P/N W03-4001-000
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.

WARNINGS
This Manual must be carefully read by all individuals who have or will have the responsibility of using,
maintaining, or servicing this product. The product will perform as designed only if it is used,
maintained, and serviced in accordance with the manufacturer’s instructions. The user should
understand how to set the correct parameters and interpret the obtained results.
CAUTION!
Only use the Honeywell-specified rechargeable lithium-ion battery pack supplied with the
instrument.
Charge the instrument Li-ion battery using the specifically supplied charger and only outside
hazardous areas. The maximum voltage from the AC charger Um must not exceed 6.0 VDC.
The battery pack can only be changed in a non-hazardous area. Only use approved
rechargeable battery pack P/N 500-0165-000 produced by Honeywell.
Any data download device connected to this instrument must be approved SELV or Class 2
equipment.
Use of non-Honeywell components will void the warranty and can compromise the safe
performance of this product.
Warning: Substitution of components may impair safe performance of this product.

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.
