IMPORTANT! BUMP TEST THE MONITOR

Prior to use, every gas detection monitor should be bump tested to confirm the response of all sensors and activation of all alarms by exposing the monitor to a concentration of target gas that exceeds the low alarm set point. A bump test is also recommended if the monitor has been subjected to physical impact, liquid immersion, an Over Limit alarm event, or custody changes, or anytime the monitor’s performance is in doubt.

To ensure greatest accuracy and safety, only bump test and calibrate in a fresh air environment.

The monitor should be calibrated every time it does not pass a bump test, but no less frequently than every six months, depending on use and exposure to gas and contamination, and its operational mode.

•Calibration intervals and bump test procedures may vary due to national legislation.

•Honeywell recommends using calibration gas cylinders containing the gas that is appropriate to the sensor you are using, and in the correct concentration.

General

The BW RigRat Local Area Gas Monitor (hereinafter called “RigRat”) as a transportable equipment, fills the gap between portable personal detectors and fixed-infrastructure fire and gas systems. Its primary function is to alert personnel of a gas leak in their proximity, it can provide continuous measurement of gas concentrations.

The RigRat’s main use is in temporary zone monitoring, such as repair, fence line, and inert applications where there is a possibility of a gas release.

The overall dimensions of the RigRat are about 396mm x 288mm x 470mm (15.6” x 11.4” x 18.5”), it consists of an enclosure, 2 rechargeable battery packs (P/N 500-0165-000) as main power, 1 Li-ion rechargeable cell (P/N MS-621T) for RTC power, 1 LCD display, 4 LED indicators for light alarm, 2 buzzers for the audible alarm, 1 multi-function button, and printed circuit-board assemblies. In addition, it may also be optionally equipped with a gas-intake pump, up to 6 kinds of wireless modules in 4 wireless module slots, and up to 5 kinds of sensors in 6 sensor slots.

An AC charger connector is provided to charge battery packs in a non-hazardous area. Refer to “Specific Conditions of Use” for more information. An IS charger connector is used to connect through a safety barrier to charge one of the battery packs in hazardous areas, likewise providing the intrinsically safe power to the product.

The RigRat is transportable and does not require grounding (earthing). However, the circuits and the metal parts of the enclosure can still withstand a 500V dielectric test with a leakage current no more than 5mA.
