Purpose

Signaling stations of PSO (S, G, Z, K, P) types are intended for sound warning and alarm signaling while their arrangement in stationary units and on vehicles, where availability of explosive mixtures is excluded under operating conditions. Stations PSO-P-RN are intended for operation in underground modes of mines and pits not being hazardous in relation of explosion of gas, steam or dust and have marking RN1 of mining standard equipment.

Features

The signaling stations have the possibility to receive sound signals differing with frequency and interruption. PSO-P has test button.

Design

Stations PSO-S, PSO-G, PSO-Z and PSO-K Stations PSO-S and PSO-G consist of the body and cover. Shock action electromagnetic mechanism, which effects membrane by striker and pin, is installed on the cover. Stations PSO-Z and PSO-K consist of body and cover. Shock action electromagnetic mechanism, which effects ring or bell hood by bracket of striker and pin, is installed on the body. Stations have gland for laying flexible or armored cable with diameter up to 12 mm. Terminal clamps and grounding clamps allow connecting of two wires with cross section up to 2.5 mm2 each and designed for current up to 6A. Station PSO-P Signaling station of PSO-P type consists of the body and cover, which are fixed with screws. On the station cover there is resonator, which is used for generation of sound signals. On the station body 4 glands are fixed for connection of two cables with diameter from 7 to 14 mm and two cable with diameter from 11 to 18 mm. Inside the body there is a block of electronic conversions, which is used to issue sound signals in the specified mode. For connection of external cables from sensors clamps are used. For mounting ease on the cover and body there are mounting braces in the form of sheds.
