Description

Protect your home with the FireAngel FA6615-R optical smoke alarm 2-pack. These smoke detectors are designed to provide a fast response to slow-burning fires that produce thick white smoke. By using an advanced optical sensor, these alarms are less likely to trigger nuisance alarms caused by everyday cooking fumes, making them a reliable choice for your household safety. Installation is straightforward and designed for convenience. The removable baseplate allows you to attach the unit to your ceiling, insert the batteries, and secure the alarm with a simple push and twist motion. If you are looking to upgrade or replace older units, the baseplate is compatible with FireAngel models ST-622, ST-620, and ST-750, ensuring a quick and easy setup process. This pack includes two alarms, providing essential fire safety coverage for multiple areas of your home.

Key Features

Fast response to slow-burning fires through an optical sensing chamber that detects thick white smoke quickly.

Reduced nuisance alarms thanks to an advanced optical sensor that helps prevent false alerts from cooking fumes.

Simple installation process involves attaching a removable baseplate, inserting batteries, and twisting the alarm to secure.

Easy replacement for existing FireAngel units as the baseplate is identical to ST-622, ST-620, and ST-750 models.

Reliable home safety with a 2-pack design to provide coverage in different areas of your residence.
