The Pfannenberg PRO L 10 Ex is a combined audible and visual signalling device for hazardous areas: gas zone 2 (3G) and dust zone 22 (3D), as well as North American Class I/II/III Div 2. The cast aluminium housing is very robust, and the seal and screws are captive, which shortens installation. The sounder reaches up to 116 dB(A) at 1 m. There are 80 selectable tones plus 3 externally selectable tones, and the sound level can be reduced by up to 30 dB, also separately for pre-alarm and main alarm. The LED light can be continuous, blinking or flashing. The device runs on 10–60 V DC (rated 12–48 V DC) and has inrush current limitation. The lens is red.
