Universal Security Instruments Smoke and Fire Alarm AMI3051SB

No, you do not. This unit features a sealed 10-year battery designed to last for the entire lifespan of the alarm, eliminating the need for annual battery changes.

This technology combines photoelectric and ionization sensors to detect both fast-flaming fires and slow-smoldering fires. By analyzing multiple fire profiles, it can better distinguish between a genuine emergency and common household nuisances like cooking smoke, which helps reduce false alarms.

No, this is a standalone unit. It is designed for individual operation and does not feature interconnectivity, meaning it will not trigger other alarms in your home if it detects smoke.

Installation is straightforward and designed for DIYers. Since it is battery-operated and requires no hardwiring, you can easily mount it on either a wall or ceiling using the included hardware.

The unit includes an end-of-service life warning. Once the 10-year lifespan is reached, the alarm will signal that it is time to replace the device to ensure your home remains protected.

This model includes a dedicated hush button. If the alarm is triggered by a non-emergency event like cooking, you can press the button to silence the alarm temporarily while you clear the air.
