The low battery threshold is set so the battery will provide no less than 30
days of operation and at that point the CO alarm will send a 'low battery'
signal. If the battery is low ,horn will 'chirp' once every 60 seconds with
yellow LED flash until battery failure. Please replace the battery asap

Installation Instructions
Locations to install your CO alarm
Since CO gas moves freely in the air, the suggested location is in or as
near as possible to sleeping areas of the home. The human body is most
vulnerable to the effects of CO gas during sleeping hours. For maximum
protection, a CO alarm should be located outside primary sleeping areas
or on each level of your home. In the figure 1 below, are suggested
locations in the home. The electronic sensor detects carbon monoxide,
measures the concentration and sounds a loud alarm before a potentially
harmful level is reached.
