Water Monitor
e medium ow Water Monitor has adjustable spray patterns and can produce 125-350GPM of water. e
monitor is adjustable from 45-90 degrees vertical and 0-320 degrees horizontal.
High speed gear ratios allow for quick response times and accurate target acquisition.
Water for the monitor can be supplied from either a re hydrant or a pumper truck. e 2.5” NHT with 30 degree
EL is located at roof level at the rear of the vehicle.
To change the nozzle pattern from straight stream to fog press the corresponding button on top of the Joystick.
To change the horizontal position right or le, move the Joystick towards the appropriate direction. To change the
vertical position up or down, move the Joystick forward for down and backwards for up. To open and close the
valve, press the trigger to open the valve and release the trigger to close the valve. e valve can be maintained
open by pressing the valve switch towards open. Note: When valve is maintained open, the trigger will not operate
the valve.
e monitor can be removed by unplugging the power control cable, pulling the quick disconnect pin, and rotating
the monitor 45 degrees counter clockwise.
Radiation Detection with External Detector
e Digital Radiation Detector consists of two parts, a Model 375 Digital Wall-Mount Monitor located in the
rear of the vehicle, with an attached 44-2 Gamma Scintillator mounted inside the vehicle at the top edge of the
passenger side windshield. A pocket Survey Meter for handheld detection is also included.
Vehicle main power must be “ON” for Model 375 Digital Wall-Mount Area Monitor to function. A Green Status
Light will be displayed when the monitor is on. If the green status light is not on, there is an additional power
switch located on the le side of the wall unit.
e Model 375 Wall Mount Detector measures the level of Gamma radiation and is calibrated in kcpm (thousand
counts per minute). When the unit is activated an audible alarm will sound and a number will be displayed
indicating the background radiation for your area. e Low Alarm is preset to 20 kcpm and is indicated by a Yellow
light and a slow beep (1 per second). e High Alarm is preset at 50 kcpm and is indicated by a Red light and a fast
beep (4 per second). If the Detector experiences an overload or instrument failure the Det Fail will be activated
and is indicated by a Red light and an audible tone greater than 68 dB.
A “Radiation Area” is equal to 2 mR/hr.
A “High Radiation Area” is equal to 100 Mr/hr.
Rem= (Roentgen Equivalent Man) Relates to the dose of radiation to the biological eect of that dose on human
tissue.
R/hr= rem per hour.
mR/hr= Millirem per hour or 1000 Rem per hour.
Cpm= (Counts per minute) the signal that indicates a radiation event has been detected.
Kcpm= (ousand counts per minute) Model 375 Digital Wall-Mount Monitor calibration.
175 kcpm= 1mR/hr.
350 kcpm= 2 mR/hr. “Radiation Area”.
