Product Overview

Ionization Sensor Detects Smoke from Flaming Fires

The First Alert SA303 Smoke Alarm features ionization smoke-sensing technology with an enhanced smoke-gathering design. Ionization sensors offer optimal smoke detection from flaming fires. The 85-decibel alarm is designed to be easily heard.

Easy-to-Use Design

This smoke detector utilizes a single button for simple operation. Press the button on the face of the fire alarm to silence false alarms from cooking smoke or shower steam, as well as to test the alarm to ensure it is working. A blinking power light informs you the smoke detector is operational, while a low battery-alert lets you know when it is time to change the battery.

Tamper-Resistant Battery Operation

A single 9-volt battery powers the First Alert SA303 Ionization Smoke Alarm, and there is a side-load battery drawer that slides open for easy battery replacement. The fire alarm features an optional pin to lock the battery and detector in place for tamper resistance, making it so neither the battery nor the smoke detector can be removed without the proper tools. This smoke detector can be easily installed on the wall or ceiling, and it is suitable for use in mobile homes and RVs.
