transponder that will be able to start the ACD units and all exhaust fans and
blowers when the vehicle is energized or started. The transponder shall keep the
systems running for as long as the vehicles are running and shall restart the
systems when the Vehicles return to station. The transponder must plugin to
standerd power plug or USB plug that is supplied by truck Mfg. Transponder that
have to be wire in to electric system of truck will be rejected.
Functionality - The system shall have the ability to monitor/control multiple
System Blowers and alarming functions:
Source capture fan control (EF-1) for Future - The purpose of EF-1 is to
ventilate vehicle exhaust gasses to atmosphere, drawn directly from the vehicle
exhaust pipe, via a source capture hose. Each vehicle shall have a radio
transmitter in it which will activate when the vehicle is started. Upon sensing the
vehicle being started, this blower will activate. The blower will operate
continuously while the vehicle is running and for an adjustable number of minutes
after the vehicle is turned off or leaves the vicinity (500' radius) of the control box.
The adjustment will be via a potentiometer on the circuit board and shall be 1 to 5
minutes. There shall also be an elapsed time meter, located on the circuit board,
which will log the runtime (in hours) of the EF-1 blower unit only. This meter shall
be 4 digits (up to 9999 hours) and resettable via a small pushbutton located next
to the meter/display.
The receiver, located inside the control enclosure, shall be powered by 24VAC.
There will be two wires from the receiver to our circuit board which signals the
receiver has picked up an input from a vehicle transmitter.
There shall be a set of "Remote Start" terminal blocks on the circuit board which
allows EF-1 to be started by a remote dry contact from any outside source. This
functionality shall only be active while EF-1 in is in AUTO mode and will start
when the remote signal is received and will stop immediately upon losing this
signal.
There shall also be an LED on the circuit board indicating when the blower is
running.
There shall be one temperature sensor located inside the source capture work
system, which will be hardwired back to the control box. The intent of this sensor
is to monitor the temperature of the exhaust gasses passing through the
hose/ductwork. The maximum gas temperature will be recorded on a meter
located on the circuit board and is resettable via a small pushbutton located next
to the display.
Operators on the control for EF-1 shall include a button which toggles through
OFF/AUTO/ON and an indicator which indicates the blower is running.
General ventilation Fan Control (EF-2) - A second "through the wall" Exhaust
Fan shall draw air/heat/humidity from within the facility to atmosphere. The
purpose of this blower is threefold. First it will run whenever a signal from a radio
transmitter, located in any vehicle, is present. The adjustable time-out period,
however, will be independent of EF-1 and EF-3 and will be via another
potentiometer on the circuit board. The range of this time-out is 5 to 30 minutes.
This blower shall also be started by a dry contact input which will be provided by
a thermostat. The intent is if it gets too hot in the building, the thermostat will
activate EF-2 to draw the hot/humid air out of the building to meet Code. This
blower will stop immediately upon seeing the signal from the thermostat open.
The third function is to draw exhaust gasses out of the building, as detected by
CO/NO2 sensors (see below). When a "low level" or "danger level" of exhaust
gasses are detected, this blower will activate and continue to run for an
adjustable number of minutes after the signal is removed. This range shall be
the same 5 to 30 minutes described above.
There shall also be an elapsed time meter, located on the circuit board, which will
log the runtime (in hours) of the EF-2 blower unit only. This meter will be 4 digits
(up to 9999 hours) and resettable via a small pushbutton located next to the
meter/display.
There will be a set of "Remote Start" terminal blocks on the circuit board which
allows EF-2 to be started by a remote dry contact from any outside source. This
functionality will only be active while EF-2 in is in AUTO mode and will start when
the remote signal is received and will stop immediately upon losing this signal.
There shall also be an LED indicator on the circuit board to signal when the
blower is running.
Operators on the control for EF-2 will include a button which toggles through
OFF/AUTO/ON and an indicator which indicates the blower is running.
Air Cleaning Device Fan Control (EF-3) - The third blower(s) will be Air
Cleaning Devices or filter units, mounted in bays or living area, which will
circulate and filter/condition the air within the facility. There can be as many ACD
units as the desires, but all will be controlled by one RUN signal from the circuit
board.
The purpose of this unit is to filter and/or cool the air within the facility. This
blower shall run whenever a signal from a radio transmitter, located in any
vehicle, is present. The adjustable time-out period, however, shall be
independent of EF-1 and EF-2 and will be yet another potentiometer on the
circuit board (for a total of 3). The range of this time-out is also 1 to 30 minutes.
There shall also be an elapsed time meter, located on the circuit board, which will
log the runtime (in hours) of the EF-3 filter units only. This meter will be 4 digits
(up to 9999 hours) and resettable via a small pushbutton located next to the
meter/display..
Control wiring for this blower shall require a 4 conductor cable which is a 24VAC
"RUN" signal coming from the circuit board and two wires for a "Filter Dirty" signal
going back to the circuit board. Both these signals shall be wired in parallel with
like signals from filter unit to filter unit. Power wiring for the filter will come into
the ACD Unit, through the contactor and then to the blower motor. The purpose
of the dirty filter signal is to illuminate an indicator light on the control panel. It
will not affect the functionality of the filter unit and all pressure switches will be
wired in parallel. The purpose of this indicator is to alert the operator to inspect
each filter unit for a dirty filter condition.
There shall be a set of "Remote Start" terminal blocks on the circuit board which
allows EF-3 to be started by a remote dry contact from any outside source. This
functionality will only be active while EF-3 in is in AUTO mode and will start when
the remote signal is received and will stop immediately upon losing this signal.
There shall also be an LED indicator on the circuit board to signal when the
blower should be running.
Operators on the control panel for EF-3 will include a button which toggles
through OFF/AUTO/ON and an indicator which indicates the blower is running.
In addition, there shall be a Filter Start button that will start the filter units and it
will run for the time period set with the potentiometer. The Filter Start button will
only be functional when the OFF/AUTO/ON button is in the AUTO mode.
Gas Monitoring (CO/NO2) - Separate gas monitoring devices shall be hardwired
into the circuit board for the purpose of activating only EF-2 (as described above)
and to activate the yellow and/or red beacons and the alarm horn. The signals
for the beacons and alarm horn will be a relay closure from the gas sensors,
therefore a constant input, but the indicator lights and alarm horn on the stack
light will flash/sound. The email/text alarm system will sent a message to the
monitors for this signal.
Operation of the beacon (Stack Light) - A yellow light shall flash if a low level
of toxic gas is detected. A red light shall flash and alarm horn will Sound if a high
level of toxic gas is detected.
Power Loss Indication - A battery backup system shall be incorporated into the
control box which shall cause an alarm horn to activate. This will happen
whenever a power loss is detected. The power loss alarm shall operate for a
minimum of 10 minutes after losing power. The email/text alarm system will sent
a message to the monitors for this signal.
Fire/Smoke detection — the controller shall have a fire / smoke detector to turn
off the blowers in the event of a station fire. This shall meet NFPA /Florida fire
code. The fire detector will also send an email/text alarm message to the
monitors for this signal.
High Temperature - The controller shall have thermostat that will read room
temperature and start exhaust fans for cooling. The thermostat will also send an
email/text alarm message to the monitors for this signal if the Temp goes over a
set point.
Exhaust Fan Flow — The controller shall have an airflow sensor that will read the
airflow movement of the exhaust fan and if airflow is not detected an email/text
alarm message will be sent to the monitors for this signal.
Auxiliary Function - The controller shall be shipped with a key -fob transmitter
with 4 function buttons. Button 1 will be used to active blowers EF-1 through EF-
3. The 2-4 buttons can be used as an auxiliary function and will activate dry
contact relays located inside the control box. These relays can be used for many
auxiliary functions, such as overhead door operation or traffic light activation, for
example.
Exhaust Fans and Make Up Air — The stations shall have or be provided with
an exhaust fan(s) and make air that will provide a minimum of 2 cfm per square
foot of garage area. This exhaust fans must be tied to the CO/NO2 toxic gas
detectors.
Installation of System — The installation and mounting of the system must be in
accordance to all mechanical and electrical building codes. The hanging of ACD
units shall not interfere with fire equipment, sprinklers, garage doors, or HVAC
systems. The hanging of ACD units must be by steel strut or concrete anchors
which are approved by building code department or pre-engineered by approved
Florida certified public engineer in design.
Warranty — Warranty shall be (5) years on all equipment and labor.
