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.
