•
Speech input level
The amplification of the speech input amplifier is adjusted by means of control P6. If set at maximum sensitivity,
the highest sound pressure level is achieved at an input level of 100 mV, where as the minimum sensitivity setting
requires a level of 1 V. The NF input has an input impedance of approx. 5 k .
•
Pitch
The pitch of the continuous tone (to be connected via terminal 4.8) may be adjusted using control P4.
•
Repetition frequency
The repetition frequency of the wailing tone (terminal 4.7) and the intermittent tone (terminal 4.5) may be adjusted by
means of control P3 in the range from 2.5 s to 200 ms ( 0.4 to 5 Hz).
EMC-Directive
The device complies with the requirements of the new EMC-directive 2004/108/EC and the low voltage directive
2006/95/EC.
The conformity with the above directives is confirmed by the CE sign.

Signalling tones
Turning on the supply voltage may activate the Varioton EV 11 signal generator, or it may be activated via a control
wire. If the signal generator is to produce only one tone, and to be turned on via the supply voltage, the corresponding
jumper in the device should bridge terminal 5.1 and the terminal corresponding to the desired tone, 4.1 “Gong” to 4.8
(“Continuous tone”).
Upon turning on the supply voltage the desired tone sounds – until the supply voltage is turned off.
If the tones are to be switched from a remote location, a suitable multi-strand control wire should be connected to the
terminals 4.1 to 5.2.
Activating a tone requires the connection of terminal 5.1 (supplies the 12 V control voltage) via a poten tial-free contact
with the corresponding selector terminal (the supply voltage of the signal generator must also be turned on).
Connect supply voltage to terminals 1.1 and 1.2. In case of DC supply voltage; please pay attention to correct polarity
(+ on terminal 1.2). Connect Protective Earth to terminal .
