Algo 1186 Paging Horn


The Algo 1186 is a weatherproof horn for loud ringing and paging. This horn is compatible with Algo's 8180 SIP Audio Alerter and the 1825 Duet Plus Loud Ringer. The Algo 1186 significantly increases the ringing volume of a call alert and is approximately 20 times louder than the average SIP phone.

This is a great solution for loud, spacious and outdoor environments such as factories, warehouses and outdoor work yards. The Algo 1186 simply connects to the 8180 or 1825 and draws power from the host which means no additional power supply is required.
