Interlogix A2325SHR-M FM Audio Self Healing Ring-Master 1300NM

FM Audio Self Healing Ring-Master 1300NM, SM. The IFS A2300SHR series audio transceivers provide distribution of balanced line-level (2.2 V peak-to-peak) audio signals for emergency broadcast applications on two optical fibers. The modules allow for the configuration of a highly fault-tolerant emergency audio system. Utilizing a self-healing ring topology provides a redundant audio path via a counter rotating transmission on the second optical fiber which enables the system to provide circuit integrity in the event of a cable break. Both fault status indicating LED’s and hard-wired contact outputs are provided for each individual communication path for supervision of proper systems performance. Models within this series are available for use with multimode or single mode optical fiber. Plug- and-play design ensures ease of installation requiring no electrical or optical adjustments.
