Breakwire contacts
The BREAKWIRE contacts are similar to the STANDBY contacts, and are clearly labeled. A loop of wire
is connected to the standby contacts to detect if the target package was opened. When the BREAKWIRE
loop is broken, the transmitter sends alarm tones.
Button and LED operation
The RESET button and STATUS LED are visible on the edge of the beacon. The button is designed to be
accessed with a pen or paper clip. Care must be used to depress the button and not the LED, lest the
beacon be damaged. The location of the RESET button is clearly labeled.
Depressing the button at any time will cause the internal microprocessor to respond with three flashes of
the LED, and an “OK” tone will be transmitted. Further, internal timers will be reset. This allows the
beacon to be installed, and then tested prior to deployment.
Reset to Default
When the button is held depressed for five seconds or more, the LED will flash five times. The
microprocessor will reset all parameters to their factory-default values, and the processor will perform a
cold reset. Since, all the operational parameters are stored in non-volatile memory, this is a way to set a
beacon to a known mode of operation, in the field, without the need for a computer.
Operator programming
The program and cradle supplied for the LB-1 allows it to be programmed on any PC running DOS or
Windows. It is a very simple, easy-to-use program. Below is a screen-shot of the program in operation.
Note that as the program is revised, the screen may differ slightly from that shown, but the operation will
be essentially similar.
