- Fixing centres 48 to 74mm
Summary
The Hochiki YBN-R/3 is a common mounting base built to speed up sensor installation across Hochiki’s ESP range, cutting down the time you spend on each head during first fix and commissioning. Because it’s fully compatible with the ESP sensor range, you can standardise on one base across a site and avoid juggling different fixings for different detector types.

For you on site, that means faster first fix, fewer wiring errors and a tidier job to hand over. The stainless steel contacts and rugged wiring design give you confidence the connection will hold up over the life of the installation, reducing callbacks.
It delivers this through a simple, electronics-free design that accepts cables up to 2.5mm², terminated via square cable clamps for a secure fix without fiddly screw terminals. A facility for a remote indicator is also built in, so you can wire through to a remote LED where the sensor itself is out of sight.
Features
- Electronics free – nothing on the base to fail or fault-find, so troubleshooting stays with the sensor head
- Stainless steel contacts – resists corrosion for a reliable connection over the system’s lifetime
- Takes 2.5mm² cables – accepts standard fire alarm cable sizes without adapting terminals
- Slim profile – only 8mm – sits close to the ceiling for a discreet finish
- Rugged wiring contacts – built to withstand repeated connection and disconnection during commissioning and maintenance
- Facility for remote indicator – wire through to a remote LED where the detector is hidden from view
- Quick connection via square cable clamps – speeds up termination compared with loose screw terminals
- Available in white, ivory and black – lets you match the base to the ceiling or sensor finish on site
FAQ
Yes, the YBN-R/3 is a common mounting base designed to be fully compatible with Hochiki’s ESP range of sensors, so you can fit it ahead of confirming the exact detector head. The base includes a facility for a remote indicator, so it is capable of driving a remote LED where required. Check the installation instructions for the specific sensor fitted to confirm wiring and current limits for the remote LED circuit. The terminals take cables up to 2.5mm², which covers standard fire alarm cabling, and termination is made via square cable clamps rather than loose screw terminals. Fixing centres run from 48mm to 74mm, giving you some flexibility to match existing ceiling box centres without needing a different base variant. No, the YBN-R/3 is electronics free. All detection electronics sit in the sensor head itself, so the base is purely a mechanical and wiring interface that is unlikely to be a source of faults. The base is available in ivory, white and black, ordered as YBN-R/3, YBN-R/3(WHT) and YBN-R/3(BLK) respectively.Is the YBN-R/3 compatible with all Hochiki ESP sensors?
