FABISENSE PTH-252 Series CO, Gas and Smoke Detector Buying Guide Malaysia
FABISENSE PTH-252 Series CO, Gas and Smoke Detector Buying Guide Malaysia
Content
The FABISENSE PTH-252 series offers five detector configurations with different combinations of carbon monoxide, combustible gas, smoke and carbon dioxide detection. According to the supplied manufacturer catalogue, all models also include temperature, humidity, a buzzer alert and a replaceable plug.
The series combines 100–240 V AC power with a built-in 1000 mAh lithium battery, providing plug-in and portable power options. Confirm battery runtime and operating behaviour for the exact model before purchase.
FABISENSE PTH-252 Model Comparison
Choose the model according to the detection functions required. The five versions share a similar appearance but have different configurations.

Temperature, humidity and a buzzer alert are listed across all five models.
PTH-252A - CO Detection with Temperature and Humidity
The FABISENSE PTH-252A is the simplest configuration in this series.
Its listed functions include:
CO detection
Temperature display
Humidity display
Buzzer alert
Replaceable plug
The catalogue gives a CO measurement range of 0–1000 ppm and a 1 ppm resolution.
Choose this configuration when CO is the required gas parameter, after confirming alarm performance and suitability for the intended installation.
PTH-252B - CO and Combustible Gas Detection
The PTH-252B adds combustible gas detection to the CO function.
The catalogue describes its gas indication as levels 1–3, with Level 3 referenced to 15% CH4 LEL.
This does not establish a continuous numerical gas measurement range. Before selecting it, confirm:
Supported combustible gases
Calibration gas
Meaning of each displayed level
Alarm thresholds and response times
Installation requirements for the intended fuel
The methane reference should not be used to assume equivalent performance for propane, butane or an LPG mixture.
PTH-252C - CO and Smoke Detection
The PTH-252C combines CO and smoke detection with temperature and humidity readings.
Smoke indication is listed as levels 1–3. The supplied page does not define these levels, identify the smoke sensing method or provide smoke alarm sensitivity specifications.
Request model-specific alarm documentation before choosing this configuration for a fire detection requirement. A listed smoke function alone does not establish certified smoke alarm performance.
PTH-252D - CO, Smoke and Combustible Gas Detection
The PTH-252D offers the broadest combination of listed alarm parameters in this series:
Carbon monoxide
Smoke
Combustible gas
Temperature
Humidity
However, a combined detector still requires a suitable installation position for its intended functions.
Confirm the manufacturer’s placement instructions for the exact application. An available power socket may not be the appropriate sensing location for every parameter.
PTH-252E - Combined CO and CO2 Detection
The PTH-252E combines carbon monoxide and carbon dioxide measurement.
The catalogue lists:
ParameterListed rangeCO0–1000 ppmCO2400–5000 ppm
This configuration may interest buyers who need both gas readings in one device.
The table places a CO2 expression involving 50 ppm and 5% in the resolution row. This is not a clear CO2 resolution specification. Request a corrected datasheet confirming resolution, accuracy and the basis of the percentage term.
The supplied page does not identify the CO2 sensor technology, so NDIR sensing should not be assumed.

CO accuracy is not stated on the supplied page. A 1 ppm display resolution should not be presented as ±1 ppm accuracy.
The housing is described as using flame-retardant materials, but no material rating or hazardous-area approval is provided.
Plug-In and Battery Operation
The PTH-252 series is presented as supporting both mains power and a built-in battery.
Before ordering, confirm:
Battery runtime
Automatic changeover during a power failure
Functions available in battery mode
Charging time
Low battery warnings
Battery replacement arrangements
The battery capacity alone does not establish how long the detector will continue operating without mains power.
Selecting a Plug for Malaysia
The catalogue lists a replaceable plug, but does not identify the plug versions available.
Specify the required Malaysia-compatible plug configuration in the quotation. Confirm the supplied plug and applicable product documentation before purchase.
For property owners and facilities teams in Selangor, Kuala Lumpur, Johor and Penang, also check whether the intended socket location meets the manufacturer’s installation requirements.
Alarm Performance and Installation
All five models list a buzzer alert. The page does not provide complete details on alarm thresholds, activation delays, sound output or fault indications.
For a defined alarm application, request documentation covering:
Alarm activation behaviour
Sensor service life
Testing and maintenance
Fault and end-of-life warnings
Placement instructions
Applicable certification for the exact model
Select the detector using both its measurement functions and its documented alarm performance.
Frequently Asked Questions
Which PTH-252 model detects CO only?
The PTH-252A lists CO as its gas detection function, alongside temperature and humidity.
Which model combines CO, smoke and combustible gas?
The PTH-252D lists all three functions.
Which model measures CO2?
CO2 measurement is listed for PTH-252E.
Can PTH-252B or PTH-252D detect LPG?
The page provides a methane-based LEL reference but does not establish LPG performance. Confirm compatibility with the intended fuel.
Does the series support Wi-Fi or Tuya Smart?
Wi-Fi, Bluetooth and app connectivity are not listed on the supplied page.
Will the detector work during a power failure?
A built-in battery is listed. Confirm automatic changeover, runtime and alarm operation during battery use.
Can the smoke versions replace a specified fire alarm?
The catalogue alone does not establish that suitability. Check the required certification and installation criteria against the exact model’s documents.
