The ESR.1 On/Off mains-voltage receiver has a switching capacity of up to 1KW and operates a variety of devices, ie. electric motors, gates and doors, garden lighting, water features and more. This versatile receiver switches electrical circuits using volt free contacts. There are three selectable operational modes to choose from, Single switch, Two Way switch and MIMIC. MIMIC mode is a momentary contact change and is generally used with Easyswitch Key Fobs (ESF.1/ESF.4) This mode provides momentary contact closure for the duration that the key fob button is held, making it ideal for electric door and gate control. Wireless signal strength indication assists with installation. One receiver can learn up to 16 transmitters and will retain the learn codes even if the power is removed. The wireless transmission range of the receiver is 200 metres.
