Question

Why must an alarm system include a time delay for signals that are otherwise technically correct?

Accepted Answer

An alarm system uses a time delay, which is a short pause before a siren sounds, to stop false alarms. Machines sometimes send signals that are technically correct but wrong in the real world. A signal is a piece of electronic data that tells the system something is happening. Without a pause, the system might react to things like a gust of wind blowing a door or a pet jumping on a couch. Think of it like a teacher who waits a second before scolding a student to make sure they really saw someone talking. This delay lets the system double-check if the movement is a real threat, like a thief, or just a temporary bump. By waiting, the system stays reliable and prevents people from getting annoyed by loud sirens that have no reason to go off.
