Additional RX1000A can be added to any TX/RX1000A up to 1,000 feet from the TX-1000A, or to wire additional notifiers (siren, strobe, speaker or buzzer).
An additional speaker can be wired to either the Av-200, RX1000A or RX2000A to provide notification in a separate room or location as an alternative to purchasing a second RX receiver.
