Eagle Eye Battery Room 

Venting System 115V AC 

Executive Summary 

Eagle Eye's hydrogen gas detector and forced ventilation fan system designed for use in 

battery charging rooms and other areas where Hydrogen may be present. The system 

consists of a minimum of two parts, a hydrogen gas detector with relay contacts that 

mounts in the highest part of the room and a large vent fan enclosure mounted through 

the outside wall.  The system is NFPA compliant.  The system has four fans factory rated 

at 850 CFM each.  This conforms to N+ 1 for 2550 CFM.  The vent is equipped with a 

Positive Airflow Shut Off.  These doors can be closed by an external electrical command.  

They will stop any airflow from passing through the fans.  Available power options are 

110 V AC, 24 V DC, or minus 48 V direct current.  It is fused at 10 amps for -48v.  The 

vents can be daisy chained, more than one vent can be controlled by one gas detector.  

More than one hydrogen gas detector can activate a vent. The unit usually is set up to 

exhaust air but can be factory configured to source forced air into a room. These units 

are designed with flexibility in mind.
