- What is the difference between an approved
automatic sprinkler system and approved
supervised automatic sprinkler system - How does the sprinkler system affect my fire
alarm system design - How do I know that the sprinkler is required to
be supervised - Is it acceptable to chain open the main supply
valve as prescribed in NFPA 13 and meet the
intent of a supervised system - If my fire alarm system is connected to the
building sprinkler system is it then
automatically required to transmit off site to a

- 9.7.2.1 Supervisory Signals. Where supervised
automatic sprinkler systems are required by
another section of this Code supervisory
attachments shall be installed and monitored for
integrity in accordance with NFPA 72 National
Fire Alarm Code and a distinctive supervisory
signal shall be provided to indicate a condition
that would impair the satisfactory operation of
the sprinkler system. Monitoring shall include
but shall not be limited to monitoring of
control valves fire pump power supplies and
running conditions water tank levels and
temperatures tank pressure and air pressure on
dry-pipe valves. Supervisory signals shall sound
and shall be displayed either at a location
within the protected building that is constantly
attended by qualified personnel or at an
approved remotely located receiving facility.
(Note This offices interpretation of
constantly attended location is 24 hours a day
7 days a week and 365 days a year.)

supervision of automatic sprinkler systems is
provided in accordance with another provision of
this Code waterflow alarms shall be transmitted
to an approved proprietary alarm receiving
facility a remote station a central station or
the fire department. Such connection shall be in
accordance with 9.6.1.4. (Therefore based on this
requirement the proposed fire alarm system cannot

- Mandates for supervised automatic sprinkler
systems are rarely in the _.3.5 Extinguishing
Requirements in occupancy chapters in the Life
Safety Code. - These requirements are typically given as a code
trade-off to extend travel distances dead-end
corridors or common path of travel. - These requirements sometimes are stipulated in
minimum construction type limitations in specific
occupancy chapters.
7Does this mean that I am going to have to look
at other sections of the code other than fire
alarm section to verify that my fire alarm
design is code compliant

- Absolutely! The 2000 edition of the Life Safety
Code has changed a majority of the sprinkler
requirements and sprinkler exceptions to include
the term supervised. - You need to be code savvy.
- Understand other requirements that would mandate
a supervised automatic sprinkler system - this
will affect the design of your fire alarm system.

- What if the building is not required to have a
fire alarm system in accordance with the _.3.4
section of the occupancy chapter but the
building owner wishes to utilize a supervised
automatic sprinkler system to enhance an
architectural feature what would be the minimum
equipment to satisfy this requirement - The State Fire Marshals Office views these
supervised automatic sprinkler systems as
required fire alarm systems not providing
occupant notification at the protected premise.
Therefore the following equipment would be
required - Control Panel - Listed for the appropriate
signaling system type sprinkler supervision and
waterflow. - Manual pull station - See 1019.6.2.5 required
when the sprinkler system is down due to
maintenance. - Waterflow tamper devices
- Smoke detector - See 721-5.6 required if the
control panel is not located in a continuous
occupied area. - These systems can be submitted on the Fire Alarm
Exemption Request Form pursuant to State Fire
Marshal Memorandum 99-2.

- What is the difference between an approved
automatic sprinkler system and approved
supervised automatic sprinkler system - Supervised sprinkler systems are monitored for
integrity by the fire alarm control panel which
transmit signals (supervisory trouble and alarm)
to a monitoring facility. - How does the sprinkler system affect my fire
alarm system design - The supervisory requirements of NFPA 101 would
prohibit the fire alarm signaling system type to
be a protected premises or local. - How do I know that the sprinkler is required to
be supervised - Get a copy of the architectural review or ask
the design professional.

- Is it acceptable to chain open the main supply
valve as prescribed in NFPA 13 and meet the
intent of a supervised system - No! The requirements of 1019.7.2.1 stipulates
that the where a supervised automatic sprinkler
system is required by another section of the
code the supervisory attachments shall be
installed and monitored in accordance with NFPA
72. - If my fire alarm system is connected to the
building sprinkler system is it then
automatically required to transmit off site to a
monitoring facility - No! Only if other sections of the code require
the sprinkler system to be supervised.
