Description
The Apollo XP95 55000-847 Input/Output Module is engineered to maintain safety integrity and facilitate seamless interfacing between addressable fire alarm control panels and auxiliary building systems. Capable of monitoring switch inputs—such as sprinkler flow switches, fire doors, and gas shut-off valves—and driving external hardware via a single pole changeover relay, this module serves as a critical bridge for emergency automated control actions. Constructed in a durable surface-mounting enclosure with an integrated bidirectional short-circuit isolator, it protects the addressable loop circuit from fault disruptions while offering visible LED status indication for input, output, and isolator states.
Features
- Provides 1 supervised switch input and 1 voltage-free relay output for complex fire cause-and-effect matrix integration
- Built-in short-circuit isolator protects loop wiring by isolating shorted cable sections without interrupting loop communication
- Fully compatible with Apollo XP95 and Discovery digital addressable protocols for precise device identification and status report
- Multi-state LED indicators give immediate visual verification of input status, relay activation, and short-circuit fault conditions
- Surface-mount enclosure includes knockout cable entries for efficient installation and clean wiring management
