Apparatus Specs Flashcards
2017 Pierce Enforcer size compared to older quantums
4 feet shorter, wheelbase is 2 feet shorter
DEF Consumption
2-3% of fuel consumption
Engine Exhaust After Treatment System
Designed to maintain itself through periodic self-cleaning called “regeneration” or “regen”
Passive Regen
Can occur during normal engine operations, driving or pumping. Requires no action by driver.
Active Regen
Apparatus may active regen without action by driver. However, when needed, driver can assist by changing the duty cycle of the engine, i.e. switch to highway driving or pump conditions or initiate a parked regen.
Exhaust temps during regen.
1500 degrees F
Solid DEF indicator light
Between 1/4 and 1/8 full
Flashing DEF indicator light
Below 1/8 full
On the 2017 Pierce Enforcer, what does the shoreline plug do?
Charges the apparatus batteries, powers the plug in the officer’s rear compartment, powers the water heater for decon use.
2017 Pierce Enforcer warm water decon system
Separate 18 gallon water tank above pump panel. 2 water heaters, 12v and 120v, designed to keep water tank warm 24/7.
Transmission Fluid Temp
Between 140 and 220 degrees F
ASR
Anti-Slip Resistance. If one wheel is off the road, spinning, ASR will apply that brake to increase torque to the other wheel allowing it to pull the apparatus out. ASR is completely automatic.
What to do when stuck in deep mud or snow, loose dirt, or sand
Press the Off Road Traction Control switch. This will allow some slippage (spinning) to assist in climbing out.
Activating on-spot chains
Engage when traveling 2-25 mph. Do not exceed 35 mph.
Front Wheel Lock
Applies air to front brakes for additional holding.
Minimum air in system to activate pump shift control lever
80 psi
2017 Pierce Enforcer priming
Air primer uses brake tanks air pressure for a venturi. No fluids or oil. Priming will start when in pump gear and shut off when primed (20 psi)
2017 Pierce Enforcer Booster Reel
150’ of 1 inch hose.
2017 Pierce Enforcer Booster Reel Friction Loss
30 gpm = 37 psi per 50’ section, 111 psi for 150’
How does regen work?
The soot build-up is removed by heating the filter until the soot oxidizes and turns into carbon dioxide gas
Brakes on an engine
Front disc brakes, rear drum brakes
RSC
Roll Stability Control. Senses when impending rollover conditions occur and, if detected, intervenes in the operation of the truck by automatically reducing the vehicle speed. RSC is automatic.
Two exceptions to pumping in pressure control mode
Drafting and Relay pumping, to avoid conflicting governor operations resulting in oscillation and pressure spikes, only the attack engine should be in pressure mode.
Disengage On-Spot Chains
Speeds of 35 mph or less (20 mph is preferred)
Rear winch capacity of brush truck
12,000 lbs
On brush truck, cut off switch will kill engine when pump pressure drops below _____
60 psi
On brush truck, name safety feature to prevent pump damage when tank runs out of water
Power cut off switch
On brush truck, what is the flow rate at 100 psi?
78 gpm
