INTRODUCTION
There exist a variety of causes for cooking fires, but
most causes involve unattended cooking. Here are
some tips to help prevent a cooking fire in your
kitchen.
FIRE PREVENTION TIPS:
•Never leave the kitchen when cooking food.
•Use fresh cooking oil whenever possible. The
ignition temperature of used cooking oil can be
lower than normal and it may contain left-over
solids which can ignite.
•Smoke generated from cooking oil is an indication
that the temperature of the oil has exceeded the
desired cooking temperature of 350-375 F. As the
oil temperature increases, the smoke produced
will increase significantly. If this occurs, simply
turn the burner down or turn it off to prevent the oil
from reaching its ignition temperature.
•Be sure to keep the cooking surface and
surrounding counter areas clean and clear of
combustible materials which could ignite.
•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 FIRE:
NEVER attempt to move a burning cooking vessel
after it has ignited. Any movement could splash
burning grease and spread the fire or cause severe
injury. NEVER TRY TO EXTINGUISH A GREASE
FIRE USING WATER. Evacuate the kitchen and call
the Fire Department immediately, then alert others
and evacuate the building. Let your Guardian G600-B
extinguish any range top fire. Because of the heat and
smoke associated with a cooking fire, it is
recommended that you wait at least 30 minutes after
the fire has been extinguished before re-entering the
building and approaching your kitchen range.
OPERATION:
The Guardian G600-B system is an automatic fire
suppression system designed to detect and extinguish
cooking fires on residential type range tops. In the
event of a stovetop fire, the sensors will activate at a
pre-set temperature and signal the main CPU board.
The main CPU automatically sends a signal to release
the extinguisher valve assembly, releasing the
extinguishing agent and simultaneously activates the
CPU-mounted alarm, and the fuel shutoff which
disconnects the gas and/or electricity to the range.
APPLICATION AND LIMITATION
•The Guardian G600-B is designed and Listed for the
protection of 30 in. wide, gas or electric residential
range tops when installed in conjunction with a 30 inch
wide exhaust hood or microwave/exhaust hood
combination with a flat ferromagnetic underside. The
extinguishing system is intended for installation within a
kitchen cabinet having an internal height of 12" or taller
and located either directly above, or adjacent to the
range top and exhaust hood.
•Guardian G600-B System is acceptable for use with
either a ductless or ducted exhaust hood.
•The extinguisher enclosure assembly is intended for
installation within a protected space, such as a kitchen
cabinet as outlined in this manual.
•Only components identified by part numbers in this
manual are authorized for use with the Guardian G600-
B system unless expressly stated in this manual.
•All electrical wiring and alarm connections are to be in
compliance with the National Electrical Code (NFPA
70), National Fire Alarm Code (NFPA 72) and any
applicable state or local municipal codes.
RESIDENTIAL RANGE-TOP USE ONLY
•The Guardian G600-B extinguishing system is designed
and thoroughly tested in accordance with UL Subject
300A for normal residential type cooking applications
which originate from residential range top cooking
appliances when used in conjunction with a flat faced
(bottom) exhaust hood or microwave hood only.
•The Guardian G600-B extinguishing system is not
intended for the protection of commercial "restaurant-
style" cooking equipment.
•The maximum range top cooking surface protected by
the Guardian G600-B System is 720 square inches
measuring 30" wide and 24" deep.
•The Guardian G600-B is not designed or intended for
the protection of areas adjacent to, or within the
residential range top, such as nearby counter tops or
within the range oven.

FEATURES AND OPERATION OF THE G600-B CPU (P/N G602)
There are several modes of operation. Reset/Power-
On Mode, Diagnostic Test Mode, Fire Detect Mode,
Shut-Off Sequence, and Alarm Sequence. Several
sequences of events occur during each mode as
listed below.
1. Reset/Power-on
Power-on from inserting the battery or a reset
resulting from pressing the reset button cause the
same action. Immediately upon reset, the CPU board
performs 6 tests before entering Fire Detect Mode. If
any of these tests fail, the result is a slowly flashing
red indicator. If the main unit passes all 6 tests upon
reset, the result is a display of the green indictor for 2
seconds, whereupon it enters Fire Detect Mode and
the system is armed.
2. Diagnostic Test
Pressing the test button will enter the CPU into a
diagnostic test mode. Press and release; do not hold
down. The same tests that are performed at reset are
performed during the diagnostic test mode. These
are, in the order they occur, check sensor 1, check
sensor 2, check battery, check solenoid, check for low
pressure(if so equipped), check for pull-pin presence
in the pull pin socket(see Figure 3). Upon failing any

particular test, a sequence of audible chirps will sound
which represent a failure code (as well as a quick
flash of the red indicator). If multiple tests fail then you
will hear multiple series of beeps with a pause
between each to identify multiple failure codes.
Diagnostic failure codes identify which of the six tests
failed (see “Diagnostic Failure Codes”). The CPU will
then revert to a slowly flashing red indication if the
test failed. If all 6 tests pass, the unit will enter a
Shutoff Sequence. This provides a way to verify that
the entire system is working properly and the Fuel
Shutoff function can occur in normal operation. See a
further explanation of the Shutoff Sequence in
Section 4.
Note: Pressing the Reset button or the Test button
should not result in solenoid activation with resultant
suppressant dump. Be sure to always place the pull
pin in the handle when servicing to prevent any
accidental discharge of the system.
Diagnostic Failure Codes
One chirp - Sensor 1/Remote Pull
Two chirps - Sensor 2
Three chirps - Battery Voltage
Four chirps - Solenoid
Five chirps - Low Pressure
Six chirps - Pull-pin
3. Fire Detect Mode
During fire-detect mode, the main unit monitors the
two sensors to detect high temperature indicating a
fire. If a fire is indicated, the CPU will issue an Alarm
Sequence (See Section 5. “Alarm Sequence”). During
Fire Detect Mode the CPU will continue to silently run
all six diagnostic tests. If at any time one of these
tests fails (with the exception of the low battery test
explained below), the CPU will immediately issue a
Shutoff Sequence to prevent use of the cooking
appliance until the fire suppression system is
serviced. The only exception to this rule is a delay in
issuing the Shutoff Sequence if the diagnostic failure
is a low battery.
Approximately once per minute the battery is
checked. If it is low there will be a short chirp to
indicate that the battery needs to be replaced. The
unit will continue to function normally, with the
warning beep occurring approximately every minute
for about 4 ½ hours. If the battery is not replaced
before the 4 ½ hours has expired, the system will
initiate a Shutoff Sequence. If a reset is initiated in
this situation, the CPU will not resume normal
operation, as it cannot pass the reset or diagnostic
tests.
4. Shutoff Sequence
A shutoff sequence will cause an audible alarm for 10
seconds, and will disconnect fuel to the cooking
appliance. Following the ten seconds of audible alert,
the unit will issue a chirp about every minute to alert
the owner that the fire suppression system needs to
be serviced.
There are six things which will result in a shutoff
sequence. These are: (1) Low battery indication has
persisted for about 4 ½ hours. (2) A test sequence
was executed successfully. (3) The pull-pin was
removed from its socket during Fire Detect Mode. (4)
An open circuit was detected on one of the sensors
during Fire Detect Mode. (5) An open circuit was
detected on the solenoid during Fire Detect Mode. (6)
If cylinder pressure monitor indicates pressure is low.
5. Alarm Sequence
An alarm sequence will only occur if a low voltage is
detected at one or both of the sensors. This is an
indication of very high temperatures or of a short
across the sensor circuit. This sequence can only
occur when the CPU is running in Fire Detect Mode.
A short circuit across the sensors at power-up or
during a test sequence will result in a test failure
which prevents the unit from entering Fire Detect
Mode.
The alarm sequence causes an audible alarm,
suppressant to be released and the fuel shutoff to
disconnect fuel to the cooking appliance. This cycle
will continue until the unit is reset or the battery is
depleted.

DETECTION SENSOR ASSEMBLY (P/N G605)
The sensor assembly, which is temperature activated, consists of two sensors mounted in a high temperature silicone
rubber sleeve. The rubber sleeve contains magnets running along its length that allow for easy installation on the
front edge of the underside of the hood or microwave-hood. The detection sensor assembly (p/n G605) is to be
installed where normal ambient cooking temperatures do not exceed 300 deg. F (148.8 deg. C).
The distribution assembly consists of one housing and
cover with a stainless steel braided hose coming out of it.
The stainless steel braided hose has a quick connect fitting
installed on the end for easy connection to the valve head
of the extinguisher. Inside the housing there are 2 nozzles
mounted in fittings connected by a stainless steel tube.
The assembly is installed underneath the hood against the
wall. The Nozzles angle shall be adjusted based on the
distribution assembly’s height above the cooking surface.
The nozzles/hose assembly can be removed and reinstalled
with the hose coming out the opposite side of the housing
depending on installation requirements.
Note:
The stainless steel braided hose with quick
connect shall be on the same side of the
distribution assembly as the system
enclosure, i.e., if the hose is on the left side
of the distribution assembly, enclosure shall
be mounted inside the cabinetry above the
microwave hood / range hood on the far left
side or vice versa for the right side.

Phillips #2 Screwdriver Safety Goggles
INSTALLATION INSTRUCTIONS
Before beginning the installation of your Guardian
G600-B unit, locate and identify each part. (See
FIGURE 1) Turn off the circuit breaker to the kitchen
range hood and stove before boring holes. Wear
approved safety goggles. Protect stove top and counter
surface from falling debris.
Note:
Installation is not considered complete until “Arming the
System” is performed as outlined on page 15.
Perform the following:
1. Assemble all suggested tools. Remove all
components from the box and familiarize yourself
with assembly components.
2. Review assembly procedures and check physical
height and width requirements of cabinet above or
beside vent hood. Also check minimum and
maximum height requirements for nozzles and
sensors. (See FIGURE 5)
3. Plan your installation by selecting the desired
location of the Guardian G600-B System Enclosure
/ Extinguisher Assembly. The Guardian G600-B is
usually on the left side of the cabinet directly above
the hood or microwave hood, however; right side
mounting or side cabinet installation is an option.)
(See Figure 6)
4. Determine the best route from below the hood to
the location of the Extinguisher Assembly. Before
Drilling, measure the route and make certain that
the sensor cable and stainless steel braided hose
are long enough to connect to the Guardian G600-
B System Enclosure / Extinguisher Assembly in its
desired location. The stainless steel braided hose,
sensor wire and interconnect cable can route
through the same set of holes.
5. Using your electric drill and 1” hole saw, drill any
holes required for your planned route avoiding
damage to any existing wires, plumbing, etc. that
may be along the chosen route. Clean up any
dust/debris made while drilling.
6. Carefully remove the main CPU housing from the
Guardian G600-B System Enclosure / Extinguisher
Assembly by loosening the thumb screw and
removing the front cover of the enclosure -set
cover to the side (See FIGURE 2). Using your #2
Phillips driver, loosen the three silver screws in the
teardrop slots inside the main CPU housing. Two
are on the left side (top and bottom) and one on the
right side (top). Once they are loose the main CPU
housing can be removed by sliding the housing
slightly up and then away from the cylinder- set
CPU housing to the side.
(See Figure 2)
7. Place the Guardian G600-B System Enclosure /
Extinguisher Assembly in its desired location and
fasten the base with two screws installed through
the two holes located on the front corners at the
base of the housing. (See Figure 6)

8. Attach the Sensor Assembly to the bottom of the
Hood/Microwave Hood by placing it near the front
edge and allowing the inline magnets to secure it in
place. It should be installed between 12 and 17
inches away from the rear wall, and as far away
from the wall as the hood will allow within the
specified range (See Figure 5). Make sure the
bottom of the hood is cleaned of all grease before
installing the sensor assembly. After installing the
sensor assembly along the front, the remaining
portion of the tube should run along the bottom
side of the hood towards the wall. Next, proceed to
feed the sensor wire through the route you planned
in steps 3-4. (See Figure 7)
9. If you are not using the Wireless Tx/Rx, then now is
the best time to run the interconnect cable from the
location of the fuel shut-off up to the cabinet where
the main CPU will be located. You may choose to
run the interconnect cable through a wall mount
conduit or raceway to the bottom of the cabinets
and then follow the same route as the sensor wire,
or you may choose to route it through the wall and
up to the cabinet.
10. The distribution assembly must be centered above
the cooking appliance when it is installed. Firmly
mount the distribution housing in the corner formed
by the back wall and the hood. This is done by
using two self-tapping screws to anchor into the
hood above and two 1-1/4” screws to secure to the
wall behind. Screws in the wall must be located
where they will go into the walls studs or into a wall
anchor. Screws going into the hood must be
located where they will not damage any part of the
hood including wiring, electronic components, etc.
A total of four screws must be installed. After the
housing is mounted, place the Nozzle/Hose
assembly in the housing with the hose on the same
side as your planned route. Slide the 2 clamps onto
the mounting posts in the hosing. Center the
Nozzle assembly and then secure it into place
using the 11/32” Nut Driver to gently tighten the two
clamp nuts onto the stainless steel pipe.
(See Figure 5, 7, 8 and 9)
11. Route the stainless steel braided hose through the
route planned in steps 3 and 4. You may need to
place a piece of tape over the end of the quick
coupling to prevent debris from entering the hose
as you pull it through the route. Once the hose is
pulled into the cabinet, route it through the housing
and connect it to the cylinder using the quick
coupling located under the handle.
(See Figure 6)
12. Reinstall the main CPU enclosure back onto the Guardian G600-B System Enclosure / Extinguisher Assembly
and tighten the three screws loosened in step 6. Route and connect the sensor wires, solenoid wire and
pressure gauge wire to the main CPU. (See Figure 2 and 3) Note: sensor 1 and sensor 2 plugs are
interchangeable and can be plugged into either connector.
13. Attach the green ground wire to an earth ground by using a self-tapping screw and fastening it to a grounded
metal part of the hood. (See Figure 2)

AIMING THE SPRAY NOZZLES
14. Determine the height between the top of the
cooking surface and the top of the distribution
assembly housing. It must be between 16 inches
and 27 inches.
(See FIGURE 5)
15. Loosen the two clamp nuts using the 11/32” Nut
Driver. Loosen the clamps just enough to be able
to adjust the nozzles, but leave enough pressure
that the nozzles will stay in the position you rotate
them too. Make certain that the nozzle
assembly does not slide left or right in the
housing during adjustment or the housing
cover will not fit properly. The Nozzle
Assembly must be centered in the housing
for proper fit of the housing cover over the
nozzles.
16. Using the Nozzle Aiming Gauge provided, adjust
the nozzles to the correct angle based on the
height determined in step 14. This is done by
placing the Gauge in the housing and aligning the
nozzles spray hole with the corresponding
height/angle on the Gauge. Once in the correct
position tighten the clamp nuts to secure the
Nozzles in place (See Figure 9 & 10. The
example in Figure 9 is set to 23 inches or 45.9
degrees.)
17. Place the gauge back in the housing to make
sure the nozzles are still at the correct angle; that
they did not shift during the tightening process.
18. Mount the cover on the Distribution Housing by
sliding the bottom of the cover into the housing
below the nozzles and then rotating the cover up
over the nozzles. Carefully install 4 self-tapping
screws through the top of the cover and into the
pre-drilled holes of the housing.

ELECTRIC SHUTOFF (P/N G319)
The electric stove is shut off during system activation by two methods. One of the following interface
options is used with the electric shutoff. (1)- Using the interconnect cable (standard) from the Main CPU
Control board to the electric shutoff completes a hardwired signal which in turn activates the shutoff unit.
(2)- When using the Wireless Transmitter / Receiver (optional), the shutoff, by way of the Wireless
Receiver, continuously monitors for a “Signal” sent from the Main CPU board through the Wireless
Transmitter. In the event of system activation, the Wireless Receiver responds to the signal and activates
the shutoff. Both methods cause all electrical power to the stove to shut off. The dry contacts provided on
the Guardian G600-B CPU are never to be wired directly to the cooking appliance to facilitate appliance
shut-down. Either an electric shutoff (P/N G319) or gas shutoff (P/N G316-A) shall be used.
In the event that the electric shutoff is activated or an interruption in power occurs, it must be reset. (See
“Reset Stove”, p.12)
INSTALLATION
NOTE: Ensure the Electric Shutoff is installed
within the same room as the Main CPU control
board (part #G602) for proper unit operation.
1. Turn” OFF” electricity to the range.
2. Identify your electric plug configuration; 3-prong,
4-prong or hardwire. (See FIGURES 11A, 11B,
and 11C).
3. Remove the stove power cord from the wall
outlet and plug it into the outlet on the electric
shutoff unit (See FIGURE 14).
4. Insert the stove shutoff power cord into the wall
outlet.
5. Plug the “Interconnect Cable” into the shutoff.
6. Install Interconnect cable between electric
shutoff and Main CPU. (See FIGURE 13)
7. Plug the interconnect cable into the correct
position on the main CPU. (See FIGURE 3)
8. Turn “ON” electricity to range.

WIRELESS ELECTRIC SHUTOFF
Description :
To convert the electric shutoff to a wireless
version, the standard interconnect cable is
replaced with the Wireless Tx/Rx Assembly.
The interconnect socket on the shutoff is
compatible with both the interconnect cable and
the Wireless Tx/Rx. Either interconnect option is
available and can plug into the electric shutoff.
In some cases a wireless version of the shutoff
device may be required. If this is the case, the
Wireless Tx/Rx Assembly is required to shut off
the stove. (See FIGURE 24 and 25)
Reset Stove
1. The electric stove shutoff unit may be reset by
locating the circuit breaker supplying power to the
stove and turning it off and then back on, or
2. Momentarily unplugging the shutoff from the wall
outlet and plugging it back in.
NOTE: Method two (2) requires the stove circuit
breaker to be in the “ON” position. Method one
(1) is preferable since the stove does not need to
be moved.

GAS SHUTOFF (P/N G316-A)
The Gas Shutoff Assembly G316-A is the shutoff
supplied with the Guardian G600-B system when
protecting a gas stove. Features provided with this
shutoff include the following:
1. It is designed with a “Fail Safe Mode” consisting
of a Normally Closed (N/C) valve that is
energized continually. Loss of power or
activation due to a fire will close the valve,
shutting off “gas flow” and “electrical power” to
the stove.
2. The standard Interconnect Cable will be
provided or an optional “Wireless
Transmitter/Receiver” is available upon request.
3. An extra set of dry contacts for switching
external devices during system activation are
provided via the optional Interface Enclosure
Assembly (P/N G317-A)
4. The shutoff also has a manual “power reset”
feature to eliminate any possibility of an
automatic reset/activation of the valve occurring
after a fire or loss of power.
INSTALLATION OF GAS STOVE SHUTOFF
NOTE:
•Gas stove shutoff must be installed within
the same room as the central processing
unit control board (Part #G602) for proper
unit operation.
•Turn “OFF” electric power and gas to the
stove prior to installation.
VALVE INSTALLATION
It is suggested that a licensed plumber familiar with
local and state codes install the gas valve (P/N #
G316-1) on the incoming service line to the stove.
Adhere to manufacturers installation and maintenance
instructions.
Wiring must comply with local and national electrical
codes.
The solenoid valve is designed for a continuous duty
cycle. When the solenoid valve is energized for a
long period, the enclosure becomes hot and can be
touched by hand only for an instant. This is a safe
operating temperature.
Normally, the valve is installed between the gas lines
manual shutoff and the flexible service line from the
stove. Be sure that the manual valve is closed prior to
installation of valve. (See FIGURE 15)
NOTE: The gas valve has an "in" and "out"
orientation. The Installer must make certain that
the valve is installed correctly.
Install the “Gas Shutoff Control Box” before relocating
the stove back for regular cooking conditions.
GAS SHUTOFF CONTROL BOX
INSTALLATION
1. Locate required tools and hardware for
installation.
2. If stove is not unplugged, remove the plug from
the outlet.
3. Determine the optimal location either behind the
stove or in an adjoining cabinet for installation of
the Gas Shutoff Control Box (Part # G316-2).
(See FIGURE 16) Consider accessibility to
activate the manual reset. From the Gas Shutoff
Control Box route the cables to gas valve and
power cord to wall outlet.
NOTE: Check the length of cables for
adequate length prior to installation of the Gas
Shutoff Control Box.

GAS SHUTOFF CONTROL BOX
INSTALLATION (Continued)
See FIGURE 17 for the following steps:
4. Plug the valve into the connector on the Gas
Shutoff Control Box.
5. Connect the interconnect cable or Optional
Wireless Receiver Board into the Gas Shutoff
Control Box.
6. If Interconnect Cable is used, route the cable
from Gas Shutoff Control Box to the Main CPU
board. Plug the interconnect cable into the
“SHUT-OFF” connector of the Main CPU board.
(See FIGURE 3 page 5)
7. Plug the power cord from the stove into the Gas
Shutoff Control Box and then the power cord for
the Gas Shutoff Box into the wall outlet.
WIRELESS GAS SHUTOFF
Description :
To convert the standard shutoff to a wireless
version, the standard interconnect cable is
replaced with the Wireless Tx/Rx Assembly.
The interconnect socket on the shutoff is
compatible with both the interconnect cable and
the Wireless Tx/Rx. Either interconnect option is
available and can plug into the gas shutoff. In
some cases a wireless version of the shutoff
device may be required. If this is the case, the
Wireless Tx/Rx Assembly is required to shut off
the stove. (See FIGURE 24 and 25)
Resetting Gas Shutoff Assembly
1. Turn power “ON” to the stove.
CAUTION: “GAS WILL BE FLOWING TO
THE STOVE WHEN PERFORMING THE NEXT
STEP”
2. The “Gas Flow” indicator light should be lit. If
not, push the “Power Reset” switch ( first ) and
then the ”Valve Reset” switch (second) to arm
the control box.
Note: In the event that the gas shutoff is
activated or an interruption in power occurs, it
must be reset.

ARMING THE SYSTEM
After completing the physical installation of the main unit, sensors, shut-off, and any optional
equipment, the following procedure is performed:
CAUTION –DO NOT REMOVE PULL-PIN FROM TANK UNTIL INSTRUCTED.
Ensure the following installation tasks have been completed:
1. Connect sensor 1 and sensor 2 to the CPU board.
2. Connect the fuel shut-off to the CPU board via the interconnect cable if this option is
used.
3. Connect wireless transmitter to the CPU board and wireless receiver to the fuel shut-off
if wireless shut-off option is used.
4. Verify that the solenoid connection is present and connected to the CPU board.
5. Connect the optional AC adapter to the CPU board if supplied.
6. Insert the 9 Volt battery into the battery holder.
With the cylinder pull-pin still installed in the agent tank, initiate a Diagnostic Test by press and
release of the diagnostic test button. The test should fail and issue 6 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 diagnostic test other than the pull pin test has failed and
the system should be troubleshot before proceeding further (See Diagnostic Failure Codes
pg.6). Once any troubleshooting has been resolved, retest until only the 6 chirp Diagnostic
Failure Code occurs.
1. Verify that the fuel shut-off is powered and is reset. (See page 12 for Electric, page 14 for Gas)
2. Next, check that the solenoid release latch is engaged (See Figure 28 p.19) and then
remove the pull pin from the agent cylinder and insert the pull pin in its socket on the CPU
board (See Figure 2 & 3 for location).
3. Push and release the reset switch. A momentary green light will indicate that all initial tests
have passed. If blinking red light results, remove the pull pin from the CPU board and
place it back in the agent cylinder and perform further diagnostic checks.
4. If the reset yielded a green light, leave the pull pin in the CPU. A final step is to turn on a
burner and momentarily push and release the diagnostic test button. If there are no failures
detected the CPU will run a Shutoff Sequence (The alarm will sound for 10 seconds and
shut off fuel to the stove followed by a beep every minute). This allows complete verification
of system function all the way to 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.
5. Reset the CPU board by pressing the Reset Button (See Figure 3) and confirm the green
indicator momentarily lights up.
6. Make sure all burners are off, then Reset the fuel shut-off (See “Reset Stove” page 12 for
electric stoves or “Resetting Gas Shutoff Assembly” page 14)
This completes the steps for "Arming the System”. The installation of the Guardian G600-B
system is now complete.

LATCH
For installations where the system will be subject to
vibration, there is an alternate Model G600B-C cam
activated system available.
The System is the same as the G600-B Solenoid Model
with the following exceptions:
•The G600B-C uses a trip motor with cam for activation
instead of a solenoid. (See Figure 19)
•The G600B-C cannot be installed with the optional
Wireless Rx/Tx. The Interconnect cable (P/N G622)
must be used.
•The G600B-C System uses the G602-C Main CPU
board. This version of the Main CPU board includes a
“Motor Test/Advance” Button and includes a “TRIP
MOTOR” connection on the board instead of a
“VALVE” connection. (See Figure 26)
Note: Test the Trip Motor and Cam Monthly by removing
the pull pin from the Main CPU and placing it in the handle.
Press the “Motor Test / Advance Button” and allow the cam
to make one full revolution, stopping the advancement of
the Cam just before making contact with the Latch. (See
Figure 19) After testing, return the pull pin back into the
pull pin socket on the Main CPU board and press the
“Reset” button. The green indicator should momentarily
illuminate to indicate the system is “Armed”.
