Every apartment building is different – from a small walk‑up with a dozen units to a high‑rise tower with hundreds of residents. A one‑size‑fits‑all intercom system rarely fits. That is why FARHD offers a flexible, scalable apartment intercom solution with multiple wiring options and capacity tiers.

Whether you are retrofitting an old building or equipping a new development, our analog intercom systems deliver the reliability, simplicity, and cost‑effectiveness that property managers and residents appreciate. And with our aluminum alloy outdoor panels e embedded installation design, you get a professional, long‑lasting entrance solution that blends seamlessly into any facade.

Let’s explore the three system configurations and why FARHD is the right partner for your next apartment project.

Three System Configurations – Choose What Fits Your Building

Our apartment intercom solutions are based on mature 2‑wire and 3‑wire analog technology – proven stable, easy to install, and highly cost‑effective.

1️⃣ 2‑Wire System (No Decoder) – Max 32 Flats

This is the simplest configuration. The outdoor station connects directly to up to 32 indoor monitors using standard two‑core cable. No additional decoder hardware is required.

• Ideale per: Small apartment buildings (up to 32 units), walk‑ups, low‑rise residential buildings.
• Vantaggi: Lowest cost, simplest wiring, fastest installation.
• Ideal for retrofits – Often reuses existing 2‑wire cabling.

2️⃣ 2‑Wire System (With Decoder) – Max 1024 Flats

When your building has more than 32 units, an external decoder is added to the system. The decoder expands the addressing capacity while still using the same 2‑wire cabling.

• Ideale per: Medium to large apartment buildings (33 to 1024 units).
• Vantaggi: Scalable, still uses simple 2‑wire cabling, decoder can be centrally located.
• Ideale per: New mid‑rise and high‑rise residential towers.

3️⃣ 3‑Wire System (No Decoder) – Max 1024 Flats

The 3‑wire system uses three dedicated wires (typically two for power and one for signal, or variations) to achieve high capacity without an external decoder. Transmission is stable and interference‑free.

• Ideale per: Large apartment buildings (up to 1024 units) where extra signal stability is desired.
• Vantaggi: No decoder required even at high capacity, very stable signal transmission.
• Ideale per: Large residential complexes, gated communities, and buildings with long cable runs.

All three configurations support embedded installation of the outdoor station, creating a flush, professional appearance that is resistant to tampering.

Aluminum Alloy Panel – Durable, Premium, Weatherproof

The outdoor station is the most visible part of any apartment intercom system. It must withstand daily use, weather extremes, and occasional vandalism. That is why FARHD uses aluminum alloy for our panels:

• Corrosion‑resistant – No rust, even in coastal or high‑humidity environments.
• Impact‑resistant – Withstands accidental bumps and intentional tampering.
• UV‑stable – Won’t fade or become brittle after years of sun exposure.
• Premium look and feel – Clean lines, matte finish, complements modern architecture.

Each aluminum alloy panel is paired with a metal rain cover (included) and rated IP65 – dust‑tight and protected against low‑pressure water jets. Operating temperature: -40°C to +70°C.

Embedded Installation – Clean, Flush, Professional

Surface‑mounted outdoor stations are common, but they can look bulky and offer more opportunities for tampering. FARHD supports embedded installation (also called flush mounting), where the outdoor station is recessed into the wall.

• Sleek appearance – Only the front panel is visible, flush with the wall surface.
• Tamper‑resistant – No exposed edges or screws on the sides.
• Space‑saving – Ideal for narrow corridors or tight entryways.
• Professional finish – Preferred by architects and property developers.

An embedded box (backbox) is required for this installation method. We provide detailed dimensions so your contractor can prepare the wall opening in advance.

Ideal for Apartment & Residential Projects

Tipo di edificio	Recommended Configuration
Small apartment (≤32 units)	2‑wire, no decoder – simplest, most cost‑effective.
Mid‑rise apartment (33‑200 units)	2‑wire with decoder – balances capacity and cost.
High‑rise tower (200‑1024 units)	2‑wire with decoder or 3‑wire – both handle high capacity reliably.
Gated community / complex	3‑wire – excellent signal stability over longer distances.
Renovation / retrofit	2‑wire (no decoder) – often reuses existing cabling, minimal disruption.

All configurations work with FARHD’s range of indoor monitors (audio handsets, video monitors, or hands‑free units). We also offer RFID card readers, keypads, e face recognition options for enhanced security.
