Keep fire alarm panels reporting
even when IP service is down.
When IP service is down, the fire system or fire phone uses a Redstone FXS/FXO path to dial a preset external fire notification number over PSTN.
Why Fire Alarm Systems Need POTS Replacement
Fire alarm panels and fire phones depend on analog lines for central station reporting. When copper is retired, the reporting path must survive.
Copper Lines Being Retired
Fire alarm panels that rely on analog phone lines for central station reporting lose their connection path when carriers retire copper.
NFPA 72 Requirement
Fire alarm systems must maintain a reliable communication path to the monitoring station. This path cannot depend on IP availability alone.
PSTN Backup When IP Is Down
When IP service is down, the fire system uses a Redstone FXS/FXO path to dial a preset external fire notification number over PSTN.
How the Redstone Solution Works
The fire alarm panel or fire phone connects to a Redstone REX or RGW via FXS. The FXO port provides a PSTN failover path when IP is unavailable.
What Must Be Preserved
Fire alarm communication has specific requirements that must continue to work after POTS replacement.
Real-World Scenario
See how the Redstone solution applies in a real deployment environment.
Designed for Your Environment
The Redstone gateway integrates seamlessly with your existing infrastructure. No device replacement, no workflow change — just a modernized connection path with reliable backup.
A Lower-Disruption Alternative
The right path depends on the fire panel type, monitoring requirements, and the available backup path.
Complete Fire Panel Replacement
Rip-and-replace approach
- Replace the existing fire alarm panel
- Permitting and inspection required
- Possible building fire watch
- Higher upfront investment
- New monitoring contract needed
Redstone POTS Replacement
Keep the panel. Replace the line.
- Use existing fire alarm panel
- No panel modification needed
- FXS/FXO failover: PSTN when IP is down
- NFPA 72 compliance maintained
- Lower cost, faster deployment
Validate the Fire Alarm Reporting Path
Acceptance should confirm the fire alarm panel can report to the central station through both primary and backup paths.
The Continuous Value Path
POTS replacement is only the first step. The same platform can later support remote monitoring, centralized alarm management, and predictive maintenance.
Endpoint Reuse
Retain existing fire panel
Replace only the connection path
Platform Upgrade
Connect IP communications
Centralized alarm monitoring
Smart Services
Predictive maintenance
Alarm analytics and reporting
