Ditek DTK-VM4512 12V Surge Protection Module

Product Description

The DITEK DTK-VM4512 is a single-channel surge protection module rated for 12-volt DC systems. It is designed to protect sensitive low-voltage fire alarm and life safety circuits from transient voltage events, including lightning-induced surges and switching transients. Installed inline on a single signal or power channel, this module clamps damaging voltage spikes before they can reach connected panel components or field devices. Licensed fire alarm technicians and low-voltage electricians install this type of module during new system construction and as a protective upgrade on existing panels.

The DTK-VM4512 is suited for use in fire alarm and life safety system installations where 12-volt DC circuits require surge protection. Typical applications include protecting initiating device circuits, notification appliance circuits, and auxiliary power outputs on fire alarm control panels operating at 12 volts DC. It is categorized under fire surge protection, making it a standard selection for commercial and residential fire system service work.

Key Features

• Single-channel design protects one 12-volt DC circuit per module
• Rated for fire alarm and life safety surge protection applications
• Sold individually as a single unit for targeted circuit protection
• Compact module format for integration into existing panel enclosures
• Designed to suppress transient voltage events on low-voltage DC circuits

Compatibility

Designed as an OEM-style surge protection module for single-channel 12-volt DC circuits in fire alarm and life safety system installations.

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 fire alarm panel and notify the monitoring center before beginning any wiring work. The module should be installed as close to the protected equipment as practical. Follow the manufacturer wiring diagram for correct polarity on DC circuits.
