3.5 DB41-MC INSTALLATION:
1. Locate your doorbell chime unit and remove the cover.
2. Inside the chime unit, locate the terminal block with three terminals marked FRONT, REAR and TRANS.
3. Loosen the two screws but do not disconnect the attached wires.
4. Attach the two wires from the DB41-MC as follows: Red to FRONT, yellow to REAR.
5. Tighten the two screws and tuck and excess wires out of sight. Make sure all wires are clear of the chime mechanism.
6. Replace the chime box cover.
7. Other applications are possible. The DB41-MC will activate when it is connected to a source of voltage between 12V and
24V AC or DC.
3.6 DB41-MC OPERATION:
1. Whenever the front (or rear, if used) doorbell button is pressed, the chimes will sound as usual, the Red LED on the face of
the doorbell transmitter will light up and the transmitter will send a signal to any Silent Call Medallion Series Receiver
activating the receiver.

3.7 DW3-MC INSTALLATION:
1. Mount the magnet on the door or window so that it clears the door jamb or window frame and does not interfere with normal
door or window operation.
2. Mount the magnetic switch so that it is as close to the magnet as possible when the door or window is closed. Spacing should
be less than approximately ¼”.
3.8 DW3-MC OPERATION:
1. When the door or window moves enough that the magnet is separated from the switch, the red LED on the transmitter will
light up. The transmitter will then send a signal to any Silent Call Medallion Series Receiver activating the receiver. The
transmitter will transmit for approximately five seconds and then stop until the door or window is closed. The door or
window must be closed for approximately five seconds before the transmitter will reset and be ready to activate again.
