Can I connect the IR interface 14584.1//20584.1 to the BUS line of the sound system?
No, this device must be connected to the home automation BUS line and configured in a group with the sound system menu.
What is the item 01904 used for?
Item 01904 is a shunt branch for the sound system which allows you to create an additional branch to the principal line if required.
What is the maximum number of sound devices installable in one system?
A system can manage up to 32 devices.
Does the last device on the BUS line of the sound system have to be terminated?
Yes, devices at the ends of sound system branches must be terminated via the special termination jumpers present on every device.
Which cable do I use for the BUS of the sound system?
The cable for this system is part no. 01840.B.
Can I use a 10+10 W amplifier with 3W speakers?
Yes, it is possible to combine amplifier 01901 to speakers 20587.
Can I use a 1+1W amplifier with 10W speakers?
Yes, it is possible to combine amplifier 20581 to speakers 20588.
What is the item 20580 used for?
The 20580 power supply can power the flush mounted amplifier part no. 20581 without burdening the main BUS 01801 power supply.
Can I bind 2 zones to a single amplifier?
No, every zone is managed by a single amplifier.
How many sources can I use on the same system?
The maximum number of sources permitted in the system is 4.
Can I activate the sound system in a scenario?
Yes, if an audio zone is included in a scenario, the system activates the area with the preset volume and station when the scenario is called.
What is the "Sleep" function?
The "Sleep" function, programmable on the 20581 controls, allows the system to turn off automatically after a time set by the user.
What is the "Snooze" function?
The sound system can activate particular audio zones at specific time and, as with any common alarm clock, you can press an icon which temporarily turns off (about 8min) the audio, resuming normally afterwards. This function is only available on 3 and 4+4 module Touch pad.
How many home automation devices can I connect to the BUS terminal of sound system amplifiers (20581/14581, 01901)?
The dedicated "BUS" terminal on the amplifiers can connect up to 3 By-me home automation devices .
How many home automation devices can I connect to the output of 01903?
There is a "BUS" terminal on this devices dedicated to the creation of a small home automation branch with a maximum of 10 By-me devices.
What is the maximum distance between the amplifier 14581, 20581 and the speakers 20587?
The maximum distance between the speaker and amplifier depends on the cable section used. With a 1.5 mm cable, the distance can be up to 30 m, while the maximum distance drops to 10 m for a 1 mm cable.
What is the maximum distance between the amplifier 01901 and the speakers 20588?
The maximum distance between the speaker and amplifier depends on the cable section used. With a 1.5 mm cable, the distance can be up to 30 m, while the maximum distance drops to 10 m for a 1 mm cable.
Can I connect just one speaker to amplifiers 01901, 14581, 20581?
Yes, in this case you must terminate the unused amplifier channel with a 100 Ohm 1Watt resistance.
Is the layout structure of the sound system the same as the home automation line?
No, sound devices require in-out type wiring. The SAI and home automation devices do not require a particular topological structure.
Can I avoid installing the line decoupler 01902 on a sound system?
No, the device is required to ensure the transmission of the audio data.
