ST-3s New

ST-3s are designed for visual and acoustic signalling of alarm conditions appearing on outputs of control modules.

The alarm devices have a splash-proof construction. They can be used inside buildings. They have an ordinary or explosion-proof construction, for use in zone 2 of gas explosion hazard or zone 22 of dust explosion hazard.

Features

• 3 LED lights in green, orange and red for continuous or flashing optical signaling;
• only 1 color on in a given state (when working with CB-ST interface): Normal condition = green, ALARM1 = orange, ALARM2 = red, ALARM3 = red+siren, Failure = flashing green (or no signaling);
• high intensity piezoceramic siren with continuous or intermittent operation;
• high durability and reliability, low current consumption;
• independent control of acoustic and visual signaling, continuous or intermittent – when working with CB-ST interface;
• splash-proof housing, for indoor use;
• simple installation (vertical only) on an angle bracket.
