The SST Multi-gas Standalone Toxic Gas Detector is a custom built unit which includes two high reliability microprocessor based transmitter/controller, built-in sensors, relays , audible and visual alarm in a one-piece construction. Unit can be configured with any combination of gas: combustible + toxic, or toxic + oxygen. For general purpose use. 5 Year Warranty. Made in the U.S.A.
The SST Multi-Gas Standalone Toxic Gas Detector is a completely self-contained device that measures and displays the concentration gases present in a protected area, performs local control functions, and optionally transmits this information to a central control point. Two alarm relays and a fault relay are included for each controller.
Each SST NOVA-Sensor includes a high reliability microprocessor based transmitter/ controller in the associated housing. A digital readout continuously displays operating status and the actual concentration of gas. The transmitter converts this reading to a standard 4-20 mA signal. This signal may be connected to any remote device with a standard 4-20 mA input. The HIGH and LOW alarm relays operate at user adjustable alarm trip points; either relay may be set to operate above or below the normal oxygen level. The fault relay operates upon loss of power or internal failure of the unit. Relays are suitable for controlling local HVAC or equipment shutdown.
The automatic calibration sequence is easily completed by just one person. The microprocessor stores the results of the calibration in its permanent (non-volatile) memory for use in subsequent operation. There are no screwdriver or other manual adjustments required. During the calibration process, the 4-20 mA and relay outputs from the sensor are normally suppressed. The sensor automatically returns to normal operation when the calibration is complete. During calibration, the technician may optionally activate the built-in comprehensive input/output test sequence (Comp- Test™). During CompTest, the NOVASensor’s analog and relay outputs are not suppressed, thus providing a complete operational check of the overall system.
The unit is for general purpose use only and cannot be installed in a hazardous area. However, the sensors can be remotely installed in a hazardous area.
