WSO-N signalling device

Non-intrinsically Safe Optical and Acoustic Warning Signaling Device WSO-N
Application
Signaling Devices WSO-N are used to emit strong optical and acoustic signals at places with very high noise level. They cooperate with, among others, the industrial telephone sets TP-*. The control system of the separated electronic contact NO, NZ or feeding the control voltage.The signaling devices WSO-N have been designed to operate in non-methane zones of mining plants and in the manufacturing rooms of chemical plants, warehouses, fuel pumping stations and other industrial facilities where there is high noise level.

Cooperation
With the devices having separated control output NO, NZ or from the device providing the control voltage 12 - 14 V AC or DC.
