FABISENSE PTH-242 Series CO, Gas and Smoke Detector Comparison Malaysia
FABISENSE PTH-242 Series CO, Gas and Smoke Detector Comparison Malaysia
Content
The FABISENSE PTH-242 series offers five detector configurations combining carbon monoxide monitoring, temperature, humidity and additional gas or smoke functions, depending on the model.
For buyers in Malaysia, the first step is choosing the correct configuration. The PTH-242A, PTH-242B, PTH-242C, PTH-242D and PTH-242E share a similar design, but their detection capabilities differ.
The series features plug-in and portable operation, a built-in lithium battery, a colour display and a replaceable plug.
Which PTH-242 Model Should You Choose?

CO, CO2, combustible gas and smoke are separate detection functions. Select the model according to the actual application rather than assuming every PTH-242 unit detects all four.
Carbon Monoxide Measurement Across the Series
All five models list a CO measurement range of 0-1000 ppm, with 1 ppm resolution.
Resolution describes the smallest displayed increment. It does not establish measurement accuracy, alarm response time or the concentration at which the alarm activates.
The supplied catalogue does not provide a separate CO accuracy specification. Buyers requiring documented performance should request the full manual and relevant test documentation.
PTH-242B and PTH-242D: Combustible Gas Indication
The PTH-242B and PTH-242D add combustible gas detection.
The catalogue describes three gas indication levels, LV1-LV3, with LV3 referenced to 15% CH4 LEL.
This is a level-based indication. The supplied page does not establish a continuous numerical combustible gas reading in ppm or define every level boundary.
Before selecting either model, confirm:
The gases supported by the supplied version.
The calibration gas.
The meaning of each indication level.
The alarm thresholds and response times.
The installation requirements for the intended gas.
The methane reference should not be treated as confirmation of identical performance for every combustible gas.
PTH-242C and PTH-242D: Smoke Detection
The PTH-242C and PTH-242D include smoke detection, described in the specification as LV1-LV3.
The catalogue does not identify the smoke sensor technology, sensitivity test method or applicable smoke-alarm certification.
For projects specifying a compliant fire or smoke alarm, check the exact certification and installation requirements before choosing the product. A listed smoke-detection function alone does not establish suitability for a regulated fire alarm installation.
PTH-242E: Combined CO and CO2 Monitoring
The PTH-242E combines:
CO: 0-1000 ppm.
CO2: 400-5000 ppm.
Temperature and humidity monitoring.
The CO2 entry shows ±(50 ppm + 5%) under the catalogue's “Resolution” row. This is an accuracy-style expression rather than a resolution value. Confirm its definition and the actual CO2 display resolution with the manufacturer.
The supplied page does not identify the CO2 sensor technology, so an NDIR sensor should not be assumed.
The PTH-242E does not list combustible gas or smoke detection.
Shared Display and Environmental Specifications

The display brings the supported readings together in one interface. For facilities teams or property owners, this can make local checks easier, provided the correct model has been selected.
The catalogue does not specify an ingress-protection rating or hazardous-area approval. Confirm environmental suitability before using the detector in damp, dusty or industrial locations.
Plug-in Power and Built-in Battery
The PTH-242 series lists 100-240 V AC, 50/60 Hz power, a replaceable plug and a built-in 1000 mAh lithium battery.
This arrangement supports the advertised plug-in and portable use. However, battery capacity alone does not establish operating duration.
Before ordering, confirm the Malaysian plug configuration, charging time and expected runtime for the selected model. Also check whether every detection and alarm function remains active during a mains power interruption.
Follow the manufacturer's placement instructions. Socket convenience should not determine the sensing location by itself.
Audible and Visual Alarm Functions
The promotional panel advertises an 85 dB audible and visual alarm. The supplied page does not state the measurement distance, test conditions or alarm timing.
Request the model-specific alarm information, including:
Trigger thresholds.
Activation delays.
Test and mute functions.
Low-battery indication.
Sensor fault and end-of-life indications.
These details help establish whether the detector matches the intended monitoring requirement.
Choosing a Detector for Malaysian Properties
For homes and offices in Puchong, Selangor and Kuala Lumpur, begin by identifying the required measurement: CO, combustible gas, smoke or CO2.
For accommodation, managed properties and facilities in Johor or Penang, also consider how detectors will be installed, tested and maintained across multiple rooms.
Where the project requires certified alarms, documented inspection results or integration with a building system, include those requirements in the enquiry. The supplied catalogue does not establish WiFi, app notifications, data logging or building-system connectivity for this series.
Frequently Asked Questions
Does every PTH-242 model detect combustible gas?
No. Combustible gas detection is listed for the PTH-242B and PTH-242D.
Which models detect smoke?
The PTH-242C and PTH-242D list smoke detection.
Which model measures CO2?
The PTH-242E lists a CO2 range of 400-5000 ppm alongside CO monitoring.
Does the PTH-242D measure CO2?
CO2 measurement is not listed for the PTH-242D. Its additional functions are combustible gas and smoke detection.
Can the detector operate without mains power?
The catalogue lists a built-in battery and portable operation. Confirm runtime and supported functions on battery power for the selected model.
Is the 1 ppm CO resolution the same as accuracy?
No. Resolution describes the displayed increment. CO accuracy requires a separate specification.
Can it send an alarm to a phone?
The supplied page does not list wireless connectivity or remote notifications.
