Optical and acoustic alarmThe combination signal generator is a crucial component within a fully functioning alarm chain. When an alarm is triggered, it generates a loud interval tone with over 100 dB sound pressure. In addition to the acoustic protection, an optical alarm is given by a colored flashing light (flashing frequency: 2 Hz). The siren and flashing light can be controlled separately, so that both alarm signals can also be triggered separately.Easy installation indoors and outdoorsThe combination signal generator can be installed inside and outside the building - the robust plastic housing (IP34) offers protection against splash water. To guarantee a long service life, the combination signal generator should only be installed in a covered outdoor area. The power supply is external with 12V. Depending on the intended use, you can choose between the three different light colors red (SG1681), yellow (SG1682) and blue (SG1683).
