The T-7707AB 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 – essential for hospitals, schools, and government buildings.
The T-7707AB is a wall-mounted IP active speaker with a critical differentiator: a 100V analog backup input. It combines the convenience of network audio with the fail-safe reliability of traditional 100V paging systems, making it ideal for life-safety and mission-critical applications.
Why 100V Backup? In hospitals, schools, government buildings, and industrial facilities, emergency announcements must be heard regardless of network status. The T-7707AB 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. Can be mixed with network audio.
Single Ethernet cable for data and power. No electrician required for installation.
| Condition | Audio Source | LED Indicator |
|---|---|---|
| Normal operation | Network streaming (IP) | Green (network) |
| Network failure / no signal | Automatic switch to 100V backup input | Amber (backup active) |
| Network restored | Automatic return to network | Green |
| Manual override | AUX input selected via software | Blue (power) |
Automatic failover
Network → 100V backup
<0.5 seconds
| Parameter | Value |
|---|---|
| Frequency Response | 80Hz – 18kHz (±3dB) |

Network: announcements, bells
Backup: emergency evacuation system
Network: shift change music
Backup: emergency alert system
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-7707AB's internal amplifier drives the speakers; the 100V input is just a signal source. Ensure backup amplifier volume is set appropriately.
The T-7707AB 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-7707AB (network audio)
Backup: Fire alarm panel → 100V paging amp → T-7707AB 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.
