SKU AJ-42823
- Fast shipping from four branches
- 30-day returns on unopened products
A wireless PIR covering 39 feet across 88.5 degrees, with pet immunity up to 44 pounds. It is the volume motion detector on an Ajax job, and it runs up to five years on the battery it ships with.
Built for the installer
Pet immunity here is a real specification rather than a marketing line: up to 44 pounds in weight and up to 1.6 feet in height. Above that the animal is treated as a person, which is the honest way to quote it to a customer with a large dog.
SmartDetect is the software filter that separates a person from a heat source. Combined with temperature compensation it holds detection performance from 14F to 104F, which matters in a space where the ambient temperature approaches body temperature and a cheaper PIR starts missing people.
Key features
- Pet immunity to 44 lb and 1.6 ft, a specified limit rather than a vague claim
- SmartDetect filtering separates a person from a passing heat source
- Temperature compensation holds detection from 14F to 104F where cheap PIRs lose sensitivity
- Up to 5 years battery life on the pre-installed CR123A
- Three sensitivity levels set remotely, with no trimmer to adjust on a ladder
