Purpose
Stations PASV1-P are intended for sound and light alarm and warning signaling while their arrangement in stationary units and on vehicles with 1ExsIICT6 explosion protection marking and designed for operation within explosion hazardous areas, external and internal units according to chapter 7.3 in “Regulations for Arrangement of Electrical Installations”, GOST R 51330.9 and other regulatory and technical documentation determining applicability of electrical equipment within explosion hazardous areas.
Features
- In the signaling station there is a possibility to receive light and sound signals of various frequency and intermittence.
- If necessary, sound signal cutoff can be ensured in 3 minutes after actuation.
Design
Piezo buzzer and LED with several crystals of different color are installed on the box cover. From inside of the cover piezo buzzer and LED are filled with compound. Inside the body there are also electronic conversion block and connecting clamps. Cable gland and grounding bolts are installed in the body.
