Hello, our company is simply renovating now, and the property management company forced us to install fire horns? Is it reasonable and legal?

If your company installed a fire broadcast during the main construction, you need to adjust the broadcast to a suitable position during the secondary renovation to ensure that all rooms in your company can hear the sound of the broadcast. If a part can't hear the broadcast because of the wall partition, it is necessary to increase the fire broadcast in that part.

If there is no fire broadcast in your company during the main construction, it shall be borne by the property.
