Fire pump control panel: This is one of the key components for ensuring that the pump starts up and operates in accordance with the provisions of UNI EN 12845 10.8.5. In this response, we outline the requirements mentioned and explain how to apply them in practice.

1) Where should the control panel be installed?
According to UNI EN 12845 10.8.5, the pump control panel must be located in the same compartment as the electric motor and the pump.
This point is not merely a “logistical” one: it serves to keep the control panel, motor, and pump as a coherent unit, reducing operational ambiguity and making it clearer where to take action if necessary. In practice, the position of the control panel is an integral part of the intended configuration.
2) Functions that the control panel must provide (UNI EN 12845 10.8.5)
Also in accordance with UNI EN 12845 10.8.5, the electric pump’s control panel must be capable of:
- automatically start the engine when it receives a signal from the pressure switches;
- Start the engine in manual mode;
- Stop the engine only by operating the control manually.
The key point is the balance between automatic operations (startup via pressure switches) and human control (manual shutdown): the configuration described emphasizes that startup must be able to occur automatically, while shutdown must not depend on automatic logic, except in the specific case mentioned below.
3) Engine Shutdown: General Rule and Specific Case—UNI 10779
The rule stated here is clear: manual stop only.
However, the text specifies an operational exception: if the pressure-boosting unit serves exclusively a hydrant network for activities that are not constantly monitored, the system may shut down automatically after the pressure has remained consistently above the pump’s start-up pressure for at least 20 consecutive minutes (see UNI 10779).
It is important to read the terms and conditions carefully here, because they are cumulative (exclusive hydrant service + unattended operation) and because the automatic activation is contingent on maintaining pressure above the threshold for the specified duration.
4) Where should the power supply for the control panel come from?
Regarding the power supply line, the text specifies that, where permitted by the electric utility, the power supply for the pump control panel must be taken upstream of the main circuit breaker for the buildings.
The phrase “where permitted” is crucial: it introduces an external constraint (the electricity grid operator) that must be verified. In practice, this means that the correct electrical solution is not determined “solely on paper,” but also depends on the conditions permitted by the delivery point and the grid operator’s rules.
5) Cable Protection: Fire and Mechanical Damage
One explicit requirement concerns cable installation and protection: all cables must be protected against:
- fire
- mechanical damage
Protection must be provided by walls, partitions, or floors with a fire resistance rating of at least 60 minutes.
This point directly links the “electrical” aspect to the “construction/partitioning” aspect: the required performance does not concern only the cable itself, but also the way in which the cable route is protected along the path and during installation.
6) Power supply dedicated exclusively to the pump unit
The text clarifies that the power supply for the pump control panel must be dedicated exclusively to the pump unit. The practical implication stated is that each electric pump unit will have its own dedicated power supply.
This requirement is intended to prevent cross-contamination: the line supplying the control panel (and thus the pump) must not be “shared” with other systems. From a management perspective, it also makes it easier to identify the line’s responsibilities and priorities, consistent with the role of the main fire-fighting electric pump.
7) Quick Checklist (Operational Summary)
If you need to do a quick check of the points mentioned, make sure that:
- The control panel must be located in the same compartment as the motor and pump (UNI EN 12845 10.8.5).
- The painting should:
- automatic startup via pressure switches;
- manual startup;
- Manual-only stop (except in the specific case described in UNI 10779).
- Automatic shutdown should be considered only in the specified cases (hydrant network, unattended operations, pressure above the threshold for 20 minutes).
- The power supply to the panel should be connected upstream of the building’s main circuit breaker, if permitted by the utility provider.
- Cables must be protected from fire and mechanical damage using components with a fire resistance rating of ≥ 60 min.
- The line should be dedicated exclusively to the pump unit (one line per unit).
Conclusion
The fire pump control panel must ensure essential functions (automatic start-up via pressure switches, manual start-up, and manual shutdown), be located in the same compartment as the motor and pump, and have a power supply line and cable routing designed for continuity and separation, including protection against fire and mechanical damage.
