FABISENSE PTH-24D vs PTH-24E Plug-In CO and Gas Alarm Buying Guide Malaysia
FABISENSE PTH-24D vs PTH-24E Plug-In CO and Gas Alarm Buying Guide Malaysia
Content
The FABISENSE PTH-24D and PTH-24E are plug-in alarms with different gas detection functions. The PTH-24D detects carbon monoxide, while the PTH-24E adds combustible gas detection. Both models include temperature and humidity readings, a buzzer alarm and a 2.0-inch IPS display, according to the supplied manufacturer catalogue.
For buyers in Malaysia, selection should start with the gas you need to detect, followed by installation requirements, alarm performance and the correct plug configuration.

Choose PTH-24D for its listed CO detection function. Consider PTH-24E when combustible gas detection is also required, after confirming compatibility with the specific gas and installation.
FABISENSE PTH-24D Carbon Monoxide Alarm
The PTH-24D is presented as a carbon monoxide alarm with a numerical CO display.
Its listed functions include:
Carbon monoxide detection
Temperature display
Humidity display
Buzzer alarm
2.0-inch IPS screen
Replaceable plug configuration
The catalogue gives a CO range of 0999 ppm. However, the display range alone does not establish the alarm thresholds, response times or certification.
Before selection, request the model-specific manual and alarm performance documentation.
FABISENSE PTH-24E CO and Combustible Gas Alarm
The PTH-24E combines CO detection with a combustible gas indication.
The catalogue names the following combustible gases:
Methane - CH4
Ethane - C2H6
Propane - C3H8
Butane - C4H10
Its gas display is described using levels 14, with a reference to 8% CH4 LEL. The supplied page does not clearly explain how each level relates to gas concentration or alarm activation.
Confirm the gas calibration, sensitivity and alarm thresholds for the intended fuel. The reference to methane does not establish equivalent performance for propane or butane.
Understanding the Gas Display
The PTH-24E illustration shows a numerical CO reading and coloured gas level bars.
These displays should be interpreted separately:
CO in ppm indicates the displayed carbon monoxide concentration.
Gas level bars provide the manufacturer’s combustible gas indication. The supplied page does not establish a continuous numerical %LEL measurement.
Do not describe the PTH-24E as a 0100% LEL meter or assign gas concentrations to its coloured bars without supporting documentation.

The catalogue describes the housing as using flame-retardant materials, but does not state a material rating. This description does not establish explosion protection or intrinsic safety.
Clarifying the CO Accuracy Entry
The specification table labels “CO: 1 PPM” under accuracy.
This is insufficient to establish ±1 ppm measurement accuracy. Request clarification on whether the entry refers to display resolution or another specification.
Buyers should also ask for:
CO accuracy under defined conditions.
Sensor technology and service life.
Response time.
Alarm concentration and delay settings.
Calibration or functional test instructions.
Plug Configuration for Malaysia
The catalogue lists replaceable plugs, and the dimensions row refers to Australian, American and Chinese plug versions.
A Malaysia-compatible plug configuration is not confirmed on this page. Specify the required plug when requesting a quotation and obtain confirmation of the supplied version.
Also confirm whether the alarm has backup power. Battery backup and operation during a mains power failure are not stated in the supplied catalogue.
Installation Depends on the Gas and Product Instructions
A convenient wall socket is only one part of choosing an installation location.
For the PTH-24E, placement must account for the intended combustible gas and the manufacturer’s instructions. A combined detector requires particular attention because different gases may call for different installation considerations.
Before ordering, confirm:
The intended gas or fuel.
Recommended mounting position.
Permitted distance from appliances.
Environmental restrictions.
Whether the available socket is suitable for that position.
Follow the model-specific installation manual rather than choosing a position from the product photograph.
Applications for Malaysian Buyers
Homs and Residential Properties
Buyers considering CO or combustible gas alarms should first identify the intended detection requirement and request evidence of suitability for that use.
Rental Properties and Accommodation
Property managers in Selangor, Kuala Lumpur, Johor and Penang should check installation instructions, testing arrangements, sensor replacement intervals and any project-specific requirements.
Small Commercial Premises
For businesses considering the PTH-24E near fuel-using equipment, confirm gas compatibility, installation conditions and required alarm documentation before selection.
These catalogue descriptions do not establish suitability for industrial hazardous areas or confined-space entry.
Frequently Asked Questions
Does PTH-24D detect LPG?
Combustible gas detection is not listed for PTH-24D. It is presented as a CO alarm.
Does PTH-24E detect propane and butane?
The catalogue names both gases. Confirm the model’s sensitivity, alarm thresholds and suitability for the intended LPG application before purchase.
Does either model measure CO2?
CO2 measurement is not listed. Carbon monoxide and carbon dioxide are different gases.
Do these alarms connect to Wi-Fi?
Wi-Fi, Bluetooth and smartphone app functions are not listed on the supplied page.
Will the alarm work during a power failure?
Backup power is not specified. Obtain confirmation before relying on operation without mains power.
Are these certified residential CO alarms?
The supplied page does not state a residential CO alarm certification. Request the applicable certificate and verify that it covers the exact model supplied.
Can PTH-24E replace an industrial multi-gas detector?
The supplied specifications do not establish that capability. Oxygen and hydrogen sulphide detection, intrinsic safety and occupational exposure logging are not listed.
