Linear ST-23A Supervised Bill Trap Transmitter

The Model ST-23A Supervised Bill Trap Transmitter is a battery powered cash drawer bill trap with a built-in transmitter designed for use with Linear’s S1 Format receivers. This transmitter can be used in a variety of retail hold-up applications.

The ST-23A 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 ST-23A can send three different signals: alarm, restore, and low battery.

The ST-23A continuously monitors its battery voltage. If the voltage is tested low, the transmitter will send a low battery transmission to the receiver. Because the radio signal from the transmitter may not reach the receiver when the cash drawer is closed, a motion detector is incorporated into the transmitter to determine the drawer position. Low battery transmissions occur every hour and up to once every five minutes whenever the drawer is opened.
