SIP emergency telephone for tunnels and portals
After an accident, a vehicle breakdown or a fire, this is where a driver can speak with the control center. Lifting the handset or pressing a single button is enough; the call is sent to the PBX over the IP (SIP) line.
A tunnel is dusty and humid. D and DS Series telephones have an IP66 rating once installation is complete; the LMD-12 enclosure is also IP66 and TSE certified.
The D Series has an aluminum alloy enclosure, is vandal-resistant and comes with a steel-armored cord. The DS Series is made from a single aluminum casting with electrostatic powder coating.
The telephones run on an IP (SIP) line. All Limpid products work on the same PBX and cabling, so the system can be extended along the whole tunnel.
Telephones mounted on the wall inside the tunnel, and telephones protected by a shelter at entrances and portals: our products are ready for both.

Some of the projects where Limpid telephones are in service in road tunnels.
It is a fixed telephone inside and at the entrances of a tunnel that lets a driver or pedestrian speak with the control center during an incident. Lifting the handset or pressing a single button is enough; the call is sent to the PBX over the IP (SIP) line.
A tunnel is dusty and humid. Limpid D and DS Series telephones have an IP66 rating once installation is complete; the LMD-12 enclosure is also IP66 and TSE certified. The required IP rating is set by the project specification.
The spacing is set by the project specification. In road tunnels, it is common practice to place a telephone every 100 meters inside the tunnel.
The most popular color is orange, which stands out in tunnels (RAL 2004, traffic orange). Yellow (RAL 1023, traffic yellow) and red (RAL 3020, traffic red) can also be chosen.
Shelters are available for tunnel entrances: the ground-mounted and wall-mounted LMD-01, the LMD-03 with a base, and the LMD-02 acoustic shelter with 20 dB sound reduction for noisy locations. The telephone is installed inside, together with an enclosure if desired.
