aanthony Posted December 5, 2010 Posted December 5, 2010 Can someone explain (to a beginner) the differences for the status of a relay (on/off) and sensor (on/off) Can I assume you could program the I/OLinc so that the sensor is on if the door is closed or off if open. I basically want to open or close the door using a keypad button and have the button show the status (lit if open, unlit if closed).
LeeG Posted December 5, 2010 Posted December 5, 2010 The I/O Linc Sensor can be wired to either be On when the door is closed or On when the door is open. The SmartLinc garage door kit comes with a magnetic switch that has both NC and NO switches built in. Depending on which switch you chose to use depends on the state of the I/O Linc Sensor when the door is closed. If you have a magnetic switch that is only NO or only NC and the I/O Linc Sensor is operating opposite to what you want, there is an I/O Linc option the ISY can set called Trigger Reverse which reverses the On/Off command relationship to the Sensor On/Off state. Normally when the Sensor turns On it sends an On command, and when it turns Off it sends an Off command. The Trigger Reverse option reverses that. When the Sensor turns On it sends an Off command and when the Sensor turns Off it sends an On command. You can get whatever commands you need. The problem with trying to use a single KPL button is that the button LED represents whether the KPL button is On or Off and whether the door is open or closed. You can do what you want but I was never comfortable knowing whether the KPL button LED was telling me if the door was open or closed or that the KPL button was On or Off. With ISY Programs you can do it and others have.
AnthemAVM Posted December 5, 2010 Posted December 5, 2010 Funny, this is something that I am trying to set up again in my new house. Have you been to this page on the Wiki? http://www.universal-devices.com/mwiki/ ... e_Door_Kit
oberkc Posted December 5, 2010 Posted December 5, 2010 I have set up my garage door IOLinc and Keypad just as you suggest. I used the wiki instructions suggested by AnthemAVM. They work great. You must pay attention to details, but my keypad is on when the door is open and off when closed. Pushing the button activates the door, just like pushing the hard wired button in the garage. While the ISY-99 makes setup much easier, there is a post at Smarthome from one who did it without an ISY. (There is no program required.) Configuring the devices can be done manually, apparently. I was impressed.
