MASTER SLAVE WIRELESS FIRE ALARM AND MASS NOTIFICATION SYSTEM

摘要

A wireless fire alarm notification system uses wireless repeater devices to annunciate an alarm to slave devices from the control panel. A notification device provides a local synchronization signal via wire to a secondary notification device. A method enables the activation or deactivation of child device without the child device having to query their parent repeater. A circuit to test the integrity of an active battery charger, a battery, and an isolation circuit is also shown. A method for qualifying that an RF signal meets a specified minimum acceptable level is described. A method for wirelessly sending events to avoid RF link overload is provided. A programming checksum method confirms that an annunciator has latest programming information. A method to automatically process messages from new devices without having to hardcode repeaters to support these new devices is also described.
