Why POTS Link Is the #1 POTS Replacement for Security Alarm Systems
Alarm Systems Weren’t Designed for VoIP. That’s a Problem.
Thousands of intrusion alarm systems across the U.S. still rely on analog POTS lines to signal central stations. But as carriers rapidly dismantle copper infrastructure and the FCC eliminates support obligations, security integrators, facilities teams, and building owners are facing a high-stakes transition:
How do you replace your alarm POTS lines without compromising reliability, compliance, or central station connectivity?
The answer isn’t a makeshift VoIP adapter or an off-the-shelf cellular gateway.
The answer is POTS Link—a fully managed, life-safety-grade POTS replacement that was purpose-built to support security alarm transmission with zero disruption to protocol or panel behavior.

Security-Grade Reliability for Critical Alarm Communications
Security-Grade Reliability for Critical Alarm Communications
POTS Link provides a 1:1 analog line replacement that allows your existing alarm panel to operate exactly as it did over copper:
- No panel reprogramming required
- No compatibility issues with DTMF or pulse dial signaling
- No skipped or dropped signals to your monitoring center
Whether your system communicates via Contact ID, SIA, or other legacy formats, POTS Link preserves signal fidelity and ensures your panel’s dialer behaves predictably.
Built for Central Station Compatibility
Most security alarm systems are only as good as the communication path between the panel and the central station. POTS Link ensures that path stays fast, accurate, and compliant:
| Security Requirement | POTS Link Delivers |
| DTMF Tone Integrity | Transparent analog emulation preserves dialer tone sequences |
| Contact ID / SIA Protocols | Fully supported without firmware or hardware modification |
| Alarm Signal Prioritization | Works with carrier Wireless Priority Services (WPS) |
| Supervised Line Status | Real-time alerts and out-of-band device health monitoring |
| UL-Central Station Compatibility | Plug-and-play with most receiver formats |
Your alarm system will connect to the central station just as it did with a copper line—without a single protocol lost in translation.
No Rewiring. No Risk. No Guesswork.
Unlike cheap VoIP adapters or LTE modems, POTS Link is a turnkey solution:
- RJ11 analog interface—just plug in your alarm panel’s dialer
- 24-hour battery backup standard for alarm code compliance
- Primary LTE connectivity with optional wired or satellite failover
- Remotely managed, monitored, and supported by experts
It’s a drop-in replacement designed for speed, safety, and simplicity.
POTS Link Alignment with UL 681 / UL 864 Requirements
When replacing analog POTS lines supporting burglar alarm systems (UL 681) or combination fire/security panels (UL 864), maintaining signaling integrity and system compliance is essential.
POTS Link was engineered to meet or exceed the functional requirements defined in these UL standards, giving inspectors and integrators confidence in both performance and code adherence.
UL 681: Standard for Installation and Classification of Burglar and Holdup Alarm Systems
| UL 681 Requirement | POTS Link Compliance |
| Reliable communication path between alarm panel and central station | POTS Link provides a transparent analog handoff over LTE or dual-path transport, ensuring uninterrupted alarm transmission. |
| Support for DACT (Digital Alarm Communicator Transmitter) over telephone lines | Fully compatible with Contact ID, Pulse, and SIA formats. Alarm panels communicate using their native DACT settings—no changes required. |
| Line supervision and fault detection | Includes remote heartbeat supervision, line status reporting, and alerting in case of communication loss or path degradation. |
| Standby power | 24-hour internal battery backup meets UL expectations for maintaining power during an AC failure event. |
UL 864: Standard for Control Units and Accessories for Fire Alarm Systems (Applies to combo panels)
| UL 864 Requirement | POTS Link Compliance |
| Survivability of communication path | Dual-path options (LTE + WAN/SATCOM) ensure message delivery continuity in the event of network failure. |
| Compatibility with fire alarm DACTs | Supports pass-through of alarm tones with no packetization or delay—required for decoding by UL-listed receivers. |
| Supervised communication line with automatic failure reporting | Real-time monitoring and SNMP/API integration for external supervision systems. |
| No interference with panel operation | POTS Link emulates a standard RJ11 copper line—completely transparent to the fire/security control panel. |
| Response to AC failure | Built-in AC loss detection triggers internal alerts and engages battery backup. |
