The T-7707D features a 100V constant voltage backup input. In the event of network failure, power outage, or server issues, the speaker automatically switches to the analog backup source within 0.5 seconds. This ensures that emergency announcements, fire alarms, and critical pages are never missed.
The T-7707D is a wall-mounted IP active speaker designed for life-safety and mission-critical applications. It combines the convenience of network audio with the fail-safe reliability of a 100V analog backup input, ensuring emergency announcements are always heard.
Why 100V Backup? In hospitals, schools, government buildings, and industrial facilities, emergency announcements must be heard regardless of network status. The T-7707D connects to both your IP network and a conventional 100V paging amplifier. Under normal conditions, audio streams over IP. If the network fails, the speaker instantly and automatically switches to the 100V backup input – no manual intervention required.
Dual Audio Paths:
Same Great Audio Quality: The 2x15W digital amplifier delivers clean, intelligible audio for both primary and backup sources. The AUX input allows connection of local media players or TVs.
Easy Installation: Powered by PoE (802.3af) – a single Ethernet cable provides data and power. The 100V backup connection uses simple screw terminals.
Automatic failover to analog paging during network failure. Critical for life-safety applications.
Clean, efficient amplification for clear speech and music. Perfect for classrooms, offices, and public areas.
Connect local audio sources: media players, TVs, or conference systems.
Single Ethernet cable for data and power. No electrician required for installation.
| Condition | Audio Source | LED Indicator |
|---|---|---|
| Normal operation | Network streaming (IP) | Off (power LED only) |
| Network failure / no signal | Automatic switch to 100V backup input | Amber (backup active) |
| Network restored | Automatic return to network | Off |

T-7707D is functionally identical to T-7707AB. The "D" designation indicates a different firmware region or minor variant. Both models offer the same 100V backup feature.
The T-7707D and T-7707AB are functionally identical – both offer 2x15W amplification, AUX input, and 100V analog backup. The different model numbers indicate regional variants or minor firmware differences. For all practical purposes, they can be used interchangeably in the same system.
Specification: Same hardware, same backup operation, same audio quality.
The 100V backup input is designed for 100V line-level signals from a traditional paging amplifier or fire alarm system. Do not connect speaker-level outputs directly. The T-7707D's internal amplifier drives the speakers; the 100V input is just a signal source. Ensure backup amplifier volume is set appropriately.
The T-7707D can be configured to meet EN54 and other life safety standards when used with appropriate backup sources. Consult with your system integrator for specific compliance requirements in your region.
Primary: T-7700 Server → PoE Switch → T-7707D (network audio)
Backup: Fire alarm panel → 100V paging amp → T-7707D backup input
During normal operation, audio is from network for daily pages. If network fails, speaker instantly switches to 100V backup, ensuring fire alarms are always heard.
