Wireless Smoke Detector Fire Alarm with 433MHz, 80dB Alarm and 9V Battery

This wireless smoke detector is designed to provide an audible and wireless warning when smoke is detected. It runs on a DC9V 6F22/9V stacked battery and uses a 433MHz wireless transmission frequency along with 1 527 and 330K options. The alarm sound is rated above 80dB, making it suitable for indoor spaces where a clear warning is needed. The detector operates between 0°C and +50°C and tolerates relative humidity up to 95%RH without condensation. A low voltage signal is transmitted every 24 hours when the battery is under voltage, which helps with maintenance planning. The white casing allows it to fit unobtrusively into most interiors. This product is designed for use in homes, offices, rental properties, and similar indoor environments where a standalone or linked smoke alarm is required.

Features and Construction

The wireless smoke detector combines a battery-powered alarm with a wireless transmitter. It uses a DC9V 6F22/9V battery and operates on 433MHz, 1 527, and 330K frequencies. The alarm sound exceeds 80dB, and the device includes a low voltage warning system that sends a signal every 24 hours under continuous undervoltage. The white housing is the only colour option stated, and the unit is intended for indoor use within the specified temperature and humidity limits.

Material and Build

The source text specifies a white casing, but does not name the exact plastic or housing material. The unit is powered by a DC9V 6F22/9V stacked battery, which is a common type for smoke alarms. The quiet current is below 10uA, and the alarm current is below 100mA, indicating low standby power consumption. No further construction details such as housing thickness or mounting bracket material are provided. Buyers should check the product listing or packaging for additional material information if required.

Size and Practical Fit

No physical dimensions are given in the source text. The detector is described as white and suitable for indoor use, but its diameter, height, and weight are not stated. This means buyers cannot confirm exact ceiling coverage or fit from the available data. The operating temperature range of 0°C to +50°C and humidity tolerance of up to 95%RH provide some guidance on suitable indoor conditions, but the absence of dimensions should be noted before purchase.

Uses and Placement

This smoke detector is intended for indoor environments such as homes, offices, rental flats, and small commercial premises. Its wireless transmission allows it to send signals to compatible receivers or alarm panels up to 100 metres in open space. The loud 80dB alarm provides an audible warning, and the low voltage code transmission supports regular maintenance. It is not specified for outdoor use or for extreme temperatures outside the stated range.

Event or Professional Use

For landlords, property managers, or small business owners, this detector can be part of a simple wireless alarm setup. The 433MHz transmission and 100-metre open-space range mean it can be placed in a hallway or room while sending a signal to a central receiver. The low voltage code sent every 24 hours helps track battery status without manual checking. However, no information is given about compatibility with specific alarm panels or receivers, so buyers should verify compatibility before relying on the wireless link.

Everyday Home Use

In a typical home, the detector can be mounted in bedrooms, hallways, or living areas to provide an audible smoke warning. The 80dB alarm is loud enough to be noticed in adjacent rooms under normal conditions. The white casing blends with most ceilings and walls. The DC9V battery is widely available, and the low current draw in standby helps extend battery life. The device is not suitable for areas with condensation or temperatures outside 0°C to +50°C.

Benefits and Buying Value

The main practical benefits are the loud alarm, wireless signal transmission, and the low voltage warning system. The detector uses a standard 9V battery, which is easy to replace. The low standby current and the 24-hour low voltage code help reduce the chance of a dead battery going unnoticed. The white colour provides a neutral appearance. No price, warranty, or lifespan claims are made in the source text, so value should be judged on the stated specifications.

Reuse and Low Maintenance

The detector is designed around a replaceable DC9V 6F22/9V battery, so the unit can continue to be used after battery replacement. The quiet current below 10uA suggests low power draw in standby, which may help extend the interval between battery changes. The low voltage code transmission every 24 hours provides a maintenance reminder. No specific battery life or replacement interval is given, so users should follow the manufacturer's guidance and test the alarm regularly.

Why Choose This Product

This wireless smoke detector is a practical choice for buyers who need an audible smoke alarm with a 433MHz wireless signal and a low voltage warning feature. The 80dB alarm, 100-metre open-space transmission range, and 0°C to +50°C operating range are clearly stated. The white casing and 9V battery power supply are straightforward. The main limitations are the lack of stated dimensions, housing material, and certification details. Buyers who need those specifics should confirm them with the seller before purchase.
