The compact and sleek DSC WT5500 wireless Keypad is designed to work with the DSC Alexor Wireless Panel. Since Alexor is mounted in a secure location away from main access areas, the DSC WT5500 provides an easy-to-use and convenient main interface to the system. With handy wall or free-standing desk stand mounting options and the ability to connect up to four keypads per system, you have more choices in where keypads may be located throughout the business or home. The DSC WT5500 can be conveniently located on the wall just inside the front door or on a deskstand in the kitchen or even near a bedside Break Free from Wires & Lengthy Installs The WT5500 is entirely wire-free. With batteries as its main power source, it does not require any drilling or electrical wiring for its installation and operation. With the wall mount option, it simply affixes the wall plate (included) onto the wall and sits the keypad on the plate. Keypad programming is simple and fast with DSC’s Quick Enroll feature. The keypad also provides installer programming, so no dedicated keypad is needed for installation.
