  • HD Voice clarity with wideband G.722 codec support

SIP Ceiling Speaker for IP Paging

The Algo 8188 is a SIP compliant IP ceiling speaker designed for voice paging and background music in commercial environments. It connects directly to a SIP infrastructure without an FXS port or analogue telephone adapter. Power over Ethernet provides both data and power over a single cable for simplified installation. The unit mounts blind into a ceiling cavity for a clean appearance.

PoE Power and Network Limits

The speaker draws a maximum of 12.95 watts under IEEE 802.3af Class 0 with a nominal idle draw of 2.5 watts. It requires a 48 volt PoE source compliant with that standard. Network configuration is handled through a web interface after the device announces its static or DHCP address. Multicast support allows scalable one-to-many audio distribution across the LAN.

Wideband Audio and Relay Integration

A 6.5 inch coaxial driver with a PEI dome tweeter and mica filled polypropylene cone delivers wideband G.722 HD Voice alongside G.711 and OGG Vorbis codecs. Dual SIP extensions separate paging from notification calls. A programmable dry contact relay output and a supervised input for an illuminated wall button enable integration with door strikes or visual alerting systems.

Questions about this item

Should I pick the 8188 for a single zone or deploy multiple units for building-wide paging?

The 8188 supports multicast receive and broadcast, so one unit covers a single zone while multiple units can be grouped for scalable, cost-effective paging across a building.

What does the 6.5‑inch coaxial driver with PEI dome tweeter deliver in a real installation?

The 6.5‑inch mica-filled polypropylene cone and PEI dome tweeter reproduce wideband G.722 HD Voice and music with clear intelligibility for announcements and background audio.

How does PoE IEEE 802.3af Class 0 power the speaker and what is the practical draw?

The speaker draws up to 12.95 W at 48 V PoE and idles at 2.5 W, so a standard Class 0 switch port supplies all power and network connectivity without a separate supply.
