Product Description
Visonic SPY-4 PIR Motion Detector Plaster Ground. Visonic's plaster ring yeilded a messy install after plaster. I deisgned this for a cleaner finish install. It is set up for 3/4" plaster/drywall but can be shimmed or trimmed for different finish thickness. Sensor fits snugly into plaster ground, sensor can be removed easily for service without damage to the plaster.
