CHAPTER 4 - Maintenance/Troubleshooting
he CellStat
TM
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, 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 16 - 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: CellStat
TM
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
CellStat
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.
CELLULAR PREPAID ACCOUNT:
CellStat
TM
uses prepaid cellular service
from either Cingular or T-Mobile. The remaining balance in the prepaid account can be
determined by querying the dialer with the *00 Report System Status command. The
dialer will speak the current cellular signal power level as weak, normal, strong, or none;
as well as the remaining balance, in dollars, in the cellular prepaid account.
Alternatively, this information can be queried from the dialer by sending a “Stat” SMS
text message from your mobile phone to CellStat
TM
’s cellular phone number. CellStat
TM
will respond by sending an SMS text message of current status back to your phone.
If the prepaid balance ever falls below $5, the dialer will begin placing calls to all the
telephone numbers to report this as an alarm condition. On the upper left-hand side of
the dialer enclosure, near the cellular antenna, is a label that indicates the cellular carrier
and phone number of the dialer (See Figure 3 in CHAPTER 2 -- Installation). When it is
time to replenish/top-up the prepaid cellular account, these two pieces of information are
all that is necessary. There are several options for adding minutes to the account: you
can purchase Prepaid Wireless Phone cards at retail stores, from some ATM machines
