ABSTRACT:
An alarm for multistaged heat detection is provided. The alarm provides a multi-point detecting structure by applying a digital operation unit. The alarm has both pre-alarm and normal alarm modes. The digital operation unit coordinates the sound and light output to effect different alarm signals. A power capacity checking circuit is included to indicate a low operational state of the system power. A coercing alarm circuit is also included for stopping all detecting to cause the system to output an alarm signal in an emergency.
