During a renovation or rehabilitation of a work area, is it really necessary to change all the iniatiting devices? I mean, after a renovation space we have to install new devices?
Building occupancy: Building offices with 6 level and 1 basement.
Who or where are you getting this requirement ??
Actually, it is a doubt because I know that the NFPA 13 indicates that it is not possible to reused sprinklers, so I was wondering if exist something similar in the NFPA 72/101 related to the initiating devices such as smoke/heat detectors or horn/strobes, etc.
I do not think so, as long as they meet the NFPA 25 testing criteria
What a great first name you have.
I would would say no its not necessary to change all initiating devices based on the meeting the requirement of Section 43.4 of NFPA 101.
In terms of 2009 edition of NFPA 101 for renovations, I consult Chapter 43 Building Rehabilitation. This will direct the user of the code to the requirements for life safety for the existing building during rehab projects. You need to read carefully to get an understanding of the Chapter. Since it is fairly comprehensive, I read it every time before I start to review a project.
During a rehabilitation project, a building must meet the base level of life safety required by the Code chapter applicable to the existing occupancy. For example, an high rise business occupancy undergoing rehabilitation must meet the requirements of Chapter 11 and 39 for existing business occupancies. See 188.8.131.52, 184.108.40.206(1).
This was really brief for the NFPA requirement. I always recommend discussing what the codes have to say with your AHJ.
Could it be that you're required to bring the the fire alarm system up to date and the new control panel will not accept the older initiating devices? I know of many projects where they needed to install new addressable panels but some devices were incompatible?
