SiFire FIRST 65/200-195-22E
Pressure-boosting system as a fully automatic compact unit for firefighting purposes in accordance with EN 12845.
Consisting of a pump with horizontal base frame - EN 733 - with spacer coupling, electric motor and one switch cabinet, fixed to a robust support structure.
Model E for the electric motor, equipped with firefighting dedicated controller, solid construction made of special profiled parts with cut-outs for forklift trucks and hooks to ensure trouble-free, safe transportation.
A circuit with dual pressure switch, pressure gauge, non-return valve, valve (secured from use by unauthorized personnel) for the main pump for automatic start. Equipped with a diaphragm installed directly on the main pump housing as standard, to prevent overheating in the event of zero flow.
Control E switchgear for fire extinguishing systems according to EN 12845.
Switchgear integrated in a sheet metal enclosure in accordance with protection class IP54. Very high control quality and very simple operation due to the firefighting dedicated controller, with multi-languages screen, easy navigation with simple menu and push button plus immediate operation status with symbols. Communication-ready controller for supervising systems operations.
The system has been mounted on the base frame with wires and pipes are ready for connection.
The maximum inlet pressure must be taken into account when designing the system configuration (see Technical data). The maximum permissible inlet pressure is calculated from the maximum operating pressure of the system minus the maximum delivery head of the pump at Q = 0. For sprinkler systems in accordance with EN 12845, the water pressure should not exceed 12 bar. In sprinkler systems with a pronounced slope, in which the difference in height between the highest and lowest sprinkler is more than 45 m, the water pressure can be higher than 12 bar at the pump outlet or in the piping, provided that all of the system components are designed for this pressure level.
Installation of the pressure boosting pump under suction conditions.
For the main pump, it is necessary to install a supply tank with connection to the discharge pipe above the pump.
Up to 320 m³/h (89 l/s) system configuration for the main pump.
Switchgear/control device for fire water supply systems
Wilo-Control E (main pump with electric motor)
Fully electronic central control unit and electro-mechanical components, built in painted steel case, with protection class IP 54, control and display devices on the front door.
Features and functions:
The controller design is suitable for the performance of each motor-pump combination. The device comprises the following components:
Main switch: For switching the switchgear On/Off. (Unauthorized action in case of fire).
Display: Back lighted graphic LCD display, built into the switch cabinet door for operating and display purposes. Displays the operating data and the receptive current operating statuses of pump and the controller. The menu selection as well as the parameter input are done by push buttons on the front door.
Microprocessor: Integrated PLC logic with thresholds, counters, alarms, status; 24 VAC auxiliary power supply; advanced I/O wired functions. The respective programming configuration is strictly dependent on system and sprinkler installation.
Indicators: Long-life indicator lights to show, power supply status, pump running, motor status, pressure switch on, automatic mode excluded, manual reset, alarm stop.
Buttons: Push button to manage manual start or manual stop, alarm reset and menu selection.
Fuse protection: Protection fuses, capable of carrying the start current for a period of no less than 20s.
Motor startup: Contactor for direct-on-line starting up to 55kW.
Motor protection: Only for signaling.
Priming tank monitoring: By float switch to keep the water level at minimum 2/3 of the priming tank.
Power monitoring: Current, voltage, phases, cos phi and power of the pump.
Monitoring and controlling: Pump room temperature, working hours of the motor, pump status, pump statistics and starts, maintenance program.
Fault message and acknowledgment: All alarm messages are displayed via LEDs or the graphic LCD. The LEDs color and alarm code must be acknowledged.

Conforms to the following standards:
- Fixed automatic sprinkler systems (EN 12845), part for pumps with electric motor
- Electrical equipment of machines (EN 60204-1)
- Low-voltage switchgear and control gear assemblies (EN 61439-1 and EN 61439-2)
- Electromagnetic compatibility (EMC) — Immunity for industrial environments (EN 61000-6-2)
- Electromagnetic compatibility (EMC) — Emission standard for residential, commercial and light-industrial environments (EN 61000-6-3)
Wilo E control devices can be used to control pumps with an electric motor, sensors for pump management and the level of information. The microprocessor-controlled switchgear is used to control and regulate all required functions of a pressure-boosting system according to EN 12845, for test purposes or actual sprinkler events.
The operating logic for the fire extinguishing system is based on the cascade calibration of the pressure switches 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. As a result, the main pump is started using switchgear. If the electric main pump does not start in systems with multiple pumps (for example due to problems with the power supply), a pressure drop will activate the pressure switch of the standby pump, which starts this pump. In some cases, two or more electric pumps can be used.
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. The stop buttons on the front door must then be pressed to stop the pump.
