The 6030 holds 2 x CR123A Lithium batteries. The
estimated service life is 5 to 7 years in a typical residential
installation with the Sleep Cycle set to LG (Long),
Battery #1 (lower) is supervised for low voltage.
When
the sensor detects the voltage has reached 2.6 VDC or
less (under load), a Sensor Low Battery trouble will be
transmitted to the control/transceiver. This trouble will
be attached to all future transmissions until fresh new
batteries are installed. Battery #1 is the primary power
source for all critical functions (motion detect and radio
transmission) of the 6030 sensor.
Battery #2 (upper) is not-supervised for low voltage.
This battery is a secondary (reserve) power source for
the 6030 critical functions, but it is the primary (sole)
power source for the White Security/Convenience LED.
The White Security/Convenience LED will not operate
without a good battery installed in Battery #2 location.
We strongly recommend installing a battery in both
locations. These 2 batteries are electrically isolated in
such a way that critical functions of the 6030 can draw
power from either battery, but the White Convenience
LED can only draw power from Battery #2.
