Devicde can be installed in Zone 2 (II3G 3D) of gas hazardous area. See full description Functionalities: Certificates: Product description Technical details Warning LED Tower with Sounder LTT2 is a device dedicated to optical and acoustic signalling of the presence of hazards in the particular industrial installation. Device can be installed in Zone 2 (II3G 3D) of gas hazardous areas. Main features of the device: two light segments, available in 5 different colours. Segment could be 2-coloured, continuous / intermittent (blinking) signalling, flash light in red or yellow, acoustic signaller: one level of sound intensity (type PW-091-C), two level’s of sound intensity (type PW-091-S, PW-091-M), signalling up to two different alarm levels, with communicating the proper operational state (no failures) by the green colour, connections and control by on/off signals or by RS-485 (Modbus), installer friendly. Mistakes and errors in connections does not result in device damage, device can also easily communicate a proper operation of the connected (controlling) devices, including connection / control lines (type PW-091-S and PW-091-M).
