Low Battery Indication: An illuminated Yellow LED indicates an abnormally low battery condition.
This may be due to low battery voltage or a missing battery. When this happens the Red warning
LED will flash, the audible beep will sound, and the remote indicator will be enabled. When the user
is alerted to the warning status, the illuminated condition of the Yellow LED and the lighted condition
of all the Green module LEDs denotes a battery fault and not a TVSS module power or fuse fault.
The Disable Battery switch should then be pressed to silence the audible alarm beep, flashing
LED, and remote warning for the battery malfunction. The Yellow LED may remain illuminated as a
reminder that the battery needs replacing. This action re-enables the warning function to continue to
monitor TVSS faults. When the battery is replaced, the Disable Battery switch should be momentarily
pressed. A fresh battery, when the disable battery switch is pressed, will cause the Yellow LED to turn
OFF and will re-enable the Low Battery warning function after pressing the battery disable switch.
Battery Replacement: Press battery holder and slide battery out. Be sure to follow the battery
polarity marking on the battery compartment.
Test Switch: A "Press to Test Switch" enables the user to test for proper operation of all the functions
described above. When the test switch is held down, the following functions will occur:
• The Yellow low battery LED will illuminate.
• The Red warning LED will flash.
• The audible tone beeper will sound.
• The Remote Supervisor Panel warning indicator (an accessory item), if wired in, will be activated,
thus also testing the Remote Supervisor Panel.
