The WS15Z5-1 Wall Mount Switch allows remote ON/OFF control of loads connected to the switch, and is easily wired in place of a standard wall switch.The Switch integrates with other Nortek Security and Control Z-Wave enabled products, and can also act as a wireless repeater to ensure that commands intended for another device in the network are received (useful when a device would otherwise be out of radio range).The WS15Z5-1 Wall Mount Switch has a field replaceable trim ring - the color of the device can be altered with the Trim Ring Kit model in black, brown, almond and ivory.Note to Installers: When installing a Z-Wave 3-Way Light setup utilizing Nortek Security and Control products, you will need a Load Bearing switch (WS15Z-1, WD500Z-1 or WD1000Z-1) and a non-load bearing WT00Z-1. Multiple WT00Z-1 switches can be utilized to control multiple Load Bearing devices. Please refer to the linked Technical Bulletin on Z-Wave 3-Way Light Switch Setup for more information.
