One of the most common questions we receive from users is around mounting the keypad in an outdoor enclosure in extreme weather to keep it safe from the elements.
Each keypad behaves differently in the enclosure. We do NOT recommend using the IRIS v3 (IL021) with an enclosure since it seems to constantly trigger the motion sensor. However in out tests the other keypads (IRIS v2, Xfinity XHK1, Xfinity Centratlite and Centralite Retail) do reasonable well with outdoor coverings. Do keep in mind that when using a covering it may interfere with the motion sensor and accuracy of the temperature sensor.
