1. FIRST STAGE ALARM FOR 12.5% LOW AIR PRESSURE
On a first level low pressure alarm the monitor will alarm
at 12.5% below the programmed base line air pressure.
When this happens the backlight on the monitor screen
will light up. The green led light will go out, the Red
warning light will begin to flash. The audible beeper will
cycle at 1 flash or beep per second, the alarmed wheel
position will be displayed. The pressure of the low tire,
and the words LOW PRESSURE will be displayed on the
monitor (see Figure 4-1). The audible alarm can be silenced by pressing any of the
buttons. The monitor will continue to display the wheel position, air pressure of the
alarmed wheel position and the words LOW PRESSURE until the problem is corrected. If
the alarm comes on and the FAST LEAK icon appears (see Figure 4-2), this means the
tire is losing air at a rate faster than 4.5 PSI in a 16 second period. The FAST LEAK icon
will only be displayed during the fast leak and will go out when the air quits leaking from
the tire. We suggest that the tire be inspected immediately.
2. SECOND STAGE ALARM FOR 25% LOW AIR PRESSURE
On a level 2 Low Pressure Alarm the monitor will alarm when the pressure has reached
25% below the programmed baseline air pressure.
The National Highway and Traffic
Safety Administration considers a tire flat when the pressure is 25% below the tire
manufacturers’ recommended operating pressure. When this happens the backlight on
the monitor screen will light up. The green led light will go out, the red warning light will
begin to flash. The audible beeper will cycle at 2 flashes or beeps per second and the
alarmed wheel position will be shown with the pressure of the low tire. The words LOW
PRESSURE will be displayed on the monitor similar to Figure 4-1. The screen will display
the same information as a Low Pressure Level 1 Alarm. The audible alarm will be silenced
by pressing any of the buttons. The monitor will continue to display the wheel position,
