Network Communications Board

The Master Alarm and Area Alarm are stand-alone units unless the optional
Network Communications Board is installed in the Area Alarm. In that case; you
can browse, download, configure, and troubleshoot Master Alarms and Area
Alarms with a personal computer that is connected to the facility's Ethernet. The
alarm's Web pages are built-in; no setup is required.
NOTE:
The Area Alarm Module High and Low setpoints which can be configured only
by using their front panels.
When an alarm condition occurs, each Master Alarm can send electronic mes-
sages to up to five users. In addition, the entire MedPlus TotalAlert® Alarm
Network can be remotely monitored over the Internet.

System Power Supply

Each rough-in assembly or back box assembly for the original version of the
MedPlus TotalAlert® Alarm Network has its own power supply, which is
installed at the factory.
The power supply for the MedPlus TotalAlert® Alarm Network Conversion Kits
is a single sub-assembly that is installed in an existing rough-in box.
Each power supply converts the facility's 120 V AC 60 Hz power to 20 V AC to
operate the alarm. This unit contains the main power switch, transformer, main
fuse, and terminal block.
NOTE:
The Local Alarm is not available as a conversion kit.

Transducers

Each transducer is factory-programmed for the specific type of gas or vacuum
shown on its housing. Transducers convert the gas or vacuum pressure into a dig-
ital signal, then they send that signal to the corresponding Area Alarm Module. If
the transducers are not connected to the appropriate gas-specific Area Alarm
Module, an error message (A07) displays on the Area Alarm Module. The trans-
ducers are connected to Area Alarm Modules with stranded, twisted-pair, shield-
ed cable (two shielded wires). To ensure dependable operation, the cable should
not be greater than 4500' (1372 m) in length.
Transducers are housed in protective enclosures to reduce the risk of tampering
and to allow proper operation in a variety of environments. The enclosure is
transparent to allow the observation of an on-board troubleshooting LED. The
