Ditek DTK-DR24B Din Rail Surge Protector 24V 2-pair

Product Description

The DITEK DTK-DR24B is a DIN rail-mounted surge protector designed for 24-volt, 2-pair low-voltage signal and power circuits commonly found in fire alarm systems. It provides transient voltage surge suppression (TVSS) for sensitive control wiring, clamping voltage spikes caused by lightning, inductive switching, and other electrical transients before they reach connected devices. The DTK-DR24B mounts directly on standard DIN rail, keeping panel installations organized and accessible. Fire alarm technicians and low-voltage control specialists are the primary installers of this device.

This surge protector is suited for fire alarm panels, notification circuits, and related 24-volt low-voltage wiring in both commercial and residential applications. It is typically installed in electrical or fire alarm control panels where DIN rail mounting is standard. The 2-pair configuration makes it appropriate for protecting two discrete wire pairs simultaneously, covering both signal and return conductors in a single device footprint.

Key Features

• DIN rail mount design for clean, organized panel installation
• Protects 24-volt, 2-pair low-voltage circuits from transient voltage surges
• Designed for fire alarm surge protection applications
• Compact form factor suited for crowded control panel environments
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style DIN rail surge protection device for 24-volt, 2-pair fire alarm signal and control circuits in commercial and residential fire alarm panel installations.

Installation Notes

Installation should be performed by a licensed low-voltage or fire alarm technician in accordance with NFPA 72 and applicable local codes. De-energize the fire alarm control panel before connecting or disconnecting any surge protection device. Verify that the circuit voltage matches the 24-volt rating of the DTK-DR24B before installation. Consult the manufacturer data sheet for terminal wiring layout and grounding requirements.
