Two light emitters. Single sound emitter. Programmable model. Power supply voltage 6 / 12 / 24 V.


Provides sound and light signals emission for personnel warning during emergency situations.

Used in explosion-hazardous zones at indoor and outdoor sites of hazardous industrial objects, transport vehicles or vessels. Might be used in atmosphere precipitation or sun radiation affecting conditions.


  • housing made of aluminum alloy or stainless steel
  • various types of mounting devices for protective cable sheath (metal hose conduit, armored cable, pipe)

Design, principle of operation

The housing is made in aluminium alloy and has a galvanic corrosion-resistant and protective varnish-and-paint coating. Cavity of housing is filled with epoxy compound. На Piezo sound emitter and two monochristal LEDs are place on the front panel.  The cable fitting with non removable four-wire cable is placed on the bottom part of the housing. Signal device is being connected by a four-wire scheme, given at picture.

Nominal power voltage, LED glowing colour, sound signal adjustment, cable fitting type are determined during order placement.

VS-3-P-2SF-GS Signal device might be manufactured for 12V and 24V power voltage and provide possibility to choose the alarming modes. Has six available sound signals, two volume levels and four operation modes for each light indicator (constant glowing, flashing with frequency of 4, 2 and 0,5 Hz). Adjustment is executed with the magnet applying the certain place of the housing.

When the power is on the LEDs start gloewing and the modulated sound signal is emitted. VS-3-P-2SF-GS light and sound alarm is manufactured in priorly chosen modification.
