Fire alarm systems warn people when smoke / fire / carbon monoxide or other fire-related emergencies are detected in a home. These alarms can be activated automatically from smoke detectors and heat detectors, or through manual fire alarm activation devices such as manual call points or pool stations. These can also be speaker strobes that sound an alarm, then send a voice expulsion message to warn people inside the building not to use the elevator.
