What Does a Carbon Monoxide Detector Do and How Does it ...

· The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher levels (over 150 ppm) can trigger an alarm within minutes. 3. Act quickly when an alarm sounds because low doses over long periods can be just as dangerous as …

All About Occupancy and Vacancy Sensors

· Manual-ON sensors (also called vacancy sensors) require the occupant to turn the lights ON using a manual switch, which may be integral to the sensor (shown here is an example). Partial-ON sensors activate the lights to a designated level such as 50%, and the occupant then uses a switch to bring the lights to full output. Full-ON sensors activate the lights at full output.

Light Guide: Occupancy and Vacancy Sensors

Sensors should be located so that they have the least possibility of nuisance switching and activate the lights as soon as a person enters the space. This typically involves sensor placement above or close to the main areas of activity in the space. Another aspect of location is orientation. For example, the receiving side of US sensors should be positioned toward the area of greatest traffic ...
