Reusable smoke detectors for use in kitchens or offices to detect gas alarms (1 pack)

SMALL BUT ACCURATE: This smoke detector uses photoelectric technology to detect smoke. It is more sensitive to light smoke and slow-burning fires, alerting you faster. Protect your home 24/7.

EASY INSTALLATION: The fire alarm installs easily with its mounting bracket. No wiring is required; you can install it wherever you want.

Audible and LED Warning: When the fire alarm detects smoke or combustion particles in the air, it will sound its alarms, and the red LED will flash rapidly to remind you to check.

SIZE AND CAPACITY: 4 inches in diameter x 1.22 inches deep. A house fire breaks out every 83 seconds. The fire detector can quickly identify the fire and allow the family to escape quickly.
