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 elevator 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.
For incoming calls, the LSD-2 can route calls to the DEVICE 2 (PRIORITY) port using Caller ID, Distinctive Ring, or Quick Call Back. All other calls will be routed to the DEVICE 1. Alternatively, the LSD- 2 can be set up so that all inbound calls are routed to the DEVICE 2 (PRIORITY) port.
Note: Caller ID is not passed through the LSD-2 to the devices.
Important: When the emergency device is in use, the phone line is not available for normal use. Any additional emergency calls will have to be made on another phone line. For this reason the LSD-2 is not recommended for single line applications.
