The ISI (Interior System Interface) is a special adaptation of our Universal Remote Terminal Unit (U-RTU™). It is a wireless (VHF or UHF radios) or wired transceiver designed specifically to provide a simple way to interface the (Wide Area) Outdoor Emergency Warning System to interior systems. The primary purpose of the ISI is to provide a simple generic interface to almost any interior — paging system, emergency communication system, or voice type fire alarm system used for Mass Notification.
