INSTALLATION INSTRUCTIONS
590-00
DOOR CHIME ACTIVATED SYSTEM
The circuit below, Fig. 1, shows a simple means of using a door chime or door bell to activate one of the inputs on a Xantech Model 590 Programmable Controller, to initiate a system function or functions. Functions that may be initiated by this system, might include the following:
•Switch the AV system source selector to a front door surveillance camera.
•Turn on front door intercom.
•Mute the audio in an A/V system.

Fig. 1 A Door Chime Activated System
The circuit uses a rectifier and a zener regulator to take the 24 to 28 volts AC from the chime coil and convert it to the necessary 12 volts DC to drive the input on the controller.
To implement this circuit, proceed as follows:
1.Build the circuit using the parts shown.
2.Place the assembled parts in a small metal box.
3.Connect the input of the circuit to the chime coil terminals as shown. Note: Do not connect it to the door chime
4.Program the 590 with the necessary remote commands to drive the control components.
Caution: Do not connect this circuit to any other terminals on the 590 except the pair of input terminals you wish to assign to it!
