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. The speaker is a self-amplified PoE device. Wideband IP Speaker The 8189 SIP Surface Mount 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. Clear, Crisp, Rich Audio – for Voice and Background Music The 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. 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 Multicast The 8189 IP 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 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 Paging Multicast 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 & Talkback Speaker 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. Ambient Noise Compensation helps to ensure that announcements and alerts are heard but never too loud. Talkback is supported in the 8189. This feature can be enabled for a page call using the speaker’s microphone. Multi-Application SIP Extensions Multiple 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 Alerting For 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 8189 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 canceled. Alternatively, the WAV file alert can be configured to play for a pre-set duration. The user does not have to remain on the phone when calling the Emergency Alert extension. As soon as the call is made the Algo endpoint will play the WAV file as configured, making emergency alerting simple and efficient from any telephone or device in the UC environment. If the Call to Cancel extension is configured, the same canceling extension will apply to any of the Emergency Alert extensions registered. IP Loud Ringer The Ring extension on the 8189 is used for loud ringing / night bell applications. The 8189 will play a ring tone WAV file saved in 1GB of device memory when this extension is called. Typically the speaker will be configured in a ring group to include a telephone(s). The WAV file will play for the duration of the ring event until the call is answered. Several default ring tones are available in 8189, however, custom WAV files can be uploaded to the device. Up to 10 Ring extensions are available to register on a single speaker for this purpose, thereby allowing one speaker to act as a loud ringer for several telephones by configuring different ring groups for each registered Ring extension. Where audible and visual telephone ring alerting is required, the 8189 can be combined with an Algo strobe light using multicast or a relay.
