SYSTEM FOR SENSING ALARMS EXTERNAL TO A WIRELESS SHORT RANGE RF NETWORK AND FOR TRANSMITTING SUCH ALARMS TO TRANSCEIVING DEVICES WITHIN THE RF NETWORK
摘要:
Short range RF networks for transmitting to a plurality of wireless RF transceiving devices within a defined area. The wireless devices within the defined area each include a short range RF device transceiver enabling the device to wirelessly communicate with a data processor controlled wireless transmission system within said defined area, including a centrally located short range RF system transceiver for transmitting accessed data to the wireless devices. The central system transceiver should have an RF transmission range covering the defined area. An RF channel(s) is set to be used only for alarms. Then if an external alarm is sensed, all transmissions along other channels in the transmission area may be overridden, and the alarm data broadcast over the dedicated channel to all operational wireless devices within the area.
