Alarm Operation

First Alert alarms emit a 2‑second chirp on power‑on, then a continuous 3‑second alarm if smoke is detected. The test button triggers a short chirp to confirm sensor function. The unit silences when the button is pressed again. Alarm stops after 30 seconds of silence!

Smoke Detection and Notification

First Alert smoke detectors employ a photoelectric sensor that continuously monitors the air for particulate matter. When a threshold of smoke density is reached, the unit triggers a 2‑second chirp followed by a 3‑second alarm that repeats until the source is extinguished or the alarm is silenced. The alarm sound is designed to be loud enough to wake most occupants, but the manufacturer notes that the device is not intended to alert hearing‑impaired residents, special purpose alarms should be installed for that demographic. The detector also features an escape light that illuminates the exit path during an alarm, aiding evacuation. In the SMCO100 model, the smoke alarm is paired with a carbon‑monoxide sensor, but the CO alarm is not yet available for hearing‑impaired users. The unit is UL217 certified, ensuring compliance with safety standards. Users are advised not to install detector guards unless the combination has been evaluated and found suitable, as guards can impede smoke detection. The alarm is powered by a sealed 10‑year battery, eliminating the need for frequent battery checks. When smoke is detected, the alarm chirps for 30 seconds to indicate detection, then continues until the user presses the test button to silence it. The system also provides a low‑battery indicator that chirps once every 30 minutes, prompting replacement. The notification system is designed to alert occupants quickly while maintaining reliability over a decade of use!!
