ISACC Instruction Manual
LITHIUM BATTERY
The lithium battery provides backup to the RAM and to the real-time clock, it's function is to
retain the time and programming if the power fails and backup battery is exhausted. On the
circuit board, the lithium battery is located under the acrylic safety panel on the right side. To
activate the battery, pull the paper strip out of the battery clip. The lithium battery is a
CR2430, 3 Volts, 270 mAhr. It will provide battery backup for approximately 2 years. Note:
The lithium battery will not keep ISACC operational.
TURNING ISACC ON
Now that ISACC has power, the ON-OFF switch may be turned on. The ON-OFF switch is
located on the right side of the circuit board below the power supply terminal block. ISACC’s
buzzer will sound briefly. The “power” LED will come on and be constant and the “pulse”
LED will blink steadily. The “phone” LED will not be lit.
When the unit is turned off, it is disabled. Programming parameters are retained by the 3V
lithium battery. In the off position, the 3V lithium battery is in use, however 18V battery
backup is not.
RESET BUTTON
Under the acrylic safety panel on ISACC’s PC board is a reset button. This is provided to
manually reset the unit. The button can be pressed by pushing a pen or thin object through
the hole provided. When the reset button is pressed, the PC board stays powered, but the
system is reset. None of the unit's programming will be affected by resetting the unit. Any-
thing that ISACC recognizes as an alarm will be acknowledged and all dial out processes will
be halted.
BUZZER
Located on the PC board is a buzzer. When ISACC is turned on or reset, this buzzer will go
on briefly and then go off. The buzzer may also be used as a local audible alarm. It is consid-
ered OUTPUT9 in the programming of the parameters and the C program.
PHONE LINE INSTALLATION
ISACC must be hooked up to an analog phone line so that it can dial out for an alarm. On
the PC Board there is an RJ11C phone jack. It is located at one end of the PC BOARD and
is labeled PHONE (board location P3) . Connect ISACC to a standard 2 wire phone line.
ISACC dials using pulse or tone, with loop start only. ISACC will recognize ringer frequen-
cies from 16 to 60 Hz.
IMPORTANT: Never install telephone wiring during a lightning storm. Never install
telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch uninsulated telephone wires or terminals unless the telephone line has been
disconnected at the network interface. Use caution when installing or modifying tele-
phone lines.
