Available in Methane (NG) or Liquefied Petroleum Gas (LPG) the AGS-iS-PSA detectors are typically used as a standalone unit or in conjunction with an AGS controller within enclosed parking garages. These units provide a clear digital display of the gas concentrations and the alarm condition housed in a robust ABS enclosure designed to withstand the parking environment. The unit comes with pre-programed alarm levels and requires no on-site set-up.
LPG is heavier than air and Methane is lighter than air. AGS recommends to mount the LPG sensor 6-18inches from ground level and above ground level. When the sensor head detects at a level exceeding 8%LEL the pre-alarm relay and 0-10v output changes state. Once the level drops the relay and 0-10v output reverts to original state. If the level continues to rise a second alarm relay set at 10%LEL will change state along with the 0-10v output. In alarm the unit provides a local audible and visual alarm.
