a robust support structure. Model E for the electric motor and D for the diesel motor, both equipped with a Tornatech controller, solid structure constructed from special shapes with hooks for facilitating and securing transport, a special baseplate option for the diesel motor designed for intaking a large volume of concrete, significantly reducing vibration transfer and increasing its reliability and service life, a circuit with dual pressure switch, pressure gauge, non-return valve, valve (secured against unauthorised operation) for both the main and standby pump for an automatic start. The cables are concealed in the construction and protected against bumps and cuts. Standard-equipped with an air vent valve installed directly on the main pump housing. Only for diesel models: Motor cooling with water/water-heat exchanger, fuel tank with level sensor and sufficient volume for 8 hours’ operational autonomy and 2 batteries on the baseplate and battery charging device in the FireSet switchgear.

Switchgear for fire-extinguishing systems according to the NFPA20 provisions. FM Global-certified (class 1321/1323). UL-certified (UL218 and CSA C22.2 no. 14).

Switchgear integrated in IP54 steel sheeting housing. Very high-quality control and very easy operation via the “WiZiTouch” controller with 7" LCD display, uncomplicated menu navigation with a simple menu, touchscreen and push buttons for quickly setting parameters. Ready-for-communication controller monitoring and detection systems.

The pump system has been wired ready for connection and mounted on the base frame.

Inlet pressure

When designing the system configuration, the maximum inlet pressure must be considered (see technical data). The maximum permissible inlet pressure is the difference between the system’s maximum operating pressure and the maximum delivery head of the pump at Q = 0.

A pressure-boosting system installed under suction conditions is not permissible according to the NFPA standard. It must have a positive suction head.

Volume flow: Configuration of the system up to 3000 gpm (681 m³/h – 189 l/s) per main pump.

Operation

The operating logic for the fire-extinguishing system is based on the calibration of the pressure transducer for starting the pump.

The system maintains constant pressure by means of the optional jockey pump with automatic starting and deactivation via a pressure switch, which is dimensioned in such a way that it does not supply an individual sprinkler with any current or any pressure, thereby preventing the main pump from starting. In the event of a low pressure value conditional on water requirements, which was not compensated by a jockey pump, the main pump starts. The pump starts automatically and can be switched off manually using the switch on the front side of the control panel.

Function description:

Wilo FireSet Control D control devices can be used to control pumps with a diesel motor, sensors for pump management and the level of information. The controller is controlled via a microprocessor with “Soft PLC”, serving to control and regulate all required functions of the pressure-boosting pump system for firefighting according to the provisions of NFPA 20 for testing purposes and in actual operation of the sprinkler system.

The operating logic for the fire-extinguishing system is based on the calibration of the pressure transducer for starting the pump.

If a large amount of water is requested due to the opening of one or more circuits or due to a defective sprinkler, the pressure in the system decreases. In this case, the starting of the main pump is activated by the FireSet controller.

As soon as the sprinkler circuit or gate valve, via which the sprinkler heads are supplied, is closed, pressure is built up in the system. Then the stop buttons on the control panel must be pressed to stop the main and standby pump.
