SP2 is one of GAI-TRONICS’ most advanced paging and intercom systems. Combining the simplicity of “press to page, release to party” operation with cutting-edge multicast Voice over Internet Protocol (VoIP) technology, SP2 is capable of providing virtually instant communication in the most demanding of environments. With the SP2 to Page/Party interface it is possible for existing users of Page/Party and ICS equipment to add SP2 stations to their systems.The SP2 to Page/Party interface includes six independent 33? to IP multicast conversion circuits, allowing a single unit to interface a page line and up to five party lines.
