Tecnoalarm Tecnofire TFA1-298 Installation Manual page 44

Supervision of jumpers
The control panel oversees the open or closed state of the jumpers to prevent that they are forgotten in the wrong position after
use, causing potential undesirable behaviors or malfunctioning of the control panel.
The control panel notifi es the condition of anomaly, through a screen that indicates System failure and KEY jumper inserted.
The signaling remains visible until the relevant key jumper is correctly positioned.
N.B. If the Automatic system failure acknowledgment function is not enabled, it is also necessary to perform a manual
acknowledgment to cancel the System failure notifi cation.

USB port
The USB port allows to connect the control panel directly to a PC, for programming of the control panel and upgrade of its
fi rmware. This connection supports only the standard Tecnofi re protocol from the Tecnoalarm and TECNOMONITOR software. The
USB interface can also be enabled by an access level 3 or 4 code, to allow access to the data Flash memory of the control panel
as a disk drive and customize the vocabulary using the Tecnoalarm software.
Serial port
The TTL port allows to connect a PC via the PROG32 or PROG USB interface, for programming of the control panel and upgrade
of its fi rmware. This port has longer transfer times compared to the USB port. The TTL port also allows to connect a serial printer.
