As traditional PSTN lines phase out worldwide, alarm systems built decades ago face a new challenge: how to stay connected in an all-IP world. The Contact ID Relay from Vola offers the perfect bridge — enabling legacy alarm panels to communicate reliably through modern cellular or IP networks, without replacing the existing infrastructure.

Designed to interpret and relay Contact ID signals, this compact module ensures that alarms continue to reach the monitoring station through the latest communication channels. It provides a direct and secure conversion from analog dial tones to digital messages, maintaining signal integrity and timing accuracy — two critical aspects for UL and NFPA compliance.

For central stations and integrators, the transition to IP has never been smoother. Contact ID Relay eliminates the need for rewiring or panel upgrades. It’s plug-and-play, adaptable to various alarm panels, and supports flexible routing through VPNs or managed voice networks (MFVN).

This approach future-proofs legacy systems, extending their operational life and reducing upgrade costs. It also supports hybrid topologies where both PSTN and IP coexist — ensuring business continuity through redundancy and reliability.

As the world moves toward all-IP communication, the Contact ID Relay stands as a practical, scalable, and compliant pathway forward — bridging yesterday’s systems with tomorrow’s connectivity.

Smart transition. Zero disruption. Contact ID Relay keeps alarms talking.
