Sensors For Double-Hung Windows
Hi,
I recently purchased a Concord Ultra system. Thankfully I haven't purchased too many sensors, because I've ran into a problem that I hadn't anticipated.
All the windows in my house are double-hung vinyl windows, and I assumed that one sensor would take care of each window (I've got 32 windows), i.e. sensor on one pane and magnet on the other pane, so if either pane was moved the cicuit would trip.
While there is enough space to install the sensor on the horizontal sash, I don't appear to have enough space to install the magnet on the other pane.
I originally planned on using NX454, but the magnet won't fit. I then thought I'd use recessed sensors instead, but the NX458 sensor is 1.75"W and the sash width is 1"W.
I assume other people have encountered this issue, so hopefully there is a sensor that will work, as I really don't want to use two sensors on each window (extra $1K right there).
Does anyone know if the micro-sensors fit a double-hung window?
Regards,
Henry

Vinyl windows are always problematic, as are double hung windows. What you may have to do, is wire a pair of the smaller conventional contacts on the moving sections of the windows, and wire them to the hardwire input on the transmitter. You will have to program the sensor to work int this manner, but it's the cheapest and most effective solution I know of. You can use any of the transmitters that have HW inputs, and simply mount the transmitter behind the curtain line, or similar location.

As far as the nx454 is this the switch you were looking at, it’s the Micro switch for GE's concord series.

The micros are a great product 5-8 year battery life with normal use and you can change your own battery. The switch has a low profile so that don't look horrid in your windows especially windows on the front of your house. The larger NX-652's has a great battery life (20 years is possible). But they are permanent batteries, you'll have to replace the whole transmitter and they look horrible from an outdoor view of the house.
