EST Edwards SIGA-IB Fire Alarm Mounting Base with Fault Isolator. This specialized mounting base integrates advanced fault isolation technology directly into your life-safety system architecture. - Operating Voltage: 15.2 to 19.95 VDC - Standby Current: 45 µA - Alarm Current: 45 µA - Isolation Resistance: 10 MΩ - Operating Temperature Range: 32°F to 120°F

Engineered to replace standard mounting solutions, the SIGA-IB offers a more robust path to system integrity compared to traditional non-isolating bases. While earlier models required separate modules to manage short-circuit protection, this unit combines mounting functionality with built-in fault isolation to ensure that a single wire fault does not compromise the entire notification or detection loop.

Advanced Circuit Protection and System Reliability

The SIGA-IB is designed to maintain high performance in demanding commercial fire alarm environments. By detecting a short circuit on the Signaling Line Circuit (SLC), the base automatically isolates the affected segment, allowing the rest of the system to continue operating without interruption. This intelligent design reduces maintenance downtime and ensures that life-safety monitoring remains active across your facility even during localized electrical faults. Its low power consumption profile makes it an efficient addition to any Edwards Signature Series configuration, providing reliable, automated protection that meets modern safety standards.
