Ditek DTK-120X12 Surge Protection Device 120V 12 Low Voltage

Product Description

The DITEK DTK-120X12 is a combination surge protection device designed to protect both 120-volt AC power lines and up to 12 low-voltage circuits simultaneously. It is built for fire alarm and life safety system applications where a single transient voltage surge event can damage multiple circuit types at once. Licensed fire alarm technicians and low-voltage contractors install this device at the panel or equipment level to guard sensitive detection and notification equipment. The DTK-120X12 provides coordinated protection across power and signal circuits in a single unit, reducing installation time and consolidating surge suppression in one location.

This device is used in commercial and light industrial fire alarm system installations where 120-volt power feeds and multiple low-voltage signal or data circuits require simultaneous surge protection. Typical applications include fire alarm control panels, addressable detection systems, and notification appliance circuits. It is well suited for new construction and retrofit installations where code-compliant surge protection is required for life safety equipment.

Key Features

• Protects 120-volt AC power input and up to 12 low-voltage circuits in a single device
• Designed specifically for fire alarm and life safety system surge protection applications
• Combination protection reduces the number of individual suppressors needed at a panel
• Sold as a single unit (EA), suitable for one control panel or equipment enclosure
• Supports installations requiring coordinated AC and low-voltage circuit protection

Compatibility

Designed as an OEM-style surge protection solution for fire alarm control panels and life safety systems utilizing 120-volt AC power with multiple low-voltage signal or data circuit connections.

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 AC power feed and disconnect all low-voltage circuits before making connections. Verify that all circuit terminations are secure and that the device is properly grounded before restoring power. Do not install in locations exposed to moisture unless the enclosure is rated for wet or damp environments.
