DITEK DTK-4LVLPX Data and Signaling Circuit Surge Protector, 12V Hardwired Signaling Circuits (Replaces DTK-3LVLPX)

Protect critical low-voltage signaling and data loops in access control, alarm and surveillance installations with the DITEK DTK-4LVLPX surge protector. This DITEK low-voltage surge suppressor is engineered to safeguard 4-20mA current loops, alarm panel NACs, SLC and IDC loops, and burglar alarm panels—minimizing service calls and preserving system uptime. The compact hardwired 4-pair package installs easily inside control enclosures and supports both AC and DC circuits; it’s designed for 12V hardwired signaling and is compatible with common 14V supply systems. Because the unit uses a series connection with a parallel function that adds no resistance, it maintains loop integrity for sensitive monitoring and data communications. TAA/NDAA and RoHS compliant and manufactured in the US, the DTK-4LVLPX includes a 10-year limited warranty for long-term protection of your security and surveillance assets. Ideal for installers and integrators who need dependable data line protection for access control and monitoring applications—add the DTK-4LVLPX to your next project or contact us for compatibility guidance.
