Weidmüller’s PROtop and PROmax power supplies and PRO DM diode modules have been approved according to DIN EN 54-4. This means that they may now be used as power supply units for building fire alarm systems – making them a key factor in fire protection.
The devices in the PROtop, PROmax and PRO DM series are suitable for a wide range of applications in a variety of industries, including machine construction, shipbuilding and building installation. Buildings in particular contain safety areas that must function in a reliable, fail-safe way at all times. Fire alarm systems are one of these areas. The new approval according to DIN EN 54-4 ensures that fire alarm systems are supplied with power even in the event of a power failure.
Devices in some series have also been approved according to IEC/EN as well as UL 61010-1 and 61010-2-201. They have also been approved in accordance with UL HazLoc Class 1, Division 2 for potentially explosive atmospheres. Moreover, thanks to receiving DNV approval, the devices can also be used in maritime applications.
