FABISENSE PTH-258 Smart WiFi Carbon Monoxide Alarm Malaysia
FABISENSE PTH-258 Smart WiFi Carbon Monoxide Alarm Malaysia
Content
The FABISENSE PTH-258 Smart Carbon Monoxide Alarm combines a digital CO display, audible buzzer, temperature and humidity readings, and Tuya app connectivity. Its plug-in design includes battery backup provision for short-term use during a mains power interruption.
For buyers in Malaysia, the main selection points are the alarm specifications, WiFi compatibility, backup operation and supplied plug configuration. The catalogue identifies this model as a UL 2034 version; supporting documentation should be checked against the actual unit supplied.
Carbon Monoxide Monitoring with a Local Display
The PTH-258 has a listed CO measuring range of 0-1000 ppm, with a resolution of 1 ppm.
Its stated CO accuracy is ±5 ppm or ±10%, whichever is greater. Resolution describes the display increment, while accuracy describes the stated measurement tolerance. A 1 ppm resolution therefore does not mean ±1 ppm accuracy.
The front display shows CO concentration together with temperature and relative humidity. This allows users to view the readings directly at the detector without opening an app.
The product also features a buzzer, test button and status indication. The illustrated housing identifies green for power, yellow for fault and red for alarm.
WiFi and Tuya App Connectivity
The catalogue advertises WiFi connectivity through the Tuya app, with features including:
CO monitoring information
Alarm alerts
Historical data
Trend curves
Temperature and humidity readings
These functions can help users review readings and changes over time. The illustrated app also shows alarm records.
Before ordering, confirm the supported WiFi frequency, app compatibility, notification settings and historical data retention. These details are not specified on the supplied catalogue page.
Remote access also depends on the relevant power, network and app conditions. Buyers should confirm how the detector and its local alarm behave when WiFi or internet access is unavailable.
Plug-In Power with AA Battery Backup
The PTH-258 specification lists 100-240 V, 50/60 Hz mains power, an interchangeable plug and two 1.5 V AA alkaline batteries.
The catalogue describes the arrangement as plug-in operation with short-term backup use. It does not state a guaranteed backup duration or whether every connected function remains available on batteries.
For a Malaysian installation, confirm:
The plug supplied with the unit
Whether the AA batteries are included
Expected backup operating time
Functions available during battery operation
Battery replacement and low-battery indication
This model lists AA alkaline batteries. It should not be described as having a rechargeable lithium battery based on specifications from another FABISENSE model.

The temperature measurement range and the complete device's working temperature are different specifications. Use the stated 0°C to 40°C working temperature when assessing installation suitability.
Choosing the PTH-258 for Your Property
Homes and Living Spaces
The PTH-258 is presented as a home CO alarm. Its local display suits users who want to see readings at the installation point, while app connectivity provides an additional way to access monitoring information.
Select the installation position according to the manufacturer's manual. Socket convenience alone should not determine detector placement.
Rental Properties and Accommodation
For landlords and accommodation operators in Selangor, Kuala Lumpur and other parts of Malaysia, app-connected monitoring may support routine oversight.
Before installing several units, confirm account access, device naming, notification arrangements and maintenance responsibilities. Each detector should have a recorded installation date and a defined checking schedule.
Buyers Requiring Connected Monitoring
The PTH-258 is relevant when WiFi access, historical readings and trend viewing are part of the requirement.
If your priority is operation without a mains supply, compare the specified battery arrangements and runtime with a dedicated battery-powered model before choosing.
Understanding the UL 2034 Catalogue Reference
The supplied page labels the PTH-258 as a UL 2034 version. This should be presented as the manufacturer's catalogue designation rather than an independently verified certification claim.
Where compliance documentation is required, request evidence identifying the exact model, applicable standard edition and supplied configuration.
Also confirm the alarm thresholds, response times, audible alarm specification and product service life. These are not stated on the supplied page, and the CO measuring range alone does not establish alarm behaviour.
Frequently Asked Questions
Does the PTH-258 detect carbon dioxide?
CO2 detection is not listed. The catalogue specifies carbon monoxide, temperature and humidity monitoring.
Does it detect LPG or methane?
Combustible gas detection is not listed for the PTH-258. Buyers requiring gas monitoring should request a model documented for the intended gas.
Does the PTH-258 connect to Tuya?
Yes. The catalogue advertises WiFi connectivity and Tuya app integration. Confirm network requirements and available app functions before purchase.
Does it have battery backup?
The specification lists two 1.5 V AA alkaline batteries, and the catalogue describes short-term backup use. Backup runtime is not specified.
Is the PTH-258 rechargeable?
The supplied page lists AA alkaline batteries and does not advertise battery charging. Do not assume the plug-in supply charges the batteries.
Can historical readings be exported?
History data and trend curves are advertised, but export capability and storage duration are not specified. Confirm these functions if records are required.
Does the test button verify CO measurement accuracy?
The test button should be used according to the operating manual. A successful button test should not be treated as a calibration result or proof of measurement accuracy.
