Client One side of a 2-sided TCP socket connection. The client is the one responsible for initiating the socket connec-
tion with the remote host (the server). The console represents the client side of the socket connection with the
SG-CPM3.
Computer
Message See Automation Message.
Console A PC application program which can connect to the receiver and provide diagnostic/programming abilities to
the user. For the SG-System III, the console connects to the SG-CPM3 via TCP/IP. Visit the Tyco website
(www.tyco.com) for the latest version.
Dialer Another name for a control panel.
DNIS Dialed Number Identification Service.
DTMF Dual Tone Multiple Frequency . A method of dialing which utilizes 2 sets of 4 tones (frequencies) each.
Selecting one tone from each set will produce 16 distinct pairs. These pairs are used to dial digits when dialing
a telephone number.
Ethernet A network protocol which encompasses the lowest logical layer of the network stack, immediately above the
physical layer. This protocol is governed by the IEEE and is outlined in the IEEE802.3 specification. Ethernet
consists of several variations, including 10Base2, 10Base5, 10BaseT, 100BaseT, and others. 10BaseT and
100BaseT are the most prevalent.
Equivalent Line
Number An option in the receiver. By default printer and computer messages will contain the line card number. Some-
times it is necessary to output the printer and computer messages with a different line card number; in this case
this option can be used to overwrite the line card number in the printer and computer outputs of the receiver.
Event The specific type of alarm being reported by the panel.
Event Code A term used to describe a character or group of characters in an automation output. This character(s) is used to
represent the event that was reported by the panel. Example 1:Sur-Gard automation reports an alarm event
using an event code of 'A', Restore as 'R', or Trouble as 'T'. Example 2: Sur-Gard automation reports using a
SIA output for a burglary alarm using an event code of 'BA'.
FES Format Expert Systems . The name given to a receiver task which performs the basic functions of: 1. sending
handshakes; 2. detecting the format from the panel; 3. processing the alarm from the panel; 4. sending a kiss-
off to the panel.
Format The pre-established order of events and meanings of the various characters in an alarm transmitted from a
panel to a receiver.
FSK Frequency Shift Keying . A modulation technique used with low-speed modems (300 to 1800 bps). The car-
rier frequency is shifted between two discrete frequencies in accordance with the binary serial data.
Handshake A signal sent by the receiver to a panel indicating that a connection has been established. These are either
tones or modem data.
Heartbeat A periodic signal sent from the automation outputter tasks to the automation software to verify the presence of
that output. The period of this heartbeat is controlled via an option in the SG-CPM3. Alternatively, the heart-
beat refers to the signal sent between SG-CPM3s to verify the presence/absence of each other.
Hook Flash The process of the receiver going temporarily off-hook, usually in an attempt to transfer the phone call.
Hot-Swappable Refers to the ability to add or remove particular cards to or from the system without removing power. In the
SG-System III, the SG-CPM3, SG-DRL3, SG-DC/DC3 and SG-PSC3 are all fully hot-swappable.
