If the supply voltage drops below 75% of the nominal line voltage, the power LED will
turn "off." This provides a visual check of low line voltage that can be caused by the start up of
a gate motor. The Model B operates with line voltage as low as 85 VAC.

(Also used to enter loop diagnostics mode).
• RESET Resets the detector to the "No Call", i.e. no vehicle detected state.

Output Delay tPIP Switch 41
A two-second delay of Outputs A and B can be activated by setting DIP switch 4 to the ON position.
Output delay is the time the detector outputs are delayed after a vehicle first enters the loop detection area.
If the 2 second Output Delay feature is activated, the output relays will only be turned on after 2 seconds
has passed with a vehicle continuously present in the loop detection area. If a vehicle leaves the loop
detection area during the 2 second delay interval, detection is aborted and the next vehicle to enter the loop
detection area will initiate a new full 2 second delay interval. By flashing the front panel DET LED at 4 Hz
with a 50% duty cycle, the detector indicates that a vehicle is being detected but that the outputs are being
delayed.
Sensitivitv Boost (DIP Switch 51
DIP switch 5 can be turned ON to increase sensitivity only during the detect period, without changing the
sensitivity of a vacant loop. When a vehicle enters the loop, the detector then automatically boosts the loop
sensitivity but only during the detect condition. As soon as no vehicle is detected, the detector immediately
returns to the original sensitivity level. This feature helps prevent dropouts during the passage of high-bed
vehicles and is particularly useful in sliding gate situations.
Pulse Mode (DIP Switch 61
Output B is the pulse output. The output B relay can be programmed to output a pulse only upon vehicle
entry over the loop or only upon vehicle exit from the loop. When DIP switch 6 is OFF, the detector will
output an "entry pulse" each time a vehicle enters the loop detection area. When DIP switch 6 is ON, the
detector will output an "exit pulse" each time a vehicle leaves the loop detection area. The factory default
is OFF, i.e. entry pulse. (DIP switch 6 has no effect on Output A, the presence output).
Presence Hold Time (DIP Switch 7)
Output A is the presence output. The detector has two presence hold time modes: TruePresence™ and
Limited Presence. Both modes output a "Call", i.e. vehicle detected, for as long as a vehicle is present in
the loop detection area. TruePresence™ will hold the Call for as long as the vehicle is present and power is
not removed or reset applied. Limited Presence will typically hold the Call output for about one to three
hours. The TruePresence™ time provides a detection output condition for the entire time the vehicle is
present in the loop zone. The TruePresence™ time applies only for normal size automobiles and trucks and
for normal size loops (approximately 12 ft ^ — 120 ft ). The factory default for DIP switch 7 is OFF, i.e.
TruePresence™ mode By setting DIP switch 7 ON, the detector will operate in Limited Presence mode.
Output B Mode (DIP Switch 8)
The Output B relay has two modes of operation; either Pulse (ON) or Presence (OFF). When in the pulse
mode, the pulse can be either pulse on entry or pulse on exit (see "Pulse Mode - DIP switch 6"). When in
the presence mode, the presence hold time is the same as Output A (see "Presence Hold Time - DIP switch 7).

FreaufinfY
Loop frequency is controlled by the FREQ switch on the fr ont panel. Sometimes when loops are in close
proximity, it may he necessary to select different frequencies for each loop to avoid loop interference ~
commonly known as crosstalk. Four frequencies labeled "High" to "Low" are available. Each time the
FREQ button is momentarily pushed, the next higher frequency is selected. The next frequency aiter High
is Low. Note: Immediately after each change of frequency, the detector is automatically reset; therefore
there is no need to push the RESET button.
Call Memory . „ , „ ,
When power is removed for 2 seconds or less, the detector automatically remembers if a vehicle was
present and a Call was in effect. When power is restored, the detector will continue to output a Call until
the vehicle leaves the loop. (Power loss or dips of 2 seconds or less will not bring a gate arm down onto
cars as they wait at the gate).
Failed I.nnn Diagnostics
The FAIL LED indicates whether or not the loop is currently within tolerance. If out of tolerance, the LED
indicates whether the loop circuit is shorted or open. If and when the loop returns to within tolerance, the
FAIL LED will resume the OFF condition indicating "Loop OK".
Additionally, the detector automatically stores the last loop failure type in non-volatile memory. To
determine the last loop failure, press the FREQ key for three seconds or more. When the FAIL LED begins
fl ashing at 1 Hz with 5% duty cycle, release the FREQ key. The detector will then display the last loop
failure type detected (if any). This indication will be displayed one time for about fifteen seconds unless
terminated by pressing the RESET or FREQ key. The non-volatile memory used to store the last loop
failure type is automatically cleared each time it is interrogated.
Fail Mode
Two versions of the Model B detector are manufactured: Fail Safe, Model B-#, and Fail Secure,
Model B-#(S). In the Fail Safe version, when the loop fails in any manner or power is removed, the Output
A relay assumes the state indicating Call. In the Fail Secure version, when the loop fails in any manner or
power is removed, the Output A relay assumes the state indicating No Call.

Loop Installation
Mark the loop layout on tt'ie pavement. Remove sharp inside comers that can damage the loop wire insulation.
Set the saw to cut to a depth (typically 2" to 2.5") that insures a minimum of 1" from the top of the wire to pavement surface.
The saw cut width should be larger than the wire dianeter to avoid damage to the wire insulation when placed in the saw
slot. Cut the loop and feeder slots. Remove all debris from the saw slot with compressed air. Check that the bottom of the
slot is even.
It is highly recommended that a continuous lengtii of wire be used to form the loop and feeder to the detector. Loop wire
is typically 14, 16, 18 or 20 AWG with cross-link polyethylene insulation. Use a wood stick or roller to insert the wire to the
bottom of the saw slot (do not use sharp objects). Nftfrap the wire in the loop saw cut until the desired number of turns
is reached. Each turn of wire must lay flat on top of the previous ti/n.
" The wire must be twisted together a minimum of 6 twists per foot from the end of the saw cut to the ctetector.
<^>— The wire must be held firmly in the slot witfi 1" pieces of backer rod every 1 to 2 feet. This prevents the wire from floating
when the loop sealant is applied.
Apply the sealant. The sealant selected should have good adhering properties with similar contr^ion and expaision
characteristics to that of the pavement material.
