With the RXT-320 Transceiver, the Address Switch on the Wireless Interconnect PCA should be set to the
correct address for the alarm station. This switch is normally set at the factory. Each Wireless Alarm
Interconnect PCA must have a unique Modbus™ address to be recognized on the network. The alarm station
address must be in the range of 0x80-0x8F. The dial on the PCA sets the last digit (LSD) of the address, the
first digit of the address is fixed at ‘8’ hex. The Modbus™ address of the Interconnect PCA is utilized for
monitoring the Battery. For more information refer to the RXT-320 manual.
The A2V2 utilizes two batteries. Both batteries must be the same type. To install the battery packs, insure that
the area is de-classified. Remove the cover from the junction boxes. Remove the Battery Cap and install a
battery in each junction box. The batteries can only be installed one way, and orientation is mandated by the
battery supports and the connector. Insure that the batteries are completely seated and close the retaining lever
over the battery until it latches. The unit will power up and begin normal operation. Replace the cover on the
junction Boxes and insure that the covers are completely screwed down and secured by the cap-head screw.
