Changes to California Shunt-Trip Rules

I've been informed by my good friend, Bill Mitchell, Schindler Elevator Corp., of a major change in the requirement for shunt-trip power disconnection in California.  The Office of the State Fire Marshal (SFM) has made changes to the 2010 edition of the California Building Code (CBC), based on the 2009 International Building Code (IBC).  The entire text of the changes is available online at: 
You might note that the title of this document reads:
FINAL EXPRESS TERMS FOR PROPOSED BUILDING STANDARDS OF THE OFFICE OF THE STATE FIRE MARSHAL REGARDING THE 2010 CALIFORNIA BUILDING CODE CALIFORNIA CODE OF REGULATIONS, TITLE 24, PART 2 2010 INTERIM RULEMAKING CYCLE
However, a representative of the SFM indicated that these changes to the regulations have formally been adopted by the California Building Standard Committee.  You may wish to verify this on your own but I am assured that this is now a part of the new California Fire Code. 
I’ve copied and pasted below the specific section of the referenced document:

CHAPTER 30 - ELEVATORS AND CONVEYING SYSTEMS
3006.4.1 Automatic sprinkler system. Automatic sprinklers shall not be required to be installed in the elevator hoistway, elevator machine room, elevator machinery space, elevator control space, or elevator control room where all the following are met:
1.  Approved smoke detectors shall be installed in the elevator hoistway, elevator machine room, elevator machinery spaces, elevator control spaces, or elevator control rooms and connected to the building fire alarm system in accordance with Section 907. 
2.  Activation of any smoke detector located in the elevator hoistway, elevator machine room, elevator machinery space, elevator control space, or elevator control room shall cause the actuation of the building fire alarm notification appliances in accordance with 907.
3.  Activation of any smoke detector located in the elevator hoistway, elevator machine room, elevator machinery space, elevator control space, or elevator control room shall cause all elevators having any equipment located in that elevator hoistway, elevator machine room, elevator machinery space, elevator control space, or elevator control room to recall nonstop to the appropriate designated floor in accordance with CCR Title 8, Division 1, Chapter 4, Subchapter 6, Elevator Safety Orders.
4. The elevator machine room, elevator machinery space, elevator control space, or elevator control room shall be enclosed with fire barriers constructed in accordance with Section 707 or horizontal assemblies constructed in accordance with Section 712, or both. The fire-resistance rating shall not be less than the required rating of the hoistway enclosure served by the machinery. Openings in the fire barriers shall be protected with assemblies having a fire protection rating not less than that required for the hoistway enclosure doors.  The exceptions to Section 3006.4 shall not apply.
5.  The building fire alarm system shall be monitored by an approved supervising station in accordance with 907.
6.  An approved sign shall be permanently displayed in the elevator machine room, elevator machinery space, elevator control space, or elevator control room in a conspicuous location with a minimum of 1½ inch letters on a contrasting background, stating: NO COMBUSTIBLE STORAGE PERMITTED IN THIS ROOM  By Order of the Fire Marshal [or name of fire authority]
This is great news as most in our industry have long argued against having machine rooms, control rooms and hoistways sprinkled and the power shunt-tripped.  I’m proceeding with the engineering of a number of elevator major alterations where we are verifying or correcting the fire-resistive nature of the elevator spaces and removing all of the sprinklers. 
As always, I must qualify that you should independently verify all code questions with the proper authorities having jurisdiction. 
Cheers,
Your Code Reporter

  2. Elevator Access Control System is an innovative design to restrict user access to different floor to enhance the security and accessbility of the user.The system allows a
    user to access the elevator with multiple floor selection which can be assigned throught the software.Once user prersents the card, the lift system will permit access to
    the floor by activating the relay to the corresponding floor.The system works with different technologies which allow flexibility of access solution.This solution
    will give a peace of mind to prevent unnecessary access and uninvited intruders.It also allows you to track the history by generating various type of reporting.
