5. Setup
5.1 Battery Installation
- Remove the mounting bracket from the back of the detector by twisting it counter-clockwise.
- Insert the three AA batteries into the battery compartment, ensuring correct polarity (+/-). The detector will automatically power on and beep briefly.
- Reattach the mounting bracket by aligning it and twisting clockwise until secure.

5.2 Mounting the Detector
Choose a suitable location for your detector, typically on a ceiling or high on a wall, away from corners and obstructions. Avoid placing it near windows, doors, or vents where drafts might interfere with detection.
- Once batteries are installed, select your desired mounting location.
- Use the mounting bracket as a template to mark the positions for the two screw holes on the wall or ceiling.
- Drill pilot holes at the marked positions. Insert the wall anchors if drilling into drywall.
- Secure the mounting bracket to the wall or ceiling using the provided screws.
- Align the detector unit with the mounted bracket and twist it clockwise until it locks securely into place.

6. Operating Instructions
6.1 Digital Display and LED Indicators
The detector features a digital display and three LED indicator lights:
- Digital Display: Shows real-time levels of carbon monoxide (CO) or smoke. In standby mode, the display will be blank to conserve battery, but the unit remains active.
- Green LED (Power): Flashes approximately every 60 seconds when the detector is in standby mode, indicating normal operation.
- Red LED (Alarm): Flashes with an audible beep during a CO alarm, a smoke alarm, or a low battery warning.
- Yellow LED (Fault): Illuminates to indicate a malfunction within the unit.

6.2 Test Function
Press the 'TEST' button on the front of the detector to verify its functionality. The unit will emit a loud alarm sound and the red LED will flash. The digital display will show '000' or a test sequence. This confirms that the alarm and internal circuitry are working correctly.
Video 3: Testing the Detector. This video demonstrates how to use the test button to ensure the detector is functioning properly, including the alarm sound and display response.
6.3 Alarm Thresholds and Sound
The detector is designed to trigger an alarm when carbon monoxide levels reach between 70 ppm and 700 ppm, or when smoke is detected. The alarm sound level is greater than 85 dB at 1 meter, ensuring it is audible throughout your home.
Figure 6: CO Alarm Thresholds. This diagram visually represents various CO concentration levels and indicates that levels between 70 ppm and 700 ppm will activate the alarm.
7. Maintenance
7.1 Battery Replacement
When the batteries are low, the detector will emit a beep and the red LED will flash. Replace all three AA batteries immediately with new ones to ensure continuous protection. Refer to section 5.1 for battery installation steps.
7.2 Cleaning
Regularly clean the exterior of the detector to prevent dust and debris from accumulating, especially around the air inlets. Use a soft, damp cloth to wipe the surface. Do not use cleaning sprays, solvents, or harsh chemicals, as these can damage the unit or interfere with its sensors.
7.3 Regular Testing
Test your detector at least once a month by pressing the 'TEST' button. This verifies that the alarm and sensors are functioning correctly. If the unit does not respond as expected during a test, refer to the troubleshooting section.
8. Troubleshooting
If you encounter any issues with your Soewolit PTH-913 detector, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| Detector does not power on | Batteries incorrectly installed or dead. | Check battery polarity; replace with new AA batteries. |
| Red LED flashes and beeps (low battery) | Batteries are low. | Replace all three AA batteries immediately. |
| Yellow LED illuminates (fault) | Internal malfunction. | Press the 'TEST' button to reset. If the fault persists, contact customer support. |
| False alarms | Dust, high humidity, or cooking fumes near the detector. | Clean the detector. Relocate the detector if it's frequently exposed to cooking fumes or steam. |
| Alarm sounds without visible smoke or CO reading | Potential presence of invisible CO or smoke, or a sensor issue. | Evacuate immediately and call emergency services. Do not assume it's a false alarm. |
