Apollo XP95 Sounder VAD Base ISO White | 45681-705 (F/45681-705)

Loop Powered Fire Alarm Sounder and Visual Alarm Device

The Apollo 45681-705 XP95 Sounder VAD Base combines a standard detector mounting base with a loop-powered sounder and visual alarm device (VAD), designed to provide clear audible and visual fire alarm alerts in enclosed environments.

This intelligent alarm base can be installed with an Apollo XP95 or Discovery detector, or fitted with a cap to operate as a standalone alarm device. Its loop-powered design removes the need for external power supplies, simplifying installation while reducing overall system costs.

Available from Alert Electrical, a trusted UK supplier of professional fire safety and electrical installation products.

Integrated Audible and Visual Alarm

The XP95 Sounder VAD Base delivers both audible fire alarm tones and high-visibility visual signalling, ensuring occupants are alerted quickly during emergency situations.

The integrated visual alarm device provides a Category O VAD output, making it suitable for a wide range of indoor applications where visual alarm notification is required.

Flexible Volume and Alarm Settings

The device offers adjustable volume levels and synchronised alarm tones to ensure effective signalling across different environments.

Sounder features include:

• Two selectable volume ranges
• 55–75 dB(A) for lower noise environments
• 75–91 dB(A) for louder environments
• Synchronised alert and evacuate tones

This flexibility allows installers to configure the alarm output based on the building layout and application requirements.

Advanced Self-Test and Synchronisation

The XP95 Sounder VAD Base incorporates innovative self-testing functionality, helping ensure reliable operation without requiring additional testing equipment.

Advanced features include:

• Acoustic self-test for the sounder
• Visual self-test for the VAD
• Synchronised alarm tones across multiple devices
• Individual or group addressing via the fire alarm loop

These capabilities help maintain system reliability and simplify maintenance procedures.

Loop Powered Design with Built-In Isolator

Because the device is loop powered, it draws power directly from the fire alarm loop circuit. This eliminates the need for additional power supplies and simplifies wiring during installation.

The integrated short-circuit isolator improves system resilience by protecting the loop in the event of a fault.
