DITEK DTK-2LVLPLV surge protector security

SKU CH-AKTP-9NC6D MPN DTK-2LVLPLV

Protects two communication pairs for 4-20mA loops and alarm circuits, accepting 22-16 AWG wiring with 27V clamping

  • Protects two communication pairs from surges
  • Safeguards 4-20mA current loops and alarm circuits
  • Handles #22-#16 AWG wiring connections
  • Operates at 27V for low-voltage data lines
  • Compact hard-wire design for easy installation

Application scope

The Ditek DTK-2LVLPLV is a hard-wired surge protector built for low-voltage signal, data and loop circuits. It suits installers securing 4-20mA current loops, alarm panel NAC, SLC and IDC loops, plus burglar alarm panels. Two communication pairs are protected in one compact block. It is not for mains-voltage power lines or high-speed Ethernet links.

Sustained behaviour

The unit clamps transients on each pair at 27V, letting normal loop current pass while diverting surge energy away from sensitive panels. Its solid-state design has no moving parts or replaceable cartridges, so protection remains consistent over repeated events. The device does not interrupt the circuit during normal operation.

Installation profile

Connections accept #22 through #16 AWG wires, allowing direct termination without adapters. No external power supply or cooling is required, and the sealed housing adds no audible noise. Power draw is negligible, limited to the tiny leakage of the clamping elements under standby conditions.

Questions about this item

Does the DTK-2LVLPLV generate heat or noise when protecting alarm loops continuously?

The DTK-2LVLPLV is a passive surge protector with no moving parts or active components, so it operates silently and produces no measurable heat during continuous operation.

What wiring must already be in place for the DTK-2LVLPLV to connect?

The unit accepts #22 to #16 AWG solid or stranded conductors, so existing loop wiring within that gauge range can be terminated directly to its screw terminals.

Will the DTK-2LVLPLV work with older 4-20 mA current loops and alarm panel circuits?

Yes, it is designed for 4-20 mA loops, NAC, SLC and IDC circuits at 27 V, protecting two communication pairs on legacy burglar and fire alarm panels.
