Apollo 45681-276APO XP95 ancillary base sounder — loop‑powered local sounder for detector‑activated signalling in addressable fire systems. Fits compatible XP95, Discovery or Soteria detectors (or loop‑powered beacons) and is powered/switched via the detector's remote output so it does not require a separate address.

• Loop‑powered: 17–28 V DC (no external supply required).
• Guaranteed sound output 85 dB(A) at 1 m; stepless/adjustable down to ≈70 dB(A).
• Very low quiescent current (~100 µA) and low operating (sound) current (~3 mA) — allows many units per loop.
• White flame‑retardant polycarbonate housing, IP23D; operating temperature −20 °C to +60 °C.
• EN54‑3 (sounder) compliant; intended for indoor local‑area signalling.

Use cases: detector‑activated local notification in commercial and residential installations where a local, address‑free audible indicator is required. Suitable for retrofits and new installations where panel programming uses the detector remote output to drive ancillary sounders.

Installation & compliance notes: as an ancillary (non‑addressed) sounder it is activated via the detector's remote output. Confirm that the fire alarm control panel and detector configuration support the remote output bit used for ancillary sounders. Refer to Apollo installation manual (PP2148) and panel commissioning guide for wiring, loop‑loading calculations and cause‑and‑effect programming. Ensure installation meets local regulations and EN54 requirements.
