I. PATIENT SAFETY, WARNINGS, CAUTIONS AND NOTES
The CROSSVENT-3+ ventilator is intended for use only by a qualified practitioner, under the direction of a
qualified physician. All personnel operating the ventilator must be completely familiar with the warnings
and operating procedures in this manual prior to using the CROSSVENT-3+ with patients. As with any life
support device, the patients on the CROSSVENT-3+ should be visually monitored by competent personnel
at all times since life threatening conditions may arise that may not be detected by the alarms. It is essential
to test all life-support devices for proper function prior to each use on patients.
A- WARNINGS, CAUTIONS, AND NOTES
The following terms are used throughout this manual:
WARNING - Indicates a procedure or condition that could cause bodily injury.
CAUTION - Signifies a procedure or condition that could damage the equipment.
NOTE - Refers to a procedure or condition that requires special attention.
WARNINGS
WARNINGSWARNINGS
WARNINGS
• Whenever the CROSSVENT is connected to a patient, a skilled operator should be present at all
times at the ventilator or within hearing range of the ventilator’s alarm system.
• Only qualified medical personnel should operate the ventilator.
• Do not attempt to ventilate a patient until thoroughly familiar with all of the operating instructions.
• The operating instructions are not intended as recommended clinical protocols.
• Always test the ventilator prior to each use. After set up, ventilate a test lung to verify proper
operation prior to connecting the ventilator to a patient.
• If a malfunction should occur, the unit should be removed from use and repaired prior to using it
again on patients.
• Whenever an alarm condition exists it should be rectified immediately. Never allow ventilation with
an alarm condition for an extended length of time.
• High oxygen concentrations may be hazardous to the patient.
• If the gas supply fails or there is a total electrical power failure, the patient may breathe
atmospheric gas through the failsafe valve. This is, however, only a temporary emergency measure,
which requires elevated inspiratory effort and it should be corrected immediately.
• If breathing through the negative pressure relief valve or in the case of entrainment usage, the
operation of the Crossvent in a contaminated environment can be hazardous.
• Always operate the CROSSVENT on battery prior to use to confirm that the battery is functioning.
• In the event of an AC power failure, the CROSSVENT will automatically switch to battery
operation and sound an alarm. The audible alarm may be silenced by pressing the POWER
SOURCE key which will be flashing. On a fully charged battery, there will be approximately 6
hours of autonomous operation. No further alarm will be sounded until the battery is low. The
low battery alarm may be temporarily silenced by pressing the Alarm Quiet key. It is imperative to
restore AC power at this time to assure continued safe operation of the ventilator.
• A patient filter should always be used in the patient breathing circuit to prevent cross
contamination.

• Extreme care should be taken to assure that the patient circuit components are connected
correctly. Improper connection can cause malfunction.
• Periodically the CROSSVENT-3+ should be operated in the test mode to ascertain that it is
functioning properly. A test lung should be ventilated prior to each use to further insure that all
modes are functioning correctly. An external spirometer should be used to verify correct volumes
and flow rates.
• The patient should never be left unattended after the ALARM QUIET key is depressed since this is
followed by a period when the audible alarms are deactivated.
• An audible alarm always indicates an anomalous state which should always be rectified.
• While some alarms may be turned off to permit use of the CROSSVENT without them, it is
recommended that they be used at all times.
• Always be certain that the Maximum Pressure Limit is set correctly and is operative even when
volume limiting, to prevent possible inadvertent administration of high pressure. Increased
pressure can be caused by blocked tubes, changes in patient compliance or resistance, or system
malfunction.
• The alarm ports on the front of the CROSSVENT should never be obstructed.
• For proper operation only the O2sensor supplied by Bio-Med Devices may be used.
• Never operate the CROSSVENT-3+ without a battery since it will fail to operate if the plug-in
power supply is removed.
• The screened ports on the side, back, and bottom of the unit should not be obstructed when the
ventilator is in use.
• Only qualified, trained, service technicians should attempt repairs and service when needed.
Serious personal injury and/or equipment damage can result if repairs are performed by unqualified
personnel
• It is imperative to verify that clinically appropriate alarm limits are fully operational following
connection of the ventilator to a patient.
• It is important to note that once a sensor has been turned off, the alarms for that sensor are
inoperative.
• Breathing through the negative pressure relief valve requires a greatly increased work of breathing
and only air is provided. A situation in which the patient is breathing through this valve should be
rectified immediately in order to prevent possible adverse affects to the patient.
• It is extremely important that the Pressure Trigger control be carefully adjusted to assure proper
operation in the CPAP mode.
• When in SIMV, it is important to always set a correct SIMV RATE, TIDAL VOLUME and FLOW
to insure proper ventilation in case the patient becomes apneic.
• When in CPAP, it is important to always set a correct BACKUP RATE, TIDAL VOLUME and
FLOW to insure proper ventilation in case the patient becomes apneic.
• To obtain the full 3-minute duration of the Power Failure alarm, the Crossvent must have been
powered on for at least 1 minute.
• All safety measures must be observed when servicing this device. In particular, the ventilator must
be turned off and the power supply disconnected.
• Bio-Med Devices cannot be held responsible for any failure to adhere to the recommendations set
forth in this manual.

• Because this is a CE marked device, it must never be modified without prior expressed written
consent from Bio-Med Devices.
• When setting Pressure Trigger, auto-triggering or missed breaths may occur due to various
conditions including, but not limited to, compliance, resistance, rate, flow, PEEP, I:E ratio, and
circuit characteristics.
• Do not re-use disposable breathing circuits.
• Operation of the Crossvent in a contaminated environment can be hazardous when entrainment is
used.
• It is extremely important that the Pressure Trigger control be carefully adjusted to assure proper
operation in the SIMV and CPAP modes. Also, under certain conditions in SIMV with PEEP,
even though the low peak pressure alarm is set correctly for assisted breaths, there may be no low
peak pressure alarm following a patient disconnect until the next assisted breath. This period may
be up to 2 minutes.
• Improper changes made in the Calibration menu can be detrimental to the performance of the
ventilator.
• Do not apply tension to the flow sensor (pneumotach) tubing. Do not allow the sensor to be in the
patient circuit when not connected to the ventilator.
• In rare instances, when using the Crossvent with an air/oxygen blender, there may be a reduction in
the delivered flow at the higher flow settings. This reduction may occur when the blender is set
below 30% or above 90% O2and the Crossvent is set to flows above 80 lpm. Lower supply
pressures to the blender will tend to decrease the flow further so be sure these supply pressures are
maintained at 45- 75 PSI (310-517 kPa). If the Crossvent has the exhaled tidal volume monitoring
feature, it is recommended this be used to ensure proper tidal volumes are being delivered. If it
does not have this feature, then an external spirometer is recommended.

CAUTIONS
CAUTIONSCAUTIONS
CAUTIONS
• Clean, dry, medical grade gas sources supplied at 31 to 75 psi (303.6 – 517.4 kPa) unrestricted flow
must be used at all times to assure proper operation of the CROSSVENT Ventilator. If an
air/oxygen blender is used, then 45 – 75 PSI (310 – 517 kPa) should be supplied to the blender.
• The CROSSVENT should not be steam or gas sterilized as this will result in damage to some of its
components.
• Connect the oxygen sensor (optional) upstream of the humidifier since the fuel cell functions better
in non-humidified gas.
• Touchscreen control keys should be pressed by hand only. Care should be taken not to allow keys
to be contacted by sharp objects as damage may result.
• Clean touchscreen only with alcohol. Clean the rest of the CROSSVENT unit with mild, non-
abrasive, anti-bacterial cleanser.
• Do not place liquids on or near the CROSSVENT. Liquid entering the unit can cause severe
damage and malfunction.
• It is recommended that the CROSSVENT never be left with its battery discharged as this will
reduce battery life. After discharge of the battery, recharge fully before disconnecting the plug-in
power supply.
• Only replace the battery pack with Bio-Med Devices part #PRT4467. Do not substitute. The cells
are non-standard high capacity.
• When using an AC power source, only the power supply provided with the Crossvent is approved
for use with this ventilator. Any other power supply may cause damage and/or unreliable
operation (see Appendix F).
• Any more comprehensive DC power supply than that which is supplied must be short circuit
protected and must comply with all of the specifications and standards as listed in Section III, Part
B.
• Do not use in a MRI room.
• Antistatic or electrically conductive hoses or tubing should not be used.
• When it is necessary to operate the Crossvent from an AC inverter, only inverters in compliance
with NEMA standards should be used (see Appendix F).
• Prior to turning the unit on for the first time, the battery must be charged fully using the included
power supply.
• Do not apply tension to the flow sensor tubing. Do not allow the sensor to be in the patient circuit
but not connected to the ventilator when ventilating.
• Do not allow the temperature of the battery to go above 131° F (55° C) whether the unit is on or
off as this may cause damage resulting in a shorter life expectancy of the battery.

• With entrainment on, flow accuracy from 5 - 100 lpm is ±10% or 1 lpm, whichever is greater, and
with a flow of 100 lpm and over, flow accuracy is within 15% of displayed flow. No accuracy is
claimed below 5 lpm.
• When the CROSSVENT is turned on, it automatically recalls all of the settings stored in memory
before it was turned off. The parameters stored are: all the main functions; high and low alarm
limits; secondary modes; which sensors are on or off. Several factors can cause the battery backed
memory to be lost. These are: low battery backed memory battery voltage (service required);
defective random access memory (service required); or if the microprocessor is, by chance, storing
data in the battery backed memory at the time power is turned off. In this case it is necessary to
re-enter the previously set parameters.
• The Maximum Pressure should always be set higher than PEEP in order to achieve the PEEP
setting.
• While connected to an active gas source, the Maximum Pressure and PEEP controls should be
turned off (fully counter clockwise) when the Crossvent is not in use to conserve gas.
• The Power Failure alarm may not be silenced using the Alarm Quiet key. The Power Failure alarm
may be silenced by pressing the alarm reset button.
• Pressure Support is only active during SIMV and CPAP, but may be set at any time.
• The wall plug-in power supply is furnished for 117 VAC, 60 Hz or 220 VAC, 50 Hz operation, as
required. It is not possible to overcharge the battery. Always keep the battery fully charged when
not in use.
• It is important to use the correct reference gases (100 and 21%) when performing the Oxygen
sensor calibration. A worn out sensor will not calibrate accurately.
• Since it is not possible to damage the CROSSVENT ventilator by normal use of its keys and
control knobs, the user is encouraged to experiment with the CROSSVENT settings while the unit
is not connected to a patient.
• A highlighted field on the display indicates that a parameter has been selected and may be adjusted
using the arrow keys.
• If it is desired to deactivate the oxygen sensor, select it and scroll the lower limit down to OFF.
The oxygen function is now inoperative. The function may be reactivated at any time by pressing
it and scrolling the low limit up. The oxygen sensor is now reactivated. This allows the ventilator
to be used without the oxygen sensor. When this sensor is off, it may be disconnected while the
ventilator is in use, without causing an alarm.
• For blended gas, the Bio-Med Devices blender should be used.
• It is recommended that an external filter/water trap be used at all times in order to provide greater
protection to the internal components of the CROSSVENT.
• For greatest accuracy, verify flow using a 60% O2 gas supply, making certain that the pressure to
the CROSSVENT inlet remains within specified pressure limits (31-75 psi; 303.6 –517.4 kPa) at all
flows.
• When the Crossvent is first turned on and is in battery mode, if a period longer then 60 seconds
passes and the BATTERY key has not been pushed, an audible alarm will sound. When the
BATTERY key is pushed, the audible alarm will be silenced.
• Due to the fact that O2 sensors sometimes change output over time once exposed to atmosphere, a
calibration should be performed periodically (once a month) in order to assure optimal accuracy.
When the sensor is consumed and does not calibrate properly, it should be discarded and a new
sensor installed and calibrated.

• It is not recommended that entrainment be turned on or off while ventilating. However, if this
should become necessary, then it should be done during the expiratory phase of the breathing
cycle. Be aware that this will change the flow.
• Approximately twenty minutes of operation will remain after a low battery alarm assuming a
properly maintained battery in good condition.
• The battery should be replaced at least every two years. Only use batteries supplied by Bio-Med
Devices, part #PRT4467.
• Prior to disposal of any component, with particular attention to the battery and PCB, check with
your local controlling authority for disposal regulations.
• When first turned on, the unit displays “Bio-Med Devices, Inc.” until the initialization process is
complete. If this does not clear, submit unit for service.
• Be aware that the SIMV rate is also the backup rate which is the rate the patient will get in the event
of apnea.
• While scrolling a parameter, some hesitation may be observed.

UNPACKING
CAUTION: Prior to turning the unit on for the first time, the battery must be charged fully
using the included power supply.
Examine the CROSSVENT carton to ascertain whether it has sustained any damage during shipment.
Inspect the contents of the shipping carton. If any damage to the product is observed, notify the carrier at
once. Only you, the consignee, can make a claim against the carrier for damage in shipment..
Once the Crossvent and accessories have been removed from the packaging and passed visual inspection,
place the unit in a location where it will be within reach of a standard AC outlet. Plug the separate AC
power cord into the accompanying power supply and then plug this cord into the standard AC outlet. Plug
the locking connector from the power supply, red dot facing to the front of the Crossvent, into the Power
Connector on the left side of the unit just below the ON/OFF switch. Once plugged in, the charging LED
above will begin to blink slowly (approximately once per second) indicating it is charging. (Rapid blinking
indicates a problem with the charging and Technical Support should be contacted at 800-224-6633).
Charge the unit until the green charging indicator stops blinking and remains solidly lit. This indicates the
battery is fully charged. This may take up to five hours depending on the state of the battery when the unit
was received.
Refer to the performance checks in the service section of this manual prior to placing this ventilator into
service.

GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
The CROSSVENT-3+ Intensive Care/Transport Ventilator is an ultra compact, electronically controlled,
time cycled, volume or pressure limited ventilator with intensive care capabilities. It provides a wide range
of operating parameters to allow ventilatory support of patients from pediatric through adult. The
CROSSVENT-3+ delivers the same oxygen concentration as the supply gas unless the optional entrainment
is in use in which case it is a nominal 50% O2.
The ventilator’s microprocessors provide all operational functions, as well as monitoring the patient and
providing alarms. It allows the user to enter many different operational and alarm parameters to
accommodate a wide variety of clinical situations.
Airway pressure is sensed using an internal pressure transducer, and pressure is displayed as a bar graph on
the LCD. The patient inspiratory effort is also sensed using a pressure transducer. An absolute pressure
transducer monitors atmospheric pressure and automatically compensates the displayed flow for altitude
changes.
Since the CROSSVENT-3+ is totally separable from a compressor and since it may be used with any 31 to
75 psi (214 – 517 kPa) psi gas source, it is extremely versatile. It may be used in most areas of the hospital
and in transport. It may be mounted on a compressor, on a pedestal stand, a cart, a wall bracket, or a bed
rail. It may also be mounted in vehicles such as helicopters and ambulances.
CAUTION: Do not use in a MRI room.
The CROSSVENT-3+ has an internal battery which provides power during transport and in the event of an
AC power failure. If the external power should fail, the ventilator automatically switches to its internal
battery and sounds an alarm. The battery operation is approximately 6 hours on a fully charged battery. If
more time than that is required, the backlight may be turned off as described in this manual. Whenever
external power is restored, the CROSSVENT-3+ switches back to external power operation. It will charge
the battery whenever external power is available.
The CROSSVENT-3+ Ventilator’s extreme reliability is made possible by:
• An absolute minimum of moving parts.
• An extremely low total parts count.
In addition to increased patient safety, the high reliability insures low downtime and thus more economical
use.
The CROSSVENT-3+ provides a complete array of features and ventilatory modes and functions which
include:
• Microprocessors control of all operational functions and monitoring.
• A Graphic LCD (liquid crystal display) with a touchscreen keypad, allowing the clinician to select
functions just by pressing the function displayed by the LCD. This provides the friendliest and
most flexible possible user interface.
• Automatic switch-over to battery backup operation.
• Auto-test mode with complete microprocessor diagnostics.
• Sensors to measure airway pressure, oxygen concentration (optional).
• Exhaled Tidal Volume and Minute Volume displays & alarms (optional).
• Displays and alarms for Peak Pressure, Rate, Mean Pressure, PEEP Pressure and Oxygen
concentration and more.
• Programmability and expandability.
• Built-in triggered demand flow for minimum work of breathing during SIMV and CPAP and a
simplified system design.
• Integral ASSIST CONTROL, SIMV, CPAP, PEEP, and Pressure Support functions.
• Altitude Compensation
• RS-232 input for PC interface for software updates.

Adjusting this knob sets the inspiratory flow from 0 - 120 lpm. The
Flow setting is displayed in the FLOW key on the display. It is
accurate from 1 to 120 lpm.
WARNING: In rare instances, when using the
Crossvent with an air/oxygen blender, there may be a
reduction in the delivered flow at the higher flow
settings. This reduction may occur when the blender is
set below 30% or above 90% O2and the Crossvent is set
to flows above 80 lpm. Lower supply pressures to the
blender will tend to decrease the flow further so be sure
these supply pressures are maintained at 45- 75 PSI
(310-517 kPa). If the Crossvent has the exhaled
tidal volume monitoring feature, it is
recommended this be used to ensure proper tidal
volumes are being delivered. If it does not have this feature, then an external
spirometer is recommended.
NOTE: With the optional entrainment on, flow accuracy from 5 - 100 LPM is ±10% or 1 LPM, whichever
is greater, and with a flow of 100 LPM and over, flow accuracy is within 15% of displayed flow. No accuracy
is claimed below 5 LPM.
When air entrainment is on, verify the message “ENTRN” is displayed in the Inspiratory Source Key.
Set the FLOW after entrainment is turned on since the flow calibration is automatically adjusted for
entrainment. It is not recommended that entrainment be turned on or off while ventilating. However, if this
should become necessary, then it should be done during the expiratory phase of the breathing cycle. Be aware
that this will change the flow.

Male DISS 9/16-18 fitting. Clean, dry, medical grade gas, delivered at 31 to 75 psi (214 – 517 kPa) pressure
at 132 lpm is required. These requirements apply to the inlet of the ventilator in order to ensure proper
flows. If the supply pressure falls below 31 psi, an internal sensor will detect this and the Crossvent will
alarm. A serviceable 40-micron filter is contained within the supply fitting.

When using a blender, oxygen and air supplies are connected to the blender and the output of the blender is
then connected to the Crossvent Supply Inlet. For optimum performance, 45 – 75 PSI (310 – 517 kPa)
should be supplied to the blender. Oxygen concentrations set by the blender are then delivered to the
patient. Refer to the Blender Operation Manual for instruction on its use.

AINMENTAINMENT
AINMENT
When equipped with the optional Air Entrainment Module, the CROSSVENT is able to supply either 100%
or 50% (nominal) oxygen during transport, without the use of compressed air. A unique feature of the
entrainment system is the ability to deliver repeatable volumes during volume limited ventilation, with
relatively constant oxygen concentration.
When using entrainment, the source gas should be 100% O2. When the air entrainment control on the right
side of the CROSSVENT is turned to the ON position, a sophisticated, multiple venturi system is activated,
which draws in ambient air and dilutes the 100% O2 supply gas to a nominal 50% concentration.
An additional advantage of using entrainment is that the oxygen supply consumption will be reduced,
thereby increasing the operating time on a given supply of gas.
When entrainment is off, the gas delivered is the same as is connected to the supply inlet.
WARNING: Operation of the Crossvent in a contaminated environment can be
hazardous when entrainment is used.

This receptacle accepts the plug from the factory supplied, U.L. approved, power supply module. The plug
and receptacle are keyed so they will only go together when the red dot on the plug faces to the front of the
unit and the cord is within the two arms of the guard. By necessity, this power supply meets all the
specifications and standards listed in Section III, Part B. Use only Jerome Industries model WSZ116M
(16VDC, 3A) with the appropriate mating plug. The Crossvent should not be used with any other wall plug-
in or desktop AC adapter. This is used to operate the ventilator and to charge the battery whenever it is
below full charge. The wall plug-in power supply is furnished for 117 VAC, 60 Hz or 220 VAC, 50 Hz
operation, as required. It is not possible to overcharge the battery. Always keep the battery fully charged
when not in use.
CAUTION: Do NOT attempt to rotate the power connector while it is plugged into the
ventilator. It must only be pushed straight in and pulled straight out.
CAUTION: When using an AC power source, only the power supply provided with the
Crossvent is approved for use with this ventilator. Any other power supply may cause
damage and/or unreliable operation.
CAUTION: Any more comprehensive DC power supply than that which is supplied must
be short circuit protected and must comply with all of the specifications and standards as
listed in Section III, Part B.
CAUTION: When it is necessary to operate the Crossvent from an AC inverter, only
inverters in compliance with NEMA standards should be used (see Appendix F).

The Charging LED indicates the charging mode when the external power supply is plugged into the
Crossvent. Its states are:
1. Slow Blinking (approximately once per second)- unit is in rapid charge mode.
2. Rapid Blinking- failure in the charging system or the temperature of the battery was above 125°F
(40°C) when the external power supply was connected.
3. On Steady- trickle charge mode.
The battery operation is approximately 6 hours on a fully charged battery. Turning off the backlight can
extend this time (refer to Backlight in Part D of this section).
To charge the battery, only the power supply provided by Bio-Med Devices should be used. With the red
dot on the supply’s connector facing the front of the Crossvent, plug the external power supply into the side
of the unit and into an AC outlet. Charge the battery until the charging LED indicates it is in trickle charge
mode and the battery is fully charged (solid LED). The amount of time required to fully charge the battery
depends on many factors, including the state of charge when it begins. The maximum time for an exhausted
battery is approximately 5 hours. When done, verify battery power by unplugging the external power cord
from the side of the unit while it is turned on. The Crossvent should alarm and the power source key at the
bottom of the display should flash “BATT”. Press this key to cancel this alarm. The battery bar indicating
the remaining battery power should span the entire battery key unless the battery was fully discharged, in
which case it may only indicate 90%. This condition will self-correct with further charging cycles.
If the temperature of the battery is over 125°F (51°C), it cannot accept a charge. This situation should be
avoided. If the battery reaches this temperature during a rapid charge, it will go into trickle charge mode
until it is below this temperature.
CAUTION: Do not allow the temperature of the battery to go above 131° F (55° C)
whether the unit is on or off as this may cause damage resulting in a shorter life expectancy
of the battery.
When the state of the battery is determined to be within approximately 20 minutes of remaining autonomous
operation, the Alarm 3 menu will flash “LOW BATTERY, CONNECT EXTERNAL POWER” and sound
the audible alarm. The ventilator should be switched to external power or removed from service and
recharged when this alarm occurs. If the battery is allowed to expend energy to a point below 6 volts (well
below the Low Battery alarm limit), the ventilator will shut down independent of the On/Off switch. If this
occurs, the external power supply must be used to recharge the battery and the On/Off switch must be
turned to Off and then back to On before the unit will operate.
NOTE: 20 minutes of operation after the low battery alarm assumes a properly maintained battery in good
condition.
The NiMH rechargeable battery is located internally and should only be accessed by trained service
personnel. To prolong life and maintain performance, it is recommended that the Crossvent be stored with
the power supply plugged in or with the battery fully charged at a relative humidity of 65% (±20%)

whenever possible. Because NiMH batteries will naturally “self-discharge”, it is strongly recommended the
battery be cycled through at least one charge/discharge according to the table below if left off the power
supply for an extended period of time.
Storage Temperature Range Time to Charge/Discharge

32°F to 85°F (0°C to 29°C) 61 to 90 Days
WARNING: Never operate the CROSSVENT without a battery since it will fail to
operate if the plug-in power supply is removed.
CAUTION: The battery should be replaced at least every two years. Only use batteries
supplied by Bio-Med Devices, part #PRT4467. Do not substitute.

CAUTION: Do not apply tension to the flow sensor tubing. Do not allow the sensor to be
in the patient circuit but not connected to the ventilator when ventilating.
CAUTION: The pressure connection tubes of the pneumotach should always be mounted
vertically to prevent collection of condensate in the pressure tubes. The tubes should be
inspected periodically and condensate should be removed. This condensate may cause
erroneous readings and thus improper operation of the CROSSVENT. Never block these
connections with the unit operating as this can damage the internal transducer. Always
securely connect the pneumotach to its connector before inserting the pneumotach in the
flow stream. This will prevent possible damage to the internal transducer and will also
prevent humidified gas from inadvertently blowing up the pneumotach sensing lines.

Pressing this button silences the alarm of the Power Failure circuit, which is a separate section of the main
circuit board.
This circuit monitors the power to the main circuit board. If power is lost, either as a result of turning the
main power switch off or a total power failure to the circuit board, i.e., no external power and no battery, it
sounds an audible alarm (long tone) and flashes the LED, which will continue for at least 3 minutes after
failure. Pressing the Alarm Reset Switch permanently silences the audible alarm.
WARNING: To obtain the full 3-minute duration of the Power Failure alarm when
power is lost, the Crossvent must have been powered on for at least 1 minute prior
to the failure.
