The passive radio astronomy service (RAS) is studying natural phenomena producing radio emissions at frequencies fixed by the laws of nature. Primary allocations have been made to various space services in the Earth-to-space direction such as the fixed-satellite service (FSS), radionavigation-satellite service (RNSS), mobile-satellite service (MSS) and broadcasting-satellite service (BSS) in bands adjacent or nearby to bands allocated to the RAS.

UL 38-2008火災(zāi)報警系統(tǒng)用手動信令盒

1.1 These requirements cover manual signaling boxes for fire alarm systems intended for permanentinstallation and used in ordinary locations in accordance with the National Electrical Code, NFPA 70, and the National Fire Alarm Code, NFPA 72.1.2 A manual signaling box is an assembly of a mechanism having electrical contacts designed totransmit a signal when an integral part is operated manually. The signaling contacts are intended to beconnected to circuits of fire alarm systems. The types of boxes covered by these requirements are coded boxes and non-coded boxes, including signaling boxes, fire and guard’s tour reporting stations, and guard’s tour reporting stations for suppressed-signal tour combinations.1.3 A manual signaling box having a pre-wound signaling mechanism and equipped with a trippingelectromagnet to permit automatic actuation by separate detectors, and similar combination devices, shall be evaluated with regard to compliance with the applicable requirements for both manual signaling boxes and electrically-actuated transmitters.1.4 A manual signaling box shall be constructed for use with system-control units, electrically-actuatedtransmitters, or similar units that will permit its application in compliance with applicable codes andstandards of the National Fire Protection Association.1.5 These requirements do not cover electrically-actuated transmitters.

UL 346-2005防火信號系統(tǒng)用水流量指示器

1.1 These requirements cover vane type waterflow indicators intended for use in fire protective signaling systems to be employed in ordinary indoor locations, in accordance with the National Fire Alarm Code, NFPA 72. 1.2 Waterflow indicators covered by these requirements include sizes 3/4 inch and larger. The indicator sizes refer to the nominal inside diameter of the main sprinkler pipe or tubing on which they are installed. 1.3 A vane type waterflow indicator is an assembly of a mechanism having electrical contacts arranged to transmit a coded or noncoded signal when the vane, located in the supply pipe (riser) of a sprinkler system, is moved by the flow of water in the pipe. This flow is normally caused by the opening of one or more sprinkler heads resulting from a fire condition. The signaling contacts are intended to be connected to circuits of private fire protective signaling systems. 1.4 These requirements do not cover pressure-operated waterflow indicators.

UL SUBJECT 2755-2011模塊化數(shù)據(jù)中心的研究概況

1.1 This Outline of Investigation covers Modular Data Centers (MDC). The Modular Data Centers coveredby these requirements are pre-fabricated units consisting of an outer enclosure housing ITE and varioussupport equipment such as electrical service and distribution equipment, HVAC systems and the like.Some configurations may have the support equipment housed in a separate enclosure. A typicalconstruction may use a standard ISO shipping container or other structure as the outer enclosure, racksor cabinets of ITE, NEC compliant service entrance equipment and power distribution components, powerstorage such as a UPS and an air or liquid cooling system.1.2 These factory-built modules incorporate pre-installed materials and equipment which, afterinstallation, may be concealed and may not be accessible for inspection at the final installation site.1.3 The modular data centers covered by these requirements are intended for fixed installation eitherindoors or outdoors based on their construction and resistance to environmental conditions. MDCsintended for outdoor use shall be identified with a NEMA environmental class rating.1.4 These requirements are intended to demonstrate compliance with the National Electrical Code (NEC),NFPA 70 and other national Codes such as Building, Fire, Plumbing, Mechanical, and the like. Wherestate or local codes differ from the national codes anticipated by these requirements, determiningcompliance with these codes is the responsibility of the local authority having jurisdiction.1.5 When these requirements do not cover a specific technology or construction feature, the applicablerequirements of the National Codes shall be used.1.6 This Outline of Investigation assumes that the final installation of the MDC will be performed byqualified service personnel in accordance with the applicable installation instructions, installation practicesand national installation codes. These MDCs are intended for installation subject to approval by theAuthority Having Jurisdiction.
