Ditek DTK-2MHLP36B Hybrid Surge Protector 36V 3 Pair

Product Description

The DITEK DTK-2MHLP36B is a hybrid surge protector designed for fire alarm and life-safety signaling circuits operating at 36 volts. It combines multiple protection stages in a single plug-in module, providing transient voltage suppression for low-voltage control and signaling lines. The plug-in, no-base configuration allows direct installation into compatible panel terminals without a separate mounting base, simplifying field replacement. Fire alarm technicians and low-voltage contractors install this device to protect sensitive initiating and notification circuit wiring from voltage spikes caused by lightning, power induction, and switching transients. Each unit covers three pairs of conductors.

This protector is suited for fire alarm systems, mass notification circuits, and other 36-volt life-safety signaling applications where conductor pairs require transient voltage protection at the panel or field device end. The plug-in form factor makes it a practical choice for periodic replacement during routine fire alarm inspections or after a surge event. Its hybrid protection design addresses both common-mode and differential-mode transients across all three pairs simultaneously.

Key Features

• Hybrid multi-stage surge protection for 36-volt signaling circuits
• Protects three pairs of conductors in a single module
• Plug-in, no-base design for direct panel installation and fast field replacement
• Addresses both common-mode and differential-mode transient events
• Intended for fire alarm and life-safety low-voltage circuit protection

Compatibility

Designed as an OEM-style plug-in surge protector for 36-volt fire alarm and life-safety signaling panel circuits requiring three-pair transient voltage protection.

Installation Notes

Installation should be performed by a licensed fire alarm technician or low-voltage contractor in accordance with NFPA 72 and applicable local codes. De-energize the affected circuit and follow the panel manufacturer's lockout procedures before removing or installing the module. Verify the panel accepts the plug-in, no-base module format before installation. Do not substitute this device on circuits with voltage ratings outside the 36-volt specification.
