Different fire alarm systems may be connected in several ways.
Some school alarms are monitored at a local fire dispatch center, or have a direct connection ("master box") via the municipal fire alarm system, or both. Others are monitored by a private security company ("proprietary monitoring") that will call 911 when a fire signal is received. Other school fire alarms (especially in rural areas) may have auto-dialers that reach the local fire department paging system or someone else responsible for dispatching the local fire brigade.
In rare cases, the fire alarm is not connected to anything, so when the alarm goes off, someone must be nearby to hear it and report it to the fire authorities.
