Smoke and Carbon Monoxide Alarm 85 dB
Product description
A smoke and carbon monoxide alarm that brings two essential safety functions into one unit, with a clear digital LCD display for easier day to day checking. This Smoke & Carbon Monoxide Alarm with Digital LCD Display helps you monitor CO levels, and it also supports smoke detection for home and workspace use 🔎. Battery powered operation is designed to keep protection in place even if the power goes out, so you are not left waiting for the lights to come back.
If you want a straightforward combination alarm with user friendly controls, this is worth a close look. It includes a test and silence button for regular checks and temporary silencing when you need it, and it features an audible 85 decibel alarm to alert you quickly if danger is detected. According to the manufacturer, the CO sensing uses an electrochemical approach, aimed at accurate carbon monoxide detection, with a low battery warning indicator to help you stay on top of maintenance.

The essentials


This combination alarm is built to detect smoke and carbon monoxide in a single device, which can simplify your safety setup where you want less clutter and fewer separate units. The digital LCD display is designed to show carbon monoxide concentration levels in parts per million, in real time, so you can read what the alarm is sensing rather than relying only on an alarm sound. LED display information and ongoing monitoring help you understand what is happening, especially in situations where you want reassurance as well as warnings.

Day to day controls are kept simple. There is an easily accessible test and silence button, which makes it easier to carry out routine tests and to silence an alarm temporarily if it has been triggered by a brief event. Battery powered operation is a key practical point, because power cuts can happen, and you still need protection when they do 🏠. The low battery warning indicator is also useful for planning replacements before the device becomes inactive.
Key features



A clear digital LCD display shows CO concentration levels in parts per million, so you can check readings quickly. This is helpful if you want more than a general warning and prefer seeing a measured level. The loud alarm uses an 85 decibel sound, designed to grab attention promptly if carbon monoxide levels rise or if smoke is detected 🔔.
The alarm is supported by reliable CO sensors. According to the manufacturer, it uses advanced electrochemical sensors to detect and monitor carbon monoxide levels. For owners who want predictable upkeep, the low battery warning indicator provides an early signal so you are not caught out.

There is also a practical user interface designed for routine use. You can use the test and silence button to perform regular testing and temporarily silence alarms when you need to deal with a situation. The combination design also makes it a good fit for places where you want smoke and CO coverage without installing separate detectors for each hazard.


You may want to note that, as with all alarms, correct installation and regular testing are important to keep protection meaningful. It is also worth following the instructions supplied for your property type, particularly if you are fitting it in a garage or other outbuilding where conditions can be different.
