9940En and 9941En keypads are designed to work with 9853, 9851, 9752, 9751 and
9651 alarm system control units. These keypads are a direct replacement
for the 9930, and offers the advantage of smaller size and improved
appearance. The 9940 keypad has a proximity tag reader coil fitted inside
the case and can work with the same proximity tags as the 934 proximity reader
module. The 9941En has no detector coil fitted.
