1 normally open contact not potential-free 10A/250V AC, 230V LED lamps up to 400W, incandescent lamps 2000 watts. Delayed release with switch-off warning and permanent light button can be switched on. Encrypted radio, bidirectional radio and repeater function can be switched on. Standby loss only 0.8 watts. For built-in installation. 45mm long, 45mm wide, 33mm deep. Supply, switching and control voltage locally 230V. Contact switching at zero crossing to protect the contacts and consumers. This radio actuator as a staircase light delay switch has the most modern hybrid technology developed by us: We have combined the wear-free reception and evaluation electronics with a bistable relay that switches at zero crossing. This means that even when switched on, there is no coil power loss and no heating as a result. After installation, wait for the short automatic synchronization before connecting the switched consumer to the mains. In addition to the radio control input via an internal antenna, this staircase light delay switch can also be controlled locally with a conventional 230V control button that may be mounted in front of it. Glow lamp current up to 5mA, depending on the ignition voltage of the glow lamps. After a power failure, the lighting is switched on again if the time period has not yet ended. Encrypted sensors can be taught in. Bidirectional radio and/or a repeater function can be switched on. Every change in status and incoming central control telegrams are confirmed with a radio telegram. This radio telegram can be taught in other actuators, Professional Smart Home controllers and universal displays. With the upper rotary switch in the LRN position, up to 35 radio buttons and/or motion brightness sensors FBH can be assigned, one or more of which are central control buttons. The desired function of this stairway light after-run switch is then selected. The flashing of the LED as soon as a new setting range is reached when the rotary switch is turned is a good way to find the desired position. NLZ = after-run switch. TLZ = stairway light timer. +Pushbutton permanent light = TLZ with pushbutton permanent light. +Switch-off early warning = TLZ with switch-off early warning. +Pushbutton permanent light and switch-off early warning = TLZ with pushbutton permanent light and switch-off early warning. If the pushbutton permanent light is switched on, you can press the button for longer than 1 second to set the light to permanent, which switches off automatically after 60 minutes, or you can switch it off by pressing the button for longer than 2 seconds. If the switch-off early warning is switched on, the lighting flickers starting around 30 seconds before the time expires and a total of 3 times at increasingly shorter intervals. If the switch-off early warning and pushbutton permanent light are switched on, the switch-off early warning only occurs after the permanent light is switched off.The release delay is set from 1 to 20 minutes using the lower rotary switch. If motion-brightness sensors FBH are taught in, the switching threshold at which the lighting switches on or off when there is movement, depending on the brightness, is set for the last FBH taught in. The release delay that can be set on the FTN61NP is extended by the time of 1 minute set in the FBH. The LED accompanies the teaching process in accordance with the operating instructions and indicates radio control commands during operation by flashing briefly.
