We would be interested in the Contact Sensor element of the alarm system, but wouldn’t necessarily need the Motion Detectors - if we cover the downstairs entry points this feels like enough for what we would use it for, personally. Is it possible to purchase the items individually, rather than as a kit, so we don’t have the Motion Detector element of the kit just lying around? We would need the contact sensors, base station, keypad, and range extender… Are we missing anything? Thank you!
You can use as many or as few of the different detectors as you want with your alarm system. There may be an upper limit but I’m not aware of it.
So no, you don’t have to use the motion detector.
Thank you, @SolarEclipse , for confirming!
