This acoustic warning device is connected to a SHEVS Control Centre or Control via the option WTM.
The multiple tone sounder complies with the provisions of the EN 54-3 standard and VdS standards. It emits a two-tone alarm that is automatically synchronised. A total of 32 selectable tones are available.
Strobe light BL 4
This optical warning device is connected to a SHEVS Control Centre or Control via the option WTM.
The strobe light reports alarms via an optical signal that can be set either as a continuous red light or as a red single or double strobe with a frequency of 1 Hz.
Thanks to the power-saving LED technology, the batteries of the Control Centre or Control are conserved. This is particularly important when many strobe lights are to be connected.
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.
