Signal Protection for 24 V Circuits

The DITEK DTK-2MHLP24BWB is a hybrid surge protector built for 24 V service voltage. It shields two pairs of voice, data or signalling lines using multi-stage SAD technology. A field-replaceable edge-card module and single-point ground allow quick installation on a hard-wired multi-base that can cover up to ten pairs.

Suited for Fire and Security Loops

Installers protecting fire-alarm NAC, SLC, PIV or IDC circuits, burglar-alarm NAC and IDC circuits, or 4-20 mA current loops will find the 20,000 A surge rating and 39 V clamping voltage appropriate. The 5 A continuous current limit and 2 Mbps maximum data rate make it unsuitable for high-speed Ethernet or power distribution circuits.

39 V Clamping Voltage Decides Fit

The protector clamps transients at 39 V while the maximum continuous operating voltage is 33 V. If the connected equipment cannot tolerate a 39 V let-through, a different suppressor must be chosen.

Questions about this item

What wiring must already be in place for the DTK-2MHLP24BWB to protect a circuit?

The module requires a 24 V AC or DC signal, data or loop circuit with two pairs to protect, plus a hard-wired multi-base that provides the single-point ground connection.

Will the protector pass signals from older 200 kbps equipment without degrading the link?

Yes, the unit supports data rates from 200 kbps up to 2 Mbps, so legacy low-speed circuits remain within the specified bandwidth.

How can I confirm the module is clamping correctly after installation?

Measure the line-to-ground voltage under normal operation; it should stay below the 33 V MCOV, and any transient should be limited to the 39 V clamping level.
