FAQs

Does this detector sense smoke?

No, the AJ-833SI is specifically designed for carbon monoxide detection. For smoke protection, consider the SAFE-TECH Home Interlinked Smoke Heat Alarms.

Can I replace the battery after 10 years?

The 3V lithium battery is designed for a 10-year lifespan to match the sensor life. Once the unit expires, it must be replaced for your safety.

How many alarms can I link together?

The system supports multiple units within the SAFE-TECH AJ series; please refer to the specific pairing guide included with your device for the maximum limit.

What should I do if the alarm sounds?

Immediately move to fresh air, open windows and doors to ventilate the area, and contact emergency services or a qualified gas engineer.

Where is the best place to install this?

Install it in rooms with fuel-burning appliances and at least one unit on every floor and in or near sleeping areas.

Troubleshooting

Device displays a fault code

Clean the exterior to ensure sensors are not blocked and restart the system according to the manual. If the fault persists, contact support as the sensor may have reached the end of its life.

Alarm triggers when no CO is present

Ensure the detector is not located too close to cooking fumes or moisture, and move it away from chemical cleaners or aerosol sprays.

  • 10-year maintenance-free battery life
  • Interconnects with other AJ series alarms
  • Real-time concentration display via LCD screen
  • Easy mounting hardware included

Setup, Compatibility & Care

Installation is straightforward using the included wall-mount hardware. Position the detector in areas where gas accumulation is likely, such as near gas boilers, heaters, or in sleeping quarters, keeping it at least 1-3 meters away from appliances to prevent false readings. To maintain the device, periodically test the alarm by pressing the test button. Use a soft, dry cloth to clean the exterior of the unit, and avoid using aerosol sprays or solvents near the sensor, as these can permanently damage the electrochemical membrane. The device is compatible exclusively with other SAFE-TECH AJ series interlinked alarms.
