Controlling
Window Treatments
The
examples shown in this newsletter 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. Click
on the link below to see an example wiring diagram:
Connecting
2 Wire Window Treatments to the M1
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.

3 Wire Window Treatments to the M1
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.
|
WHENEVER
TIME OF DAY IS
8:00AM
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.
|
WHENEVER
TIME OF DAY IS
8:00AM
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.
|
WHENEVER
Area 1(Area 1) IS ARMED AWAY
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.
|
WHENEVER Watch Movie (Task 5) IS ACTIVATED
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.
|
WHENEVER
F6 ON KEYPAD 2 ACTIVATES
THEN ACTIVATE Watch Movie (Task 5) |
