Emergency Phone Panic Button Kit. The PB-1 Panic Button Kit connects to a Viking 1600A Series Emergency Phone to provide a one-way talk path to the pre-programmed number when used. The PB-1 will activate the 1600A Series Emergency Phone and light a red LED to let you know your call is connected. The receiving end will be able to hear everything happening at the installation site, but the site will not be able to hear anything from the receiving end, this makes it a very effective security measure, as there is no other indication that the site is being monitored.
