Transmitter Features:

DB1-MC transmitters operate using auxiliary power source. DB1-MC is coded at the manufacturer with a unique address

ID. The test and low battery LED are not operational on these units. With proper voltage input the RED LED will illuminate

and the DB1-MC will transmit a doorbell alert to the Silent Call Medallion series receiver.

The DB1-MC Medallion Series Transmitter is designed for indoor use only. The transmitter case has provisions for

mounting to a nail or screw on the wall. Velcro strip is also provided for mounting on desktop or wall. Avoid mounting

transmitter near large metal objects, other transmitting devices in close proximity or high current appliances that will degrade

the transmitter / receiver operation. Test transmitter mounting location before mounting to ensure proper system operation.

Adjust antenna for best results. Transmission range with a Silent Call Medallion Series receiver is approximately 500 feet.

Locate your doorbell chime unit and remove the cover.

Inside the chime unit, locate the terminal block with three terminals marked FRONT, REAR and TRANS.

Loosen the two screws but do not disconnect the attached wires.

Attach the two wires from the DB1-MC as follows: Red to FRONT, and yellow to REAR.

Tighten the two screws and tuck and excess wires out of sight. Make sure all wires are clear of the chime mechanism

and reattached the chime unit cover.

Mount the Doorbell transmitter to the wall next to the chime unit or to the chime unit cover.

Pair DB1-MC to intended Medallion Receiver. Follow Programming procedure in Receiver installation manual

Whenever the front (or rear, if used) doorbell button is pressed, the chimes will sound as usual AND the Red LED on the

doorbell transmitter will light up. The transmitter then sends a RF signal to a preprogrammed Medallion Series Receiver

activating the Doorbell alert.

Both the front and rear doorbells will activate the doorbell transmitter.

the 12 -24VAC range
