UL 1730

STANDARD FOR SAFETY FOR SMOKE DETECTOR MONITORS AND ACCESSORIES FOR INDIVIDUAL LIVING UNITS OF MULTIFAMILY RESIDENCES AND HOTEL/MOTEL ROOMS

Scope

These requirements cover electrically operated smoke detector monitors intended to be used in ordinary indoor locations in accordance with the National Electrical Code, NFPA 70; the Life Safety Code, NFPA 101; and th e Standard for Household Fire Warning Equipment, NFPA 74.

As covered by these requirements, a smoke detector monitor is a unit that provides for the connection an d supervision of initiating circuits which are, in turn, to be connected to smoke detectors. The smoke detectors may be single station or multiple stat ion and are installed within individual living units of multifamily residences or hotel or motel rooms. The monitor provides alarm or trouble indications at an attended central monitoring location as a supplement to the signa l indication provided at the location of the smoke detector. These units are not intended for use as fire protective signaling control units.

In addition to smoke detector monitoring, a monitor covered by these requirements may provide for manua l activation of alarm signals within the individual living units (whether integral with the smoke detectors or not) on either an individual or zone basis.

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.

These requirements do not cover automatic fire d etectors or alerting devices not provided as part of the monitor, nor do they cover units intended for connection to smoke detectors that:

a) Do not have integral sounding devices or

b) Are installed in common areas of multifamily dwellings.

A product that contains features, characteristics, components, materials, or systems new or different from those in use when the Standard was developed, and that involves a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally anticipated by the intent of this Standard.
