Hi Matt,

<div><span style="font-family: Arial, Helvetica, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', NotoColorEmoji, 'Segoe UI Symbol', 'Android Emoji', EmojiSymbols; font-size: 16px;">At SNF w</span>e have occupancy sensors in our litho areas, satellite labs,
and offices. <span style="font-family: Arial, Helvetica, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', NotoColorEmoji, 'Segoe UI Symbol', 'Android Emoji', EmojiSymbols; font-size: 16px;">We don't get false triggers of lights </span><span style="font-family: Arial, Helvetica, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', NotoColorEmoji, 'Segoe UI Symbol', 'Android Emoji', EmojiSymbols; font-size: 16px;">due
to vibration or noise, just </span>occasional annoyances. Yesterday I overheard a student giving an outside tour of our lab trying to describe the tools in the dark <span style="font-family: Arial, Helvetica, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', NotoColorEmoji, 'Segoe UI Symbol', 'Android Emoji', EmojiSymbols; font-size: 16px;">to
his visitors</span>. Noah's suggestion of a bypass option during business hours is a good one. A few of our lamps are<span style="font-size: 12pt;"> <span style="font-family: Arial, Helvetica, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', NotoColorEmoji, 'Segoe UI Symbol', 'Android Emoji', EmojiSymbols; font-size: 16px;">always
on and tied into <span style="font-family: Arial, Helvetica, sans-serif, 'Apple Color Emoji', 'Segoe UI Emoji', NotoColorEmoji, 'Segoe UI Symbol', 'Android Emoji', EmojiSymbols; font-size: 16px;">emergency</span></span> backup power.</span></div>

Hi All,</p>

Our university is in the process of constructing a new 8500 sqft cleanroom. It has been proposed that 30min occupancy sensors are to be used in the cleanroom bays and chases (one at each end of each bay and chase). Personally, I have a lot of reservations
about using such sensors given safety concerns created by potential blind spots, especially when staff are working in tight spots around various processing tools. In addition, I have concerns about sensitivity given the noise and vibration in many areas of
the lab. Does anyone have experience (good or bad) with such sensors in a cleanroom environment?</p>
