Emergency Phones in Telecommunication

Notruftelefone

Emergency phones enable direct connection to rescue control centres, plant security or security personnel, and are required in public buildings, underground car parks, on platforms and in tunnels. Standard EN 50518 defines requirements for emergency communication centres; VDE 0833 additionally applies to hazard detection systems. Emergency phones must automatically dial the control centre with a single button press (one-touch) and include battery backup for mains failures. FHF and Grothe offer a wide range of weatherproof, vandal-resistant emergency phones for outdoor and indoor use, connectable via SIP or analogue interfaces.

Frequently Asked Questions

▶ What does EN 50518 require for emergency phones?

EN 50518 defines technical and organisational requirements for emergency communication centres. Relevant for endpoints (emergency phones): fail-safe connection, backup power, clear location identification (call origin display), audio quality at least to ITU-T G.711, and call recording capability. The specific implementation depends on the control centre connection.

▶ Do I need an emergency phone in an underground car park?

In publicly accessible underground car parks above a certain size (regulations per regional building code), emergency phones are required. Typically: mandatory from 20 parking spaces, at least one emergency point per floor or section. GSM-based emergency phones are particularly suitable as they eliminate cabling effort. Verify the specific requirement with your local building authority or fire safety engineer.

▶ What is the difference between an emergency phone and an intercom?

An emergency phone automatically dials a predefined emergency number – typically the control centre or plant security – with a single button press or even automatically on tamper detection. An intercom allows bidirectional communication between two fixed points (e.g. door and gatehouse) without connection to a control centre. Both systems can be combined.
