AtlasIED IP-HT47 70V Speaker Interface With Transformer

The AtlasIED IP-HT47 is a 70V speaker interface designed to work with AtlasIED IPX audio or visual endpoints in networked communication systems. In advanced notification environments using platforms such as InformaCast, GCK, and SA-Announce, it enables connection to 70V constant voltage loudspeakers to extend audio coverage beyond the endpoint itself. This makes it a practical choice for facilities that need broader audibility for scheduled messaging, bell signaling, prerecorded announcements, and emergency communications across LAN or WAN infrastructure.

In Cisco deployments, the IP-HT47 can be used alongside a compatible AtlasIED IPX endpoint to support 70V speaker operation within Unified Survivable Remote Site Telephony environments. That gives remote sites a path for local communication continuity if connectivity to a centralized Cisco Unified Communications Manager is disrupted. For organizations prioritizing resilient paging and emergency communication, that role is especially relevant.

The unit can also be used where third-party notification software is not required, allowing attached speakers to operate through an IPX endpoint registered directly as a SIP device to a SIP server or VoIP communications manager. Installation-oriented details include a low insertion loss transformer, WAGO 221 series wire nuts, and included mounting hardware.
