Chapter 2: Installation
TURNING ISACC ON
Now that ISACC has power, the ON-OFF switch may be turned on. 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. Anything that ISACC recognizes as an alarm will be acknowledged and all
dialout 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 on the PC board to the right of the
input terminal block 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 frequencies 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 telephone lines.
