Algo 8188 loudspeaker 2-way White Wired 8 W

The 8188 IP Ceiling Speaker is a SIP speaker used in a drop ceiling for voice paging. emergency. and playing music. The speaker is a fully compliant 3rd party SIP endpoint. As a result. this IP ceiling speaker is compatible with most hosted / cloud and premise-based VoIP telephone systems.Wideband IP SpeakerThe 8188 SIP Ceiling Speaker supports the Wideband G.722 HD voice codec. 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. 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.Clear. Crisp. Rich Audio – for Voice and Background MusicThe 8188 is a music capable speaker supporting the Super-Wideband frequency response. Using the music input of the 8301 IP Paging Adapter. music can be streamed to the 8188 speaker as 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.Scale Algo IP Paging Speakers with MulticastThe 8188 SIP Ceiling Speaker supports multicast send or receive. 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 8188 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.Support is available for RTP multicast. in addition to Polycom Group Page. Singlewire InformaCast (part no. 8188-IC) and Syn-Apps Revolution.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.Using Multicast for Zone PagingMulticast zone paging for up to 50 zones can be configured from a single 8188 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 8188 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. Ambient Noise Compensation helps to ensure that announcements and alerts are heard but never too loud. Talkback is supported in the 8188. This feature can be enabled for a page call using the speaker’s microphone.Multi-Application SIP ExtensionsMultiple SIP registrations are available in this IP speaker. including Page (50). Emergency Alert (10) and Ring (10) extensions. On Page. the speaker will auto-answer when called for making public address (PA) voice announcements. 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).Emergency Notification AlertingFor notification alerting of safety. security and emergency events there are two activation options available:Dial an Emergency Alert extension.Connect a button to the speaker’s relay input.Up to 10 Emergency Alert extensions are available to register on the 8188 SIP speaker. allowing for different types of alerts to be activated when the extension is called (e.g.. lockdown. evacuation. shelter. all clear. etc.). Custom WAV files can be uploaded to 1GB device memory. A Call to Cancel feature is available to allow the emergency alert to play continuously for as long as desired until cancelled. Alternatively. the WAV file alert can be configured to play for a pre-set duration. T
