1 INTRODUCTION
The Parasense 3300RM2 monitor is an advanced refrigerant leak detection device. Utilising infrared
absorption sensors, the 3300RM2 automatically collects and analyses samples of air to report and
record the time, presence and concentration of refrigerant, in accordance with the system
configuration.
The monitor has 8 individual SAMMs (sampling channels), each having their own pump and filter.
Each SAMM is connected to the location to be sampled by semi-rigid nylon pipework, referred to as
freeway. The specific location can then be further subdivided into small regions using a manifold and
multiple sampling pipes known as spur kits (refer to the Installation Guide within this manual).
Each SAMM on the 3300RM2 can be used to monitor refrigerant gas in one of two ways. Option 1 is
to configure the 3300RM2 to monitor the overall area where refrigerant equipment is contained. This
ensures the level of refrigerant concentration is kept within specified limits. Option 2 is to configure
the 3300RM2 to monitor a specific piece of refrigeration equipment, directly targeting the source of
any refrigerant leaks.
Alarms can be generated at three different levels described as ‘Alert’, ‘Alarm’ and ‘Critical’. These
alarms can be signalled to other devices using the 16 configurable relays. The current alarm status is
indicated on the 169mm (6.5”) TFT LCD display.
