MONITOR THE POSITION OF YOUR GARAGE DOOR WITH A LAMP IN YOUR HOME

Garage Door Position Indicator This project will monitor the open or closed position of your garage door, and indicate that position by turning a lamp, or lamps, on or off. The lamp can be located throughout your home to provide an indirect visual indication of the door’s position. A magnetic security sensor (contact reed switch) monitors the door’s position. Control of the lamp is accomplished by using Universal Powerline Bus (UPB) devices. One UPB device senses the position of the garage door and transmits a control signal, and another UPB device, to which the lamp is connected, receives the control signal and turns the lamp on or off. Multiple lamps will require multiple UPB devices.

MORE EQUIPMENT INFORMATION:
There are a variety of contacts that can be used for this application. For simplicity, the US131SP was chosen. This is an “NO” contact. Contacts come in both “NO” and Normally Closed (NC) configurations. In security lingo, the “normal” position is when the object being monitored is in the secured, or “ready-to-arm,” position. If the garage door is secured, or closed, the magnet attached to the garage door attracts the reed of the contact switch installed on the door jamb, and it pulls the reed switch open. There will be no continuity across the two wires of the contact. When the garage is opened, the magnet is no longer in proximity of the contact switch and the reed springs back to the closed position. There is now continuity across the two wires of the contact.

The computer interface module is necessary for configuration of the I/O and lamp modules. The interface module is also the physical connection between a PC or laptop’s serial port and the electrical power line. Communication between the PC and the interface module is through a software application called UPStart. Links, dimming, light level presets, and device testing can all be configured and performed through UPStart.

The universal phase coupler allows signals that originate on one side of the incoming electrical power to be coupled, or bridged, to the opposite side of a residential single-phase, 120/240 VAC electrical system. The coupler ensures that the signal will be present on both sides of the incoming AC power.

The I/O module detects the presence, or lack of, continuity from the contact switch, and is configured to transmit control signals known as links. The links are transmitted throughout the home by using the electrical wiring, hence the term “powerline.”

The lamp module responds to the links transmitted by the I/O Module. The lamp used to indicate the garage door’s position is connected to this module. For this application, the lamp module will be configured to turn on or off only. Dimming, light level presets, and fade rates will not be used.

HOW TO INSTALL IT:

US131SP Installation

1. Locate an appropriate spot on the garage door jamb for the contact switch. The contact can be attached by either adhesive tape or by using small screws. The screw method is preferred.
2. With the garage door closed, attach the magnet to the door such that it is in proximity of the switch. Use an ohm meter to verify the following on the switch:
   
   Garage door closed - meter reads infinity or very high resistance, open circuit, “O.L,” switch is open.
   
   Garage door open – meter reads very low resistance, 0.0 ohms, short circuit, switch is closed.
   
3. Ensure that the magnet and the contact switch do not interfere with the normal operation of the garage door.
4. Using the 22 AWG hook-up wire, connect and extend the wires from the contact switch to where the I/O module will be located.

SAUZPCW, UPB Universal Phase Coupler Installation

1. Reference the manufacturer’s instructions for the phase coupler installation.
2. Turn off power for the branch circuit where the coupler is to be installed at the circuit breaker panel.
3. Connect the black wires across a 220V VAC circuit.
4. Connect the white wire to neutral.
5. Turn on power at the breaker and verify that the three LED’s on the coupler are now illuminated.
   

SAUMI32W, UPB Input/Output Module

2. Connect the wires from the contact switch to terminals 9 and 10 of the I/O module, Input #2, Contact Closure.
3. Plug the I/O module into an electrical receptacle.
   

SAUML20W, UPB Lamp Module

1. Reference the manufacturer’s instructions for the lamp module.
2. Connect the lamp to the module.
3. Plug the lamp module into an electrical receptacle.

UPStart Configuration

1. Launch the UPStart application and ensure the connection icon states “Online.”
2. Click File, New Network File, then OK.
3. Click Device, Add, and follow the instructions for adding a new device. Devices to be added are the I/O module and Lamp Module.
4. The following configuration is for the I/O Module:
   
   • In the Transmit Components tab, click on Open Link Name Table. Click on New.
   • For Link001, change the name to Secure_Light Off.
   • Click on New and for Link002, change name to Not Secure_Light On. Click on Close.
   • Back in the Transmit Components tab of the I/O Module, set the following:
     
     Input 2, Mode = Custom Input
     Open Event Link Name = Secure_Light Off, Open Event Command 1 = Activate
     Close Event Link Name = Not Secure_Light On, Open Event Command 1 = Activate
     
     
   • Click on Program Device after every field entry. Click on OK when complete.
     
     
5. The following configuration is for the lamp module:
   
   • In the Options tab, set Dimming = Not Enabled, Default fade rate = Snap! Click Program Device.
   • In the Receive Components tab, set the following:
     
     01 Link Name = Not Secure_Light On, Level = 100%
     02 Link Name = Secure_Light Off, Level = 0%.

SUMMARY
The lamp will turn on when the garage door is opened, and the lamp will turn off when the door is closed.

The contact switch triggers the I/O module. The I/O module contains two links, one called Not Secure_Light On and Secure_Light Off. If the garage door is open, the I/O module transmits the Not Secure_Light On link and the lamp module responds to it by turning on to 100%. When the garage door is closed, the I/O module transmits the Secure_Light Off link and the lamp module responds by going to 0% and turns off.
