Light and sound annunciator TSZV-Exi/Exm-M/N-Prometheus

An explosion-proof light and sound annunciator (panel) is used as a light and sound warning device in fire alarm and fire extinguishing systems in explosive zones at closed facilities and open installations, and can also be used in underground mines, mines and their surface structures

• TSZV-Exm-M/N-Prometheus - for explosive zones of classes "1" and "2"
• TSZV-Exi-M/N-Prometheus - for explosive zones of classes "0", "1" and "2"

The siren can be used as information signs and displays.

Annunciator body material:

• TSZV-Exm-Prometheus and TSZV-Exi-Prometheus - made of high-strength ABS-plastic;
• TSZV-Exm-M-Prometheus and TSZV-Exi-M-Prometheus - from low-carbon steel sheet with a powder polymer coating;
• TSZV-Exm-N-Prometheus and TSZV-Exi-N-Prometheus are made of stainless steel.

The siren in a stainless steel housing is recommended for use in alkaline, acidic and other chemically aggressive environments. In conditions of exposure to sea water and salt fog.

The high degree of protection of the IP66 / IP68 shell ensures the use in conditions of strong dustiness, in damp and damp rooms, in open areas with wind and precipitation.

Annunciator power supply:

• DC voltage from 12 to 36 V;
• AC voltage from 12 to 28 V;
• AC voltage from 220 V.

Connecting the siren:

• 2-wire - turns on when power is applied;
• 4-wire - when the power is permanently connected, the siren switches to the "Alarm" mode when a control signal is received.

The siren meets the requirements for explosion-proof equipment and corresponds to the explosion protection marking:

• TSZV-Exm-M/N-Prometheus – РВ Ex eb mb I Mb X / 1Ex eb mb IIC T6 Gb X  
• TSZV-Exi-M/N-Prometheus – PO Ex ia I Ma X / 0Ex ia IIC T6 Ga X / Ex ia IIIC T85°C Db Х

When installed in mines and mines, the power supply is not higher than 12V

Operating temperature from -70 to +85 ºС
