SBG-200 Wall 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.

Operating Controls & Indicators

Meter
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 unit’s 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 functions.

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.

Relay Control
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 remote device.

Sensor
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.

Power Light
A green power light on the front of the unit indicates that the unit is functioning when it is lighted.

Mounting
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.
