Leased Lines
•The Auxiliary Fire Alarm System utilized leased lines from the local telephone company for signal transmission.
• A leased line is always active

McCulloh Loop
• The next major improvement to fire alarm signal transmission came in the early 1880’s with the development of the McCulloh Loop. The benchmark for reliability. The first transmission technology used by supervising station systems.
• This circuit allowed multiple manual call boxes to share a single circuit connected to the monitoring station.
• The Code Wheel method of signal transmission is still in use in some areas today.

NFPA adjusted the name of “Other Transmission Technologies”
NFPA72 – 1999 “Other Transmission Technologies”
NFPA72 – 2007 “Other Transmission Technologies”
NFPA72 – 2010 “Alternative Technologies”
NFPA72 – 2013 “Performance – Based Technologies”
The last sentence of A.26.6.2.2 contains important guidance: “It is further expected that suitable proposals for stating the requirements of such technology will be submitted for inclusion in subsequent editions of this code”.

NFPA makes it easier to use Alternative TechnologiesNFPA 72 – 2110 26.6.3.1.4.1 Single Communications Technology. Where only one communications technology is used, any failure of the communications path shall be annunciated at the supervising station within 5 minutes of the failure.
NFPA 72 – 2013 26.6.3.1.5 Single Communications Path. Unless prohibited by the enforcing authority, governing laws, codes, or standards, a single transmission path shall be permitted, and the path shall be supervised at an interval of not more than 60 minutes. A failure of the path shall be annunciated at the supervising station within not more than 60 minutes. The failure to complete a signal transmission shall be annunciated at the protected premises in accordance with Section 10.15.

NFPA makes it harder to use Phone Lines
NFPA72 – 2010 26.6.3.1.4.2 Multiple Communications Technologies. Where two or more different technologies are used, the following requirements shall be met:
(2)Failure of any communications path shall be annunciated at the supervising station and at the protected premises within not more than 24 hours of the failure.
NFPA72 – 2013 26.6.3.1.6 Multiple Communications Paths. If multiple transmission paths are used, the following requirements shall be met:
(1)Each path shall be supervised within not more than 6 hours.
(2)The failure of any path of a multipath system shall be annunciated at the supervising station within not more than 6 hours.

NFPA makes is harder to use Phones Lines
NFPA72 – 2013 26.6.3.2.1.4 Transmission Channels.
(A) A system employing a DACT shall employ one telephone line
(number). In addition, one of the following transmission means shall be employed:
(1) One-way private radio alarm system
(2) Two-way RF multiplex system
(3) Transmission means complying with 26.6.3.1
