Q: What code states that quarterly communication between our fire panel and our local fire department must be completed?
A: What used to be called the off-site monitoring transmission equipment has been changed to be called the “Supervising Station Alarm Systems – Transmitters” as defined in NFPA 72-2010. But they also changed the frequency of the test from requiring it to be conducted quarterly to be required annually, as described in Table 14.4.5, section 22 of the 2010 edition of NFPA 72. It also refers to Table 220.127.116.11, section 18 for test methods. So, the answer you are seeking is Table 14.4.5 section 22 of NFPA 72-2010.
