We're assuming you set the alarm, and then it goes off for no reason. If your system uses magnetic switches on windows and doors, you may want to check the magnetic switches to make sure they are both properly closed, and functioning properly. As windows age, they may not close fully, and thus not always bring the two parts of the switch close enough together to register that the window (or door) is closed. You may also want to check that nothing is accidentally setting off any motion detectors you have. An overhead fan may cause a plant to move, or a cat may wander through -- any number of things can set off motion detectors.
When the smokes reaches the device and sets off the alarm
because it probably has a heat detector in the alarm therefor it goes off.
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.
Manually turning off a shunt trip breaker should not set off the fire alarm. The only way that the breaker could set off the fire alarm when turned to the off position is if there is an auxiliary contact on the breaker connected to the fire alarm circuit. This is not usually done because the breaker should be able to be turned off when doing maintenance on the breakers circuit. If the breaker is a mandatory feed breaker to a piece of fire alarm equipment and shouldn't be left in the off position it might have a trouble circuit connected to the fire alarm panel. A trouble alarm on a fire alarm panel is different from an alarm circuit alarm.
The smoke/fire alarm will go off or you will see smoke. You could also see the fire.
To effectively shut off a fire alarm, locate the alarm panel and enter the code or use a key to silence the alarm. If you cannot do this, contact the fire department for assistance.
To turn off a fire alarm in your house, locate the alarm and press the reset button or remove the batteries. Make sure to address any potential fire hazards before turning off the alarm.
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.
If there is a fire alarm going off you should call the fire department. There may be a gas or carbon monoxide leak. If the fire department is called, the landlord will be forced to do something.
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.
