2. Mounting

2.1 Prerequisites

To operate the NRT, at least one analogue telephone connection in one of the following versions

is required:

• Analogue telephone main connection

• Analogue extension of a telephone system

• Telegärtner GSM gateway

The transfer point (TAE socket) should be in the machine room or near the clamping point of the

suspension cable.

The telephone connection must be reserved exclusively for the NRT, i.e. no other dialling devices

(such as modems or fax machines) may be connected to the same connection.

Two free wires in the suspension cable are required for the telephone line. In order to avoid inter-

ference, twisted pair and shielded cables must be used.

An uninterruptible power supply of 24V DC must be provided for NRT. Alternatively, an uninter-

ruptible power supply is available from Telegärtner as an additional device (Art. No. 601364).

2.2 Mounting location

The emergency call device is intended for mounting on the roof of the lift car.

The loudspeaker is to be placed in such a way that sufﬁcient acoustic sound coverage of the car

and the lift shaft is ensured.

2.3 Telephone line

Route the telephone cable from the machine room to the NRT via the suspension cable and con-

nect it to clamp 21 and 22 on terminal block XD1. The polarity does not need to be observed.

We expressly point out that interference on the voice connection may occur if

no separate suspension cable or shielded wire pair is used in the suspension

cable.

2.4 Loudspeaker / Microphone

Depending on the model, the loudspeaker is mounted either on the cabin roof or as a ceiling

The shield of the microphone cable is connected to a free clamp “PA”.

Connect only one device at a single input for the microphones or output for the

loudspeaker.

The microphone used must be “Microphone NRT 1 EX G3”, Art. No. 601361!

2.5 Emergency call buttons

Up to two potential-free emergency call buttons can be connected directly to the NRT.

call from the roof of the elevator car.

The connected emergency buttons must switch the input potential-free!

The following table shows which emergency button activates which microphone:
