7.4 Activating / Deactivating chime, siren
and test routines
The factory settings/settings after a reset of the MEVAC-4
system are as follows:
Function For
Microphones
Chime
MEVAC-1PTT and
MEVAC-4PTT
Fireman's microphones
Siren
MEVAC-1FH and
MEVAC-1FT
Test routines All speaker zones
Measurement tone

Impedance tolerance
for impedance changes in a line
*A reset will not reset a changed measurement tone level to 49 Vpp.
To change these settings:
1) Call up the selection menu and enter the password (chapter
7.1, steps 1 – 4) to call up the programming menu:
T1=NEXT T2=LEVEL
T3=INST. T4=MOD/REL

2) Use the button T1 to call up the menu for the chime.
T2 = CHIME
Fig. 91 The chime for the microphones is switched on
3) Here, the preliminary chime for the microphones can be
switched on/off with the button T2.
4) Press the button T1 again to call up the menu for the fire-
man's microphone:
T2 = F. CHIME

5) Use the button T2 to switch on or off the siren that will
sound (for 6 sec. if file supplied on the memory card is
used) when the talk button of the fireman's microphone

measurement and open-line (interruption) measurement
are to be made and to set the measuring level and the
impedance tolerance. To return from the submenus to a
higher menu level, either press the button PROGRAM or
wait for approx. 15 sec.
T2 = IMPEDANCE
Fig. 95 Here, the impedance measurement for individual zones can
be switched on and off.
Important: When attenuators are used, the respective line
must be switched off (also see chapter 4.2.4).
T2 = SHORT CIRCUIT
Abb. 96 Here, the short-circuit measurement for the individual
zones can be switched on and off.
T2 = OPEN LINE
Fig. 97 Here, the open-line (interruption) measurement for the
individual zones can be switched on and off.
T2 = + T3 = -
Fig. 98 Use the buttons T2 (+) and T3 (–) to set the level of the
measurement tone (20 Vpp – 60 Vpp). The factory setting is
49 Vpp. Always perform an installation run after making
changes!
T2 = IMP. TOLERANCE
NORMAL (07)
Fig. 99 Use the button T2 to select the desired tolerance for imped-
ance measurement: SMALL (04), NORMAL (07) and HIGH
(22) (also see chapter 4.2.2).

7.5 Resetting to the factory settings

To reset MEVAC-4 to its factory settings and to delete any
programming you may have made, proceed as follows:
ATTENTION With the reset, the entire manual programming
you may have made (with the exception of the menu lan-
guage and the measurement tone level) will be lost!
1) Switch off the unit.
2) The emergency power supply must be disconnected during
the reset. Disconnect the emergency power supply before
starting the reset.
3) Keep the buttons PROGRAM and T3 pressed at the same
time and switch on the unit again. The following display
will appear:
FACTORY RESET
Fig. 100 Reset
4) Release the two buttons.
5) Switch off MEVAC-4 again and connect the emergency
supply unit.
6) Then perform an installation run (chapter 6.1.2) so that all
components connected will be recognized again.
