Mounted Gas Monitor
||The SBG-200 is an affordable solid-state completely self-contained monitor capable of
detecting a variety of toxic and flammable gases and vapors. Several sensors are available
which allow it to be calibrated to alarm at gas concentrations well below their lower
explosive limit or OSHA ceiling.
|The monitor provides its own visual and audible alarms as well as meter
indication of gas concentrations. Contacts are provided to allow it to connect to a
central alarm system or to turn on emergency apparatus.
The SBG-200 is easy: plugs into a 110v outlet - no installation is necessary, one switch
controls all user functions, and it can be wall mounted for permanent installation or
moved from area to area as required.
Controls & Indicators
The high quality taut band meter provides a continuous indication of the concentration
of hazardous gas in the area. The meter is divided into three separate zones of safety.
The meter is intended to register concentration levels relative to the calibration point
requested. The red zone indicates concentrations of gas or vapor above the danger level.
The units alarm and calibration point is set to occur at the border of the red and
the yellow zones. When the needle enters the yellow or caution zone, the SBG-200 is
sensing gas or vapor concentrations within 20% of the calibration alarm point.
Light and Sound Alarms
When the SBG-200 senses gas concentrations at or above, the calibration point as
represented by the red zone on the meter, the red alarm light will flash and a high
frequency sound alarm built into the top of the unit will sound. The sound alarm emits a
pulsating shriek. In order to reduce false alarms, it has a built in 12 second time delay
after an alarm condition exists. If during this 12 second period the gas concentration
falls below the critical level, the unit will not alarm.
Three Position Control Switch
The black control switch on the front of the unit allows control of three separate
Stand-By: This function (the switch in
its bottom position) allows the user to monitor the atmosphere as indicated by the meter,
but cuts off all audible and visible alarms as well as the relay. Stand-by should be used
when the unit is being stabilized to prevent false alarms. Stand-by can also be helpful
when checking the calibration of the unit or when cleaning up a hazardous condition which
is already known to exist.
Sensing: This middle position is the
normal switch position when the unit is in full operation.
Reset: This top position is a momentary
setting which will automatically move back to the sensing position. The reset position is
required to turn off the alarms and to restore the relay to its normal setting. Without
manually moving the switch into reset, the alarm functions (if they are set for latching)
will remain latched in the event they should go on.
The SBG-200 comes with a high reliability relay circuit which can be used to connect
the monitor to a central alarm system, turn on a remote alarm, or turn on a small
emergency device. The relay connection is located on the bottom of the unit. This relay
does not provide power, but instead acts as a switch to turn on something which is already
powered. This switch is rated to withstand power up to 1.0 amps at 120 volts AC. A mating
connector is also provided which can be used to attach the relay to wires running from the
The SBG-200 uses a solid state high reliability sensor which is located either on the
bottom portion of the unit enclosed in the black housing or at the end of the optional
sensor extension. Under most conditions your sensor is sufficiently protected from dust
and other contaminants. It should give you trouble free service for many years. Several
sensors are available. When monitoring particularly hazardous or corrosive environments or
locate the sensor at an alternate point, the SBG-200 is available on an optional basis
with the sensor mounted on a cable which can be extended from the monitor up to a distance
of 100 feet depending upon the application. The sensor operates by diffusion. It is very
stable over time.
A green power light on the front of the unit indicates that the unit is functioning
when it is lighted.
The SBG-200 is provided with rubber feet so that it can be conveniently moved from
location to location. Screw slots are provided on the back for permanent wall mounting.
