Why Choose the Optima Plus SMO
- Hands-free hygiene: infrared sensor activation improves cleanliness and user experience
- Fast retrofit: mounts at the handle location on exposed Sloan diaphragm valves (Royal, Sloan, Regal, Crown)
- Battery powered: runs on four C-cell alkaline batteries; no wiring required
- Manual override: built-in button provides a courtesy flush during maintenance or cleaning
- ADA-compliant activation: factory-set detection range covers typical user approach distances
- Low-maintenance design: includes sentinel flush to reduce stagnation and a low-battery indicator
Compatibility and Installation
- Works on most exposed Sloan diaphragm valve bodies (Royal, Sloan, Regal, Crown)
- Installs on either left- or right-hand handle sides
- Not compatible with piston valves (like GEM-2) unless adapters are used
- Does not change the flush volume, the gallons per flush are still determined by the diaphragm/regulator kit in your valve body
ProDryers Tips for Success
- Replace batteries proactively: C-cell batteries last about 3 years in typical use; keep spares ready to avoid downtime
- Watch sensor placement: avoid aiming the lens at mirrors or glossy partitions to prevent false triggers
- Confirm fixture GPF: always match the diaphragm/regulator to the fixture’s rated flow rather than adjusting the stop for more water
- Plan for service: keep one spare SMO kit or sleeve assembly on hand for high-traffic facilities, ensuring quick swaps if needed
Frequently Asked Questions
What does “SMO” mean?
It stands for Side-Mount Operator — a sensor module that mounts where the flush handle would be.
Is the EBV-89A-M battery powered?
Yes. It uses four C-cell batteries, with a low-battery indicator light and a sentinel flush feature.
Will it work on both toilets and urinals?
Yes, but flush volume still depends on the diaphragm/regulator kit in your valve body. The SMO provides the activation, not the flush rate.
Can I install it myself?
Installation is straightforward with basic tools. It mounts at the handle location and does not require plumbing behind the wall.
Does it include the flushometer valve body?
No. The EBV-89A-M is a retrofit operator only. If you need a complete valve, order a full Sloan flushometer that ships with the SMO pre-installed.
