Emergency Notification Alertingįor notification alerting of safety, security and emergency events there are two activation options available: For Ring and Emergency Alert extensions the speaker will play a configurable WAV file from 1GB device memory when the extension is called (e.g., ring tones for telephone alerting, notification alerts for safety / security / emergency events and informational announcements). On Page, the speaker will auto-answer when called for making public address (PA) voice announcements. Multiple SIP registrations are available in this IP speaker, including Page (50), Emergency Alert (10) and Ring (10) extensions. This feature can be enabled for a page call using the speaker’s microphone. Ambient Noise Compensation helps to ensure that announcements and alerts are heard but never too loud. Where many speakers are deployed in a room / hallway / common area, volume can self-adjust to the background noise levels at each speaker location. This unique Algo feature is called Ambient Noise Compensation. However, the 8188 speaker’s microphone can also be used to monitor and adapt speaker volume according to background noise levels. Speaker volume can be configured via the web GUI of the endpoint. Speakers with SIP registrations can also be configured to be a member / receiver of multicast zones. Note: Additional page zones can be configured by registering individual Algo IP speakers for specific room paging (e.g. Alternatively, in order to minimize SIP registrations, multicast page zones can be configured in the SIP Audio Alerter as a DTMF key press selection using the dial pad of telephone making the page call. Fifty (50) page extensions are available for this purpose. One option is to map multicast page zones to individual SIP extensions on the speaker. Multicast zone paging for up to 50 zones can be configured from a single 8188 IP speaker. Support is available for RTP multicast, in addition to Polycom Group Page, Singlewire InformaCast (part no. 8188-IC) and Syn-Apps Revolution.Īny combination and number of Algo IP endpoints can be configured as a multicast for emergency alerting to cover any size room, building, campus or enterprise. Devices configured to receive the multicast do not need registration.
Multicast provides cost-effective scalability using a minimum of SIP registered endpoints, as only the endpoint designated to send the multicast needs to be registered. There is no limit to the number of devices part of a multicast, and a minimum of network traffic activity is utilized.Ī single registered 8188 can be configured to multicast to any number and mix of Algo IP speakers, strobe lights, paging adapters and multicast supported IP telephones. As a result, many Algo IP speakers can be deployed to cover any size building, campus (e.g., classrooms in a school, college or university) or enterprise. The 8188 SIP Ceiling Speaker supports multicast send or receive. Scale Algo IP Paging Speakers with Multicast The music stream can be configured at a lower priority to allow voice paging, emergency alerts and scheduled tones / announcements to interrupt background music. Using the music input of the 8301 IP Paging Adapter, music can be streamed to the 8188 speaker as multicast. The 8188 is a music capable speaker supporting the Super-Wideband frequency response. For example, the 8188 IP speaker was measured to have a STI-PA intelligibility score of 0.95 in an office environment at 70 dBA level with ambient noise of 49 dBA.Ĭlear, Crisp, Rich Audio – for Voice and Background Music
The result is better STI-PA scores, which is important in meeting standards such as NFPA 72 and NEMA SB-40 for Emergency Communication in Education. Consequently, there is high intelligibility and clarity of audio from the speaker for IP paging of voice announcements and emergency notification. The 8188 SIP Ceiling Speaker supports the Wideband G.722 HD voice codec.
