  • Method and apparatus for verifying operation of notification appliances during low input voltage condition
    Patent number: 7333010
    Abstract: A method for verifying operation of notification appliances on a notification appliance network during low input voltage conditions is provided. An output voltage is supplied to a network and is measured at a control panel. An input parameter is measured at a notification appliance connected to the network. A supply line impedance is calculated for the notification appliance based on at least one of the output voltage and the input parameter. At least one of the supply line impedance, the output voltage and the input parameter are used to determine a pass/fail condition for the notification appliance during a low voltage condition.
