Fire Alarm Systems |
 | | A fire alarm is a bell, klaxon, chime, horn, speaker, strobe, or other device which warns people in a building of a possible fire. |
 | | Fire alarms may be triggered automatically by smoke detectors, heat sensors or manually. |
 | | Fire alarm systems consist of a central control panel to which smoke detectors are connected, along with bells or horns that are activated when the system triggers an alarm. |
