Review title: Repeated false alarms!
Product review: I've purchased several PS-434A Motion Sensors to expand my SC-1000 system, but unfortunately I found that repeated false alarms made these sensors virtually useless. Doesn't matter where you put the sensors in your house (high or low sensitivity) sooner or later you'll get a false alarm. Currently I'm keeping them inside of closets. I guess if burglars get into my house the closets are the first places where they will be looking for valuables.I also found that PS-434A Motion Sensors working as advertised only in "Delay Mode". When the sensors are in "Instant Mode" they are only able to set off audio alarm at Control Panel SC-001, but AD-433S Emergency Dialer is not dialing (!?!).Just to be sure that nothing was wrong with my Control Panel or Emergency Dialer I also tested WT-433 Window/Door Sensors. They've worked in Delay and Instant Mode without any problems.
