Combined warning device MS-BL 4

This combined warning device combines the signal types of BL 4 and MS 4 in one device. Therefore, this compact device requires only half the space and installation effort. The combined warning device is connected to a SHEVS Control Centre or Control via the option WTM.

Like the MS 4, the MS-BL 4 is also certified according to EN 54-3 and by VdS. A two-tone alarm with automatic synchronisation can be composed from 32 selectable tones.

The red strobe signal has a frequency of 1 Hz. Thanks to the power-saving LED technology, the batteries of the Control Centre/Control are conserved.
