The 8180 SIP Audio Alerter is a SIP compliant PoE network audio device for loud ring and voice paging applications using dual endpoints. When registered with a SIP server, one endpoint will play an audio file from internal memory upon ring detection. The second endpoint will auto-answer for voice paging, complete with two-way talkback.

Equipped with a high efficiency integrated amplifier and tuned high quality loud speaker, the 8180 is typically eight times louder than a telephone speaker. If the optional 1185 Horn Speaker is used, then the 8180 can be twenty times louder. Several audio files are pre-loaded into the 8180 internal memory for ring sounds but users may also record or upload custom audio files, music, sound effects, or voice announcements.

The advanced features of the 8180 include SoundSure™ technology which automatically adjusts loud ring and paging volume to compensate for background ambient noise. Ideal for variable noise environments (restaurants, workshops, classrooms, etc.), SoundSure™ ensures that ringing or paging is always heard but not unnecessarily loud.

Outputs for external speaker, slave amplifier, or visual alerter plus multicasting capability enable many more options to enhance notification and alert capabilities. Configuration is possible using the feature buttons or web interface.

How much coverage does one 8180 SIP Audio Alerter provide?

There is no simple answer to this question but here are a few fast guidelines for maximum listener distance for different ambient noise levels:

Loud Ringing Voice Paging
Environment SPL (dBA) Effect 8180 Alone 8180 + 1185 Horn Speaker 8180 Alone 8180 + 1185 Horn Speaker
Home or Quiet Warehouse 50-55 Sounds are easily heard >250m (820 Feet) Horn not required 64m (210 Feet) >250m (820 Feet)
Normal Conversation, Office 60-65 Voices easily understood 128m (420 Feet) >250m (820 Feet) 32m (105 Feet) 64m (210 Feet)
Factory, Busy Restaurant, Vacuum Cleaner 70-75 Voices raised 32m (105 Feet) 128m (420 Feet) 8m (26 Feet) 32m (105 Feet)
Machine Shop, Screaming Child 80-90 Conversation is difficult, hearing protection possibly worn 8m (26 Feet) 32m (105 Feet) 2m (6.5 Feet) 4m (13 Feet)

For 8180 at maximum volume and ambient noise measured at listener location. Voice paging distance limits assume average speech level 12dB below peak.
