How To Control Window Treatments with the M1

Simplify your life by programming your M1 Security & Automation Control open and close your blinds or drapes. The examples below illustrate controlling wired window treatments (such as motorized blinds and drapes) that use voltage polarity reversal to control the direction of the window treatment.  These window treatments have internal up and down limit switches to disengage the voltage upon reaching the limits.  Some of these window treatments have two wires, which requires 2 relay contacts to “reverse” the polarity.  The ELK-924 used in conjunction with a voltage output from the M1 can be used for these types of window treatments. 

Other window treatments may have 3 wires (1 negative and 2 positive), which requires one relay contact to switch the voltage to the appropriate positive lead.  This can be done using a single relay from M1 System using the  ELK-M1XOVR Output Expander and/or ELK-M1RB Relay Board.  The M1XOVR connects to the M1 data bus and provides 8 relay outputs and 8 voltage outputs.  The voltage outputs of the M1XOVR can be converted to relays using the M1RB.  The M1RB can also be used to convert voltage outputs 9-16 on the main board to relay outputs.  Another option is to use an ELK-912 controlled by a voltage output from the M1.  Click the link below to see an example wiring diagram.

Using rules, these window treatments can be controlled by turning outputs on or off, allowing them to open/close based on time of day, system arm status, task activation, etc. 


Time of Day:
Blinds or drapes in particular rooms should be opened at a certain time to let natural light into the room.  The window treatments should only be opened if the system is disarmed or armed to stay mode.  In this example, the living room blinds will be opened in the morning at 8:00 am if the system is disarmed.

     AND Area 1(Area 1) ARM STATE = DISARMED
          THEN TURN LR Blinds (Output 9) ON

To open the blinds at 8:00 am if the system is armed in stay mode, simply change the AND statement in the rule as shown below.

     AND Area 1(Area 1) IS ARMED STAY
          THEN TURN LR Blinds (Output 9) ON

System Arm Status:
The blinds or drapes should all be closed when the system is armed to away mode, to prevent anyone from seeing in the home.  In this example, a group of window treatments will be closed when the system is armed in away mode.

          THEN TURN LR Blinds (Out 9) OFF
          THEN TURN MBR Blinds (Out 10) OFF
          THEN TURN Ktchn Blinds (Out 11) OFF

A similar rule may be used to close the window treatments when the system is armed to night mode.

Task Activation:
The window treatments may need to be opened or closed based on a task.  For example, when watching a movie, a task may be activated that dims the lights and closes the drapes.  The rule below defines that task.

          THEN SET LR Lights [1(A1)] TO 10% BRIGHT
          THEN TURN LR Drapes (Out 10) OFF

This task may be activated from the keypad Tasks menu or from an F key.  The rule below activates the task when the F6 key is pressed on the keypad in the living room.

          THEN ACTIVATE Watch Movie (Task 5)
