The new PB-3 Panic Button from Viking Electronics is designed to mount under a desk or countertop and place discreet emergency phone calls when activated. A built-in auto dialer will roll through up to five phone numbers and two central station numbers until the call is answered. After answering, a prerecorded location announcement is delivered to the called party and one-way audio is sent from the PB-3 for silent monitoring. The called party can engage in two-way communication after the call is connected by pressing touch tone “#.”
The PB-3 is phone line powered, touch-tone programmed and connects to an analog station port, PABX extension, CO line or FXS port on a VoIP ATA.
Details on the PB-3 are here.
Viking Electronics also has an IP version of the panic button, the PB-3-IP, which was introduced last month.
