    1. (A) A plant shall be permitted to consist of one or more buildings under the same ownership, and the circuit arrangement shall be such that an alarm signal cannot be received from more than one transmitter at a time within a plant.
    2. (B) If such noninterference is not provided, each building shall be a plant.
    3. 23.19.3.9 One sprinkler supervisory transmission channel circuit shall serve not more than 25 plants. A plant shall be permitted to consist of one or more buildings under the same ownership.
13. 23.19.3.10 Connections to a guard supervisory transmission channel or to a combination manual fire alarm and guard transmission channel shall be limited so that not more than 60 scheduled guard report signals are transmitted in any 1-hour period.

(sssss) Add Section 23.20 to read as follows:

1. 23.20 Directly Connected Noncoded Systems. ©2002 NFPA *

2. 23.20.1 Circuits. Circuits for transmission of alarm signals between the fire alarm control unit or the transmitter in the protected premises and the supervising station shall be arranged so as to comply with the following provisions:

   1. (1) These circuits shall be arranged so that the occurrence of a single break or single ground fault does not prevent the transmission of an alarm signal. Circuits complying with this paragraph shall be automatically self-adjusting in the event of either a single break or a single ground fault and shall be automatically self-restoring in the event that the break or fault is corrected.
   2. (2) These circuits shall be arranged so that they are isolated from ground (except for reference ground detection) and so that a single ground fault does not prevent the transmission of an alarm signal. Circuits complying with this paragraph shall be provided with a ground reference circuit so as to detect and indicate automatically the existence of a single ground fault.
   3. (3) A multiple ground-fault condition that would prevent alarm operation shall be indicated by an alarm or by a trouble signal.
   4. (4) Circuits for transmission of supervisory signals shall be separate from alarm circuits.
   5. (5) The occurrence of a single break or a single ground fault on any circuit shall not of itself cause a false signal that is able to be interpreted as an alarm of fire.

   6. (6) The requirements of this section shall not apply to the following circuits:

      1. (a) Circuits wholly within the supervising station.
      2. (b) Circuits wholly within the protected premises extending from one or more automatic fire detectors or other noncoded initiating devices other than waterflow devices to a transmitter or control unit.
      3. (c) Power supply leads wholly within the building or buildings protected.

3. 23.20.2 Loading Capacity of Circuits.

   1. (A) The number of initiating devices connected to any signaling circuit and the number of plants that shall be permitted to be served by a signal circuit shall be determined by the authority having jurisdiction and shall not exceed the limitations specified in this subsection.
   2. (B) A plant shall be permitted to consist of one or more buildings under the same ownership.
   3. (C) A single circuit shall not serve more than one plant.

(ttttt) Add Section 23.21 to read as follows:

1. 23.21 Private Microwave Radio Systems. ©2002 NFPA *
2. 23.21.1 If a private microwave radio is used as the transmission channel and communications channel, supervised transmitting and receiving equipment shall be provided at supervising, subsidiary, and repeater stations.

3. 23.21.2 If more than five protected buildings or premises or 50 initiating devices or initiating device circuits are being serviced by a private radio carrier, the supervising, subsidiary, and repeater station radio facilities shall meet all of the following criteria:

   1. (1) Dual supervised transmitters, arranged for automatic switching from one to the other in case of trouble, shall be installed.
   2. (2) If the transmitters are located where someone is always on duty, switchboard facilities shall be permitted to be manually operated, provided the switching is able to be carried out within 30 seconds.
   3. (3) If the transmitters are located where no one is continuously on duty, the circuit extending between the supervising station and the transmitters shall be a supervised circuit.
   4. (4) Transmitters shall be operated on a time ratio of 2:1 within each 24 hours.
   5. (5) Dual receivers shall be installed with a means for selecting a usable output from one of the two receivers.
   6. (6) The failure of one receiver shall in no way interfere with the operation of the other receiver, and failure of either receiver shall be annunciated.

4. 23.21.3 Means shall be provided at the supervising station for the supervision and control of supervising, subsidiary, and repeater station radio transmitting and receiving equipment. If the radio equipment is remote from the supervising station, this shall be accomplished via a supervised circuit.

   1. (A) The following conditions shall be supervised at the supervising station:

      1. (1) Transmitter in use (radiating).
      2. (2) Failure of ac power supplying the radio equipment.
      3. (3) Receiver malfunction.
      4. (4) Indication of automatic switchover.
   2. (B) It shall be possible to independently deactivate either transmitter from the supervising station.
