The corridor ticks every 10 second.

The corridor ticks every 10 second. It may be a smoke alarm or an emergency light. Suggest looking for property maintenance.

Usually, the fire-fighting facilities in the corridor will not be noisy. This phenomenon may be that there is something wrong with the equipment, so find a property management to solve it. The sound of patrol inspection of fire protection system indicates that the system is in normal working condition. If the smoke alarm goes off every few tens of seconds, it won't break down, but it is actually a reminder that there is no electricity. The property should replace the battery in time. Otherwise, disturbing the people is second. In case the electricity is really used up in the end, and in case of fire, it will be useless if you can't call the police in time.

If the emergency light rings every once in a while, it may be that the power supply of the emergency light is broken. You can check the wires, plugs or power supply. If it is the emergency light of the battery, it should be that the battery power is insufficient, and the normal power consumption should be 220V mains. Another possibility is that the emergency light is broken and can be repaired by professionals.
