Ditek DTK-2MHLP24FWB 2-pair 24V Fire Surge Protector

Product Description

The DITEK DTK-2MHLP24FWB is a 2-pair, 24-volt hybrid surge protection device engineered for fire alarm and life safety signal circuits. It combines a male plug form factor with an integrated base and loop-through wiring capability, allowing for clean in-line installation without cutting or splicing the protected circuit. Designed for use on low-voltage fire system signaling lines, this unit provides transient voltage surge suppression to protect connected panel equipment and field devices from damaging voltage spikes caused by lightning or switching transients. Licensed fire alarm technicians and system integrators are the primary installers.

This surge protector is intended for fire alarm signaling circuit applications operating at 24 volts DC, which is the standard bus voltage for the majority of conventional and addressable fire alarm control panels used in commercial and residential fire protection systems. The plug-and-base design allows the unit to be unplugged for quick replacement in the field without disturbing the base wiring, reducing system downtime during maintenance or after a surge event. It is sold as a single unit.

Key Features

• Hybrid surge suppression technology for low-voltage fire alarm signal lines
• Rated for 24-volt DC fire alarm circuits
• Male plug design mates with matching base for tool-free field swap-out
• Loop-through wiring support maintains circuit continuity during installation
• 2-pair protection covers two signal conductor pairs in a single device
• Categorized under fire surge protection for code-compliant deployments

Compatibility

Designed as an OEM-style surge protection solution for 24-volt low-voltage fire alarm signaling circuits in conventional and addressable fire alarm system installations.

Installation Notes

Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and applicable local fire codes. Power down or place the fire alarm control panel in a safe service mode before connecting or disconnecting the surge protector. The plug-and-base design allows the module to be removed and replaced without disturbing base wiring, but always verify loop continuity and system supervision after any service. Do not install on circuits exceeding the rated voltage of the device.
