SINGLE CHANNEL LOOP DETECTORS
INSTALLATION AND OPERATING INSTRUCTIONS
I. General
Please verify source voltage before applying power. The model designation indicates the input power required, output
configuration, sensitivity boost configuration, and Fail-Safe / Fail-Secure configuration for the detector as follows.
Model B-xx-xx-x Blank = Fail-Safe, S = Fail-Secure
Blank = Internal DIP switches set to True Presence TM / Pulse-on-Entry
DP = Internal DIP switches set to True Presence TM / True Presence TM
SB = Internal DIP switch set to enable Sensitivity Boost
3 or 1 = 120 VAC
4 or 5 = 12 VDC / 24 VDC / 24 VAC
8 or 35 = 240 VAC
NOTE: Models B-3, B-4 and B-8 are fitted with a rear mounted, 11-pin, Amphenol style connector. Models B-1,
B-5, and B-35 are fitted with a rear mounted, 10-pin, MS style connector.
The detector is factory configured for either Fail-Safe or Fail-Secure operation (see unit side label). The output state of
each output relay in either Fail-Safe or Fail-Secure mode is listed in the table below.

II. Indicators and Controls
i. Power / Detect / Fail LEDs
The detector has one green and two red LED indicators that are used to provide an indication of the detector’s
power status, output state, and/or loop failure conditions. The table below lists the various indications and their
meanings.
Status PWR (Power) LED DET (Detect) LED FAIL LED
Off No power or low power Output(s) Off Loop OK
On Normal power to detector Output(s) On Open Loop
Flash N/A
4 Hz (50% duty
cycle)
Two second timing
delay activated
1 Hz (50% duty cycle)
Shorted Loop
1 Hz (5% duty cycle)
Waiting for release of FREQ pushbutton
to enter diagnostics mode
(See Failed Loop Diagnostics)
NOTE: If the supply voltage drops below 75% of the nominal level, the PWR LED will turn off, providing a
visual indication of low supply voltage. Model B detectors will operate with supply voltage as low as 70% of
nominal supply voltage.
ii. Frequency LEDs:
The four red LED indicators provide an indication of the current detector operating frequency.
iii. Front Panel Pushbutton Switches:
Two momentary contact, pushbutton switches are used to control the following.
RESET - Push the front panel mounted pushbutton labeled RESET to reset the detector.

FREQ - In situations where loop geometry forces loops to be located in close proximity to one another, it may be
necessary to select different frequencies for each loop to avoid loop interference, commonly known as crosstalk.
The front panel mounted pushbutton labeled FREQ can be used to configure the detector to operate at one of four
(4) frequencies corresponding to Low, Medium / Low, Medium / High, and High. Press the FREQ pushbutton to
toggle through and select one of the four frequency settings.
NOTE: After changing the frequency setting, the detector must be reset by pressing the front panel RESET
pushbutton.

Sensitivity (DIP Switches 1, 2, and 3)
DIP switches 1, 2, and 3 select one of the eight (8) sensitivity levels available as shown in the table below. 0 is the
lowest setting, 3 is normal, and 7 is the highest setting. Use the lowest sensitivity setting that will consistently
detect the smallest vehicle that must be detected. Do not use a sensitivity level higher than necessary.

1 OFF OFF OFF OFF * ON ON ON ON
2 OFF OFF ON ON * OFF OFF ON ON
3 OFF ON OFF ON * OFF ON OFF ON
* Factory default setting.
Output Delay (DIP Switch 4)
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 zone. If the two second
Output Delay feature is activated, the output relays will only be turned on after two seconds have passed with a
vehicle continuously present in the loop detection zone. If the vehicle leaves the loop detection zone during the
two second delay interval, detection is aborted and the next vehicle to enter the loop detection zone will initiate a
new full two second delay interval. The detector provides an indication that a vehicle is being detected but that the
outputs are being delayed, by flashing the front panel DET LED at a four Hz rate with a 50% duty cycle. The
factory default setting is OFF (no Output Delay).
Sensitivity Boost (DIP Switch 5)
DIP switch 5 can be turned ON to increase sensitivity during the detect period without changing the sensitivity
during the no detect period. The boost feature has the effect of temporarily increasing the sensitivity setting by up
to two levels. When a vehicle enters the loop detection zone, the detector automatically boosts the sensitivity level.
As soon as no vehicle is detected, the detector immediately returns to the original sensitivity level. This feature is
particularly useful in preventing dropouts during the passage of high bed vehicles. The factory default setting is
OFF (no Sensitivity Boost) unless sensitivity boost (SB) operation is specified, in which case the factory default
setting is ON (Sensitivity Boost).
Relay B Pulse Mode (DIP Switch 6)
Relay B is the pulse output. Its pulse output mode is controlled by DIP switch 6. Relay B can be configured to
output a single 250 millisecond pulse when a vehicle enters the loop detection zone (Pulse-on-Entry) or when a
vehicle leaves the loop detection zone (Pulse-on-Exit). Pulse-on-Entry is selected when DIP switch 6 is OFF.
Pulse-on-Exit is selected when DIP switch 6 is ON. DIP switch 6 has no effect on Relay A (the presence output).
The factory default setting is OFF (Pulse-on-Entry).
NOTE: The setting of this DIP switch has no effect on the output mode of Relay B if DIP switch 8 is set to the
OFF position (Presence Mode Relay B). For additional details, refer to the Relay B Output Mode section on
page 3.
