Desktop IP Intercom & Paging Station (Regional Variant)
7" Screen • Full-Duplex Intercom • 2W Speaker • Short-circuit I/O • Custom Ring Tones
T-7700AN
Functionally identical to T-7700A. The T-7700AN is a regional variant of the popular T-7700A desktop IP intercom station. It features the same 7-inch display, full-duplex audio with echo cancellation, built-in 2W speaker, and short-circuit I/O. The 'N' designation indicates a different firmware region for ring tone storage and default UI language. Fully compatible and interchangeable with T-7700A in mixed deployments.

Hardware: Identical. Same PCB, same components, same I/O.
Firmware: The AN variant has a different memory map for ring tone storage and defaults to a different UI language region (e.g., English UK vs English US, or localized for specific export markets).
Interchangeability: Fully compatible. T-7700A and T-7700AN can be mixed in the same system and managed identically via T-7700RP software. Server pushes configuration regardless of variant.
The T-7700AN is a regional variant of the T-7700A desktop IP intercom station, developed for international markets requiring specific firmware localization. It provides the same reliable, cost-effective two-way communication as the T-7700A, with identical hardware specifications and performance characteristics.
Clear Audio, Simple Operation: Full-duplex audio with acoustic echo cancellation ensures natural, interruption-free conversations. The built-in 2W speaker provides ample volume for office environments, while the 3.5mm headphone jack allows for private listening. The 7-inch color display shows caller ID, call history, and directory with large, easy-to-press buttons.
Flexible I/O for Automation: A short-circuit input can trigger a call to a preset destination (e.g., security) when a door sensor is activated. The short-circuit output can control an external strobe light or door strike, enabling basic access control or visual alerting directly from the intercom.
Simultaneous talk/listen with advanced echo cancellation. Wideband audio (100Hz-7kHz) for exceptional voice clarity.
1 input, 1 output. Trigger calls from sensors, or activate relays/lights upon call arrival. 5V TTL levels, configurable.
Upload custom WAV files via server. Differentiate call types (internal, emergency, door) by distinct ring tones.
| Port | Type | Voltage/Current | Configurable Actions |
|---|---|---|---|
| Input | Dry contact (optically isolated) | 3.3V DC, 5mA |
• Call specific extension • Trigger all-call paging • Play preset message • Send email alert (via server) |
| Output | Open collector | 30V DC, 100mA max |
• Activate on incoming call • Activate during paging • Toggle on/off via touch • Pulse for door strike |
The T-7700AN is configured at the factory with:
Important: All regional settings can be overridden via T-7700RP server software. The AN variant is not locked to any specific region and can be reconfigured for global use.
| Model | Display | Programmable Keys | Audio I/O | Special Features | Best For |
|---|---|---|---|---|---|
| T-7700A | 7" TFT | 0 (touch only) | 2W spk, MIC in, HP out | Short-circuit I/O | Standard desktop intercom |
| T-7700AN | 7" TFT | 0 (touch only) | 2W spk, MIC in, HP out | Regional variant, same I/O | International deployments |
| T-7702A | 7" Resistive | 10 | 2W spk, MIC in, HP out | 10 programmable keys | General paging & intercom |
| T-7702M | 7" Capacitive HD | 12+6 | 8x AUX, 10x LINE, XLR | FM/SD/USB, 1km remote | Broadcast, complex mixing |
The T-7700AN desktop intercom is distinct from the T-7700A high-performance IP controller (server hardware). These are entirely different product categories sharing similar model numbers. The desktop intercom is for end-user communication; the controller is the central server. Always verify the product category when ordering.
T-7700A and T-7700AN are 100% interchangeable in the same system. They use identical firmware binaries; only the factory default settings differ. Once provisioned by the T-7700RP server, both models operate identically. No special configuration is required for mixed fleets.
When ordering, specify T-7700AN for:
For all other regions, T-7700A is the standard model. Both are available globally.
