Creating doorbell ring detection-based
events
Knowing someone's at the door doesn't seem like a big deal.
However, with doorbell chimes in random locations, usually away
from central living areas, all it takes is some loud music or a
family member with poor hearing to miss someone at the door.
Using the Doorbell and Phone Event Package, you can create
a home automation event that alerts the homeowner when the
doorbell is pressed.
For example, the event can cause a room's lights to flash, mute an
audio zone's speaker volume, or trigger an IP camera by the door.
These instructions provide you with ideas for added capabilities
you can provide to your customers and walk you through the
setup process to implement these ideas.
The Doorbell and Phone Event Package easily integrates with
Control4 and a homeowner's installed doorbell. It includes the
ELK-930 that detects ring activation, isolates the voltage and
current, and produces an open collector (pull-to-ground) output
used to trigger a contact close event in the package's Wireless
Contact Sensor.
Installing the hardware
Step one: Connect the ELK-930 Doorbell Detector and Wireless
Contact Sensor to the doorbell circuit.
1 Using the INPUT terminals, wire the ELK-930 Doorbell
Detector Module into the circuit path between the doorbell
transformer and the doorbell.
2 Run one wire of similar gauge to the doorbell wire from
the OUT terminal on the Doorbell Detector Module to the
SWITCH 1 terminal on the Wireless Contact Sensor's Tray
Assembly.
3 Run another wire of similar gauge from the NEG terminal on
the Doorbell Detector Module to the COMMON 1 terminal on
the Wireless Contact Sensor's Tray Assembly.
Step two: Place the Doorbell Detector Board and Wireless
Contact Sensor.
1 After connecting the Wireless Contact Sensor to the
ELK-930 Doorbell Detector Module, you can place it above
the doorbell chime façade that covers the plunger/solenoid
using the contact switch's enclosed molly anchors.
2 After making all the wire connections between the circuit
path, the Wireless Contact Sensor, and the ELK-930
Doorbell Detector Module, you can secure the module to an
appropriate surface using the two included adhesive pads.
Note: Often the façade covering the plunger/solenoid
activating the doorbell chimes is large enough to
conceal the Doorbell Detector Module.

Programming in Composer Pro
Step one: Add the Wireless Contact Sensor driver to the
Composer project.
1 Open Composer Pro and the project, then select the System
Design view.
2 Under Search, enter Control4 Wireless Contact Sensor.

3 Select the contact sensor to add it to the project.
Step two: Add lighting events to rooms.
1 In System Design View, add (if needed) the desired light
switch to the event room.
2 Add a generic doorbell sensor driver to the room where the
event will take place.
3 In Connections View, bind the Doorbell driver's Contact
Sensor input to the appropriate contact output of WCS10A.

4 Go to the Programming View, and from the Device Events
window in the upper left, select Doorbell.
