ABSTRACT:
A system or method for interconnecting a security system with a telephone system. The system comprises one or more lockout modules that are connected between non-priority telephone devices and a telephone line. A security panel is directly connected to the telephone line. The lockout modules comprise a switch means for disconnecting the telephone device attached thereto from the telephone line when the security panel connects to the telephone line. The lockout modules further comprise a latch device that gives the first non-priority telephone device to connect to the line exclusive use of the line against other non-priority telephone devices. The lockout module further comprises a circuit that inhibits the reconnection of the telephone devices to the line to allow the security panel to recover a high and dry telephone line. The lockout module may be modified to include a switch that allows other non-priority telephone devices to share the line.
