(Figure 13) A 12-volt, 12 amp-hr. sealed lead-acid
battery pack is available to allow operation of the
monitor in case of vehicle electrical system failure.
A diode is included for protection. These battery
packs are also used as a means to minimize the
required size of conductors routed up aerial ladders
and towers. This is accomplished by mounting the
battery pack near the monitor, with a small trickle-
charge conductor to the battery from the vehicle
system.
