Detailed Component Descriptions

Chapter 1: Introduction

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
manner in which the LED flashes indicates whether the transducer is
functioning properly. Refer to chapter 2 for troubleshooting procedures.

Each housing is clearly labeled and color-coded for the type of gas or vacuum
being monitored. DISS, gas-specific, demand flow valves are used with all
transducers. The demand flow valves permit replacement of transducers
without shutting off the gas or vacuum pipeline.

The maximum input pressure for transducers is 200 psig (1379 kPa). The
maximum input vacuum for transducers is 30"Hg (101 kPa). All transducers
are pressure tested to NFPA 99 standards and cleaned for oxygen services.

Remote-Mount Transducers

A DISS, gas-specific, demand valve (AD) is included with each transducer
(AG) (see figure 1-16 on page 1-37). This demand valve (AD) attaches to a ¼"
National Pipe Thread (NPT) female connection in the pipeline outside of the
rough-in box assembly.

Figure 1-16. Remote-Mount Transducers

The remote-mount transducer can be used with either the original MedPlus
TotalAlert™ Alarm Network or the conversion kits.
