LED status
There are two LEDs on the CARDIO central controller printed circuit board (inside the metal box).
1) The LED in the middle of the main board is the “Status LED”.
2) The LED in the upper right corner is the “Over current LED”
1) STATUS LED
I. This LED blinks in normal operating state.
II. When it is always ON either the battery is low (no battery or empty battery) or there is no AC
POWER
When the problem is «low battery», a mesage appears in the logbook one minute after
it is detected. Should the correct code being entered when programming CARDIO a
message is sent out to the monitoring station and a pictogram appears on screen. The
LED stays ON as long as the battery is not fully recharged or replaced and that the
installer (advanced user) has not updated the status of the led. To update the status of
the Led it is necessary to enter into the programming menu and enter the installer code.
CARDIO keeps track of the «battery low» message to show that the battery jas been
discharged and needs to be checked.
When the problem is «no AC power» a message appears in the logbook and a
message is sent out to the monitoring station only 2 hours after it has been detected
and if it has not been corrected inthe meantime. However, a pictogram showing a plug
appears on screen. The LED gets back to its normal status (blinking) and the pictogram
disappears when AC power gets back.
III. When it is OFF there is no voltage either at the two power sources (AC or battery) or the power
circuit board is defective.
2) OVER CURRENT LED
I. The LED is off in normal operating state.
II. It turns ON when the total consumption needs of all devices powered by CARDIO (alarm, displays,
key readers, etc) exceeds 1A. When consumption gets down to a value under 1A this LED turns off
after a few minutes.
NOTE: CARDIO is protected by POLYSWITCH fuses (all power circuits outputs, telephone interface)
These protection circuits stand out since they automatically switch on after the problem be solved.
