Ditek DTK-DF120M Replaceable Surge Deflector 120V

Product Description

The DITEK DTK-DF120M is a replaceable surge deflector module rated for 120-volt applications in fire protection systems. Designed as a modular, field-replaceable component, this deflector absorbs and diverts transient voltage surges that can damage sensitive fire alarm control panels and associated equipment. When a surge event occurs, the module takes the hit so the connected equipment does not. The replaceable design means a technician can swap out the sacrificial module after a surge event without replacing the entire surge protective device assembly, reducing downtime and service cost.

This module is suited for fire alarm system installations in residential and commercial buildings where surge protection is required at the panel or device level. It is typically installed by licensed fire alarm technicians or electricians working on life-safety systems. Applications include fire alarm control unit circuits and low-voltage signaling lines operating at 120 volts where transient protection is specified by the engineer of record or required by local authority having jurisdiction.

Key Features

• Replaceable modular design allows field swap-out after a surge event without full device replacement
• Rated for 120-volt fire protection system circuits

Installation Notes

Installation and replacement should be performed by a licensed electrician or qualified fire alarm technician in accordance with NFPA 72, the NEC, and all applicable local codes. De-energize the circuit and follow proper lockout/tagout procedures before removing or inserting the module. Verify the replacement module voltage rating matches the circuit before reinstalling. Life-safety system work may require inspection or approval by the authority having jurisdiction.
