Dialer is built to require minimal maintenance. Only the system
battery requires your attention from time to time for your dialer to continue
performing with no problems.
INTERNAL RECHARGEABLE BATTERY : A battery in typical standby use
will last approximately 2 to 4 years. Battery life is mostly dependent upon the number of
power outages sustained and the age of the battery, and temperature. A new battery
should take no longer than 72 hours to gain full charge, capable of powering the system
through a power outage of greater than 24 hours. Battery backup time may vary
depending upon the age of the battery and the frequency and duration of alarm callouts
which occur while the dialer is operating on the standby battery.
FUSE: DialStat

features an internal, resettable fuse which never requires service. If
you can measure 12 – 20 VDC at the external power input terminal block, but the AC
POWER/CHARGING LED is OFF, the fuse may have blown. Remove power from
DialStat
TM
by turning OFF the Power switch and unplugging the removable External
Power Terminal Block. Wait for about a minute for the fuse internal to the dialer to cool
down, then plug the power back in. If the AC POWER/CHARGING LED comes ON
briefly then goes OFF, the fuse is blowing. Blown fuses can be indicative of other
problems. Measure the input power supply, and verify that it is 12 – 20 VDC. A high
external voltage may cause the fuse to blow. If the fuse continues to blow and the
external power is within specifications call the factory.
