Lift and alarm emergency phones depend on constant connectivity. OV provides global IoT SIM and eSIM solutions with multi-network failover, two-way voice, and number ownership built for compliance-critical devices.
In a stalled lift, every second counts. OV keeps lift, alarm and critical-device emergency phones connected with global multi-network coverage, automatic network failover, and visibility through OV ONE. Our connectivity supports two-way voice communication, VoLTE-based calling, and numbers you own and control outright.
When a lift or alarm emergency phone loses its network, calls fail and compliance is compromised. You need reliable, multi-network coverage, numbers you control, and full lifecycle visibility.
EN 81-28 requires a permanently staffed two-way voice connection in every EU/UK lift, with a mandatory test call at least every three days. ASME A17.1 requires the same two-way emergency communication in every US elevator cab. AS 1735 sets an equivalent requirement in Australia. None of that has changed. What’s changed is the network underneath it: copper PSTN lines and older mobile networks that many lift and alarm emergency phones still depend on are being retired on published schedules across the EU, US and Australia.
A retired network doesn’t remove the compliance obligation, it removes the connection the system was relying on to meet it, turning a routine network change into an inspection-failure and liability risk.
OV’s IoT SIMs and eSIMs provide resilient, redundant connectivity with coverage across 180+ countries and 600+ networks. Automatic network failover keeps emergency calls connected even when a primary network fails or is retired. With OV’s solution for lift and alarm connectivity, you get:
180+ countries and 600+ networks for truly global asset visibility
Full voice support for two-way emergency communication
VoLTE and multi-network resilience for compliance-critical devices
Real-time device status monitoring via OV ONE
Lift and alarm emergency phones must keep working to the standard required, regardless of what happens to the network underneath them. OV ONE gives you visibility and control designed for compliance-critical applications.
Emergency Communication Features We Support:
Connectivity Features for Compliance-Critical Devices:
Lift and alarm emergency phones must work when someone is depending on them. OV’s infrastructure prioritises reliability, redundancy and continuity of voice service as legacy networks retire.
Device Type Support:
Technical Features:
Integration Capabilities:
From single-site passenger lifts to multi-country facilities management portfolios, OV provides the connectivity infrastructure for reliable emergency communication and compliance.
Deployment Scenarios:
These are the EU/UK, US and Australian standards requiring a permanently staffed, two-way emergency communication path in every lift. EN 81-28 also requires a mandatory test call at least every three days.
Devices must support LTE and VoLTE. If your existing devices only support 2G or 3G, new hardware will be required.
OV’s Multi-IMSI technology automatically switches to the next available network, keeping emergency calls connected.
The solution is designed to support the two-way communication requirements in these standards. Compliance sign-off remains the responsibility of the lift owner or their nominated inspection body.
Yes. OV ONE provides real-time visibility of connection status, signal strength and device health, allowing proactive maintenance.
When a lift or alarm emergency phone needs to work, connectivity cannot fail. OV provides the multi-network resilience, number ownership and real-time monitoring to keep compliance-critical devices connected worldwide.
