Linear Battery Powered Cash Drawer Bill Trap DXT-81

The Model DXT-81 Bill Trap Transmitter is a battery powered cash drawer bill trap with a built-in transmitter designed for use with Linear's DX Format receivers. This transmitter can be used in a variety of retail hold-up applications.

The DXT-81 is concealed in a cash drawer under a stack of currency, with a single bait bill secured in its money clip. During a hold-up, the cashier removes the stack of currency along with the bait bill. When a bait bill is removed, the transmitter sends a 1-second digitally coded wireless signal to its companion receiver. Four additional 1-second signals are sent within the first minute after the bait bill is removed. When the bait bill is replaced, a restore signal is sent.

The digital DX code format features over a million possible codes. The DX transmitters are precoded at the factory to unique codes, so no field coding is required. The DXT-81 can send three different signals: alarm, restore and low battery.

Inside the transmitter is a rolling ball that detects when the cash drawer opens and closes, this determines when low battery transmissions are sent. Because the transmitter's signal might be shielded in a closed cash drawer, the low battery signals are sent when the drawer is opened and every hour thereafter.

The transmitter has a red test indicator which lights when a bill is in the trap and the test button is pressed. It also lights when the bait bill is inserted into the trap. For safety, the indicator doesn't light when the bait bill is removed. The test indicator will not light when pressing the test button with the bait bill removed.

The test button is disabled for 60-seconds after removing the bait bill. Pressing the test button without a bill in the trap sends an alarm signal. Pressing the test button with a bill in the trap sends a restore signal.

The unit is powered from two 2032 3-Volt lithium batteries with an expected battery life of up to two years. When the batteries get low, the test indicator will flash when the test button is pressed or when the bait bill is replaced.
