2.1. General Placement Guidelines
NOTE:
The MGS-150 should be installed plumb and level
and securely fastened to a rigid mounting surface.
Sensors must be located within the appropriate wire lengths from the
central control unit (if used).
In all cases the sensor supplied is designed for maximum sensitivity to a
particular gas. However, in certain circumstances false alarms may be
caused by the occasional presence of sufficiently high concentrations of
other gaseous impurities. Examples of situations where such
abnormalities may arise include the following:
•
Plant room maintenance activity involving solvent or paint fumes
or refrigerant leaks.
•
Accidental gas migration in fruit ripening/storage facilities
(bananas - ethylene, apples - carbon dioxide).
•
Heavy localized exhaust fumes (carbon monoxide, dioxide,
propane) from engine-driven forklifts in confined spaces or close
to sensors.
Bacharach recommends setting the alarm delay to minimize false
alarms.
2.2. Components and Access Overview
NOTE:
The wiring is the same for the electro-chemical,
semi-conductor, and infrared models. The controller wiring is
the same for all controllers.
There is a 5-minute power-up delay to allow the sensor to stabilize.
Refer to Figure 2 and Figure 3 for internal components and wiring.
