The T-7702A is a professional-grade desktop IP paging and intercom station designed for the ITC T-7700 Series network audio system. It combines a large 7-inch color touch screen with physical programmable buttons, offering both flexibility and instant access for operators in security, administration, and broadcast control roles.
Intuitive Touch Interface: The 65K color resistive touch screen displays zone maps, terminal status, and call history. The interface is customizable via T-7700RP software, allowing administrators to tailor the layout for specific workflows – ideal for reception desks, security posts, and control rooms.
Superior Audio Quality: Full-duplex communication with integrated acoustic echo cancellation enables natural, hands-free conversations without clipping or feedback. The built-in 2W speaker provides clear monitoring, while the headphone output supports private listening in noisy environments.
Physical Reliability: Ten rugged mechanical buttons provide tactile feedback for one-touch paging to emergency zones, all-call broadcasts, or preset groups. Buttons are backlit and can be labeled with custom inserts. Each button is independently programmable for zone, message, or action.
65K color display, 800x480 resolution. Resistive technology works with gloves or stylus. Customizable GUI via server software.
Simultaneous two-way voice communication. Acoustic echo cancellation up to 60dB. Wideband audio (50Hz-7kHz).
Physical buttons with dual-color backlight. Assignable to zones, groups, all-call, or preset voice messages. Key caps removable for custom labeling.
The T-7702A can be configured to monitor ambient audio via its built-in microphone. This allows security personnel to listen to remote areas (with compatible IP speakers/intercoms) for situational awareness before responding.
| Action Type | Description | Example Use |
|---|---|---|
| Zone Paging | Immediate broadcast to single or multiple zones | Emergency evacuation, department paging |
| All-Call | Broadcast to every speaker in the system | Fire drill, general announcement |
| Intercom | Direct call to specific intercom station | Call security, maintenance request |
| Preset Message | Play pre-recorded audio file | Lunch menu, store closing |
| Relay Control | Trigger short-circuit output | Open gate, activate beacon |
• AEC: 60dB echo cancellation, 32ms tail length • NR: -15dB noise reduction • AGC: ±12dB automatic gain control • EQ: 5-band parametric equalizer per profile. All processing is onboard, no server load.
Short-circuit input (2x): Connect to third-party sensors (PIR, door contact). When triggered, can initiate pre-defined actions (e.g., play message, call security). Short-circuit output (1x): Relay output (30V/1A max) for external light, siren, or door strike control.
| Model | Display | Programmable Keys | Audio Features | I/O | Best For |
|---|---|---|---|---|---|
| T-7702A | 7" Resistive (65K) | 10 | Full-Duplex, AEC, 2W speaker | 2x In, 1x Out | General paging, intercom |
| T-7702M | 7" Capacitive (1024x600) | 12+6 | 8x AUX, 10x LINE, FM/SD/USB | Extended I/O | Broadcast studio, advanced |
| T-7700A/AN | 7" Screen | None (touch only) | Full-Duplex, 2W speaker | Basic | Simple intercom |
The T-7702A is fully PoE powered (IEEE 802.3af Class 3). No separate power adapter required if connected to a PoE switch. For non-PoE networks, a 12V/1A DC adapter is included. Ensure network cable distance ≤100m for reliable operation.
All T-7702A settings (button mapping, touch layout, audio parameters) are centrally managed via T-7700RP software. No local configuration required – ideal for multi-site deployments with standardized paging workflows.
