Product Overview
ALGO 8188 SIP Ceiling Speaker for voice paging, emergency notification, and background music.
Wide-band G.722 codec support provides optimum speech clarity and intelligibility in an HD Voice environment. Voice paging and emergency announcements can be easier to understand with wide-band, particularly in a noisy environment. The super-wide-band frequency response enables music quality far superior to narrow band IP or transformer coupled analog speakers.
Overview
The speaker may be configured as a third party SIP endpoint compatible with leading premise or hosted UC providers including Avaya, Broadsoft, Cisco, Digium Asterisk, Metaswitch, Mitel, and more. For multiple speaker deployments, additional speakers do not require a SIP license. Deployed as a SIP endpoint the 8188 can be configured to auto-multicast to any number of additional speakers as required, providing cost effective scalablity as well as minimizing network traffic.
In a VVX Polycom environment, hosted or in conjunction with Microsoft Lync, the speaker may be configured to join a Polycom Group Page for coverage in common areas or for sound reinforcement. No SIP registration is necessary. For all multicast page applications, zoned paging is supported.
Algo speakers are well suited for both general paging and emergency notification in retail, education, healthcare, and manufacturing. Wideband audio capability is helpful in meeting OSHA requirements as well as the NEMA SB-40 2010 standard for emergency communication in education. To support the reference to the intelligibility requirements of NFPA 72, the Algo 8188 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.
The integrated microphone enables talk-back and listens for ambient noise to automatically increase page volume when necessary1. This features enables a consistent ratio of page to ambient noise level without being unnecessarily loud.
An auxiliary input allows an optional wall button or external switch to initiate a SIP call or play a WAV file stored in speaker memory. The WAV file may also be played by dialing the speaker’s second SIP extension, configured for ring/announcement activation only.
For ease and simplicity, the PoE blind-mount speaker installs quickly into the ceiling, and announces its static or DHCP IP address for access to the intuitive web interface. Additionally, the 8188 speaker supports auto-provisioning for minimal touch configuration.
