Questions and answers
When I try to install the alarm on the mounting bracket, it won't stop alarming
The Siterwell GS811-A alarm may keep alarming during installation because it is designed to detect carbon monoxide and alert users when dangerous levels are present. However, if it alarms continuously when mounting, possible reasons include:
1. Test Mode Activation – Pressing the TEST/RESET button as part of the installation process may trigger the alarm.
2. Improper Installation – If the unit is not securely hooked onto the screws, it may not function correctly.
3. Environmental Factors – Nearby sources of combustion or poor ventilation may cause the alarm to detect carbon monoxide.
4. Battery Issues – If the battery is low or incorrectly installed, the unit may sound a warning.
5. Faulty Unit – If the alarm continues to sound despite correct installation and a safe environment, it may be defective.
To resolve the issue, ensure proper installation, check the battery, and press the TEST/RESET button. If the alarm persists, consider contacting the manufacturer or a qualified technician.

As soon as I install the smoke and CO detector onto the mount, it starts to beep

If the alarm continues to sound, it may indicate a problem, and the user is advised to contact the manufacturer or agent.
