Outdoor Installation 

This section provides instructions on how to install the MRU in a Purcell cabinet (Flexsure® 12-2420) and perform external 
alarm connections between the unit and the enclosure. 

Note the following: 

•

 

The MRU, outdoor enclosure and required dry contact alarms cable are each ordered separately 

•

 

Additional relevant documentation - Purcell Flexsure 12-2420 installation manual provided with the cabinet 

•

 

Only trained and qualified personnel should be allowed to install, replace, or service this equipment 

•

 

The MRU connections are performed after the chassis is installed in cabinet
