Frequently asked questions
What is a curtain detector?
A detector with a narrow beam (6° horizontal) forming a vertical detection 'curtain' along a window, door or zone, without covering the whole room.Does it need an Ajax hub?
Yes. It runs on Jeweller and needs an Ajax hub. It is compatible with all Ajax hubs and range extenders.Does it ignore pets?
Yes, when mounted correctly along a window/door, the narrow beam doesn't react to pets on the floor.What is CSP?
Correlation Signal Processing — false-alarm protection: an alarm triggers only if both PIR sensors detect an identical signal. It reduces range but also false alarms.Does it work with Home Assistant, Alexa or Google?
No. Ajax is a closed ecosystem; the detector is managed from the Ajax app, not via Home Assistant, Alexa or Google.What warranty and delivery do you offer?
24-month official warranty from Evrinet SRL (official Ajax importer). Delivery across Moldova, showroom in Chișinău at str. Columna 153.
