Reno A&E BX-8 240V BX Series Single Channel Loop Detector
The Reno A&E BX-8 is the 240 VAC member of the BX Series single-channel detector family. It is intended for vehicle detection systems where the control cabinet supplies 240 VAC to the detector socket and the site uses one inductive loop for vehicle presence. This type of detector may be found in barrier gate cabinets, industrial gate operators, parking access lanes, traffic control panels, and access-control installations that were built around line-voltage detector power. Like other BX Series detectors, it provides one loop input and dual relay outputs, with setup through external DIP switches and a sensitivity rotary switch. The BX-8 should be ordered only when the original detector or wiring diagram confirms 240 VAC detector power. In older systems, the wrong voltage detector can be damaged immediately, so the cabinet voltage should be measured before replacement.
Compatible With
- Select gate operators, barrier gates, parking controllers, and access-control panels using a 240 VAC 11-pin single-channel detector.
- BX Series applications calling for BX-8, BX8, or Model BX-8.
- Vehicle loop functions such as safety, exit, presence, hold-open, pulse-on-entry, and pulse-on-exit when the controller wiring supports those outputs.
- Older 240 VAC Reno detector installations where a BX-8 is specified by the parts diagram or detector label.
- 11-pin detector socket or harness installations when the pinout and high-voltage wiring are confirmed.

Technician Note
Treat BX-8 replacements as high-voltage service work. Verify source voltage and de-energize the cabinet before touching detector wiring or socket terminals.
Before Ordering Checklist
- Confirm the old detector label or wiring diagram calls for BX-8 or 240 VAC.
- Measure detector socket voltage with proper test equipment.
- Confirm the socket and harness are not heat damaged.
- Record relay wiring and DIP switch settings before removal.
- Check the loop and lead-in wiring if the old detector showed fail indications.
Important Ordering Warnings
- BX-8 must not be installed on a low-voltage or 120 VAC detector circuit.
- Use a qualified technician if the cabinet contains live high-voltage wiring or unknown modifications.
Professional Advisory
Vehicle loop detectors and related wiring parts should be installed with the operator power off and tested with the gate, barrier, or door system in a controlled position. Do not bypass required safety devices. If the installation involves high voltage, damaged conduit, wet junction boxes, or uncertain relay wiring, use a qualified gate or access-control technician.
Product Questions and Answers
What voltage is the BX-8?
BX-8 is the 240 VAC version of the Reno A&E BX Series single-channel loop detector.
Can BX-8 replace BX-3?
No. BX-8 is 240 VAC and BX-3 is 120 VAC. The detector voltage must match the control cabinet.
What is the BX-8 used for?
It is used for one-loop vehicle detection in gate, barrier, parking, and access-control systems that supply 240 VAC to the detector.
Does BX-8 have dual relay outputs?
Yes. BX Series detectors are commonly listed with dual relay outputs for presence, pulse, and related loop functions depending on configuration.
What should be checked before ordering?
Confirm the original part number, voltage, socket type, relay wiring, and loop condition before ordering a replacement.
