 This inbound relay trigger contoller provides 800 ms of dry contact closure. This unit is simply bridged to the door box leads. It's activated by the push button on the door box. Use it to sound a door chime so a seperate chime is heard the same time the phone rings or activate a camera. You can use your existing door chime with this also.
This item can also be used for activating door bells, strobe lights or other indicators, selecting a camera on a switcher to show the particular door that someone is at or other types of automation.
This item does not provide power to operate an external device. You will switch an external power source through the dry closure on this item which will go to a bell or light.
