how does a repeater system enhance fire service communications quizlet

Buildings, tunnels, topography. Graad 11 Wiskunde Vraestel 2 November 2017, Simply put, a radio repeater takes a poor, weak or ineffective radio signal and amplifies it as well as rebroadcasts it. Study FF Ch. Walter Leal Hamburg, This is used to extend the range of coverage of a radio signal. The phase in a 911 call during which the telecommunicator asks questions to obtain vital information such as the location of the emergency. So telephone repeaters have to be bilateral, amplifying the signal in both directions without causing feedback, which complicates their design considerably. One radio communicates up to the repeater, this is called uplink, and then the repeater repeats that transmission down to the radio on the other side of the hill, this is called downlink.

Most of the work this week focused on updating the extracted portions of the Code, with a few technical issues carrying over from the first, Second Draft meeting back in September. The term "repeater" originated with telegraphy in the 19th century, and referred to an electromechanical device (a relay) used to regenerate telegraph signals.[1][2]. For the 2012 edition of this Code, the mandatory reference to NFPA 72 was added to Section 11.10 for enforcement where the AHJ determines that a building requires such a system to facilitate fire department communications in the building. Determining exactly which units to send to a call depends on the location of the incident and. An optical communications repeater usually consists of a phototransistor which converts the light pulses to an electrical signal, an amplifier to increase the power of the signal, an electronic filter which reshapes the pulses, and a laser which converts the electrical signal to light again and sends it out the other fiber.

How have you addressed the provisions in NFPA 1 that rely heavily on AHJ decision and approval with regard to two-way communication systems? In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Notifies operator to ask caller for more information. The 2009 edition of NFPA 1 provided guidance on the design of two-way radio communication enhancement systems in Annex O. Annex O was deleted for the 2012 edition, because much of its criteria was incorporated into NFPA 72, National Fire Alarm and Signaling Code at the time. In computer networking, because repeaters work with the actual physical signal, and do not attempt to interpret the data being transmitted, they operate on the physical layer, the first layer of the OSI model; a multiport Ethernet repeater is usually called a hub.
