AtlasIED IP-SDM-72 is an indoor wall mount IP endpoint speaker with integrated talkback microphone and LCD display. It compliments the Unified Communications (VoIP Communications) investment including on-premises and hosted infrastructure platforms so that information can be pushed to spaces beyond the world of desktop telephony communication and breaking any traditional audio-path barriers. AtlasIED IP-SDM-72 registers as a communication endpoint directly within InformaCast, GCK, and Syn-Apps' Revolution advanced notification applications, supporting 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 or LAN network architecture. When used within a Cisco environment, the IP-SDM-72 speakers can join Cisco’s Unified Survivable Remote Site Telephony (SRST) as a supported device. 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). Where 3rd party notification applications are not required, the IP-SDM-72 speakers can register as SIP devices directly to a SIP server or VoIP Communications Manager for critical alerts, intercom and public address applications. Under Title II of the ADA, all state and local governments are required to take steps and ensure effective communication to people with disabilities. The AtlasIED IP-SDM-72 IP speakers with talkback microphone and LCD display provide effective communication for all individuals. IP-SDM-72 includes an attached 25V/70V transformer on the rear of the speaker and a switch on the front baffle that allows selection between 25V/70V and network. This enables a facility to install the IP-SDM-72 and use an existing analog paging system to deliver messages until the controller and software are installed. Once that is complete, the grille can be removed and the switch changed to network causing the speaker to receive its information from the controller without the need to remove the speaker. This is ideal for retrofit applications or for systems where components are being installed in phases and the speakers must work during the rollout.
