Cisco BC-512011 Alarm Relay Interface (ari) Back Ca

Overview
The Cisco Alarm Relay Interface (ARI) Back Ca, part number BC-512011, is a compact and reliable module that enables seamless integration of external alarm devices with Cisco network infrastructure. Designed for mission critical environments, this interface provides a secure, low-latency path for alarm signals to be transmitted to Cisco routers, switches or firewalls, allowing centralized monitoring and rapid response to security events.

Key Features

• Two independent relay contacts for versatile alarm signal handling
• Supports dry-contact and wet-contact alarm sources
• Isolation voltage up to 2500 V AC to protect network equipment
• LED indicators for power, alarm status and fault detection
• Plug-in form factor compatible with standard Cisco chassis slots
• Simple configuration through Cisco IOS CLI or web interface

Technical Specifications

• Model/Part Number: BC-512011
• Operating voltage: 24 V DC (typical)
• Contact rating: 5 A at 250 V AC
• Isolation: 2500 V AC between contacts and chassis
• Temperature range: -20 to 70 degrees Celsius
• Dimensions: 1.75 in (H) x 4.5 in (W) x 0.8 in (D)
• Power consumption: less than 2 W
• Compliance: FCC Part 15, CE, RoHS

Applications
The ARI Back Ca is ideal for security and building management systems where alarm events must be relayed to the network for logging, notification or automated response. Typical deployments include:

• Fire alarm panels interfacing with network monitoring stations
• Intrusion detection systems sending breach alerts to security operations centers
• Environmental sensors (water leak, temperature) triggering network-based alerts
• Industrial control systems requiring reliable alarm signaling to supervisory software

By integrating the Cisco Alarm Relay Interface into your infrastructure, you gain a robust bridge between physical alarm hardware and modern IP-based management tools, enhancing situational awareness and reducing response times.
