Detector test
(OP)
I didn´t find it in the search window, so what percentage detectors in a new building do we have to test for the acceptance test acording to NFPA 72?

RE: Detector test
Plus good idea, because even with the modern tech and especially computer programming of panels, thanks sometimes just to not work.
And especially if you are talking about a high rise.
Not near the book till Thursday

From the first link above
Chapter 14 of the National Fire Alarm and Signaling Code includes requirements for testing of all fire alarm system components and subsystems. Initial acceptance testing of the entire system in accordance with the test methods prescribed in Chapter 14 is re- quired before the system can be approved and put into service.
RE: Detector test
(g) Smoke detectors
(1) In other than one- and two-family
dwellings, system detectors and single- or
multiple-station smoke alarms
Smoke detectors/smoke alarms shall be tested in place to ensure smoke
entry into the sensing chamber and an alarm response. Testing with smoke
or listed aerosol, acceptable to the manufacturer of the aerosol or the
manufacturer of the smoke detector/smoke alarm and identified in their
published instructions, shall be permitted as acceptable test methods.
Other methods listed in the manufacturer’s published instructions that
ensure smoke entry from the protected area, through the vents, into the
sensing chamber shall be permitted.
Any of the following tests shall be performed to ensure that each smoke
detector is within its listed and marked sensitivity range:
(1) Calibrated test method
(2) Manufacturer’s calibrated sensitivity test instrument
(3) Listed control equipment arranged for the purpose
(4) Smoke detector/control unit arrangement whereby the detector causes a
signal at the control unit when its sensitivity is outside its listed sensitivity
range
(5) Other calibrated sensitivity test method approved by the authority having
jurisdiction

-By the way, we are using intelligent Siemens smoke detectors.
-This paragraph says "each smoke detector" but the tests that follow seem that shall be done at the factory?
RE: Detector test
So to me the default would either test one for the entire system or all of them.
Plus in one year on the inspection you are supposed to test every device. So if you do it yearly, seems like you would check it on initial.
RE: Detector test
NFPA 72 2010
10.18.2.4.1 Verification shall ensure that the installed system includes all components and functions, that those components and functions are installed and operate as required, that the system has been 100 percent acceptance tested in accordance with Chapter 14, and that all required documentation has been provided to the system owner.
Exception: Where the installation is an extension, modification, or reconfiguration of an existing system, the verification shall be required for the new work only, and reacceptance testing in accordance with Chapter 14 shall be acceptable.

Thank you
RE: Detector test
They are not that intelligent.
Just even on simple systems, have seen them not work or do wacky things!!!
