1.1.2 Battery Powered
The DoorGard LS2/LS2P system is battery powered;
when the system is not in use, it consumes very little
power, but the batteries normally discharge over an
extended period. The DoorGard LS2/LS2P system
powers itself down (sleep mode) after one of the fol-
lowing events:
• fifteen seconds after the last keypress that does
not result in an unlock
• immediately after sending the lock pulse regard-
less of what triggered it (valid PIN, REX input,
Toggle/Passage code, etc..)
• fifteen seconds after a Lockout code is entered
• immediately after a Toggle/Passage ON/OFF code
is entered
1.1.2.A Low Voltage Operation
The LS2/LS2P has two low voltage indicators, the Low
Voltage Warning and Low Voltage Inhibit. The system
wakes up momentarily every 30 seconds and checks
the battery voltage to determine if the voltage is low.
When either of these situations arises the battery
should be changed.
