BATTERY RUN TIMES:
Each of the Fail-Safe Devices has a minimal run time depending on the load and charge of the battery.
These Devices are calculated to have a continuous battery run time of
10 to 12 minutes under full capacity
load. For example, the 10 Amp Device will run under battery power for 12 minutes under a 10 Amp
continuous load draw. Therefore, if the load draw is less than the Device’s current rating, the battery run
time will be longer. The Fail-Safe Device is designed to run the Actuator to the wired FAIL position and
hold there until Mains Power comes back ON. All of the Indelac Actuators will complete an OPEN or
CLOSE cycle in less than the 10 to 12 minutes under full load with a fully charged battery.
If longer battery run times are required, contact Indelac Controls for special order Fail-Safe Designs.
MAINTENANCE:
After proper installation, the Fail-Safe Device requires no actual maintenance. This unit should operate for
4-5 years on the original battery as long as the Mains Power is applied and the power is ON to maintain the
internal battery charger. However, we do recommend a periodic battery check to assure that the battery is
retaining a charge. This can be accomplished by using an Electrical DC Meter to measure the battery
voltage. Measure between the RED Lead of the top battery and the BLACK Lead of the other battery. This
voltage should measure between 22 to 25vdc. If this voltage is too low, try allowing the batteries to charge
with the Mains Power ON. If after this charge (usually overnight), the batteries are still low, the batteries
need to be Replaced!
