The AtlasIED IPX Series IP-SDH indoor wall mount IP speaker with Horn and display leverage the VoIP Communication solution to extend tele-presence with enhanced audio for those environments where network-wide communication is desired and that require large speakers with high output to overcome high ambient noise areas or large spaces. AtlasIED IP-SDH registers as a communication endpoint directly within InformaCast, and Revolution Advanced Notification applications, supporting both visual text and audio broadcast to enhance physical security while improving day-to-day communications through advanced alerting, bell schedules, pre-recorded, & scheduled announcements, while leveraging the WAN/LAN Network Architecture. When used within a Cisco Environment, these same IP speakers from AtlasIED can join Cisco's Unified Survivable Remote Site Telephony (SRST) as a supported device within SRST endpoint Architecture. Cisco's SRST provides remote location call-processing redundancy when access to the centralized Cisco Unified Communications Manager is interrupted because of a WAN outage. The ability of LAN communication between any combination of phones and speakers is particularly critical during an emergency (which may be the actual cause of the WAN outage). IP-SDH IP speakers with display provide equality "effective communication". "Under Title II of the ADA, all state and local governments are required to take steps to ensure that their communications with people with disabilities are as effective as communications with others." What does it mean for communication to be "effective"? Simply put, "effective communication" means that whatever is written or spoken must be as clear and understandable to people with disabilities as it is for people who do not have disabilities. Where 3rd party notification applications are not required, the IP-SDH speakers can register as SIP devices directly to a SIP server or VoIP Communications Manager for critical alerts /public address applications. Ideal for Corporate Applications, Education Institutions, Entertainment Complexes, Industrial Facilities, Government Buildings, Healthcare Facilities, Houses of Worship, Transportation Hubs - anywhere critical alerts / public address needs exist, and prefer using a single enterprise-class communications platform. Features IP-SDH indoor speakers are fitted with a highly efficient 15-Watt compression driver/speaker with a proven record of outstanding service reliability. A double re-entrant design provides superior sound level output and clear audibility of voice and tone alert notification and paging. The Grills for the IP-SDH IP speakers are made of 18-gauge metal construction that provides security and durability in commercial applications. The baffle is finished in neutral white electrostatic powder coat and is packaged with all necessary mounting screws.
