8188 SIP Ceiling Speaker

PoE Wideband IP Ceiling Speaker for Voice Paging, Notification Alerting & Playing Background Music

The 8188 is a SIP compliant IP ceiling speaker for voice paging, emergency notification and playing background music. The speaker is PoE and does not require an additional amplifier. The 8188 is UL2043 certified for installation in air handling spaces. Common application environments include a school, hospital, retail store and office spaces. A Hydrophobic Membrane Screen can be attached to the speaker for placement in areas subject to moisture (e.g. shower). Algo 8188 IP Ceiling Speaker for Voice Paging, Notification Alerting and Playing Music

Wideband G.722 codec (HD voice) support in the speaker provides optimum speech clarity and intelligibility. Voice paging and emergency announcements can be easier to understand with wideband, particularly in a noisy environment. The super-wideband frequency response enables music quality far superior to narrowband IP or transformer coupled analog speakers. 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 8188 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.

The 8188 speaker registers as a 3rd party SIP endpoint with most hosted / cloud or premise VoIP telephone systems. For multiple speaker deployments, additional devices do not require a SIP license. A single registered speaker can be configured to multicast to any number and mix of additional Algo speakers, strobes and/or paging adapters as required, providing cost effective scalability using a minimum of network traffic. For multicast page applications, zoned paging is supported as a SIP extension or as a keypress selectable zone. RTP, Polycom Group Page, InformaCast and SA-Announce multicast types are supported.

Algo 8188 Multicast Paging

In a Polycom VVX environment the 8188 speaker may be configured to join a Polycom Group Page for coverage in common areas or for sound reinforcement. No SIP registration is necessary.

An integrated microphone in the speaker supports talkback. The microphone can also be enabled to listen for ambient noise, and automatically increase page volume when necessary1. This features ensures a consistent ratio of page to ambient noise level without being unnecessarily loud.

For ease and simplicity, the 8188 is PoE and can be installed as a blind-mount quickly into the ceiling. The speaker can announce its static or DHCP IP address, so access to an intuitive web interface makes configuring the device straight forward. Additionally, the 8188 speaker supports auto-provisioning for minimal touch configuration.

For indoor surface mount applications the 8188 speaker is available in an enclosure. Please refer to the 8189 SIP Surface Mount Speaker.

Emergency Notification Alerting

Algo 1202 Call ButtonAn auxiliary input allows an optional wall button (e.g., 1202 Call button as shown) or external switch to initiate a SIP call or play a WAV file stored in the speaker's memory for notification alerting.

A WAV file may also be played by dialing the speaker's Ring extension, configured for ring/announcement activation only. Up to 10 Ring extensions are available to register on a single speaker (or 8186, 8189, 8301) for applications requiring different types of emergency notification alerting (e.g., lockdown, evacuation, etc.). A Call To Cancel feature can be configured in the 8188 to allow emergency alerting to play continuously for the duration of the event, until a designated extension registered to the speaker is called to stop the alert. Any combination and number of Algo IP endpoints can receive a multicast for such emergency alerting.
