Ample provisions shall be made for the immediate notification or warning of all occupants and for the immediate transmission of an alarm to the fire department upon the discovery of a fire in such buildings as may be designated by suitable regulations issued by the state fire marshal, which may include buildings used for sleeping purposes, or in which persons congregate in such numbers or under such conditions as may create a serious congestion or panic hazard. The regulations shall provide for installation, arrangement, electrical and mechanical details, operation, maintenance and tests of all such alarm systems and other necessary details of such systems, including training of owners, tenants or their employees in methods of fire exit drills to ensure the efficient and safe use of the exit facilities in buildings, and to prevent panic, and in the coordination of such drills with fire alarm systems; provided, that where deemed necessary, such regulations may include the patrolling of a building by able-bodied watchpersons between the hours of eight o'clock p.m. (8:00 p.m.) and six o'clock a.m. (6:00 a.m.), which patrol work shall be supervised by an approved central station signaling system, or be checked through the use of an approved clock system. Where the clock system is used, the person in charge of the building shall review the records each morning and file such records consecutively for periods of one (1) year for the inspection of the state fire marshal or other officials.
