The Vanderbilt (formerly Bewator / Siemens) V44 Duo is a programmable codelock for one or two doors. It is possible to set separate codes for each door or the same code for both. The V44 Duo also provides the option of door control and alarm output. This keypad has a code capacity of 20 four-digit codes and 10 six-digit codes. By using the V44 Duo’s tamper switch in combination with the SK5 security unit, it is possible to achieve a higher level of security.

Please note this keypad was branded "Bewator" for many years and was also branded "Siemens" for a period. The product code was changed from "K44" to "V44" and the fascia colour changed from grey to blue with the last brand change to "Vanderbilt". There is also a single door "V42" version of this keypad which is very popular.
