Multi-Zone Gas Monitors
P/N: 3015-5074 Rev 11 31
SECTION 4. GENERAL OPERATION
4.1. Functional Overview
Normally each MZ monitor will sequentially perform measurements on its active zones without user input.
The total time it takes a MZ monitor to complete a measurement cycle is directly proportional to the number
of active zones and the physical length of the air lines. Monitors linked together on a network operate
independently of each other and consequently complete their respective measurement cycles at different
rates.
The Remote Display operates by polling the network approximately once every 12 seconds to determine the
current status of the MZ monitors. If more than one MZ is connected to the network, it will sequentially poll
each monitor for its status. As a practical matter this simply means that the more complicated the network,
the longer it will take the RD to update the status information for all zones.
