SELECTOR VALVES
Standard EN12094-5 requires that selector valves be opened within a maximum time span of
3 seconds, the following rules will be used for designing all selector valve systems:
•
Always confirm the duration for which the solenoid valve will be kept energized by the con-
trol panel. The solenoid must be energized for the full discharge time.
•
Removal of an electric actuator from the solenoid on the back-plate manifold shall result in
an audible and visual indication of system impairment at the extinguishing control panel.
•
A handle shall always be provided with selector valves for manual opening or closing.
