MEGA3 NFPA Medical Gas Notification System
4107 9016 59.03
NetBIOS Name Service
Local method of addressing a device by
name. This allows a web browser to reference
a device by name instead of an IP address,
such as 192.168.2.3.
Remote Sensors
Pressure / vacuum sensors mounted outside
of alarm panel back box. Sensor assembly
may be mounted separately or ganged to-
gether near pressure / vacuum pipelines.
Sensors must then be wired to alarm panel.
Simple Mail Transfer Protocol (SMTP)
Protocol for sending e-mail on a network.
Subnet Mask
A binary number used to separate the net-
work portion from the host portion of a
network address.
SMTP Client
Computer or device that uses SMTP to send
e-mail by communicating with an SMTP
server. The MEGA3 alarm panel acts as an
SMTP client.
SMTP Server
Computer or device that uses SMTP to receive
email from an SMTP client and then transfer
it across the internet.
Transmission Control Protocol (TCP)
Protocol used to send data streams between
two devices. TCP guarantees reliable and in
order data from sender to receiver.
User Datagram Protocol (UDP)
Protocol used to send short messages be-
tween computers. UDP does not guarantee
reliable transmission (packets may be lost,
duplicated or out of order), but is faster and
more efficient than TCP.
Ethernet Switch
A device that connects many Ethernet devices
together with optimization. Message destina-
tions are examined and passed only to the
correct device.
Firewall
A computer or computer software that pre-
vents unauthorized access to private data
from outside computer users.
Gateway
A computer or device that connects two com-
puter networks together (such as a private
network and the Internet).
General Fault Relay
Single-pole single-throw dry-contact relay
output. Used to activate remote alarm or
building management system. Relay will
open whenever ANY audible alarm on panel
is in progress. General Fault Relay will deac-
tivate only after alarm condition is corrected
and alarm panel resumes normal status.
HyperText Transfer Protocol (HTTP)
Protocol used to manage the request and
transfer of web pages to a computer.
Internet Protocol (IP) Address
Unique number that identifies a device on a
network.
LED
Light Emitting Diode
Local Sensors
Pressure / vacuum sensors mounted inside
alarm panel back box. Sensor assembly must
be piped to medical gas / vacuum pipelines.
Media Access Control (MAC) Address
A unique hardware address of a device on an
Ethernet.
Master Alarm Panel
Alarm panel that monitors medical gas and
vacuum source equipment and main pipe-
lines.
