Abstract
Each of a plurality of satellite nodes coupled to a sensing device or an actuator and logically dispersed around an access node are configured to wirelessly communicate alarm conditions. A first satellite node detects and accesses an alarm condition and then prepares an alarm message containing an alarm code corresponding to the alarm condition and an address indication. The first satellite node may thereafter receive alarm messages from other satellite nodes logically further from the access node than the first satellite node. Alarm codes contained in the received alarm messages are filtered and compared to the alarm code of the prepared alarm message. The first satellite node includes a sender address in the prepared alarm message for each received alarm message containing an alarm code that matches the alarm code of the prepared alarm message. The first satellite node transmits the prepared alarm message to the access node.
