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.

- Page 1 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.
- Page 2 The fan unit is compliant with the NFPA Standard 90A Section 4.2.3, 4.2.3.1, 4.2.3.1.2, 4.2.3.2.2, and 4.2.3.3 All the active component parts on the Eagle Eye Fan Battery Room Exhaust Fan With Positive Airflow Shut Off System that are subject to testing are certified by the Underwriters’ Laboratory as follows.
- Page 3 Features of the Eagle Eye Hydrogen Gas Detector Should the concentration of hydrogen gas in the air surrounding the sensor reach 1% by volume (10,000 ppm), the "1% Caution" yellow LED will light and the 1% internal relay will close. Should the hydrogen gas concentration reach 2% by volume (20,000 ppm), the "2% Warning"...
- Page 4 H2 Battery Room Forced Ventilator with Positive Airflow Shut Off If the room were to experience the release of hydrogen gas, the hydrogen gas detector would turn on the fans when the atmosphere reached 1% hydrogen. It would sound the alarm at 2% hydrogen.
- Page 5 In operating mode If a thermal event occurs and proceeds into a conflagration, we want the fans off and the Positive Airflow Shut Off closed. This will prevent the air passage through the fan from acting as a chimney and drawing oxygen rich fresh air into the burning room.

Page 6: Installation
When the Positive Airflow Shut Off is activated by the firefighter pulling the Emergency Fan Stop switch, air pressure from the fans, and gravity, and a spring, will act to close the positive shut off doors and keep them closed. A red LED at the junction box will come on. - Page 7 The damper- jack is affixed to the outside wall with normal fasteners by others. It measures 24 inches square and needs an outside clearance of 30 inches. A one inch flange is provided to attach the unit and is in addition the listed dimensions. There are two different styles of wall jack available.
- Page 8 If the unit is an Exhaust Fan the louvers must be turned to let air out. If the unit is a Supply Fan the louvers must be turned to let air into the room. It can be positioned either way. So, the installer must understand the airflow direction. Fan Units come from the factory with the fans mounted in the direction needed for proper airflow.
- Page 9 Electrical Installation Test After the system is powered up it should be tested. Push the test button on the first hydrogen gas detector. The system will perform a self-diagnostic, and then turn on the yellow LED. At this time, the fans should also activate and the fan operation detect relay, if installed, will close.
- Page 10 Eagle Eye. Also note this hydrogen gas detector will not false alarm on smoke or carbon monoxide. It tests for hydrogen only. Test the positive shut down control. The doors will be shipped in the closed position.
