Alarm Plus Gas Monitor is a point local area gas detector which should be mounted in proximity to a potential leak source or hazard condition The Gas Sensor is often mounted remotely from the SensAlarm Plus in an area containing a potential gas hazard such as a battery room gas bottle storage area or instrument shelter The SensAlarm Plus itself is conveniently located usually near the entrance to such an area or perhaps inside depending on the annunciation requirements and whether or not an area is normally occupied Expert consultation may be necessary to determine the most appropriate location for optimum monitoring In all circumstances the plant safety officer or other appropriate personnel should be consulted before installation Site determination at a minimum must consider the following factors Most probable location s of a hazardous gas leak Physical properties of the target gas heavier or lighter than air Air movement in the area due to HVAC or ambient conditions Operational environment vibration temperature humidity wind etc Presence of interferent gases see Sensor datasheet Access for routine preventive maintenance 2 2 Fire or other Code Compliance Issues and annunciation requirements The Uniform Fire Code and the International Fire Code both have evacuation requirements of buildings during emergency conditions These mainly concern egress safety and routes evacuation time and include emergency lighting spe
