SPW-250 R is a siren with acoustic signaling, designed for indoor installation and provided with piezoelectric transducer. It offers three types of 120 dB intensity modulated tones to choose from. The loud signal ensures good audibility over a large area, e.g. in warehouses, production halls, parking lots inside buildings, etc. Enclosure of the siren is made of polycarbonate, thus ensuring high mechanical strength and aesthetic appearance of the device that remains unchanged over time. The siren is provided with tamper protection against opening or tearing off the wall. Additionally, alarm will be triggered by loss of communication with the control panel or mains supply failure.

The SPW-250 optical-acoustic siren is available in three color versions: SPW-250 R (red), SPW-250 BL (blue) and SPW-250 O (orange).
