发明名称 SUSPEND CODE FOR ALARM SYSTEM
摘要 The system generates alarm suspension codes without direct interaction with the alarm panel. The alarm control panel generates its own suspension codes for checking for proper validation when a suspension code is entered. The alarm panel generates suspension codes sequentially and will recognize any of several suspension codes that are current. The entry of a later suspension code cancels all earlier suspension codes.
