<p num="1"><br/><br/><br/>An exit alarm system housed in an escutcheon for activating upon movement of <br/>an <br/>interior latch operator. The system is mounted to the interior side of a door <br/>with a latch <br/>assembly including an interior latch operator. The system may include an <br/>alarm, a trigger, <br/>and an electronic module. The trigger is responsive to movement of the <br/>interior latch <br/>operator. The electronic module may be electrically connected to a power <br/>source for <br/>providing an input signal to the alarm. Upon motion of the interior latch <br/>operator, the <br/>trigger may cause the electronic module to send an activating input signal to <br/>the alarm. <br/>The alarm may be a sound transducer. A switch may be provide to arm the <br/>system. A <br/>tamper switch may be provided to cause the electronic module to activate the <br/>alarm upon <br/>removal of the escutcheon. The system may be applied to retrofit an existing <br/>door.<br/>
