addind dry contact output to an airflow alarm
(OP)
This is for an airflow alarm. I designed this simple airflow alarm and all is working well. When the airflow is above the setpoint a green LED is on. When it falls below the setpoint a red LED comes on. If the airflow falls below the setpoint for more than five seconds a buzzer comes on. When a button is pressed the buzzer is silenced. I'm trying to add a dry contact output to my alarm. If I just used the buzzer output to drive the relay it would go off if the alarm was silenced. I would like for the relay to stay activated until the buzzer is silenced and the airflow goes above the setpoint. I've attached a better explanation.

It has been said so many times that this is EngTips, not WeDesignForYou. There is a difference between tip and full service.
