3. Close the battery compartment cover securely. The detector will emit a short beep and the green LED will flash, indicating power-on.

4.2 Mounting and Placement:

For optimal performance and safety, follow these guidelines for placement:

• Install the detector at least 1.5 meters (5 feet) away from fuel-burning appliances to avoid false alarms.
• Mount the detector on a wall, approximately 1.5 meters (5 feet) from the floor, or at breathing level.
• Avoid placing the detector in direct sunlight, near vents, fans, or in areas with high humidity.
• Use the provided screws and wall plugs to securely mount the detector.

2. Register or log in to your account.
3. Ensure your smartphone is connected to a 2.4GHz Wi-Fi network.
4. Open the app and tap "+" to add a device.
5. Select "Security & Sensor" -> "CO Detector (Wi-Fi)".
6. Follow the in-app instructions to put the detector into pairing mode (usually by pressing the test button three times quickly). The yellow LED may flash rapidly.
7. Confirm the indicator is flashing rapidly in the app and enter your Wi-Fi password.
8. The app will search for and connect to the device. Once connected, you can rename the device and access its features.

5. Operating Instructions

5.1 Self-Test:

It is recommended to test your CO detector weekly to ensure proper operation.

• Press and hold the "Test/Hush" button for approximately 3 seconds.
• The detector will emit a series of loud beeps, and the red LED will flash. This indicates the alarm and sensor are functioning correctly.
• Release the button. The detector will return to normal monitoring mode.

5.2 Understanding Alarms:

• CO Alarm: When carbon monoxide is detected at dangerous levels, the red LED will flash rapidly, and the alarm will sound continuously.
• Low Battery Warning: The yellow LED will flash periodically, and the detector will chirp every 60 seconds, indicating that the batteries need to be replaced.
• Fault Warning: The yellow LED will flash, and the detector will chirp at irregular intervals, indicating a malfunction. Refer to the troubleshooting section.

5.3 Silencing the Alarm (Hush Feature):

In case of a nuisance alarm (e.g., from temporary high CO levels due to cooking), you can temporarily silence the alarm.

• Press the "Test/Hush" button briefly.
• The alarm will silence for a short period (e.g., 5-10 minutes), allowing the air to clear. If CO levels remain high, the alarm will reactivate.
• Note: Do not use the hush feature if you suspect a real CO leak. Evacuate immediately.

5.4 App Features:

• Real-time Monitoring: View the current status of your detector, including battery level and connection status.
• Notifications: Receive instant alerts on your smartphone if a CO alarm is triggered or if the battery is low.
• Remote Test: Initiate a self-test of the detector remotely through the app.
• Alarm History: Review past alarm events and device status changes.
• Remote Mute: Silence the alarm remotely via the app (use with caution).

6. Maintenance

6.1 Regular Cleaning:

• Clean the detector regularly (at least once a month) to prevent dust buildup from affecting sensor performance.
• Use a soft, damp cloth to wipe the exterior. Do not use cleaning sprays or solvents.
• Do not paint the detector.

6.2 Battery Replacement:

When the low battery warning sounds (yellow LED flashes and chirps every 60 seconds), replace the batteries immediately.

1. Open the battery compartment.
2. Remove the old C batteries.
3. Insert new C batteries, ensuring correct polarity.
4. Close the compartment. The detector will beep and the green LED will flash, indicating normal operation.

6.3 End of Life:

The HEIMAN WS-725ES has a 10-year lifespan. After 10 years from the date of manufacture (indicated on the device), the detector will signal its end-of-life by chirping periodically with the yellow LED flashing, even with new batteries. At this point, the detector must be replaced.
