About this deal
N.B.2 if you want to carry on using your alarm system, you’ll have to ‘OMIT’ the zone that you’ve just removed, otherwise the alarm won’t set / work (see notes below on how to get your system working again). PIR sensor switches are particularly useful in situations where you need hands free lighting automation, such as entering a room with your hands full or needing hands free automation for hygiene purposes, such as public toilets, corridors or other buildings where light is only needed as and when required.
N.B.1 when you disconnect the wires from the sensor if you have a tamper zone wired in, then this will set the alarm off. Simply enter your code to stop the alarm. At this point a ‘tamper warning’ will appear on your alarm.
If you’re decorating your house or doing some home renovations and need to move a PIR alarm sensor, then the good news is that it’s relatively straight-forward to do. I reached out to manufacturer Maximus/Jiawei for a replacement PIR lens. They are sending me one free of charge as a one-time replacement. I have selected the answer that identified the part for me as that was the major part of my original question.
A motion sensor is triggered based on a percentage of pixel change within its field of view. This percentage can vary depending on the sensitivity of the sensor. A motion sensor is similar to a PIR sensor because it will trigger an action when objects enter its field of view, but it uses size as a measure instead of infrared energy. What is the Difference between a PIR Sensor and a Dusk To Dawn Sensor? It appears Allen & Roth is a "house brand" of Lowes, meaning Lowes buyers visit Shenzhen and go around to Chinese makers and wheel and deal to get things like this made as a limited run. However in their defense, they make the manufacturer build to US safety standards and secure a UL listing ETL listing for the item. Because US retailers are required to do that. I am not asking where I can buy this part (and I am reaching out to the manufacturer now that I have the part name); I just want to know whether it is possible (and worth my time) to replace this part or the whole item.PIR stands for Passive Infrared. We commonly use the term PIR in the context of a PIR sensor, which detects movement to initiate an electronic device. When do we use PIR? Lux - fixed or adjustable level of environmental brightness to differentiate between night and day. To remove or replace a PIR alarm sensor, first you need to remove sensor lid (normally requiring unscrewing a single screw) and plastic lens cover inside (if present). N.B. this will set the alarm off. To silence alarm, enter 4 digit code (a tamper message should appear).
