extended period of time. When Option 4 is set to 4.00, the detector will track out the vehicle (i.e.
drop the detection of the vehicle) in four minutes to several hours depending on the amount of
inductance change (-
ΔL/L) caused by t
he vehicle when it is detected. The greater the change caused
by the vehicle, the longer the time needed to track out the vehicle. When Option 4 is set to 4.01,
4.02, 4.03, 4.04, 4.05, 4.06, 4.07, 4.08, or 4.10 the option is
ON
, and the detector will provide
extended detection times.
There are many factors that influence the proper setting of this option. A full explanation of how to
determine the correct setting is beyond the scope of this manual. Contact a Technical Support
representative at Reno A&E regarding proper setting of this option.
NOTE: Using this option in a long loop application is not recommended. The detector will drop the
call prior to the vehicle totally exiting the loop.
4.00 = Tracking Rate 0.
4.01 = Tracking Rate 1.
4.02 = Tracking Rate 2.
4.03 = Tracking Rate 3.
4.04 = Tracking Rate 4.
4.05 = Tracking Rate 5.
4.06 = Tracking Rate 6.
4.07 = Tracking Rate 7.
4.08 = Tracking Rate 8.
4.10 = Tracking Rate 10.

OPTION 5: SENSITIVITY BOOST
Each loop input’s Option 5 has five settings ranging from 5.00 to 5.04. When Option 5 is set to 5.00, the option is
disabled (
OFF
), and no sensitivity boost is added. When Option 5 is set to 5.01, 5.02, 5.03, or 5.04 the option is
ON
, and sensitivity boost is enabled. After detection, the sensitivity is boosted to the currently selected sensitivity
level plus the number of level(s) selected. The maximum sensitivity level which can be obtained with or without
sensitivity boost is level 10.
5.00 = Off (no sensitivity boost).
5.01 = 1 level of sensitivity boost.
5.02 = 2 levels of sensitivity boost.
5.03 = 3 levels of sensitivity boost.
5.04 = 4 levels of sensitivity boost.

OPTION 6: AUDIBLE DETECT SIGNAL
Each loop input’s Audible Detect Signal setting can be toggled
ON
or
OFF
by momentarily pressing either the
(UP) or
(DOWN) pushbutton. Only one loop input can be turned
ON
at a time. Turning this option
ON
for one
loop input automatically turns it
OFF
for the other loop inputs. When this option is enabled (
ON
), an audible
signal will be activated whenever the detection zone for the selected loop input is occupied. The audible signal
indicates actual occupancy of the loop detection zone. This feature allows a technician to watch the detection zone
and confirm correct detector operation without having to look at the detector display as well. NOTE: This option
is automatically disabled 15 minutes after activation or on loss of power.
2.9
LOOP CHECK
The Loop Check feature provides a means of automatically verifying the proper operation of each loop circuit.
The Loop Check Timer can be set for an interval ranging from 0 to 255 minutes in one-minute increments. A
setting of
000
indicates that the Loop Check feature is off.
