TMA Files Petition for Partial Reconsideration on New Part 90 Rules
Monday, March 11, 2019 | Comments

The Monitoring Association (TMA), formerly the Central Station Alarm Association, filed a petition for partial reconsideration of the FCC’s October 2018 report and order outlining new Part 90 rules.

The rules make central station alarm channels at 450 – 470 MHz available for other private LMR (PLMR) purposes. Licensees have an exclusive use opportunity for the spectrum with concurrence from TMA.

TMA requested that the FCC reconsider the portion of the order that modifies eligibility restrictions on the central station channels allocated for sending alarm signals as part of the low power pool group D frequencies. TMA demonstrated in the record that this small handful of channels are dedicated to sending safety of life and property messages in direct cooperation with public safety; that the group D frequencies are heavily used, and demand is increasing because of the retirement of the copper phone network and rapid changes in cellular formats; that the licensing of non-central station operations, especially those allowing voice communications, can disrupt the timely delivery of alarm signals reporting fires, home invasions, medical alerts and other emergency situations; and that there was no demand demonstrated in the record for noncentral station use of these channels. No party refuted these showings.

Moreover, the record included an industrywide consensus, adopted through the Land Mobile Communications Council (LMCC), making the higher powered voice channels available for noncentral station use while protecting the heavily used low-power channels for alarm operations.

“It is respectfully submitted that the order’s modifications of the use restriction on the group D channels creates the risk that frequencies needed for life safety alarm operations will be depleted in many markets by less urgent uses,” TMA said. “Such outcome runs counter to clear and unrefuted evidence in the record, reaches beyond the scope of the original rulemaking proposal without adequate justification, and ignores less restrictive alternatives established in the record. TMA appreciates the protections crafted by the order for central station frequencies in general but urges the commission to modify those protections to continue the eligibility restriction for the group D channels.”
