Review: Reliable dual purpose transmitter - Versatile Dual use transmitter
Review: Reliable Door/Window Transmitter for Honeywell Lynx - I now have one of these on every external door of my house, as well as a few other internal doors (like the basement door) and a few windows. ** In the Box ** They're really easy to install, and they come in a box with a plastic mounting plate, a magnet and magnet spacer, the proper screws for mounting everything, some double-sided tape (which is okay for indoor use, but I'd rather use the screws!), and an A123 battery (see my picture above for an overview of all the included bits). ** Quality and Installation ** The design is pretty minimal, and fits in okay with the white door and window trim in my house. Honeywell also makes a 'slimline' version of this sensor that's much narrower--but also much more expensive! The sensor is easy to maintain--every couple of years (when a battery dies), just push in the tab on the bottom with your fingernail and pop off the front cover (your alarm system will start beeping at this point, since you're 'tampering' with the transmitter... ignore it and reset it when you're done). Pop out the old battery, put in a new one, then replace the cover. Nothing to it. ** Function and Battery Life ** These sensors use two Loops for sensing door/window open and close states: Loop 2 (most common) is used with a magnetic reed switch (magnet must be within an inch or so of the reed switch sensor), and Loop 4 lets you use a wired contact (installation is more difficult, and probably uncommon). As long as you have a flat surface on the door and on your door casing or wall within an inch or so of each other, you can just mount the magnet to the door, and the transmitter to the wall/door trim, and you're done! I installed my Honeywell L5100PK - LYNX Touch security system a few months ago, and haven't yet had a battery die. A few other people I know have a similar Lynx system, and nobody seems to have any complaints about battery life. ** Recommendation ** Buy enough of these to cover every entry/exit in your house, and you're set! Get the slimline version if you can afford it--otherwise, these things work great and are very reliable.
