Wireless Smoke Detector with 433MHz Transmission and Low-Battery Alert for Home Fire Safety

This wireless smoke detector offers a practical solution for fire detection without the need for complex wiring. It uses a 433MHz wireless transmission to send alarms, with an open-distance range of at least 100 metres. The unit is powered by a standard DC9V stacked battery, making it easy to install and replace. An alarm sound above 80dB provides a clear warning, while the low-battery alert helps you keep the detector operational. The white housing suits most home interiors, and the device is designed for temperatures between 0°C and +50°C with up to 95% non-condensing humidity.

Features and Construction

The detector is built around reliable electronic components and a straightforward power design. Key specifications support efficient, long-lasting use in domestic environments.

Power and Efficiency

Operates on a DC9V stacked battery (6F22/9V), with a quiescent current of less than 10µA and alarm current under 100mA. This means the battery can last a long time under normal standby conditions, reducing maintenance frequency.

Wireless Transmission

Uses a 433MHz wireless frequency with an open-distance range of at least 100 metres. This allows the detector to communicate with other compatible receivers or central alarm panels, making it suitable for larger homes or interconnected setups.

Alarm and Alert System

Generates an alarm sound greater than 80dB to alert occupants of smoke. Additionally, the battery undervoltage alarm sends a wireless low-voltage code every 24 hours when power is low, so you know when to replace the battery.

Uses and Placement

This smoke detector is designed for indoor residential use, providing early warning of fire in key areas of the home.

Home Installation

Mount on ceilings or walls in hallways, living rooms, bedrooms, or near kitchens (avoid direct steam). The wireless design means no drilling for wiring, making it ideal for retrofits or rental properties.

Professional and Commercial Use

Suitable for small offices, workshops, or holiday lets where battery-powered wireless detection is preferred. The wide temperature and humidity range allow installation in many indoor environments without condensation issues.

Benefits and Buying Value

The detector offers practical advantages for ongoing fire safety management with minimal effort.

Low Maintenance Operation

The efficient circuit draws very little power in standby, and the low-battery alert prevents unexpected downtime. Simply test monthly and replace the battery when notified.

Cost-Effective Fire Safety

Battery power eliminates the need for an electrician to install hardwired alarms. The wireless feature allows you to link multiple units if desired, providing wider coverage without added complexity.
