Description
Wideband IP Horn Speaker for Clear Paging and Emergency Alerts
The Algo 8186 SIP Horn Speaker, delivers crystal-clear wideband audio using the G.722 HD voice codec. It ensures exceptional clarity for IP paging, voice announcements, and emergency notifications. With superior STI-PA scores, it meets strict standards like NFPA 72 and NEMA SB-40, essential for Emergency Communication in Education.
IP Loud Ringer for Industrial and Outdoor Use
The 8186 includes a Ring extension for loud ringing and night bell applications. When called, it plays a stored WAV ringtone from its 1GB memory. You can join it in a ring group with other telephones for synchronized alerts.

Up to 10 ring extensions can be registered, allowing one horn to act as a loud ringer for multiple telephones. The 8186 is about 20 times louder than a standard phone speaker. For audible and visual alerts, pair it with an Algo strobe light via multicast or relay.
Scalable IP Paging with Multicast
The 8186 supports multicast send and receive, enabling seamless coverage for any building, campus, or enterprise. One registered speaker can multicast to countless Algo devices including IP speakers, strobe lights, paging adapters, and multicast-supported phones.

Multicast ensures cost-effective scalability, reducing SIP registrations since only the sending device must be registered. The 8186 also supports RTP multicast, Polycom Group Page, Singlewire InformaCast (8186-IC), and Syn-Apps Revolution.
Zone Paging Made Simple
The speaker allows up to 50 multicast paging zones. Zones can be mapped to SIP extensions or selected via DTMF keypress from any phone. For even more flexibility, additional Algo IP speakers can be configured for specific room paging, loud ringing, or emergency alerts.
Dynamic Volume Control and Talkback
With Ambient Noise Compensation, the 8186 automatically adjusts its volume to match background noise. This ensures clear and comfortable sound levels in every environment. The built-in microphone also supports two-way Talkback, enabling real-time communication during paging.

Multi-Application SIP Extensions
The speaker supports multiple SIP registrations:
Page Extensions (50) – for auto-answer PA announcements.
Ring Extensions (10) – for custom ringtone playback.
Emergency Alert Extensions (10) – for safety, security, and event notifications.
Each extension can play custom WAV files stored in the device memory, making the 8186 a flexible tool for voice paging, alerts, and notifications.
Reliable Emergency Notification Alerting
The 8186 offers two activation options for emergency events:
Dial an Emergency Alert extension.
Trigger via a connected button or relay input.

Up to 10 emergency alerts can be configured (e.g., lockdown, evacuation, all clear). Alerts play until canceled or for a pre-set duration. Custom WAV files can be stored in memory. You can also integrate Algo 1202 or 1203 buttons for contact-closure activation, with three response modes — play/multicast an alert, call and play WAV, or initiate a two-way call.
Common Deployments
When paired with the Algo 8301 SIP Paging Adapter & Scheduler, the 8186 enables multi-zone PA systems with scheduled bells and announcements, synchronized with IP clocks. The 8301 can bridge analog systems and multicast audio to Algo IP speakers, simplifying hybrid setups.
Ideal for Industrial and Educational Applications
In addition, the 8186 works seamlessly with the Algo 8301 SIP Paging Adapter & Scheduler to build a comprehensive public address (PA) system. With this setup, users can manage scheduled bells, announcements, and synchronized IP clocks. Furthermore, the 8301 can simultaneously output audio to legacy analog paging systems and multicast to Algo IP endpoints.
