The flashing light and siren can be mounted inside and outside your building. This combination signalling device is the crucial link of a fully functioning alarm chain. In the event of an alarm, the alarm sounder generates a loud intermittent tone with over 100 dB sound pressure. In addition to the acoustic protection, there is an optical alert from a colored flashing light (frequency: 2 Hz). The alarm sounder and the light can be controlled separately. The robust plastic housing (IP 34) of the combination detector offers protection against environmental influences. To ensure a long service life, you should install the signalling device under cover and protect it from rain. The flashing light and siren are supplied externally with 12V operating voltage. You can choose between three different light colors, according to taste: red (SG1681), yellow (SG1682), and blue (SG1683).
