First Alert FG250BA Battery Smoke Alarm with Tamper Resistant Features

The First Alert FG250BA Battery Smoke Alarm uses a dual ionization smoke sensing chamber that is effective at detecting small particles from flaming fires. The unit features an 85dB horn for alerts, a supervised 9V battery power supply, and a full-function test switch to ensure proper operation. It includes a silence feature for unwanted alarms and a red LED light to indicate power status or alarm activation. A tamper-resistant locking pin secures the alarm cover to prevent battery removal. The compact and low-profile design fits seamlessly into any setting, and installation can be done while mounted on the ceiling or wall, thanks to its hinged cover. When the voltage drops to a pre-set level, the unit will chirp once a minute to indicate that a battery replacement is needed. The design also prevents the cover from closing without a battery installed, ensuring proper usage. This smoke alarm is designed for wall or ceiling mounting and includes necessary mounting anchors and screws. It is approved for use in recreational vehicles.
