Apollo 45681-705APO is a loop‑powered XP95 addressable combined sounder and visual alarm device (VAD) mounting base with an integral isolator. It provides selectable audible tones and volume ranges together with a white‑flash VAD (EN54‑23 Category O), and is intended for indoor fire‑alarm notification in XP95/Discovery/CoreProtocol systems.

• Loop‑powered XP95 addressable sounder + VAD base with built‑in isolator (EN54‑17 4" isolated base).
• EN54‑3 (sounder), EN54‑23 (VAD Category O) and EN54‑17 (isolator) compliant.
• Selectable tones and volume ranges; synchronised tone and VAD flash across groups.
• Self‑test functions for acoustic and VAD operation.
• 10‑year manufacturer warranty (Apollo).

Typical uses: notification base for addressable fire panels in commercial and public buildings where combined audible and visual signalling is required. Suitable for new installs or retrofits where XP95/Discovery protocol detection systems are used.

Installation & safety: must be installed and commissioned by a competent person in accordance with the installation manual and current national regulations. Follow Apollo's datasheet/installation guide for loop wiring, addressing and synchronisation settings. Ensure correct volume selection for the application; note some low range settings are not EN54‑3 compliant for re‑alarm uses.

Compliance & certification: CE/UKCA/CPR references apply as shown on Apollo documentation—check the product datasheet for declarations of conformity and applicable approvals before installation.
