SPW-100 is a siren with acoustic signaling, designed for indoor installation and provided with piezoelectric transducer. There are three types of modulated tones with 120 dB intensity to choose from. The loud signal ensures good audibility over a large area, e.g. in warehouses, production halls, parking lots inside buildings, etc. With its oval enclosure, TS-100 can be either wall- or ceiling-mounted. The device is provided with tamper protection against opening the enclosure or tearing off the wall/ceiling.
