Minimal Installation and Maintenance

Honeywell X- Series CO alarms are extremely easy to install and do not need any external power to operate. These CO alarms can simply be fixed to any wall or ceiling by using screws to fix the mounting plate into position before sliding the alarm into position, automatically activating the detector. For even easier installation, the detector can be installed onto the mounting plate to activate it, and hung onto the wall using the nail provided or placed freestanding on a shelf.

X-Series CO alarms include batteries that last for the life of the detector. They do not need to be replaced, once the alarm has reached the end of its life the entire unit must be replaced. The only maintenance required is light cleaning to ensure the detector is free from dust and other obstructions.
