The Intrunet outdoor siren communicates wirelessly thanks to an extension of the SiWay protocol named Si2Way. This communication protocol allows Si2Way components not only to send information to the control panel‚ but also to receive commands from the panel. The ISRW6-12R comes with an embedded Si2Way radio module and powerful standard batteries ensuring a long maintenance cycle. The activation of the siren can be either time-limited or disabled if required by the application. In addition to the powerful acoustic signal (100 dB at 1 m)‚ an integrated light strobe flashes up siren activation.
