Fire Alarm Goes Off at School AGAIN

On 12 September 2022 at around 7:47 AM (two minutes into first period), the fire alarm went off. Just like last time, it was manually activated out of concern of a possible fire due to an air handler unit emitting smoke. My first period class is in the portables which have different alarms from the main building. All of the portables in the school district have Fire-Lite BG-12 pull stations (conventional, hex lock models) and either a System Sensor SpectrAlert Advance P2R horn strobe or a System Sensor L-Series P2RL horn strobe (for ones constructed after 2017) set on code 3 low volume. Almost all of the 15 portables have SpectrAlert Advance horn strobes but the portable that my class was in is one of two portables in my school that have an L-Series horn strobe. All the horns and strobes are completely out of sync but not really that loud.
