Trigger Input Design Application

The C2's Trigger Inputs are designed to accept a dry contact closure across the "+ " and
"-" terminals. An added benefit is that the Trigger Inputs provide 12VDC on the "+" terminal
and ground on the "-" terminal (see Figure 2-5). This provides the ability to illuminate lighted
doorbell buttons.
NOTE: Trigger inputs 1 and 2 will always trigger the Door Chime assigned to Door
Station 1 and Door Station 2 alerts respectively. In order to differentiate between
Door Stations 1 and 2 alerts and Triggers 1 and 2, set the I.D. DIP Switches on the
door stations DS 1 and DS 2 to DS 3 and DS 4. This will allow different alerts for the
two door stations and the two trigger inputs
