Determining The Number Of Transmitters; Recommended Installation Height - Honeywell IAQPoint2 Guide De Démarrage Rapide

Determining the Number of Transmitters

The number of transmitters required is determined by a unit's operational
surveillance radius. Using the table below, the number of units required
can be easily evaluated.

Comb Most combustibles are heavier than air, with the exception of
methane, hydrogen, ethylene and acetylene. For gases that are
heavier than air, sensors should be installed approximately 30 cm
(1 ft) from the floor. For combustibles that are lighter that air,
sensors should be installed 30 cm (1 ft) from the ceiling, close to
the potential leak source.
*May differ in certain applications: Hot NO
