Complete SecurityHow would you like a security system that provides complete security via a host of devices, including keypads, sirens, detectors and wireless keys, and also supports GSM and IP communications - all of it wirelessly? DSC's 2-Way Wireless Security Suite delivers just that…and so much more.The Key to Better SecurityThe key to a better security system is the WT4989 2-Way Wireless Key from DSC. Designed to work with the Alexor Wireless Panel, the WT4989 offers great added value to any security system installation.Safe and SoundThe WT4989 provides users with management of their Alexor Wireless Panel and the added confidence of portable personal protection - directly at their fingertips. Users can arm/disarm the system easily as they approach their house or call for help from anywhere inside or in close proximity to it (via the panic button). Because the WT4989 employs 2-Way wireless, Alexor communicates to the key and vice-versa. Featuring an icon display and built-in buzzer, the WT4989 provides both visual and audible indication to the homeowner that the operation they requested has been performed and acknowledged. System status indicators on the key alert the homeowner if the residence is in alarm or if it has recently been in alarm, before they enter the home.Wireless Convenience & Remote ManagementThe WT4989 has five buttons, the system status button, plus four additional programmable buttons with six available function options. Programming for certain functions can include garage door openers, indoor/outdoor light operation or powered gate access. A multifunction clip allows the wireless key to be clipped to an easily accessible location like a belt, keychain or lanyard.
