FABISENSE PTH-253 Series Plug-In CO, Gas and Smoke Detector Buying Guide Malaysia
FABISENSE PTH-253 Series Plug-In CO, Gas and Smoke Detector Buying Guide Malaysia
Content
The FABISENSE PTH-253 series offers five configurations for different detection requirements. Choose PTH-253A for CO, PTH-253B for CO and combustible gas, PTH-253C for CO and smoke, PTH-253D for CO, smoke and combustible gas, or PTH-253E for CO and CO2.
According to the supplied manufacturer catalogue, all five models also include temperature, humidity, a buzzer alert and a replaceable plug. The power specification lists 100–240 V AC operation with a built-in 1000 mAh lithium battery.
FABISENSE PTH-253 Model Comparison
Select the complete model number before ordering. The shared housing does not mean that every version includes all detection functions.

Temperature, humidity and a buzzer alert are listed across the series.
PTH-253A - Carbon Monoxide Detection
The FABISENSE PTH-253A provides the CO configuration, with a listed 0–1000 ppm range and 1 ppm display resolution.
Its screen also displays temperature and humidity.
The catalogue does not provide CO measurement accuracy, sensor technology or response time. A 1 ppm resolution does not establish ±1 ppm accuracy.
Before selecting it for a specified alarm requirement, request the model’s alarm thresholds, activation times and supporting certification.
PTH-253B - CO and Combustible Gas Detection
The PTH-253B adds combustible gas detection to the CO function.
The catalogue describes the gas indication as levels 1–3, with Level 3 referenced to 15% CH4 LEL.
This entry does not establish a continuous numerical %LEL measurement range or equivalent performance for every fuel.
Confirm:
Supported gases and calibration gas
Meaning of each indicated level
Alarm activation thresholds
Response time
Placement requirements
Do not assume LPG, propane or butane compatibility solely from the methane reference.
PTH-253C - CO and Smoke Detection
The PTH-253C combines CO and smoke detection.
Smoke indication is listed as levels 1–3, but the page does not define the sensing method, sensitivity or level thresholds.
Confirm the exact model’s smoke alarm documentation before choosing it for a fire detection requirement. A smoke function listed in a catalogue does not establish certified smoke alarm performance.
PTH-253D - CO, Smoke and Combustible Gas
The PTH-253D includes the broadest combination of listed detection functions in this series:
Carbon monoxide
Combustible gas
Smoke
Temperature
Humidity
Installation requires particular attention because the appropriate position depends on the intended detection functions and manufacturer instructions.
Confirm that the proposed socket location is suitable for the complete application. Product photographs should not be used as installation instructions.
PTH-253E - Combined CO and CO2
The PTH-253E lists:
ParameterCatalogue rangeCO0–1000 ppmCO2400–5000 ppm
This configuration may interest buyers who require both gases on one instrument.
The table places ±(50 ppm + 5%) in the resolution row for CO2. This resembles an accuracy expression, but its definition and percentage basis are unclear.
Request a corrected CO2 specification covering resolution, accuracy and test conditions. The supplied page does not identify the CO2 sensor technology.

The housing is described as using flame-retardant materials. No material rating or hazardous-area approval is stated.
Audible and Visual Alarm Functions
The promotional text advertises 85 dB audible and visual alarms.
However, it does not state the measurement distance, test conditions or whether the figure applies to every configuration. Confirm these details where sound output is a purchasing requirement.
Also request information on alarm delays, silencing, reset behaviour, sensor faults and end-of-life indications.
Mains Power and Built-In Battery
The series lists a replaceable plug and built-in battery.
Before relying on battery operation, confirm:
Runtime for the selected model
Automatic changeover during power failure
Alarm availability without mains power
Charging time
Battery replacement arrangements
Battery capacity alone does not establish backup duration.
For Malaysia, specify the required plug configuration in the quotation and confirm the supplied version.
Choosing a PTH-253 Detector in Malaysia
For homes, rental properties and facilities in Selangor, Kuala Lumpur, Johor and Penang, start with the actual detection requirement.
PTH-253A provides the listed CO-only gas configuration.
PTH-253B adds combustible gas detection.
PTH-253C adds smoke detection.
PTH-253D combines CO, smoke and combustible gas.
PTH-253E combines CO and CO2.
Where a project specifies particular alarm approvals or installation criteria, check those requirements against documents for the exact model supplied.
Frequently Asked Questions
Does every PTH-253 model measure CO2?
No. CO2 measurement is listed for PTH-253E.
Which model detects CO, smoke and combustible gas together?
The PTH-253D lists all three functions.
Can PTH-253B or PTH-253D detect LPG?
The page includes a methane-based reference but does not establish LPG performance. Confirm suitability for 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 it operate during a power failure?
A built-in battery is listed. Automatic changeover, runtime and alarm behaviour require confirmation.
Is the 85 dB alarm figure independently verified?
The figure appears in the manufacturer’s promotional text. Supporting test conditions and documentation are not supplied on this page.
How does PTH-253 differ from PTH-252?
The supplied pages list similar configurations and several matching specifications. Request a manufacturer comparison to establish differences in hardware, sensors, firmware and mounting before treating either series as an upgrade.
