The way to wire two or more motion detectors to control one or more outdoor light fixtures is to wire a control circuit where the motion detectors are connected to one control relay, and the control relay will turn on the light fixtures. Using this method, the light fixture is activated by either motion detector.

Can you have multiple motion sensors on one circuit?

A light can be controlled with more than one motion sensor. Whether it’s for security, convenience or a way to be hospitable to unexpected visitors, a motion sensor wired to a light will brighten up the approach to your house when guests or intruders come in range.

How do you wire multiple motion sensors?





Quote from the video:
Quote from Youtube video: So if you're only running one wire. Then you have your ground which is this copper wire I'm taking off here first and then you have a black wire. And you have a white wire. And they come pre trimmed.

Can motion sensors be wired in series?

When wiring a motion sensor, you will generally want to use Normally Closed wiring. This may also be referred to as Series wiring. If you have multiple motion sensors connected with the same zone, they will be wired in series. You may also want to use an end of line resistor (EOLR) with your motion detectors.

Can occupancy sensors be wired in parallel?

Senior Member. I agree with both, but you may still require multiple sensors, and yes they are fine in parallel. You should be able to find how they are wired in the device’s instructions.

Can you wire two PIR sensors together?

OK then – yes you can have two PIR’s to operate one light.

Can you fit two PIR sensors together?





It will work fine just ensure that both PIRs are fed from the same circuit.

Can you put 2 motion sensor on a three way switch?

When using in a 3-way application use one sensor and one standard 3-way switch. Cannot be used with another sensor, or in a 4-way application. WARNINGS AND CAUTIONS: If you are not sure about any part of these instructions, consult an electrician.

How do you wire a PIR in series?

Quote from the video:
Quote from Youtube video: Different positive and negative to power up the sensor. From the positive of the zone. There's the 4k7 resistor the 4k7 resistor then links to the first terminal of the tamper.

Can you have two sensor lights one switch?

Yep, it’s fine to run sensors to operate a light or lights. Just need to wire the sensors in parallel.

What is the difference between a motion sensor and an occupancy sensor?



The Occupancy sensor detects presence of people or animals in the target monitored area. The motion sensor responds to moving objects only. The difference between them is occupancy sensor produce signals whenever an object is stationary or not while motion sensor is sensitive to only moving objects.

What is the difference between a vacancy sensor and an occupancy sensor?

When the occupant exits, the sensor automatically indexes the lights back to ‘OFF’ after a programmed delay – typically between two and 15 minutes depending on user preferences. Vacancy sensors take that control one step further with a manual on setting, as opposed to automatic on.

How do you wire a 3 way occupancy sensor?

Quote from the video:
Quote from Youtube video: Important you do not mix them up now the other black wire will be connected to this black wire then brass screw now the blue wire will be connected on the red wire.

Can PIR sensors be wired in series?



Fortunately, since PIR sensors have NC and COM contacts, it is possible to connect any number of them together in series to generate a single cumulative output signal which will be high (signal voltage) when motion is not being detected and low when motion IS detected – i.e. the cumulative signal will act just like the

Can you link PIR sensors?

Make sure you use PIR sensors that are designed to be connected in parallel. Not all are. Those with a relay on the output should be OK. You could set them up so they each control certain lights.

How do I connect two PIR to one zone?

Two PIR sensors wiring (tamper switch connection)



We use four color wires for this connection, including red (+12 power), black (GND, Zone -), green (Zone +), white (connection wires between two sensors). Red and black wires to connect power supply, and green color wire should connect to zone +.

Why are resistors used in alarms?

The reason alarm resistors are called “end of line” resistors is because by placing the resistor at the end device (motion detector or door/window contact) the circuit can be monitored for shorts in this manner.

What is tamper connection?



A tamper switch is a mechanical and electrical device connected to a fire protection valve that signals a warning if the valve partially or fully closes. Regardless of the type of switch, they all function similarly. These devices feature an actuating unit, usually a lever or cable with a resting position.

How are alarm systems wired?

As the name suggests, a wired or hardwired home security system relies on wires running through your house to send information back to the central control panel, triggering alarms or notifications when appropriate and notifying your security company if that is part of your service package.

How do you connect alarm wires together?

Quote from the video:
Quote from Youtube video: And what I'll do is I'll just match them together and have left these bits up here for now because it makes it easier to grip the cable. So I'm just going to twist that gently in the fingers.

Is a wired security system better than wireless?

Wired security systems aren’t susceptible to electromagnetic or structural interference, so the signals are more reliable. They require virtually no upkeep because there are no batteries to swap out or charge. You also won’t end up with an unexpected power failure from poor battery life.
