The PoE 8189 SIP Surface Mount Speaker is identical to the 8188 SIP Ceiling Speaker. however. it is for indoor surface mount ceiling or wall applications required for voice paging. emergency alerting and playing music. The speaker is a fully compliant 3rd party SIP endpoint. As a result. this IP speaker is compatible with most hosted / cloud and premise-based VoIP telephone systems.The 8189 SIP Surface Mount Speaker is UL/CSA.
FCC and CE certified. Consequently. there is high intelligibility and clarity of audio from the speaker for IP paging of voice announcements and emergency notification. 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.Clear.
Crisp. Rich Audio – for Voice and Background MusicThe 8189 is a music capable speaker supporting the Super-Wideband frequency response. Using the music input of the 8301 paging adapter. music can be streamed to the 8189 speaker as multicast.
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. There is no limit to the number of devices part of a multicast. and a minimum of network traffic activity is utilized.A single registered 8189 can be configured to multicast to any number and mix of Algo IP speakers. strobe lights. paging adapters and multicast supported IP telephones.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.
Devices configured to receive the multicast do not need registration.Any 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.Support is available for RTP multicast. in addition to Polycom Group Page. Singlewire InformaCast (part no. 8189-IC) and Syn-Apps Revolution.Using Multicast for Zone PagingMulticast zone paging for up to 50 zones can be configured from a single 8189 IP speaker.
Zones can be selected one of two ways. One option is to map multicast page zones to individual SIP extensions on the speaker. Fifty (50) page extensions are available for this purpose.
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.Note: Additional page zones can be configured by registering individual Algo IP speakers for specific room paging (e.g. school classroom). Speakers with SIP registrations can also be configured to be a member / receiver of multicast zones.Dynamic Volume Control & TalkbackSpeaker volume can be configured via the web GUI of the endpoint.
However. the 8189 speaker’s microphone can also be used to monitor and adapt speaker volume according to background noise levels. This unique Algo feature is called Ambient Noise Compensation. Where many speakers are deployed in a room / hallway / common area. volume can self-adjust to the background noise levels at each speaker location.
