Technical Specifications

tart-up

• Fix the device at the wall with two

crews (Ø 8 mm).

• To correct the distance between the

orn and the wall use the supplied

spacer.

• Remove the housing cover. If the

setting of the volume and/or signal

tones do not meet your require-

ents, you have the following

options according to „Setting of

volume and signal tones“

• Enter the connecting cable through

he cable and wire gland (KLE).

• Connect the wires to the clamps

according to connection diagram

(on page 4 + 5). Tighten the housing

cover.

• Pull the cable excess of the terminal

compartment through the KLE and

fix the wire with the gland nut of the

KLE.

Setting of volume and signal tone

To set volume and signal tones the

cover of the housing has to be remo-

ved. The electrical plug connection to

the bottom section can be cut. In the

upper section the setting can be

carried out at the 12 slide switches.

The sounder dEV20 disposes of two

signal levels. The signal tone for the

first level is adjusted with the slide swit-

ches 1-5 (S0) according to the signal

choice list. The signal tone for the

second signal level is adjusted with the

slide switches 6-10 (S1).

The volume is set by the slide switches

11 and 12 (see table).

The shift from the first to the second

signal level in case of devices direct

tension is realized by additional appli-

cation of a positive operation voltage

on clamp 3. In case of alternating ten-

sion the shift is made by additional

application of the phase (L1) of the

operation voltage on clamp 3.

After the completion of the setting the

electrical connection to the bottom

section has to be re-established and

the upper section has to be fixed with

the respective screws on the bottom

section. (CAUTION! Don’t damage the

gap of the joint.)
