Occupancy sensor w/ override

[Volta]

Who knows what brand I should be looking at for a wall switch type OS that has an override setting or switch for both on and off?

I could not quickly find any on either Leviton's or Wattstopper's sites.

watt stopper has them. I'll have to look for a part # but the most definitely have them in wall or ceiling mount.

I think Leviton, Wattstopper, and Sensorswitch all have them.

I don't think its exactly a straight manual on and manual off switch.

I think its more like programming the switch to be manual on/auto off as opposed to auto on/ auto off.

With manual on/manual off, press the button once and the lights turn on, press it again and they go off. Of course, they always go off after a certain time delay.

What's the line voltage and load type?

P&S and RAB also.

That's what I'm trying to avoid, at least in 1 of 7 rooms. Such as what would be needed to comply with 210.70(A)(1) Exeption 2.

120 vac feeding ballasts for T-8s. Six are offices, 1 is a small conference room.

Thanks, but the LOS series seems like they are all auto-off. The Maestro series claims "Uses the Lutron-exclusive XCT? technology for sensing fine motions to ensure the lights remain on when the room is occupied", which might be ok, but still looking for something that has an integral override such as could comply with 110.26(D), though it won't be used that way.

I think the problem is that any Occ Sensor that does that would not comply with the energy codes. So you may not be able to find one.

The handbook says occ. sensor may be used if manual switches are also provided. Not sure how you would do that - if you put a toggle switch in parallel it would give you a manual on, and the occ sensor would have a manual off. But that seems like a convoluted solution.

It is possible that I won't find any. But in these locations toggle switches already exist, it does not seem unreasonable to look for an OS that allows such control. But maybe I offered more than I can deliver on ...

Leviton and others make residential grade stuff with on-auto-off slide witch with the on off performing a permanent over ride, but they don't work with fluorescent lighting. I see them installed and permanently left on "on" all the time.


There are commercial grade ones for ballast loads and can be configured for manual on-off auto-off, or auto-on manual off auto-on but I don't know any that offers permanent over ride in "on mode".

P&S(and its brand WattStopper) includes re-trigger function though. If for some reason it shuts off, a motion within 30 seconds or so of shut off will reactivate the lights even if "auto on" is disabled. The maximum shut off timer setting is 30 minutes. I don't think you can get around this.

But... the sensor should be placed where it can see occupancy, like near the conference area. Not at the entry. There are remote sensor systems available.
