IP Paging

ALGO-8186 SIP Horn Speaker

The 8186 is a weatherproof SIP compliant IP horn speaker for voice paging, loud ringing, and emergency/safety/security notification.

The 8186 features dual SIP extensions for voice paging and notification capability. One or both extensions can be registered with any premise or hosted Communication Server supporting 3rd party SIP endpoints.

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 8186 can be configured to multicast to any number and mix of additional Algo speakers, strobes and/or paging adapters as required (e.g. 8128, 8180, 8186, 8188, 8301, 8373), 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 re-inforcement. 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 manufacturing/plant/warehouse, energy/utility, education, machine shop/garage and parking lot/yard. Wideband audio capability is helpful in meeting OSHA requirements as well as the NEMA SB-40 2010 standard for emergency communication in education.

The integrated microphone enables talkback and listens for ambient noise to automatically increase page volume when necessary. 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 for a notification alert. The WAV file may also be played by dialing the speaker’s second SIP extension, configured for ring/announcement activation only.

The 8186 SIP Horn Speaker is weatherproof and suitable for both indoor and outdoor locations when properly installed. Once deployed, the 8186 is easily managed using an intuitive web interface and supports autoprovisioning for minimal touch configuration.
