Low Battery <11V
This internal line monitors the supply voltage:
if the supply voltage (between terminals [+12V] and [-]) drops below 11.3 V,
the GTCOM will transmit the ‘
Low Battery 11 Vdc
’ event code. It will transmit
the ‘
Reset Low Battery 11 V
’ event code, as soon as the supply voltage is
restored (value > di 11.3 V).
This internal line monitors the supply voltage: if the supply voltage drops below
the threshold, the GTCOM will be unable to operate.
if the supply voltage (between terminals [+12V] and [-]) drops below 9 V, the
GTCOM will transmit the ‘
Low Battery 9 Vd
c’ event code.
IMPORTANT:
If the supply voltage drops below 9 V, the GTCOM will perform
the Call cycle relative to the ‘Low Battery 9 Vdc’ internal line, and will then
switch off. To restart the GTCOM, restore the proper supply voltage (approx.
13.8 V) then press button 3.
The GTCOM will activate the ‘
Tes
t’ line periodically, in accordance with the
setting programmed in the ‘
Interval
’ and ‘
first call in
’ fields on the ‘
Telephone
’
page (refer to
Programming
/
Options

Alarm Call Cycle
If a line detects alarm status, the GTCOM will perform the Call cycle illustrated
in figure 3. If the ‘
Call all telemonitoring numbers
’ option is disabled (refer
to
Programming
/
Options
), the GTCOM will stop the call cycle after the first
successful call.
If no event codes have been programmed, or no telephone numbers have been
assigned to the internal lines, the GTCOM will not generate the call cycle.
