- A public restroom needs to have lights on, but even if there is no one is around.
- So how does one avoid leaving the lights on unnecessarily.
Approach 1: Sensor based - person comes, lights on; person leaves, lights off
- Restrooms often have windows and the natural light during daytime is enough to light the room, but the sensors will still activate the lights which results in wasted energy.
Approach 2: Install a rocker switch
- The lights are turned on when needed, but afterwards they stay on because no one bothers to turn them off.
K24 Wall Mounted Sensor Switch:People come, lights on; people leave, lights off.
- Both a sensor and a wall switch are present at the same time.
- Delay time is adjustable.
- Even though power is supplied, lights will only turn on from the switch or the sensor.
K15 Ceiling Mounted Sensor Switch:People come, lights on; people leave, lights off; with the option to add a wall switch for manual control.
K25 Fixed Time Switch
Single Channel Usage With Sensor
- Main lights with exhaust fan: Fixed time control, main lights and exhaust fan are connected separately.
- Auxiliary lights: Connected to a K15 sensor for delayed auto off.
Dual Channel Usage
- Main Lights: Lights turn on and off at preset times during the day.
- Auxiliary Lights: Lights can be manually operated any time of the day with delayed auto off capability.
- Each restroom can have a K86 installed with a classic switch, which will allow for the power to be supplied without the lights turning on.
- There is no need to turn on the lights when the natural light is enough, and hence no one would want to turn on the lights. When it is dim, the user would naturally want to turn on the lights.
- When night falls, power is automatically cut off then restored which will turn off the lights, when a user comes they can still turn on the lights
