Interlogix Ecolink TX-E251 Long Range Door/Window Sensor Qolsys, GE & Interlogix Compatible

This sensors works great. Had a different long range sensor that intermittently connected. This one has been perfect. Connection is solid.

These sensors are not as robust as the original interlogix 319.5 sensors. Very cheaply made.

Just attempting install. Instructions do not identify parts(two separate pieces and the magnet piece plus "reed switch" pins), nor does it say how or what position they should be put in(in my case for a sliding door),where to place the glue paper, where do the reed switch pieces go if you use them. No identifying pictures or examples. It says there are "2 zones"-how do you set this? Even getting to the battery says "slide the case cover off". It is solid at both ends and no way to slide off. Either way-I installed it like my others and nothing triggering. Total Bust.

Installed easily.
