(For example, elevator recall smoke detectors and/or duct smoke detectors may be tied into a sprinkler monitoring system control panel for supervision purposes, if a fire alarm system is not existing in the building. A separate dedicated control panel for each function is not required). A sign indicating all control panel functions shall be provided adjacent the control panel (For example:  “Sprinkler monitoring and elevator recall and supervisory control panel”).

ELEVATOR INTERFACE WITH FA SYSTEM WHEN A NEW FIRE ALARM SYSTEM IS INSTALLED
 

A.  EXISTING BUILDINGS

1. A fire alarm system upgrade, does not generate an existing elevator controller upgrade. If an elevator is upgraded or altered (elevator controller replacement, etc.) the requirements of ASME  A17.1 -2004, NFPA 72, 2010 ed, and items 2-4 below shall apply.

ITEMS 2 through 4 pertain to elevator controller replacements

2. High-rise buildings.  If the existing elevator was provided with a shunt-trip function, the fire alarm system shall maintain this function, unless the SFFD procedure for sprinklers removal was performed under separate permit. (Removal of sprinklers from elevator machine rooms/hoistways is only permitted in high-rise buildings).  See attached procedure for sprinkler removal approval in Addendum D below (Unless sprinklers are required by NFPA 13, 2010 edition, Section 8.15.5.6).

3. High-rise buildings.  If the existing elevator was not provided with the shunt-trip function, and existing sprinklers are located in the elevator machine room/ shaft, these sprinklers shall be removed, or shunt-trip function shall be provided.

4. Low-rise buildings.  If the existing elevator was not provided with the shunt trip function, and existing sprinklers are located in the elevator machine room/shaft, these sprinklers shall not be removed, and the shunt-trip function shall be provided. 

5. Low-rise buildings.  If new sprinklers are installed in an elevator machine room/shaft, the shunt trip function shall be provided.
 

B.  NEW BUILDINGS

1. High-rise buildings.  Sprinklers shall not be installed in the elevator machine room/shaft and shunt trip shall not be required (Except if required by NFPA 13, 2010, Section 8.15.5.6.

2. Low-rise buildings.  Sprinklers shall be installed in elevator machine rooms/shafts (unless an exception allows it to be omitted) and the shunt trip function shall be provided.  
 

SPECIFIC REQUIREMENTS FOR RESIDENTIAL OCCUPANCIES

1. Indicate on the plans the specific residential occupancy for the building (R-1, R-2, SRO, etc.)

2. If the building is classified as R-1, the FA plans shall show the required hearing-impaired devices and sequence of operation in specific units based on the numbers of units indicated in CBC Table 907.5.2.3.3

3. If the building is classified as R-2, incorporate CBC Section 907.5.2.3.4 as verbatim note onto the plans. (It is not required to provide all dwelling units with hearing-impaired devices in R-2 buildings)

4. For all R occupancies, Incorporate CBC Section 907.5.2.1.2 as verbatim note onto the plans (75dBA sound pressure is required throughout the R occupancy)
