The smoke alarm went off at night because it detected smoke or fire in the vicinity, which triggered the alarm to alert people of potential danger.
The smoke/fire alarm will go off or you will see smoke. You could also see the fire.
There are several possible reasons why a fire alarm might go off in the middle of the night, including smoke or dust triggering the sensor, a malfunction in the alarm system, or a low battery. It's important to investigate the cause to ensure your safety.
Smoke alarms are hung so that if there is a fire you will know it. If toast is smoking then the alarm will detect it.
An automatic alarm system detects fires and sets off the alarm even if there is nobody around to detect the fire. A manual system will only go off when someone pulls the alarm switch after smelling or seeing smoke or seeing or feeling heat of a fire.

If you set the alarm (i.e. lock the car) and then disconnect the battery, the alarm will go off. If you disconnect the battery when the alarm is not set (i.e. when the car is unlocked) the alarm will not go off. (So don't try to nick a locked one).
A hardwired fire alarm may go off randomly due to issues like dust accumulation, electrical problems, or a malfunctioning sensor. It is important to regularly clean and maintain the alarm to prevent false alarms. If the issue persists, it may be necessary to contact a professional for further inspection and repairs.
