There is one key difference between these two wireless door/window contacts: the 5811 protects a single window/door within its wireless zone, and the 5816's internal screw terminals can be utilized to
hard wire an additional zone to any wired door/window contact.
Aesthetically, these two products differ slightly. The 5811 is the newer, slimmer model, measuring 2.25 inches high x 1.25 inches wide x 3/8 inch deep, while the 5816 has a boxier shape, measuring 3 inches high x 1.5 inches wide x 1.25 inches deep. There's also a small difference in signal range between these two transmitters. The 5811 has a range of 150 nominal feet from the closest RF receiver, and the 5816 has a range of 200 nominal feet.
Keeping in line with the sizes of the products, the 5816 requires a larger, cylindrical CR123A 3V battery, which should last 3-5 years. The slim 5811 uses a smaller, disc-shaped CR2032 3V battery, which lasts an average of 4 years.
