Viking Electronics VK-LSD-2 Viking Line Seizure Device

A Smart Line Sharing Device with Inbound Switching Capability! Why pay for a dedicated line for your elevator/emergency phone or alarm panel? The LSD-2 Line Sharing Device allows the user to share an existing phone line with an emergency phone or other priority alarm device. This can save hundreds of dollars a year over leasing a dedicated phone line. The LSD-2 can be used on any C.O. line or analog PABX/KSU station. An outbound call on the DEVICE 2 (PRIORITY) port takes priority over a call in progress on the DEVICE 1 port. Any call in progress on the DEVICE 1 port will be disconnected for 2 seconds, returning dial tone to the DEVICE 2 (PRIORITY) port. A busy signal is then sent to the DEVICE 1 port.
