Fire Protection
Fire Damper
The ELXC-UVi Series Ventilator may be equipped with a combination Gaylord Fire/Balancing Damper, desig-
nated "GFBD" in the Ventilator model number. If equipped, a 250°F. thermostat will be mounted at the en-
trance of the exhaust duct collar (Refer to Figure 2-14-1). In the event of a fire and if the thermostat reaches
250°F., the following will occur:
1. The fire damper will close preventing fire from extending into the exhaust duct and fan.
2. The exhaust and supply fans will shut off.
3. The UV Lamps will shut off.
4. If the Ventilator was in a Wash Cycle it would shut off.
5. If the Command Center is wired to a building fire alarm system the alarm will activate.
6. If the Command Center is wired to a building management system it will notify of a fire condition.
7. Once the thermostat cools below 250°F., plus a 5 minute cool down, the exhaust and supply fans can
be re-started by pushing the "START FAN" on the Command Center.
Fire Extinguishing Systems
The National Fire Protection Association Standard 96 (NFPA-96) and the International Fire Code (IFC) requires
the use of a Fire Extinguishing System to cover the cooking surfaces, Ventilator exhaust plenums (the area
behind the grease extractors), and the exhaust duct (Refer to Figure 2-14-1). Upon activation of the Fire
Extinguishing System the follow will occur:
1. Fire extinguishing agent will discharge through the cooking equipment nozzles, the plenum nozzles
and the duct nozzle(s).
2. The protected cooking equipment and possibly other cooking equipment will shut off. Refer to the
above referenced codes for specific equipment that must shut off.
3. If the Fire Extinguishing System is wired to a building fire alarm system the alarm will activate.
4. If the Fire Extinguishing System is wired to a building management system it will notify of a fire condi-
tion.
5. The Fire Extinguishing System should be wired to the Gaylord Command Center. If it is, the following
will occur:
a) If the exhaust and supply fan were on the exhaust fan would stay on and the supply fan would
shut off. It the exhaust and supply fans were off, the exhaust fan would come on and the sup-
ply fan would stay off.
b) If the Ventilator Wash Cycle was on it would shut off.
c) If the Ventilator is equipped with a Gaylord Electric Balancing Damper (model GEBD) or a
Gaylord Fire/Balancing Damper (model GFBD) the damper will open.
d) If the ventilator is equipped with UV Lamps, the lamps will shut off.
6. After discharge, the Fire Extinguishing System must be recharged and certified by a fire system con-
tractor before the cooking equipment can be turned back on.
For Operation and Maintenance of the Fire Extinguishing System, refer to the system manufacture's Owner's
Manual.
Important: NFPA-96 requires inspection and certification of Fire Extinguishing Systems every 6 months.
