A communication link between a monitored premises and the FMC SRC (Signals Receiving Centre) can consist of either an “Active” or “Passive” connection and/or some combination of both methods. An Active connection means that the communication link is monitored on a continual basis, 24 hours a day, 7 days a week, 365 days a year. If communication between the monitored premises and the FMC SRC is interrupted for any reason, the FMC SRC is notified within seconds of the interruption and the FMC operator can take immediate action. A Passive connection consists of a communication link that is not monitored on a continual basis. When a fire alarm monitoring panel using a passive connection has data to send, it will establish a link with the SRC, transmit it’s data and then disconnect. Passive connections are programmed to send a test signal into the SRC only once every 24 hours, and in the event an interruption in communication occurs, it can take 24 hours or longer for the SRC to be notified. When monitoring over a “Passive” connection, CAN/ULC-S561 requires that 2 non-redundant forms of communication are used. Current methods of communication for this method include Analog Phone (POTS) lines, Cellular, and Internet (IP).
