Light when someone is there.
Dimmed when they are not.
This is the R3148-MS. A 5.8 GHz microwave sensor that plugs into the centre of the hi bay. It turns the light up when it sees movement and dims it back when the area is empty.
In one sentence: the R3148-MS is a Rapid LED plug-in microwave motion and daylight sensor for the R3117 and R3118 ORBIT hi bays, for mounting heights up to 15 m.
Sensor only. The programming remote is sold separately.
It works out of the box on its default settings. To change them you need the R3148-REMOTE.
- R3148-MS plug-in microwave sensor
- A Rapid LED R3117 or R3118 ORBIT hi bay
- The R3148-REMOTE to change settings (optional)
Plug in, no rewiring.
The sensor plugs into the socket under the hi bay. Out of the box it detects across 100% of its range, holds the light on for 3 minutes, and ignores daylight. The remote changes all of that.

Fits
The socket in the middle.
The R3117 and R3118 have a sensor socket in the centre of the LED board. The R3148-MS plugs in and dims the hi bay on its 0–10 V control line.

Plug it in and go.
01
Power off
Isolate the hi bay before fitting the sensor.
02
Plug it in
Push the sensor into the socket in the centre of the hi bay and turn it to lock.
03
Power on
It runs on its defaults: 100% detection area, 3-minute hold, daylight sensor off.
04
Fine-tune (optional)
Use the R3148-REMOTE to set detection area, hold time, daylight level and standby dimming.

Sensor or Casambi?
| R3148-MS sensor | R3148-CAS Casambi | |
|---|---|---|
| Control | Motion and daylight, automatic | Bluetooth app, scenes and schedules |
| Set up with | R3148-REMOTE | Casambi app on a phone |
| Network | Each light works alone | Up to 250 lights in one network |
Both plug into the same socket on the R3117 and R3118 ORBIT hi bays. One light takes one module.
Common questions
Is the remote included?
No. The R3148-REMOTE is sold separately. The sensor works on its defaults without it.
What are the default settings?
100% detection area, 3-minute hold time and daylight sensor disabled.
How high can it be mounted?
Up to 15 m, with a detection range of about Ø16 m.
Does it dim the light or switch it off?
Both are possible. After the hold time it drops to a standby level of 10, 20, 30 or 50%, and the standby period can be set from 0 seconds to always on.
Does it react to daylight?
Yes. It has daylight harvesting and a daylight threshold from 2 to 400 lux, or the daylight sensor can be disabled.
Do I need an electrician?
No rewiring is needed. The sensor plugs into the socket on the hi bay. Isolate the light before fitting it.
Which hi bays does the R3148-MS fit?
Rapid LED R3117 and R3118 ORBIT hi bays. Rapid lists it for these ORBIT hi bays only.
What is the warranty?
5 years (2 years replacement and labour, 3 years replacement only), with proof of purchase.
