Ditek DTK-120SRD Hardwired Hybrid Surge Protector

Product Description

The DITEK DTK-120SRD is a hardwired hybrid surge protective device designed for fire alarm and life-safety system applications. It combines hybrid surge suppression technology with a dry contact output, allowing the device to signal a supervisory condition when the surge protection module requires service or replacement. Rated at 120 volts and 20 amps, this unit installs directly into the circuit wiring of fire alarm control panels and associated equipment. Licensed fire alarm technicians and electricians are the primary installers of this device.

The DTK-120SRD is intended for use in fire surge protection applications where maintaining circuit integrity is critical. The dry contact output integrates with fire alarm control panels to provide supervisory monitoring of the surge protector status. This makes it well suited for commercial and institutional fire alarm installations where code compliance and continuous system supervision are required. It is sold as a single unit.
