Controlling The Garage Door

Have you ever left home, been well on your way, and thought, “Did I shut the garage door?”  Your only option is to drive all the way back home, right?  Not with M1…  The garage door can be programmed to close several minutes after you leave or use the built-in telephone remote control feature check the state of the door and close, if needed. 

Here is another common scenario.  It’s late at night and you are not sure if the garage door is closed.  With M1, a programmable F key on the keypad can light up or even blink when the door is open and you can close the door by pressing the F key, eliminating the need for those late night trips to the garage!

 
Hookup
Important Note: The application note is recommended ONLY for use with garage door openers that comply with the latest government safety requirements (i.e. those with automatic reversing mechanisms and electronic photo eye sensors that detect obstructions). If your garage door does not have these government-mandated safety features, replace or update your garage door opener before attempting to use this application note.  FOR MORE INFORMATION PLEASE REFERENCE THE DOCUMENTATION PROVIDED BY THE MANUFACTURER OF THE GARAGE DOOR OPENER. 

Other Garage Door Safety precaution:  Audible Closer Sounders: Some municipalities and manufacturers recommend a Mini Sounder (Piezo) be connected that will provide audible warning prior to and during operations of the garage door closer motor.    
Garage Door Contact
In order for the M1 to know when the door is open or closed, a door contact must be installed and connected to an available input (zone) on the M1 system.  A garage door or overhead door contact switch is designed specifically for this application, as they provide a larger operating gap and can withstand the pressure of a vehicle driving over the sensor without damaging it.  The garage door contact connects to the M1 similarly to a standard door contact.

 

Connecting the M1 to the Garage Door Opener
The garage door opener has one or more inputs for the connection of a device such as a push button for operating the opener.  Using a dry contact relay, the M1 is connected to this input, allowing control of the opener by activating an output on the system.  In  Figure 1, the on-board relay (Output 3) is used.  In Figure 2, voltage output 7 is used to trigger a separate relay that is connected to the opener.

Programming
In the examples below, the garage door will open or close when the F4 key is pressed on any keypad, or when button 3 on the wireless keyfob is pressed. 

WHENEVER F4 KEY ON ANY KEYPAD ACTIVATES
          THEN TURN Garage Door (Out 3) FOR 5 SECS 

  WHENEVER RF KEYFOB BUTTON 3 IS ACTIVATED
          THEN TURN Garage Door (Out 3) FOR 5 SECS
 

The next rule will announce the state of the door after it is fully opened/ closed, using the voice description for the zone.   The voice description is set up in RP on the screen for each zone, under inputs.  

The voice description is set up in RP on the Zones (Input) screen for each zone. The [Say Closed/Open] option allows the M1 to  announce the actual state of the door at the time the message is used.



Using this rule, the M1 can announce the state of the door after it is fully opened/ closed.

WHENEVER Garage Door (Out 3) STATE IS TURNED OFF
          THEN ANNOUNCE Garage Door (Zn 3)

You can easily program an F key to be lit or blink when the garage door is open.  This is an option on the keypad screen in RP.   Just set the illumination event to the zone of the garage door (zone 3 in this example), and check the box under ‘blink light’ if a blinking light is desired. 


 

In the following rules, an unused output (output 208 in this example) will be turned on for 5 minutes when the system is armed in away mode.  If the garage door is still open when the unused output is turned off, it will be closed.   You can adjust the length of time that the unused output is turned on, which will allow the door to stay open for more or less time before automatically closing. 

WHENEVER Area One (Area 1) IS ARMED AWAY
          THEN TURN Output 208 ON FOR 5 MINS 

  WHENEVER Output 208 STATE IS TURNED OFF
       AND Area One (Area 1) IS ARMED AWAY
       AND Garage Door (Zn 3) IS NOT SECURE
          THEN TURN Garage Door (Out 3) ON FOR 5 SECS
  
For added convenience and safety, the rule below will turn on the garage light and an outdoor light, if the garage door is opened when it is dark outside. 

WHENEVER Garage Door (Zn 3) BECOMES NOT SECURE
     AND IT IS DARK OUTSIDE
          THEN TURN Outdoor Light [5 (A5)] ON FOR 5 MINS
          THEN TURN Garage Light [6 (A6)] ON 

The M1 can also remind you to close the garage door if it has accidentally been left open.  With the rule below, if the garage door is still open at 9:00 PM , the M1 will announce “Garage Door Is Open.”  Just press the F key (F4 in this example) on any keypad to close the door! 

WHENEVER THE TIME IS 9:00 PM 
     AND Garage Door (Zn 3) IS NOT SECURE
          THEN ANNOUNCE Garage Door (Zn 3)
