4. NOTE When setting up multiple zones in one 4 area such as a motor room stagger these zones as they enter the IRLDS II For example if there are two motor rooms served by one IRLDS IT each motor room has three sensing zones Make the first motor room zones 1 3 and 5 and make the second motor room zones 2 4 and 6 This will allow the leak detection system to return to that area being sensed more regularly If the zone exists in a location where air flow will af fect the dispersion of refrigerant reduce the alarm lim its to a lower level than usual This will allow for dispersion of the refrigerant in the air 026 1305 Rev 4 12 APR 2010 16 General Operation 16 1 Normally each IRLDS II will sequentially perform measurements on its active zones without user input The total time it takes an IRLDS II to complete a measurement cycle is directly proportional to the number of active zones and the physical length of the air lines Monitors linked to gether on a network operate independently of each other and consequently complete their respective measurement cycles at different rates Functional Overview The IRLDS II User Interface operates by polling the network approximately once every 12 seconds to deter mine the current status of the IRLDS II monitors If more than one IRLDS II is connected to the network it will se quentially poll each monitor for its status As a practical matter this simply means that the
