one 9-volt alkaline battery (supplied) which can
power the unit for at least one year. If the battery
voltage drops below normal, a low-battery report
will be sent to the receiver with any status or

indicated, replace battery.
NOTE: Temperature and humidity extremes may
reduce the life of the battery.

mounting to the mounting plate unless a battery is
installed in the battery compartment.
