A burglar alarm is designed so that it senses four input signal lines. Line A is from the secret control switch, line B is from a pressure sensor under a steel safe in a locked closet, line C is from a battery-powered clock, and line D is connected to a switch on the locked closet door. The following conditions produce a logic 1 voltage on each line.

A : The control switch is closed.

B : The safe is in its normal position in the closet.

C : The clock is between 1000 and 1400 hours.

D : The closet door is closed.

Write the switching expression for the burglar alarm that produces a logic I (rings a bell) when the safe is moved and the control switch is closed, or when the closet is opened after banking hours, or when the closet is opened with the control switch open.
