Apollo 55000-885APO (XP95) multisensor detector combining photo‑electric smoke sensing with a thermistor temperature sensor. Designed for indoor addressable loops, it uses on‑board processing to fuse smoke and heat inputs for reliable detection of both smouldering and flaming fires while reducing nuisance alarms.

• Multisensor detection: photo‑electric (light scattering) smoke + thermistor temperature.
• XP95 analogue addressable protocol with analogue value reporting (nominal value 23).
• Two‑wire, polarity‑insensitive loop connection with remote LED terminals.
• Wide operating range: -20°C to +60°C; humidity 0–95% RH (no condensation/icing).
• Low quiescent current (~500 µA average); compact white polycarbonate housing (≈100 mm Ø).
• Approvals include EN54‑7, LPCB, VdS, CPR and UL. Manufacturer warranty: 10 years.

Ideal for bedrooms, hotels, offices, retail and other medium/large indoor spaces. Installers: use XP95 compatible bases (e.g. Apollo 45681‑210) and follow panel manufacturer guidance for drift compensation and commissioning. Refer to the official Apollo datasheet and installation manual for full installation instructions, IP rating confirmation and compatibility notes.

Safety & compliance: Use only in accordance with the manufacturer datasheet and current UK/EU installation standards. Ensure correct base and wiring; consult control panel manufacturer for compatibility and drift compensation settings.
