An integrated security control system and method which integrate the functions of a wireless security system control panel and a radio transceiver in an integrated security control system unit. The integrated control unit includes a first telephone communication system for communicating security system data by wired telephone communications, and a second radio frequency (RF) cellular communication system for communicating security system data by communications through an RF communication network. The cellular communication system is the primary communication network for reporting a security event, thereby leaving the first telephone communication system open for telephone communications during the reporting of a security event. A separate unit of the security system, such as a wireless RF status display or a wireless RF keypad, is provided with a beeper transducer for sounding entry and exit beeps. The separate unit is positioned at a separate location from the integrated security control system unit, such that the entry beeps do not alert an entering person to the location of the integrated security control system unit. When a security event is triggered, the control unit delays activating a security alarm sounder in the control unit until after the second RF communication system has finished transmitting the alarm message.

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.
