The T-7707DH is the only T-7707 model combining 2x30W high-power amplification with a 100V analog backup input. Ideal for large spaces where both high volume and fail-safe emergency announcements are required.
The T-7707DH is the flagship life-safety speaker in the T-7707 family, combining high-power 2x30W amplification with a 100V analog backup input. It's designed for large, critical spaces where both high volume and fail-safe emergency announcements are essential.
High Power + Backup – The Best of Both Worlds: This model delivers the high power needed for large spaces (2x30W) plus the peace of mind of automatic failover to a 100V analog source. Perfect for:
100V Analog Backup: If the network fails, the speaker automatically switches to the 100V backup input within 0.5 seconds, ensuring emergency announcements are always heard.
AUX Input: Connect local audio sources such as media players, TVs, or emergency notification systems.
Easy Installation: Powered by PoE (802.3af) – a single Ethernet cable provides data and power. For maximum 30W output, the optional 24V DC adapter is recommended.
Double the power of standard models. Fills large spaces with clean, intelligible audio.
Automatic failover to analog paging during network failure. Critical for life-safety applications.
Connect local audio sources: media players, TVs, or emergency notification systems.
Single Ethernet cable for data and power. Optional DC adapter for full 30W output.
| 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 |
Automatic failover

Ideal for large spaces
Backup path uses same amplifier – no quality loss
The T-7707DH's 2x30W amplifier draws more power than standard models. When using PoE (802.3af), available power is approximately 15W per channel – sufficient for most speech and background music. For maximum 30W per channel output, use the optional 24V DC adapter. The backup circuit operates regardless of power source.
| Model | Power | AUX | 100V Backup | Wireless |
|---|---|---|---|---|
| T-7707AB | 2x15W | Yes | Yes | No |
| T-7707D | 2x15W | Yes | Yes | No |
| T-7707DH | 2x30W | Yes | Yes | No |
The T-7707DH is the only T-7707 model that combines high power (2x30W) with 100V analog backup. Compare to:
Choose T-7707DH when you need both high volume and fail-safe emergency backup.
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-7707DH's internal amplifier drives the speakers; the 100V input is just a signal source. Ensure backup amplifier volume is set appropriately.
The T-7707DH 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-7707DH (network audio)
Backup: Fire alarm panel → 100V paging amp → T-7707DH backup input
During normal operation, audio is from network for daily pages and background music. If network fails, speaker instantly switches to 100V backup, ensuring emergency alerts are always heard. Optional DC adapter used for full 30W output to cover large waiting area.
