The Apollo 55000-760APO is a compact, loop‑powered XP95/Discovery/CoreProtocol compatible mini switch monitor for addressable fire systems. Designed for installations with limited space, it mounts on a 35 mm DIN rail or inside small enclosures and manual call point housings. It monitors one or more single‑pole volt‑free contacts on a single pair of wires and reports four input states to the control panel: normal, fault, pre‑alarm and alarm. Supports priority (interrupt) and non‑priority operation.

• Compatibility: XP95, Discovery, CoreProtocol loops (5–9 Vpp signalling).
• Mounting: 35 mm DIN‑rail or small enclosures/manual call point housings.
• Input: Single‑pair, single‑pole volt‑free contact monitoring.
• States & modes: Normal, Fault, Pre‑alarm, Alarm; priority (interrupt) & non‑priority modes.
• Certifications: EN54‑17 & EN54‑18 (loop interface / short‑circuit isolation); CPR, LPCB, VdS (see datasheet for full regional approvals).
• LED indication: Visible LED for status (normal/fault/alarm).

Important: Exact installation figures (quiescent currents per LED state, required end‑of‑line resistor, maximum cable loop resistance, power‑up surge/time) must be taken from the official Apollo datasheet during design/installation. Installation and commissioning must be carried out by a qualified fire systems installer to comply with applicable regulations and approvals. This unit is intended for use with compatible addressable fire control panels; check panel compatibility and software addressing procedures before installation.
