NOTE
All service and maintenance on the fire suppression system
should be conducted by an authorized fire equipment
distributer. Do not tamper with fire suppression components
if not instructed to do so.
WARNING
To reduce the risk of fire, electric shock, or injury to
persons, observe the following:
•Use this product only in the manner intended by the manufacturer
(to cover domestic ranges used for domestic purposes).
•When cutting or drilling into wall or ceiling, do not damage
electrical wiring or other hidden utilities.
•Ducted exhaust fans must always be vented to the outdoors.
•Use only rigid, metal ductwork
•This unit must be properly grounded.
To reduce the risk of range top grease fire:
•Never leave the range unattended at high settings. Boil-overs
cause smoking and greasy spillovers that may ignite.
•Dense smoke from frying pans indicates cooking oil is near auto
ignition – turn the burner down or off.
•Always turn the hood fan ON when part of the cooking surface is
on
•Always make sure the hood grease filter is installed before cooking.
•Clean hood grease filter frequently. Do not allow grease to
accumulate on filter.
•Always use proper pan size. Use cookware appropriate for the size
of the surface element.
•Keep cooking areas clean and clear of combustible materials.
To reduce the risk of injury to persons in the event of a
range top grease fire, observe the following:*
• SMOTHER FLAMES with a close-fitting lid, cookie sheet, or metal
tray, then turn off the burner. BE CAREFUL TO PREVENT BURNS.
If the flames do not go out immediately, EVACUATE AND CALL
THE FIRE DEPARTMENT.
• NEVER PICK UP A FLAMING PAN. You may be burned.
• DO NOT USE WATER, including wet dishcloths or towels - violent
steam explosion will result.

de blessures aux personnes advenant un incendie de
graisse sur le dessus de la cuisinière :*
• ÉTOUFFER LES FLAMMES à l’aide d’un couvercle ajusté,
d’une plaque à biscuits ou d’un plateau en métal, puis fermer le
brûleur. S’ASSURER D’ÉVITER DES BRÛLURES. Si les flammes
ne s’éteignent pas immédiatement, ÉVACUER LES LIEUX ET
APPELER LE SERVICE D’INCENDIE.
• NE JAMAIS SAISIR UNE POÊLE EN FLAMME. Vous pourriez vous
brûler.
• NE PAS UTILISER D’EAU, ni de linges à vaisselle ni de serviettes
mouillées car il pourrait se produire une violente explosion de
vapeur.

Once hood and fan (if external) is installed and powered,
navigate into the service menu on the user interface.
Navigation instructions can be found on pages 17-19.
Press the “Balance Exhaust Fan” button, and fan will
turn on and ramp to full speed.
Once fan is on, connect one end of manometer to
plenum pressure port (1/8 inch MNPT barb located near
grease filter) and take reading. Adjust the max speed as
necessary to match the pressure with the corresponding
value on the screen (or reference the table below based
on your hood size and configuration).
For example, for a 36 inch, non-NFPA 101 compliant,
external fan – top discharge, inline fan configuration
model, to obtain the designed 300 CFM, we need the
plenum pressure reading to be 0.25 in. wc.
Fan Calibration
NOTE
Integral fan – front recirculating models shouldn’t have
to be calibrated, as these require no added ductwork.
Fan calibration is necessary for integral fan – rear
discharge and external fan configurations (both inline
and fan by others).
NOTE
To avoid poor hood performance, it is important for
the hood to be balanced for the designed CFM. For
NFPA 101 compliant models, 500 designed CFM is
required.

Operation
Unit Pre-Suppression Functions
The XRRS functions as a standard ventilation range
hood with the added capability to suppress stove top
fires.
Designed to use over a standard 30 and 36-inch
domestic range, the system relies on input from a
combination of sensors to control the fan and shutoff
power to the stove when the temperature reaches
preset points.
The fans and lights can be turned on and off using the
user interface. The range can also be unlocked via the
user interface. A password may be required to unlock
(turn on) the range and the range may be automatically
locked again after a time limit (default 2 hours) if the
hood system was configured for NFPA 101 compliance.
If the temperature reaches the cooking detection
temperature setpoint (default 115°F), the hood turns
the fan on (if not already on) and the fan speed control
buttons are disabled. The speed of the fan is no longer
controlled via the user, instead the fan is controlled via
the hood temperature.
If the temperature continues to climb, upon the
temperature reaching the high temperature setpoint
(default 180°F), the hood will immediately lock (shut off)
the range. An alarm will appear on the user interface
warning the user of the high temperature. The dry fire/
fault contacts at this point will switch state.
If the temperature continues to climb, upon reaching
approximately 216°F, the fire suppression system
will discharge, dispersing wet chemical on top of the
appliance and suppress the fire below.
NOTE
Before operating the system, system must be armed
per the instructions on page 16.
NOTE
Aiming of the hood nozzles is typically performed by
factory authorized fire equipment distributer during
startup. Do not adjust after startup and arming has
been performed.

Fire Ready Hood16
Arming the System
To arm the range, do the following:
1. Once hood and hood components are installed,
wired, and fan is balanced (if necessary), drop the
hood into the service position, (instructions on page
20) and turn on all breakers feeding the hood and
hood components.
2. Remove the black cover from the fire suppression
control board enclosure inside the hood (on left side
of hood if looking at the hood front face).
3. With the cylinder pull-pin still installed in the agent
tank (mounted beneath the fire suppression board),
and 9V battery installed on the fire suppression
control board, initiate a diagnostic test by press
and release of the “TEST” button (also on the fire
suppression board).
4. The test should fail and issue six chirps, indicating
that the pull pin has not been removed from the tank.
If the result is a lesser number of chirps followed by
the series of six chirps, then some item other than
the pull pin has failed and the system should be
troubleshot before proceeding further (see Diagnostic
Failure Codes, page 21).
5. After troubleshooting, re-test until only the 6 chirp
diagnostic failure code occurs.
6. Verify that the fuel shut-off is powered (breaker is on)
and all burners on the range are off.

Do not tamper with the fire suppression system after
the initial startup unless authorized to do so.
7. Remove wing screws that hold
the fire suppression control
board enclosure in place above
the wet chemical tank. Without
disconnecting any cables, slide
the control board assembly
towards the middle of the hood
and down so it’s next to the tank,
revealing the tank assembly.
8. Check and
make sure
the solenoid
release latch
is engaged
and holding
the release
latch up, then
remove the
pull pin from the agent cylinder and insert the pull pin
in its socket on the PCU board.
9. If the push and release of the
“RESET” button yielded a green
light, leave the pull pin in the CPU. Unlock the range
via the user interface.
10. The final step for verification is to turn on a range
burner, then momentarily push and release the
“TEST” button. If there are no failures detected, the
fire suppression board will run a shutoff sequence
(the alarm will sound for 10 seconds and shut off
fuel to the stove followed by a chirp every minute).
This allows complete verification of the system
function all the way to the fuel shut-off but without
the chemical agent dump. If the stove does not
shut-off (burner shuts off and begins to cool down),
additional troubleshooting is required.
11. Reset the CPU board by pressing the “RESET”
button and confirm the green indicator momentarily
lights up.
12. Make sure all burners are off, then unlock the range
via the user interface.
CAUTION
Carefully remove the pull pin from the tank, holding
the release latch in place, as to not accidentally cause
a fire system discharge.

Fire Prevention Tips
If you must leave the kitchen when frying food, turn the
burner off or remove the pan from the burner until you
return.
In case of a grease fire:
NEVER attempt to move a pan of cooking grease that is
already on fire from the kitchen range.
NEVER attempt to extinguish a grease fire with water.
Instead, alert the other occupants and evacuate. Let the
fire suppression system installed in the hood extinguish
the range top fire. Wait at least 30 minutes after a
cooking fire has been extinguished before approaching
your range.
