Keyword: Section15.231, Emergency Transmission

First Category: Radio Service Rules
Second Category: Part 15 General

Question:   Can a tamper alarm transmission exceed the 5 second limit of Section 15.231 (a) (1) & (2) under the certified conditions in Section 15.231 (a) (4)?

A tamper alarm transmission may exceed the 5 second limit only if the tamper alarm transmission occurs in very limited instances, such as when the likelihood of a security breach or emergency condition is very high.
 In this case, the Commission permits the duration of tamper transmissions to extend beyond 5 seconds as provided for by Section15.231(a) (4).
