Datasheet4u offers most rated semiconductors data sheet pdf. This will amplify the musical sound so that you can hear it properly and from distance also. Opa dual channel, 27 v, railtorail inputoutput fet.

The data sheet clearly shows a 5k daasheet 10k resistor on the output. The reset switch zeroes the count,and the 7 segment display is a common cathode type. The IR detector circuit in principle, converts the IR signal pulse trains into noticeable aural notes.

To save power consumption the display can be enabled or disabled with a switch as shown in the above diagram. The envelope of the chime is set by the k, k, 3u3 and 4u7 resistors and capacitors.
