Secondary Power Source (batteries)
Observe polarity while connecting the battery. When installing one 12 volt battery for up to 7 Amp Hour applica-
tions, connect the supplied battery cable (P/N 75516) by sliding the connector attached to the long red wire onto the
positive (+) battery terminal and the connector attached to the long black wire onto the negative (-) battery terminal.
Tie-wrap or tape the two unused short wires to the long wires.
When installing two 12 volt, 7 Amp Hour batteries (in parallel) for up to 14 Amp Hour applications (60 hour
standby), follow the same procedure as described for one battery except connect the unused short wires to the second
battery. Slide the connector attached to the short red wire onto the positive (+) terminal of the second battery and the
connector attached to the short black wire onto the negative (-) battery terminal of the second battery.
When the panel is ready to have power applied, connect the battery cable plug to connector J3 on the 411UDAC main
circuit board. The battery charger is current-limited and capable of recharging sealed lead acid type batteries. The
charger shuts off when the system is in alarm. Refer to the battery calculations table to determine the correct battery
rating.
CAUTION! Battery contains sulfuric acid which can cause severe burns to the skin and eyes, and can destroy
fabrics. If contact is made with sulfuric acid, immediately flush the skin or eyes with water for 15 minutes and seek
immediate medical attention.
