Horn engineered for industrial applications, ideal choice for short call or danger
signals.
Electronic version for continuous operation (SEM PLUS) also available.
This signal horn is also available with integreted luminous signaling: developed with
traditional Ba 15d lamp holder, steady light (SEM STEADY) and flashing light version
(SEM FLASHING), or with SMD LED technology (SEM LED).
This latter benefits from four luminous effects (steady light, single flash,
double flash, triple-flash) selectable via dip-switch.

For SEM STEADY and SEM LED it is possible to power sound and light separately.
