PN1 2-wire converter — network and power over an existing two-core cable

A 2-wire converter that carries network and power over a two-core cable, so a building can be served without pulling new network cabling. The product materials tie it to historical building retrofit.

Supplies network and power over a two-core cable
Extends PoE wiring over 2-wire, so cabling already in the building can be reused
Maximum transmission distance up to 1600 m for the network function, without power
External power supply at AC 100–240 V
The product materials label the converter with historical building retrofit
Built for sites where two-core cable exists but network cabling does not

PN1 2-wire converter used to carry network and power over existing two-core cable

Retrofit without new cabling

In an older building the two-core cable is often already in the walls, and pulling new network cable through the fabric is the expensive part of the job. The PN1 uses the cable that is there: it supplies network and power over the two cores, and extends PoE wiring over 2-wire.

Network and power over the same two-core cable
Extends PoE wiring over 2-wire
The materials label the unit with historical building retrofit
External power supply at AC 100–240 V

This model is a converter in the 2-wire line, alongside a 2-wire switch for up to eight devices and a 1U model for up to 24 devices; those are quoted separately.

Distance and power

The published distance figure is a long one, and it comes with a condition: it is stated for the network function only, without power.

Maximum transmission distance up to 1600 m for the network function, without power
Power comes from an external AC 100–240 V supply at the converter
A maximum distance with power over the two cores is not stated for this model
The two-wire device count for this unit is not stated

The 1600 m figure applies to the network function alone. If you need a distance rundown with power on the same pair, tell us the site layout and we will confirm it against the current documentation.

What the materials do not state

SIP lines — this is a cabling device, not a SIP endpoint
Dimensions and weight — not stated in the source materials
Ingress protection and operating temperature — not stated in the source materials
Mounting method — not stated in the source materials
Endpoints that can sit on the far end — confirm the model with us before you specify

Where a fact is missing we say so rather than guess; the retrofit chain is confirmed per project on the quotation.

Where it fits on site

Historic or listed building

The materials tie this converter to historical building retrofit, where the cabling in the fabric is kept and reused.

Site whose walls already carry two-core cable

The converter supplies network and power over the existing pair instead of a new network run.

Long or awkward cable routes

Network transmission up to 1600 m is stated on the two-core cable, with power on a separate external supply at the converter.

iSpecifications are taken from the 2-wire product documentation supplied with the range. The 1600 m figure is stated for the network function only, without power; dimensions, weight, protection ratings and mounting are not stated. The same documentation covers a 2-wire switch for up to eight devices and a 1U model for up to 24 devices — those are quoted separately.

Compatibility boundaries

This model uses standard SIP and the interfaces listed in the specification table. Confirm the PBX, SIP provider or platform against those interface notes before the order; where the documentation does not state a value, the table records it as not stated rather than estimating. PoE, analog port variants, power options and card compatibility are fixed at order time.

Handover, spares and support

Extension plan, provisioning and interface language can be prepared before dispatch. Remote support continues after handover. Spare-part, warranty and service terms are confirmed in the quotation for the models and quantity ordered, so they are not printed as a single figure here.

Where it sits in the system

SIP desk phones

Phones at the far end of the two-core run register over SIP as usual.

Door phones & intercom

Entrance terminals fed over the same retrofit cabling.

Apartment buildings

Building retrofits where the existing cable is reused.

Frequently asked questions

Do we have to re-cable the building?

That is what the converter is for. It supplies network and power over a two-core cable and extends PoE wiring over 2-wire, and the product materials label it with historical building retrofit — so the cabling already in the building can be reused rather than replaced.

How far can the two-core run go?

Up to 1600 m is stated for the network function, and the source adds the condition that this is without power. A maximum distance with power over the same pair is not stated for this model, so tell us your run lengths and we will confirm on the quotation.

How is the converter powered?

From an external power supply at AC 100–240 V.

Which devices can sit at the far end?

The materials document the 2-wire line as the retrofit route and also cover a 2-wire switch for up to eight devices (PN8 in the materials) and a 1U model for up to 24 devices (PN24). Both are quoted separately. The endpoint mix is confirmed per project — send us the device list and the cable runs and we will check it.
