FAQ
TL;DR: Example: apartment 15 uses 4 jumpers (1+2+4+8), and "The sum of the weight of the jumpers should be the same as the apartment number." Wire L- / L+, set 'Other' jumpers, and try ZW6 both ways. For residents wiring a Cyfral CC‑2000 to Laskomex CD‑2500 or checking compatibility. [Elektroda, zybex, post #17302541]
Why it matters: You’ll avoid silent calls, error codes, and doors that won’t unlock after ringing.
Quick Facts
- Binary addressing: fit jumpers whose values add to your flat number (e.g., 15 = 1+2+4+8). [Elektroda, zybex, post #17302541]
- On non‑Cyfral systems (e.g., Laskomex CD‑2500), set the profile to “Other” and configure ZW2, ZW5, ZW6; ZW6 may need trial. [Elektroda, zybex, post #17302828]
- Polarity-sensitive two‑wire bus: verify L+ and L‑ with a voltmeter; reversed lines can cause silence. [Elektroda, zybex, post #17338519]
- Genway panels require Genway handsets (e.g., WL‑02NLFD); Cyfral CC‑2000 is incompatible. [Elektroda, Ircys, post #17338904]
- Analog multi‑core systems (e.g., Fermax 101CI15C) cannot use the digital CC‑2000. [Elektroda, zybex, post #17746689]
Which terminals do I connect when replacing with a Cyfral smart-d CC‑2000?
Use the same two bus conductors. Connect L‑ to the wire that was on L‑ (e.g., brown) and L+ to the wire that was on L+ (e.g., green) in your old unit. The CC‑2000 uses only L‑ and L+ on a two‑wire bus. Leave any extra conductors isolated and secured. [Elektroda, zegnallo, post #17302420]
How do I set my apartment number on the CC‑2000?
Fit jumpers whose numeric weights add to your flat number. For apartment 1, fit only “1.” For apartment 15, fit 1+2+4+8. "The sum of the weight of the jumpers should be the same as the apartment number." How‑To: 1. Locate pins 1, 2, 4, 8, … 2. Add values to reach your number. 3. Place jumpers on those values, then test. [Elektroda, zybex, post #17302541]
Which system jumpers (ZW…) should I use with a Laskomex CD‑2500?
Set the CC‑2000 for “Other” (non‑Cyfral) per the on‑board table. Configure ZW2, ZW5, and ZW6 to the right‑hand column. ZW6 is marked “or,” so try both positions and keep the one that gives proper audio and control. This aligns signaling with the Laskomex bus. [Elektroda, zybex, post #17302828]
The panel rings but the door won’t open — how do I fix it?
Assign the correct address using the jumper sum, then set the remaining configuration jumpers for “Other.” A missing address or wrong profile can allow ringing while blocking call control and door release. After setting the address and system options, retest ringing, talkback, and unlock. [Elektroda, zybex, post #17302541]
I see “ER‑2” on the panel during setup — what does it imply?
That error appeared when the handset lacked the correct address jumper. In the reported case, it rang without the jumper but would not open the door. Add the proper apartment jumper and system settings, then test again. [Elektroda, zegnallo, post #17302530]
How do I verify polarity and what happens if L+ / L‑ are reversed?
Measure the two bus wires with a voltmeter to identify plus and minus. If you reverse L+ and L‑ at the CC‑2000, you may get complete silence even though the panel signals. Correct the polarity and, if audio still fails, try the alternate ZW6 position. [Elektroda, zybex, post #17338519]
Do I need to adjust the “Balans – other” control?
Yes. Use the “Balans – other” potentiometer to set microphone sensitivity and avoid feedback. Start mid‑range, then fine‑tune while speaking from both ends until speech is clear without echo. This trimmer helps the handset match third‑party systems. [Elektroda, zybex, post #17303307]
Will a Cyfral CC‑2000 work on Genway installations?
No. Genway and Cyfral use different signaling, so the CC‑2000 will not work on Genway buses. Use a compatible Genway uniphone, such as the WL‑02NLFD, to restore full functionality. [Elektroda, Ircys, post #17338904]
Can a digital CC‑2000 replace an analog Fermax 101CI15C handset?
No. The Fermax 101CI15C is an analog multi‑core handset, while the CC‑2000 is a digital two‑wire device. They are not interchangeable. Choose an analog replacement matched to the Fermax system’s wiring and signaling. [Elektroda, zybex, post #17746689]
My old board shows pins 2–128 with no jumpers — is that normal?
Yes. Address headers often list many pins, like 2 through 128, but you install only what your address needs. For apartment 1, only the “1” pin is jumpered; the rest remain empty. The same photo also shows the “Balans – other” trimmer. [Elektroda, zybex, post #17303307]
I’m in apartment 1 — do I use only one jumper?
Yes. Install just the “1” jumper for flat 1. Leave 2, 4, 8, and higher values open. Then configure the remaining ZW jumpers for “Other,” because Laskomex is not a native Cyfral controller. [Elektroda, zybex, post #17302541]
Does a keypad on the entrance panel mean I need a digital handset?
No. A numeric keypad does not prove the system is digital. Some analog systems also use keypads. Confirm system type before buying, or you risk total incompatibility and a non‑working handset. [Elektroda, karl102, post #17338607]
