![]() Where many speakers are deployed in a room / building, volume can self-adjust to the background noise levels at each speaker location. This unique Algo feature is called Ambient Noise Compensation. However, the 8180 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 8180 speaker. Support is available for RTP multicast, in addition to Polycom Group Page, Singlewire InformaCast (part no. 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. 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 SIP Audio Alerter 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 8180 SIP Audio Alerter supports multicast send or receive. Scale Algo IP Paging Speakers with Multicast For an isolated and balanced output to eliminate the possibility of hum / noise use the 8301 SIP Paging Adapter & Scheduler. Note: The 8180’s audio output is not isolated and balanced. Where audible and visual telephone ring alerting is required, the 8180 can be combined with an Algo strobe light using multicast or a relay.Īvailable outputs on the 8180 include: external speaker (8 ohm), audio output to bridge to an analog amplifier, and a relay input or output for interfacing an accessory (e.g. Note: The same performance is also achieved using the outdoor rated 8186 SIP Horn Speaker as an all-in-one PoE solution. If the optional 8 ohm analog weatherproof 1186 Horn Speaker is combined with the 8180 speaker then the volume is twenty times louder for loud ringing. The 8180 is typically eight times louder than a telephone speaker for loud ringing. 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. Several default ring tones are available in 8180, however, custom WAV files can be uploaded to the device. The WAV file will play for the duration of the ring event until the call is answered. Typically the speaker will be configured in a ring group to include a telephone(s). The 8180 will play a ring tone WAV file saved in 1GB device memory when this extension is called. The Ring extension on the 8180 is used for loud ringing / night bell applications. 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 8180 SIP Audio Alerter supports the Wideband G.722 HD voice codec.
