Is anyone able to give an age on this pir please? Im trying to put an age on a loft conversion and have nothing to go off, but it does have this pir fitted, so may help me to put a rough age on it.

Many thanks

Google says: Aritech DR series passive infrared (PIR) sensor, most likely the Aritech DR115 or DR110, which was widely manufactured and installed during the mid-to-late 1980s.
