326 Single Channel Inductive Loop Vehicle Detector

Please Select Voltage and Failsafe/Failsecure Below

Features & Benefits

• Compatible with all radio control and remote

• Features latest state-of-the-art surface
mount technology.

• Sensitivity Boost, selectable by setting an
external DIP switch, eliminates possible
detector dropout during passage of
high bed vehicles - this feature is
particularly useful in sliding gate

• External rotary switch for 10
selectable sensitivity levels.

• Two color LED status indicator for Detect,
Power, and Loop Fault indication.

• Self-tuning & complete environmental

• No warm-up required.

• Continuous Winky-Blink™ loop monitor which
remembers and indicates intermittent and
failed loops - a great troubleshooting aid.

• If intermittent or failed loops self-heal, the
detector will resume normal operation without
manually resetting the detector.

• Four front panel selectable loop frequencies
permit elimination of crosstalk.

• Large loop inductance range: 20 to 2000
microhenries, allowing operation with a wide
range of loops.

• 11-pin Amphenol rear connector.

• Two separate output relays:
- Output A is presence output
- Output B, programmable with external DIP
switches, provides presence, pulse on entry,
pulse on exit, or fail output

• An infinite presence mode is available by
setting an external DIP switch.

• Both outputs can be delayed for 2 seconds,
by setting an external DIP switch, causing the
detector to ignore vehicles passing over the
loop faster than about 5 miles per hour.

• Both outputs can be extended for 0 seconds,
2 seconds, 5 seconds, or 10 seconds,
programmable with external DIP switches.

• Detector will not retune if power is lost for a
minimum of 3 seconds and then restored.
Prevents vehicle detection from being lost
during brief power interruptions.

• ABS plastic case.

• LV Series - Universal Low Voltage Input,
accepts 12V to 24V AC or DC.
Only TWO configurations required: failsafe or
failsecure. Standard models available in 120
VAC or 240 VAC, failsafe and failsecure.
