Safety Information
Always adhere to the following safety guidelines:
- Do not paint the smoke detector. Paint can clog the sensing chambers and prevent the alarm from operating correctly.
- Do not install in areas with high humidity, excessive dust, or near sources of combustion (e.g., kitchens, garages, bathrooms) to avoid false alarms.
- Test the smoke detector weekly to ensure proper function.
- Never ignore a smoke alarm. Investigate the cause and take appropriate action immediately.
- Keep the device clean and free from obstructions.
Product Overview
The HEIMAN Interconnected Wireless Smoke Detector features advanced photoelectric sensing technology and a 10-year sealed lithium battery for long-lasting, reliable protection. It is designed for easy installation and can wirelessly interconnect with up to 40 other compatible HEIMAN smoke detectors, ensuring that when one alarm sounds, all connected alarms will also sound.

Setup
1. Unpacking
Carefully remove the smoke detector and all accessories from the packaging. Verify that all components are present: smoke detector unit, mounting bracket, screws, and anchors.
2. Battery Activation
The smoke detector comes with a pre-installed 10-year lithium battery. To activate the battery, simply remove the battery isolation tab (if present) or twist the detector onto its mounting bracket. The detector will emit a short beep to indicate activation.
3. Mounting Location
Choose a central location on the ceiling or high on a wall, away from corners, vents, and direct sunlight. For optimal protection, install smoke detectors in every sleeping area and on every level of your home, including the basement.
4. Mounting the Detector
Use the provided screws and anchors to securely attach the mounting bracket to the chosen location. Once the bracket is installed, align the smoke detector with the bracket and twist it clockwise until it locks into place. Ensure it is firmly attached.
5. Wireless Interconnection
To interconnect multiple HEIMAN smoke detectors:
- On each detector, locate the DIP switches (usually inside the battery compartment or on the back).
- Set the DIP switches on all detectors you wish to interconnect to the same ID. There are 16 possible ID groups. Only detectors with matching IDs will form a connection group.
- Once the DIP switches are set, activate each detector by installing it on its mounting bracket.
- Test the interconnection by pressing the test button on one detector. All interconnected detectors should sound the alarm.
A maximum of 40 wireless smoke detectors can be interconnected. The wireless transmission range is over 150 meters in open air.

Operating
1. Testing the Alarm
Press and hold the large central test/silence button on the detector. The alarm will sound, and the LED indicator will flash rapidly. If interconnected, all linked alarms should also sound. Release the button to stop the test. Test your smoke detector weekly.
2. Silence Function
In case of a nuisance alarm (e.g., from cooking fumes), press the test/silence button to temporarily silence the alarm for approximately 10 minutes. The alarm will automatically reset after this period if the smoke has cleared. If smoke is still present, the alarm will reactivate.
3. LED Indicator Meanings
- Green LED (flashing every 60 seconds): Normal operation.
- Red LED (flashing rapidly with alarm): Smoke detected.
- Red LED (flashing every 60 seconds with a chirp): Low battery warning.
- Red LED (flashing every 60 seconds with a different chirp): Malfunction/fault.

Maintenance
1. Cleaning
Clean your smoke detector at least once a month. Use a soft brush attachment on your vacuum cleaner to remove dust and debris from the vents. Do not use cleaning solvents or spray chemicals directly on the detector.
2. Battery Status
The detector features a 10-year sealed battery. When the battery is low, the detector will chirp approximately once every 60 seconds, accompanied by a red LED flash. Replace the entire unit when the low battery warning sounds, as the battery is not user-replaceable.
3. Regular Testing
Test your smoke detector weekly by pressing the test button. This ensures the alarm and its electronic components are functioning correctly.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Alarm chirps every 60 seconds | Low battery. | Replace the entire smoke detector unit. |
| False alarms | Cooking fumes, steam, dust, high humidity, or improper placement. | Press the silence button. Relocate the detector if false alarms persist due to environmental factors. Clean the detector. |
| Alarm does not sound during test | Battery not activated, unit malfunction, or end of life. | Ensure battery is activated. If not, replace the unit. |
| Interconnected alarms do not all sound | DIP switches not set to the same ID, or range issues. | Verify all interconnected detectors have the same DIP switch ID. Ensure detectors are within wireless range (150m open air). |
