Both the FingerTec TCP/IP and RS485 surge protector provides a high level protection against voltage peaks and spikes caused by lightning and other power surges. The surge protectors are shielded with a metal case aluminum enclosure and also EMI noise suppression that will not interrupt the communication. They are also equipped with an integral ground wire to connect to a single point ground connection (metal chassis) to facilitate proper grounding. It is recommended that the surge protector should be installed as close as possible to the FingerTec devices to better protect the terminals. |
