Three light emitters. Programmable model. Power supply voltage 6 / 12 / 24 V.


Provides light signal emission for personnel warning during emergencies.

Intended for use in indoor and outdoor explosion hazardous zones of hazardous objects, on transport vehicles and vessels. Can be applied in conditions of atmospheric precipitations and sun radiation exposure.


  • 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 with galvanic corrosion-resistant and protective varnish-and-paint coating. Cavity of housing is filled with epoxy compound. Three bright LEDs are placed on the front panel. The housing is equipped with cable fitting with unremovable cable. Is connected by four-wire scheme, given at picture.

Nominal power voltage, LEDs colours, glowing modes adjustment function and cable fittings sets are determined during order placement.

VS-4-P-3SF signal device is manufactured only in 12V or 24V modifications. The signal device has a possibility to chose one of four operation modes of each LED (glowing, flashing with frequency of 4,2 and 0,5 Hz). Adjustment is executed by magned applying to a certain point of the device.

Whe the power is on the LED starts glowing. VS-4-P-3SF is manufactured in priorly determined modifications. In 6V modification only the upper LED (emergency) will be glowing during power supply on both LEDs.
