Description
The SPL-2010 optical-acoustic signaling device (siren) is designed for application in the burglary and assault signaling systems. The signaling function is performed in two ways: visually (by blinking of indicator LEDs situated in the lower part of the enclosure) and acoustically (by a modulated high-volume sound signal). As the light source, a set of LEDs is used, whereas the sound signal is generated by means of a piezoelectric transducer. Design of the signaling device housing as well as internal shield made of galvanized plate ensure a high degree of tamper protection (against opening, tearing off from the base, as well as against clogging of converter). The electronic circuit is made by the use of SMD technique and impregnated against the adverse influence of weather conditions, which ensures a high reliability of the device. As the SPL-2010 external housing is made of the PC LEXAN high-impact polycarbonate, it is characterized by a very high mechanical strength, and a nice appearance of the device is guaranteed even after many years of service.
