Ditek DTK-2MHLP24F 24V 2-pair Hybrid Surge Module

Product Description

The DITEK DTK-2MHLP24F is a 24-volt, 2-pair hybrid surge protection module designed for field replacement in fire alarm and life safety systems. It combines gas tube and solid-state suppression technology in a single module to protect low-voltage signal and control circuits from transient voltage events. The field-replaceable design allows a technician to swap the protection module without removing or rewiring the base, reducing system downtime during service calls. Licensed fire alarm technicians and low-voltage contractors are the primary installers of this device.

This module is intended for use in fire alarm control panel installations and related life safety signaling circuits operating at 24 volts. It is suited for both new construction and retrofit applications where surge protection is required on 2-pair wiring runs. The hybrid design addresses both high-energy transients and fast-rise low-energy surges on the same circuit, making it appropriate for installations in areas with elevated lightning or electrical noise exposure.

Key Features

• Field-replaceable module design allows on-site swap without disturbing base wiring
• Hybrid surge suppression addresses a broad range of transient types on 24-volt circuits
• Protects 2-pair low-voltage signal and control wiring in fire alarm systems
• Sold as a single replacement module for fast restocking of spare inventory

Compatibility

Designed as an OEM-style field replacement module for 24-volt, 2-pair hybrid surge protection bases used in fire alarm and life safety signaling applications.

Installation Notes

Installation should be performed by a licensed fire alarm technician or qualified low-voltage contractor in accordance with NFPA 72 and local authority having jurisdiction requirements. De-energize the circuit and follow the fire alarm control panel manufacturer lockout procedures before removing or installing the module. The field-replaceable module seats into a compatible base — confirm base compatibility before ordering the replacement. Do not install on circuits operating above the rated voltage of the module.
