XP95 SOUNDER VAD BASE CAT. O (WHITE FLASH) – ISOLATING 45681-705APO

The Apollo XP95 Sounder VAD Base with Isolator (45681-705APO) combines a loop-powered sounder, an EN54-23 approved Visual Alarm Device (VAD), and a standard intelligent mounting base into a single unit. Designed for use with Apollo XP95 addressable fire alarm systems, the device provides both audible and visual alarm notification in enclosed areas while helping to simplify installation and system design.

The 45681-705APO delivers synchronised sound and visual signalling across the fire alarm loop, ensuring occupants receive a consistent alarm warning throughout the building. It can be installed with a compatible detector fitted or used with a cap as a stand-alone alarm device, providing flexibility for a wide range of applications.

A key feature of the XP95 Sounder VAD Base is its integrated self-test functionality. When activated, the device automatically verifies both sounder operation and VAD performance. If a fault is detected, the base reports an analogue value to the control panel, allowing maintenance personnel to quickly identify and rectify issues. This feature simplifies commissioning, routine inspections, and ongoing maintenance.

Furthermore, the integrated short-circuit isolator helps maintain loop integrity by isolating faulted sections of the circuit, minimising disruption to the wider fire alarm system.

Self-Test Function

The integrated self-test feature automatically checks sounder and visual alarm operation when activated.

Possible fault responses include:

• Analogue Value 1 – Sounder fault (no sound detected within 5 seconds)
• Analogue Value 2 – VAD fault (no current drawn by the LEDs)
• Analogue Value 3 – Combined sounder and VAD fault

This functionality can also be used during commissioning and routine maintenance by activating the device for at least five seconds and checking the control panel for fault indications.
