The Model D-23R Bill Trap Transmitter is a unique device used in banks and other places where cash is handled in sizable quantities. Baited with currency, the transmitter is hidden beneath the stack of bills in a cash drawer. Removing the "bait" bill from the holding clip transmitts a signal which is repeated at 45-second intervals until the bait bill is replaced (the repeat timer can be disabled by cutting an internal jumper). Operating in conjunction with a suitable receiver, this transmitter sends signals which are used to trigger alarms and other security devices, such as video cameras. Completely portable, the D-23R works even when cash drawers are being moved, if it remains within RF range of the receiver. Each transmission causes the red LED indicator on the transmitter to light, showing that the transmitter is sending a signal and that the battery is in good condition.
