Impulse switch relay with 2 channels, 1 NO potential-free 16A/250V AC, 230V LED lamps up to 400W, light bulbs 2000W. With light scene control via PC or with radio buttons. Encrypted radio, bi-directional radio and repeater function can be connected. Standby loss of only 0.8 watt. Installed in the 230 V mains connection cable, e.g. in intermediate ceilings and lamps. 166mm long, 46mm wide and 31mm high. With cable strain relief. The switching status is maintained with supply voltage failure. A defined cut-off is performed when the supply voltage is restored. The channels can be taught in independently as ES and/or ER channels. Scene control: With one of the four control signals of a button with dual rocker programmed as scene button several channels of one or more FSR71-2x can be switched on or off at one scene. Central commands on the PC are sent using the GFVS building radio visualization and control software. To do this, program one or more FSR71-2x on the PC. The buttons are taught in with the rotary switches and, if necessary, the 2 channels can be tested. For normal operation, the middle and lower rotary switches are then set to AUTO. With the upper rotary switch the EW time (0-120 seconds) for the relay and the RV time (0-120 minutes) for surge current switch are set for all channels. If wireless motion brightness sensors FBH (Master) and / or FBH (slave) are programmed, the upper rotary switch is used to separate each channel for which the switching threshold for the light switches on and off. Settings of the upper rotary switch in accordance with the operating instructions. If wireless brightness sensors are taught in, the upper rotary switch is used to separate the switching threshold for each channel, and it is used to determine whether the light switches on or off depending on the brightness (from approx. 0lux in position 0 to approx. 50lux in position 120). A hysteresis of approx. 300lux between the on and off is fixed. An additional set RV-time is not taken into account. Only one FBH or FAH can be taught in for each channel. However, an FBH or FAH can be taught in several channels. If the FTK radio-window door contacts or the FFFG7B-RW window handle sensor are taught, the middle rotary switch can be used to set different functions in THE AUTO 1 to AUTO 4 positions and a maximum of 116 FTK can be linked. The LED under the upper rotary switch accompanies the programming process according to operating instructions and indicates control commands during operation by a short blinking.This text is machine translated.
