The PS15EMZ5-1 Plug-in Appliance Module is designed to provide Z-Wave control to a connected load. The PS15EMZ5-1 module is plugged into any standard grounded AC wall outlet, and the appliance or other device is then plugged into the module. Once connected, the appliance/device can be turned on or off remotely via the Z-Wave controller. The module contains two power receptacles - one controlled, and one pass-through (powered at all times).This plug-in Appliance Module 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).
