1.4 Components
Main Circuit Board
The main circuit board contains the system’s CPU, power supply, other primary components and wiring interface connectors. The 4XTM
option module plugs in and is mounted to the main circuit board.
IPOTS-COM Communicator Card
The pre-installed IP/POTS communicator card transmits system status (alarms, troubles, AC loss, etc.) to a Central Station via the public
switched telephone network. It also allows remote programming or interrogation of the control panel using the FS-Tools Upload/Down-
load utility and a hard-wired ethernet IP connection. Any personal computer with Windows
®
7 or greater, 32 or 64 bit, and FS-Tools
software may serve as a Service Terminal. This allows download of the entire program or upload of the entire program, history file,
walktest data, current status and system voltages. See Section 6 on page 119 for more information.
The IPOTS-COM digital communicator provides the following POTS functions:
• Line Seizure: takes control of the phone lines disconnecting any premises phones
• Off/On Hook: performs on and off-hook status to the phone lines
• Listen for dial tone: 440 Hz tone typical in most networks
• Dialing the Central Station(s) number: default is Touch-Tone

, programmable to rotary
• For tone burst or touchtone type formats: discern proper Ack and Kissoff tone(s). The frequency and time duration of the tone(s)
varies with the transmission format. The control panel will adjust accordingly.
