Yes, both the sensor/transmitter featured in the DCPA-4000 (which is the DCPT-4000) and the DCMT-4000 you mentioned may be programmed/paired to the same receiver. The DCPA-4000 kit comes with one sensor/transmitter (DCPT-4000) and one receiver, the DCR-4000. The DCR-4000 will work with up to 16 different transmitters/sensors. If both sensors are paired to the receiver (The DCR-4000), the receiver will play the selected melody for that sensor. For example, if the DCPT-4000 is triggered, you may have the receiver (DCR-4000) play the ding-dong sound, and when the DCMT-4000 is triggered, you could have the receiver play the sound melody or a different one.
