X-Sense XH02-M Heat alarm, 7-year battery

A Wi‑Fi heat alarm can be a straightforward way to strengthen home safety where fast temperature rises matter. The X-Sense XH02-M heat alarm uses class A1 heat sensing so it can detect a sudden temperature increase, without relying on smoke detection. Pair it with the required SBS50 base station and you can use the X-Sense Home Security app to receive alerts wherever you are, including push notifications for key events like alarms and low battery.

This model is built around an integrated 7-year sealed battery designed to reduce the hassle of frequent battery changes. It also includes easy setup via the test and silence process, plus options to test or mute through the app, which can make day to day management less disruptive. If you want heat-specific detection that avoids nuisance triggers from things like cooking vapours, this is worth considering as part of a wider connected setup.

The essentials

The X-Sense Wi‑Fi Heat Alarm with 7-Year Sealed Battery and Easy Setup, XH02-M is designed to work as an add-on in a compatible X-Sense home security setup. The alarm connects to the SBS50 base station, which is required, so it is not a standalone device. Once connected, it can support a larger system by adding up to 50 devices in total, which helps if you are building coverage room by room.

Heat alarms are particularly useful in places where smoke sensors may be more prone to nuisance activations. This one uses a sensitive NTC thermistor to detect either a rapid temperature rise or static temperatures in the range of 54 C to 65 C, according to the manufacturer. It is not triggered by smoke, dust, or cooking fumes, which can reduce the need to repeatedly silence alarms during everyday activities.

You also get app based monitoring with free push notifications. Through the X-Sense Home Security app, you can receive real time alerts for events such as a heat alarm, low battery, failures, and more. When the danger has passed, the app can notify you as well, helping you stay informed without constantly checking the device.

Key features

A major practical benefit of this alarm is the integrated 7-year sealed battery. As described by the manufacturer, it is designed with low energy consumption and tamper resistant construction, so you can expect long term operation without regular battery swapping. In addition, it is designed to keep providing protection 24/7 even if the power is lost, which matters if you want peace of mind during outages.

Setup is designed to be simple. You connect the XH02-M to the SBS50 base station using the device test and silence button, then you can add it to your app controlled system. For ongoing day to day control, you can use the test or silence function either by touching the button on the unit or through the X-Sense Home Security app. There is also mention of remote control operation using an X-Sense remote, which is sold separately, so you can avoid needing a ladder when testing.

Sharing within the household is supported through the app. With device sharing enabled in the X-Sense Home Security app, you can share security devices with family members so shared users can check history, receive push notifications, and silence devices when needed. That can be useful if multiple people manage the home, especially when you want everyone to respond appropriately.

It’s a good fit if you prefer heat based detection rather than smoke sensing, and you want connected notifications in a phone app. It makes sense if your goal is clearer alerts for fast temperature changes, and you want fewer nuisance triggers from everyday cooking fumes, dust, or vapours.

What to know before buying

Before purchasing the XH02-M, make sure you have the required SBS50 base station, because this alarm is an accessory that connects to it. The system is designed for expansion, with the ability to add up to 50 devices in total, so it can work well if you plan a multi device home setup. Also note that this is a heat alarm, not a smoke alarm, so it will not be activated by smoke, dust, or cooking fumes.

In practical terms, the app is a central part of the experience. You can test and silence the alarm using the app, which can help if you ever need to manage an alert without approaching the device. Shared users can also receive notifications and check history, so the system can be easier to manage across a household.

It’s not for you if you need a smoke detection alarm for general smoke driven alerts, since this model is specifically built around heat detection. It might not be a great match if you do not want to use the X-Sense Home Security app for push notifications and device control.
