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