IP Classroom Speaker – Clock for School PA Systems

The 8190 is a versatile PoE wide-band speaker-clock that is a compliant 3rd party SIP endpoint. The product is designed for public address (PA) voice paging and emergency alerting, and is compatible with most hosted / cloud and premise-based VoIP telephone systems. Although the 8190 is most suited for education, the speaker can also be deployed in any application environment requiring crisp clear audio with high visibility clock (e.g. manufacturing / plant / utility, government, healthcare, transport terminals, etc.). The 8190S model offers discrete LEDs including amber, blue, green and red (+ white using RGB) for visual alerting of safety, security and emergency events.

Instead of one speaker, the 8190 is built using a four-speaker line array which provides asymmetric sound dispersion for improved sound distribution in classrooms and other environments from a wall mounted position. Wideband G.722 HD codec support provides high intelligibility voice paging and notification alerting. This improves the speaker’s STI-PA intelligibility scores, which is important in meeting NFPA 72 requirements and the NEMA SB-40 standard for emergency communication in education.

Multiple SIP extensions can be configured for Page, Emergency Alert and Ring. On Page, the speaker will auto-answer for making PA announcements. On Ring and Emergency Alert extensions the speaker will play a configurable WAV file stored in the device memory, including ring tones for telephone alerting, notification alerts and informational announcements.

The 8190 supports multicast receive to permit deployment of many endpoints to cover a building, campus or enterprise. The 8190 can be combined with any number of other Algo IP speakers, paging adopters and strobe lights, in addition to multicast supported IP telephones. Compatible multicast formats supported include RTP, Polycom Group Page and InformaCast. Together with the Algo 8301 Paging Adapter & Scheduler, a school-wide PA system with multiple zones and bell scheduler can be easily configured.

Algo Classroom Speaker-Clock & Bell Scheduler

An integrated microphone will monitor and adapt the speaker’s volume to ambient noise levels. This means announcements and bell tones are always heard but never too loud. The microphone can also be enabled for hands-free talk back with the integrated back-lit call button.

The speaker includes an integrated digital clock which automatically synchronizes with network time. For maximum contrast, the digits are 2.3” tall and illuminated white on a black background and dimmable.

The 8190 is a self-amplified speaker. The endpoint is powered via PoE (IEEE 802.3af or the recommended PoE+ 802.3at). A wall mount bracket is included. The product is CSA/UL, FCC and CE certified.

  • IP speaker-clock for education and other suitable environments such as manufacturing/plant/utility, government, healthcare, transport terminals, etc.
  • Multicast PA announcements to many speaker endpoints for emergency and non-emergency applications. Using the 8190S model audible emergency notification alerts can be aligned with a visual alert color (e.g., Amber – Shelter, Blue – Medical, Green – Evacuate, Red – Lockdown, White – All Clear, etc.)
  • OSHA compliance
  • Scheduled or automated announcements. Using the Algo 8301 to multicast, announcements/tones can be played over any model of Algo IP speaker. For example, school (i.e., class changes, recess, playing an anthem, etc.), retail and healthcare announcements (i.e., store closing, visiting hours, etc.), and workplace shift changes, breaks, etc.
  • Combine with all variety of Algo visual and audible IP endpoints to create more comprehensive notification alerting solutions
