Ditek DTK-2MHLP36F Surge Protection Module 6V 2 Pair

Product Description

The DITEK DTK-2MHLP36F is a two-pair surge protection module designed for fire alarm and life safety signal circuits operating at 6 volts. It provides transient voltage surge suppression on low-voltage data and signal lines, protecting connected equipment from damaging voltage spikes caused by lightning strikes, switching transients, and induction events. The module includes a load removal feature that disconnects the protected load under sustained fault conditions, helping to maintain circuit integrity. Fire alarm systems technicians install this device at the field-wiring interface to safeguard panel inputs and notification appliance circuits.

This module is intended for use in fire alarm signal circuits where two-pair protection is required at 6 volts nominal. Typical installation scenarios include protecting initiating device circuits and supervisory circuits at the point where field wiring enters the control panel enclosure or a junction point exposed to outside or long-run cabling. It is suited for both new construction and retrofit applications in commercial and residential fire alarm systems.

Key Features

• Two-pair surge protection covers both conductors of each signal pair simultaneously
• 6-volt operating rating matched to low-voltage fire alarm signal circuits
• Integrated load removal function disconnects the load under sustained fault or overcurrent conditions
• Modular design supports fast field replacement without rewiring the full circuit
• Designed for fire surge protection category applications in life safety systems

Compatibility

Designed as an OEM-style replacement or new-installation surge protection module for two-pair, 6-volt fire alarm signal circuits requiring load removal capability.

Installation Notes

Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and local authority having jurisdiction requirements. De-energize and place the fire alarm control panel in a controlled state before connecting or replacing the module. Follow the manufacturer data sheet for terminal assignments and grounding requirements. Verify that the protected circuit voltage and pair count match this module before installation.
