PTI Offers Built-in Surge Protection

As summer arrives with its spectacular thunder and lightning storms, sensitive electronic and computer equipment—and any equipment interconnected by cables over long distances—require the installation of surge suppressors. All PTI products include some level of surge protection on the power and communication (RS485) lines.

To protect against voltage surges from power lines and on the RS485 communication line, the Falcon System uses surge suppression and self-resetting fuses. The VP Series Keypads have built-in surge suppression on both the RS485 lines and on the power supply lines that protect against voltage surges from the power source or external sources such as lightning and ESD from automobiles. The APEX series keypads offer surge protection on the power supply, ESD protection on the keypad and communication lines, surge protection and optical isolation on the RS485, and isolated grounds to protect against ground faults. Door Alarm Multiplexers have surge and ESD protection on the power, communication, and door switch lines.
