Alarm Multiplexer
Extend one alarm signal to multiple NMS systems — safely, with full electrical isolation.
Many telecom infrastructure companies now share passive infrastructure among multiple cellular operators, reducing capital and maintenance costs. However, when the same alarms need to be monitored by more than one operator, a challenge arises.
Spaceage Security's Alarm Multiplexer solves this by extending a single alarm to multiple Network Management Systems (NMS), each with complete electrical isolation — ensuring that faults remain localized to a single operator's domain.
The unit supports varied voltage standards (e.g., -5V DC to +3.5V DC), uses a dedicated power source, and has been successfully deployed in critical environments including Delhi Metro underground stations.

Where It's Used
Shared BTS Infrastructure
Multiple telecom operators sharing a single tower site — each needs independent NMS alarm monitoring.
Metro & Underground
Successfully deployed at Delhi Metro underground stations where alarm sharing is critical for safety.
Multi-Tenant Data Centres
Environments where alarms must be distributed to multiple tenants' monitoring systems independently.
NOC / TOC Centres
Network operations centres that need alarm signals split across multiple monitoring platforms.
