Common Control Triggers
The B&K CT receiver line incorporates common control triggers that can be used for whole house events
such as telephones and doorbells. Two common controls on the six zone receiver (one on the three zone)
allow up to 24VAC or DC voltage sensing. Referred to as Page/Events, typical applications might involve a
doorbell and front door security camera. For example, when the doorbell is pressed, the CT receiver will
switch all zones to the specified A/V source input that the camera is connected to. The user can specify
which zones should or should not respond to either or both Page/Events. Wiring diagrams for specific appli-
cations are available through B&K. Please visit our website or contact our Customer Service Department for
specific applications. The diagram below illustrates the installation of a front door security camera coupled
with a doorbell. The Page/Event is default set to switch to input 8 when a voltage is detected through
Common Control 1 IN- and IN+.
