Universal sound generator (PSG) with very high volume, many distinct signal tones, and outstanding installation flexibility for indoor and outdoor use (e.g. schools, airports, industrial sites, public buildings, and more). You can mount the PSG as you like: either directly on the wall or with the included accessories on the table or ceiling. You can also choose different beam angles. When it comes to power supply, you no longer have to think about which device variant you need. The PGS 230 can do it all: power supply 12/24 V AC/DC or 230 V AC

Thanks to the electromechanical sound generation through the membrane horns are ideal for signaling dangers in industrial plants, alarms, or as part of a fire protection system. Grothe trumpets reach a volume of up to 105 dB(A), focusing the sound through the funnel. The so-called combined trumpet offers acoustic and even greater security through the combination of optical signals.
