Apollo XP95 Input / Output Unit with Isolator (55000-847APO)

The Apollo Input/Output Unit (55000-847APO) provides a reliable interface between an addressable fire alarm system and external equipment. The unit combines a voltage-free double-pole changeover (DPCO) relay output, a single monitored switch input, and an unmonitored non-polarised opto-coupled input, making it fitting for a wide range of monitoring and control applications.

The 55000-847APO allows the fire alarm system to monitor external devices and control connected equipment through its relay output. The built-in short-circuit isolator helps maintain loop operation by curbing the impact of wiring faults and making overall system reliability better.

The unit draws power directly from the addressable loop, removing the need for a separate power supply and making installation simpler. Three visible LEDs provide clear status indication, helping engineers and maintenance personnel to quickly check the operating condition of the unit.
