Figure 8: LED indicator of short circuit in any digital output
To maintain the integrity of the circuits, all outputs will be disabled for 20 seconds, including the siren
tones and audio. Even with the possibility of an electrical problem in the installation, after this time the
outputs may be activated again.
12.2 – Low Bat indicator (output 7)
There are two indications of low battery, one in the left LED the microphone (figure 11) and the other
at exit 7 of the 8 pin connector (Low-Bat). When the battery voltage decreases until the critical level
of 10.8 V ± 0.2V and is like that for 10 seconds, the LED lights up. If the battery voltage stays well for
more than 20 seconds like this, the exit 7 (Low-Bat) will be activated.
Figure 9: Low Battery LED indicator
IMPORTANT: If it becomes necessary to enable the functions of the IS2100-M G-II, even if the
battery voltage is low, the user can press any key you want, and the IS2100-M G-II will run the
function normally, except the siren tones.
After indicating low battery, the SI2100-M G-II will end this indication (led display) when the voltage
rises above 12.5 V ± 0.2V and stay there for 20 seconds. In the moment that reaches this level and
stay in this state for more than 20 seconds exit 7 is also disabled. While the output 7 is active, the exit
8 (Radio-ON) will be disabled.
Exit 7 allows the control of external devices such as alarms, relays, etc. The output current is also
limited in 250 mA.
