Ohio Rev. Code § 3731.041
At a minimum, a fire alarm and detection system required by this section, as described in the state fire code adopted pursuant to section 3737.82 of the Revised Code, shall include the annunciation of any activated initiating device at a constantly attended location from which the structure's fire alarm system is capable of being manually activated. All other fire alarm and detection system components shall be installed in accordance with the building and fire code provisions in existence and applicable to such installations at the time the owner receives approval for the plans submitted pursuant to this division.
The owner of the transient hotel shall submit plans or drawings, specifications, and data prepared for the installation of that system to the building code official having jurisdiction over the transient hotel and the state fire marshal for approval. If the owner of the transient hotel is required to install a system or, if the owner of a transient hotel had installed a system that was approved by the building official having jurisdiction prior to the effective date of this section and is required to alter that system to comply with this division, the owner shall submit those plans or drawings, specifications, and data prior to installing or altering the system. No owner of a transient hotel who is required to install or alter a fire alarm and detection system shall install or alter that system until the plans are approved pursuant to this division. If the owner of the transient hotel wishes to allow guest stays for a continuous period of two hundred seventy days or less and the owner previously has installed a fire alarm and detection system in that transient hotel that satisfies the requirements of this section, the owner shall submit those plans prior to allowing guests to stay in the rooms designated under division (A)(3) of this section. Such an owner shall not permit guests to stay in transient sleeping rooms for a continuous period of two hundred seventy days or less until the plans or drawings, specifications, and data are approved pursuant to this division.
The state fire marshal shall conduct a review of the plans for all of the fire alarm and detection systems installed in accordance with this section concurrently with the review conducted by the building code official having jurisdiction and shall conduct that review in accordance with the provisions for such plan reviews as described in the state fire code adopted in accordance with section 3737.82 of the Revised Code. The state fire marshal shall approve or disapprove any plans submitted under this division within thirty days after the date the plans are submitted.
If the state fire marshal determines that such plans and systems meet the requirements of this chapter and the fire code adopted in accordance with section 3737.82 of the Revised Code, the state fire marshal, or a designee of the state fire marshal, shall provide written approval of the submitted plans and, if the system is installed in accordance with the state nonresidential building code and the state fire code, shall sign the certificate of occupancy for the structure incorporating the fire alarm and detection system installed in accordance with this section. Such approvals shall be the exclusive method permitted by the state fire code or any other regulations or codes adopted pursuant to section 535.373 or 737.21 of the Revised Code for approval of the fire alarm and detection system required by this section.
