Is sensitivity testing of each smoke detector required on an addressable system?
All smoke detectors, whether addressable or not, are required to be sensitivity tested. Under NFPA 72 Chapter 10 Table 10.4.2.2 item g, test methods that are allowed include a calibrated test method, manufacturer’s calibrated sensitivity test instrument, listed control equipment arranged for the purpose, smoke detector/control unit arranged for the purpose, or other calibrated sensitivity test method approved by the Authority Having Jurisdiction (AHJ). Many of the newer addressable fire systems have the control equipment listed to automatically confirm the sensitivity of the smoke detectors. It’s advisable to check with your equipment manufacturer.
