In the example above we have two zones� Ground level and 1 floor level� They will be named Zone 1
and Zone 2 in the following�
Zone 1 has two entrances (DPOs) from ground level and one entrance (DPO) from Zone 2 (the transi-
tion from level 1 to ground level is also an entrance)� That is three entrances in total�
Zone 1 also has two exits (DPOs)� One exit to Main Street and one exit to Zone 2�
Zone 2 has one entrance (DPO) from Zone 1 and one exit (DPO) to Zone 1�
This information is needed when configuring the MZC (see Design and Installation Guide for Carpark
Zone Counter)�
Each DPO consists of two sensors connected to the L1 bus�
In the example below we have converted the 2 floor installation into modules� We need 6 ultrasonic
sensors and 2 loop detectors for the entrances and exits� We use loop detectors because the ultra-
sonic sensors cannot be used outside on a roof� A MZC with two power supplies are needed together
with two CPMs� The CPMs are programmed as master monitor and master monitor indicator respec-
tively�
