Trigger Input Design Application
The COM2’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.
