Safety Alarms and Warnings
Safety alarms and warnings send out an audible or visual signal to warn individuals about potentially unsafe situations that could jeopardize their health or safety. In an emergency, Audible alarms integrate with security or fire alarm systems to sound a warning or send a message. When carbon monoxide and smoke detectors detect high quantities of CO or smoke in the air, they sound an alarm. Weather radios, lightning detectors, and outdoor warning systems all send out alerts or provide information about the weather. Hazardous regions or circumstances are signaled by strobe and flashing lights. To display the state of equipment, tower lights have lights of various hues.
