"Approved" means that the equipment has been approved or listed for a specific use by an independent testing laboratory or organization of national reputation.

"Commercial grade smoke detection system" means a system of smoke detectors in which each detector is listed to Underwriters Laboratory Standard 268, Smoke Detectors for Fire Alarm Systems, or to another standard approved by the state fire marshal. Sensors in a commercial grade smoke detection system shall be located so as to provide coverage at least equivalent to that which would be provided by smoke detectors installed as required in subrule 210.3(11).

"Dual sensor smoke detector" means a smoke detector which contains both an ionization sensor and a photoelectric sensor and which is designed to detect and trigger an alarm in response to smoke detected through either sensing device, or a smoke detector which has at least two sensors and which is listed to Underwriters Laboratory Standard 217, Single and Multiple Station Smoke Alarms, or to another standard approved by the state fire marshal.

"Fire alarm system" means a system or a portion of a combination system consisting of components and circuits arranged to monitor and annunciate the status of fire alarm or supervisory signal-initiating devices and to initiate the appropriate response to those signals.

"Multiple-station smoke alarm" means two or more single-station smoke alarm devices that are capable of interconnection such that actuation of one causes the appropriate alarm signal to operate in all interconnected alarms. Interconnection may occur wirelessly for residential smoke alarms.

"Single-station smoke alarm" means an assembly incorporating the detector, the control equipment and the alarm-sounding device in one unit, operated from a power supply either in the unit or obtained at the point of installation or both.

"Smoke alarm" means a single- or multiple-station alarm responsive to smoke. See also "single-station smoke alarm" and "multiple-station smoke alarm." Residential smoke alarms are required to be listed under Underwriters Laboratory Standard (UL) 217.

"Smoke detector" means a device that senses visible or invisible particles of combustion. Smoke detectors are typically listed under UL 268.
