1. Uvod
Thank you for choosing the Protmex PTH-24E 4-in-1 Carbon Monoxide and Gas Detector. This device is designed to provide real-time monitoring of carbon monoxide (CO) and combustible gas levels, along with temperature and humidity, to enhance safety in your home or while traveling. Please read this manual carefully before use to ensure proper operation and safety.
2. Varnostne informacije
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. Combustible gases can also pose serious risks. This detector is an important safety device, but it is not a substitute for proper maintenance of fuel-burning appliances or ventilation systems. Always follow local regulations and safety guidelines.
- Ne blokirajte prezračevalnih odprtin na napravi.

4. Nastavitev
The Protmex PTH-24E is designed for easy, plug-and-play installation.
- Razpakiraj: Previdno vzemite detektor iz embalaže.
- Izberite lokacijo: Select a suitable location for the detector. For CO detection, place it near sleeping areas and on every level of your home. For gas detection, place it near gas-burning appliances (e.g., kitchen, fireplace). Ensure it is not obstructed by furniture or curtains.
- Plug In: Insert the detector directly into any standard 110V-220V electrical outlet. The device will power on automatically.
- Začetna kalibracija: The device will perform an initial self-test and calibration upon first power-up. Allow a few minutes for the readings to stabilize.
Replaceable Plug:
The device features a replaceable plug, allowing it to be used with different outlet types. To change the plug, press the quick-release button, rotate the current plug to unlock, and replace it with the desired plug type. Ensure it locks securely into place.

5. Navodila za uporabo
The PTH-24E features three intuitive buttons for various functions:

Figure 3: Easy-to-Use Controls. This diagram illustrates the functions of the three buttons on the device for self-testing, unit toggling, alarm control, screen orientation, brightness, and gas sensitivity.
- "U" Button (Top):
- Short Press: Initiates a self-test of the device.
- Long Press: Toggles between Fahrenheit (°F) and Celsius (°C) for temperature display.
- Gumb za brenčanje (desni):
- Short Press: Turns the alarm sound on or off.
- Long Press: Flips the screen display 180 degrees, useful if the outlet orientation is inverted.
- Gumb za svetlost zaslona (levi):
- Short Press: Adjusts the screen brightness.
- Long Press: Switches between Gas Sensitivity 1 (S1) and Gas Sensitivity 2 (S2).
Verifying CO Detector Functionality:
To verify the CO detector is working properly, you can perform a simple test:
- Place a lit cigarette (or a source of CO, such as a small amount of smoke from a match) over the detector's back vent.
- Within 1-2 minutes, you should observe the CO value increase on the display.
- When the carbon monoxide concentration exceeds 50 PPM, the CO detector will sound an alarm. The CO value can display up to 999 PPM. This confirms the detector is working correctly.

6. Prikaz informacij
The large LCD screen provides clear, real-time data:
- CO PPM: Prikazuje koncentracijo ogljikovega monoksida v delcih na milijon.
- PLIN: Indicates the level of combustible gas detected. This is often represented by a colored bar or numerical value.
- Temperatura: Shows the ambient temperature in either Celsius or Fahrenheit.
- Vlažnost: Displays the relative humidity percentage.
- Opozorilne ikone: Visual indicators for alarms (e.g., bell icon) and status (e.g., green for safe, yellow/orange for caution, red for danger).

7. Vzdrževanje
To ensure optimal performance and longevity of your detector:
- Redno čiščenje: Zunanjost detektorja nežno obrišite z mehko krpoamp krpo. Ne uporabljajte močnih kemikalij ali abrazivnih čistil.
- Prezračevalne odprtine naj bodo proste: Ensure that the ventilation openings on the device are free from dust, debris, or obstructions.
- Izogibajte se ekstremnim razmeram: Do not expose the detector to direct sunlight, high humidity, or extreme temperatures outside its operating range (14°F to 122°F / -10°C to 50°C).
- Redno testirajte: Perform the self-test function weekly or monthly to confirm proper operation.
8. Odpravljanje težav
| Težava | Možen vzrok | rešitev |
|---|---|---|
| Alarm sounds frequently without apparent cause. | High CO/Gas levels, sensor malfunction, or false alarm. | Immediately ventilate the area and evacuate. If safe, check for gas leaks. If alarms persist without a clear cause, contact emergency services or a qualified technician. |
| Zaslon je prazen ali se ne odziva. | No power, device malfunction. | Ensure the device is securely plugged into a working outlet. Try a different outlet. If the issue persists, contact customer support. |
| Netočne meritve temperature/vlažnosti. | Device placed near heat/cold source, blocked sensors. | Relocate the device away from direct heat sources, vents, or windows. Ensure sensors are not obstructed. |
