1.1 These requirements cover electrically operated smoke detector monitors intended to be used inordinary indoor locations in accordance with the National Electrical Code, NFPA 70; the Life Safety Code,NFPA 101; and Chapter 2 of the National Fire Alarm Code, NFPA 72.1.2 As covered by these requirements, a smoke detector monitor is a unit that provides for the connectionand supervision of initiating circuits which are, in turn, to be connected to smoke detectors. The smokedetectors may be single station or multiple station and are installed within individual living units ofmultifamily residences or hotel or motel rooms. The monitor provides alarm or trouble indications at anattended central monitoring location as a supplement to the signal indication provided at the location ofthe smoke detector. These units are not intended for use as fire protective signaling control units.1.3 In addition to smoke detector monitoring, a monitor covered by these requirements may provide formanual activation of alarm signals within the individual living units (whether integral with the smokedetectors or not) on either an individual or zone basis.1.4 An installation wiring diagram attached to the monitor, or referenced in the markings on the monitor,indicates the devices and circuits acceptable for connection to it in the field.1.5 These requirements do not cover automatic fire detectors or alerting devices not provided as part ofthe monitor, nor do they cover units intended for connection to smoke detectors that:a) Do not have integral sounding devices orb) Are installed in common areas of multifamily dwellings.1.6 A product that contains features, characteristics, components, materials, or systems new or differentfrom those covered by the requirements in this Standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements to determine that the level of safety as originally anticipated by the intent of this Standard ismaintained. A product whose features, characteristics, components, materials, or systems conflict withspecific requirements or provisions of this Standard shall not be judged to comply with this Standard.Where appropriate, revision of requirements shall be proposed and adopted in conformance with themethods employed for development, revision, and implementation of this Standard.
