The NV 2 TC keeps the Te-
lecontrol devices TC, TC EIB
and TC Alarm as well as the
designs for mounting on a
DIN-rail (TCR and TCR Alarm)
functioning during a power fai-
lure (see chart on page 6).
The buffering time is reduced
with activated outputs and
depends mainly on the relays
being used.
With the installation of a se-
cond accumulator, the buffe-
ring time doubles.
A power failure will be noti-
fied after approximately 15
minutes by a switching output
(NA). This message can be
passed on from the TC to the
telecommunication system, if
required.
It is also possible to draw up
to 500 mA current from the
NV 2 TC (for instance: exter-
nal alarm sensors). However,
the current being used for
feeding external sensors will
reduce the buffering time for
the TC.
To lock the NV 2 TC-housing,
you can exchange the catch
with a safety lock, available
under the article number 690
324.
Together with the safety lock
a micro switch is delivered
to mount on the upper head
piece of the housing (picture
2,B). The switch can be inte-
grated in a sabotage line of
an alarm system or if desired
to one of the alarm inputs of
the TC.
