Comelit Group Germany 8461V/BM Quadra 1-4 WE Mini HF with T-coil SB2 video intercom set

Single-family house kit Quadra with mini handsfree (HF) including induction loop, SB2 video kit. This kit is delivered completely pre-addressed to address 1 and only needs to be installed and connected electrically. It is also possible to split or quarter the doorbell button using a DIP switch code and to convert this kit into a two-family house or four-family house kit by adding additional audio or video indoor stations. A maximum of 4 audio or video indoor stations can be installed per participant. The intercom is equipped with a ring line for hearing aid wearers, which transmits the audio directly to a suitable hearing aid and makes it easier for the resident to communicate with the visitor at the door. During operation, this ring line emits an alternating magnetic field, which uses electromagnetic induction to generate an electrical voltage in the hearing aid's receiving coil, the course of which is the same as that of the audio signal. In the hearing aid, this is amplified by the audio amplifier and passed to the wearer's ear via the earpiece. In order to use such induction loop systems, the hearing aid must have a so-called telephone coil (short: ""T-coil""), which absorbs the alternating magnetic field of the induction loop. The hearing aid's microphone is usually deactivated when the telephone coil is used. This kit consists of: 1x Quadra door station Art. 4893, 1x power supply Art. 1209, 1x mini hands-free indoor station with induction loop Art. 6721W/BM, branch terminal Art. 1214/2C and terminating resistor Art. 1216.
