Ditek DTK-2MHLP24B 24V 2-pair Hybrid Surge Protection Module

Product Description

The DITEK DTK-2MHLP24B is a 24-volt, 2-pair hybrid field replacement surge protection module designed to protect low-voltage fire alarm and life safety signal circuits from transient voltage events. This module provides surge suppression on signal and control wiring, helping prevent damage to connected fire alarm panels, initiating devices, and notification appliances. It is a field-replaceable design, meaning the protective module can be swapped out after a surge event without replacing the entire base assembly. Fire alarm technicians and low-voltage electricians are the primary installers of this device.

This module is suited for fire alarm systems operating at 24 volts DC, commonly found in commercial and residential fire detection and notification installations. It protects two pairs of conductors simultaneously, making it appropriate for circuits such as initiating device circuits, signaling line circuits, or notification appliance circuits where transient protection is required. The field-replaceable format reduces system downtime during service calls following lightning strikes or power transients.

Key Features

• 24-volt rated operation for compatibility with standard fire alarm system voltages
• Protects 2 pairs of signal or control conductors simultaneously
• Hybrid surge protection technology for broad-spectrum transient suppression
• Field-replaceable module design allows fast swap-out without disturbing the base wiring
• Intended for fire surge protection applications on life safety circuits

Compatibility

Designed as a field replacement surge protection module for low-voltage 24-volt fire alarm and life safety signal circuits requiring 2-pair hybrid transient protection.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified low-voltage electrician in accordance with NFPA 72 and applicable local codes. De-energize the circuit and follow the authority having jurisdiction requirements before replacing or servicing any module on an active fire alarm system. The field-replaceable module should be seated fully into the base assembly to ensure proper contact and protection. Do not bypass or omit surge protection on life safety circuits after a transient event.
