Quick Start Guide

Please read this entire manual before attempting to install and operate this gas transmitter.  
This guide is only intended to provide the basic steps necessary for installation and operation.  
Each step will reference the portion of the manual where more complete information can be 
obtained.

Step 1 – Mounting

Determine the location for mounting your transmitter(s).  The location(s) may be indicated on 
the architectural drawing.  Also, the owner or designer of the facility may be consulted.  
Mounting guidelines can be found on page 12 of this manual.

Step 2 – Input Wiring

Provide a dedicated circuit at the required 24 VAC and 6 VA at each transmitter mounting 
location.  Follow all national and local wiring codes.  The wiring should be at least 14 AWG.  A 
conductor connected to earth ground should also be provided.  The circuit must include a 
disconnect switch located within easy reach of the transmitter.

Color-coded wires exiting the transmitter housing through the top conduit connector are 
provided for connecting the operating voltage to the transmitter.  Therefore, it should not be

WARNING

This transmitter may require the use of voltage levels high enough to cause fatal injuries.  
Proper procedures must be followed any time work is performed on this unit.

Only qualified personnel should attempt to install, maintain, or service this equipment.

CAUTION

Operating this transmitter with the incorrect voltage and power requirements can cause 
internal electrical components to overheat and fail.  Operation with the wrong power 
requirement will void the manufacturer’s warranty and the installer will be responsible for any 
damage that occurs.

Contact Brasch Environmental Technologies, LLC before connecting power to the transmitter 
if you are unsure of the correct power requirement.
