Wireless Smoke Detector with 433MHz Transmission and 80dB Alarm

This wireless smoke detector is designed to provide early warning of smoke in indoor spaces, using a DC9V stacked battery (6F22/9V) for power. It transmits a wireless signal at 433MHz, 1 527, or 330K, with a transmitting distance of at least 100 metres in open space. The alarm sound exceeds 80dB, and the device includes a low voltage alert that sends a wireless low voltage code every 24 hours while the battery remains undervoltage. The detector operates between 0°C and +50°C and can handle relative humidity up to 95%RH without condensation. Its white casing and straightforward battery power make it a practical choice for homes, offices, and similar indoor environments.

Features and Construction

The detector combines a compact white housing with wireless transmission and a loud alarm. The source text specifies a quiet current below 10uA and an alarm current below 100mA, along with a 433MHz/1 527/330K wireless frequency. These details help you understand its power use and signal compatibility.

Material and Build

The housing is white, and the unit is powered by a DC9V stacked battery (6F22/9V). The source text does not list the exact plastic type or impact rating, so the build quality is described only by the given electrical and environmental specifications. The alarm current is under 100mA, and the quiet current is under 10uA, giving a clear picture of its typical power draw.

Size and Practical Fit

No physical dimensions are provided in the source text. The detector is intended for indoor use within the stated temperature and humidity limits. Its wireless design means it does not require hardwiring, but the transmitting distance of at least 100 metres in open space should be considered when planning placement relative to a compatible receiver.

Uses and Placement

This smoke detector is suitable for indoor areas where early smoke detection is useful. The wireless signal can reach a compatible alarm panel or receiver, and the low voltage reporting helps with battery maintenance. Placement should avoid conditions outside the 0°C to +50°C range or above 95%RH without condensation.

Event or Professional Use

For small offices, workshops, or temporary setups, the wireless transmission and battery power allow flexible positioning without wired infrastructure. The >80dB alarm provides an audible warning, and the 433MHz signal can be integrated with compatible systems. Always follow local fire safety regulations regarding detector placement and maintenance.

Everyday Home Use

In a home, this detector can be placed in hallways, living areas, or similar indoor spaces. The white casing blends with most interiors, and the 9V battery is easy to replace. The low voltage code transmitted every 24 hours under continuous undervoltage gives a regular reminder to change the battery when needed.

Benefits and Buying Value

The main practical benefits are wireless installation, a loud alarm, and clear battery status reporting. The detector uses standard 9V battery power, and its specifications are fully stated in the source text, allowing you to match it to your existing wireless system.

Reuse and Low Maintenance

With a replaceable 9V battery, the detector can be maintained without specialist tools. The low voltage code is transmitted every 24 hours while the battery is undervoltage, which helps you plan battery replacement. No further maintenance instructions are provided in the source text, so routine testing and battery changes are the primary care steps.

Why Choose This Product

Choose this detector if you need a wireless, battery-powered smoke alarm with a 433MHz/1 527/330K signal and an alarm output above 80dB. The source text confirms a transmitting distance of at least 100 metres in open space, operation from 0°C to +50°C, and humidity tolerance up to 95%RH without condensation. It is a straightforward option for indoor smoke detection without wired connections.
