What alteration would occur if a single pole switch is reconnected to become a master switch?
If a single pole switch is wired to be a master switch, the switch would have to be in the on position for any other control devices to operate. Turning the master switch off would eliminate power to all devices (and/or loads) which it was serving. For example, some homes have a switch to control their outside light. If the outside light has a photo eye (the light will only come on at night), the switch is the master switch. Another example would be the breakers in an electrical panel. Each breaker would be the "master switch" for the circuit it protects. The main breaker in the panel would be the "master switch" for the entire home.

How do you reset EML Technologies motion sensor light?
Some photo cell units have an over ride on them. If your photo switch has a switch ahead of it, the over ride may have inadvertently been turned on. Try this in the daytime. If the light is continuously on use the switch to shut the power off to it within a 10 second interval. An example, light on, flip switch off for five seconds and then back to the on position. Wait to see is the unit times out and turns the lamps off. The large knob under the unit is probably the sensitivity control or the time on till off control.
