Operation
The LSR-1 Line Seizure Relay allows a standard phone line, analog PABX station, or
Centrex loop start line to be shared with an emergency phone, alarm system or any other
telecom device that needs instant access to a phone line. When the emergency device
comes off hook, the line is disconnected for two seconds to access fresh dial tone, then
reconnected to the emergency device.
The LSR-1 connects the incoming phone line to the device connected to the STD PHONE
port. The EMERG PHONE port is supplied with internally generated 32V DC talk battery.
When an "off hook" condition is sensed at the EMERG PHONE port, an internal relay breaks
the connection to the STD PHONE and holds both devices off the line simulating a two
second hang up. Another relay then connects the EMERG PHONE to the incoming line.
The emergency device receives fresh dial tone and is now able to dial out.
All incoming calls are routed to the STD PHONE port unless power is removed from the
LSR-1. To program or call into a device connected to the EMERG PHONE port, disconnect
the power to the LSR-1 and call into the unit.
