The DITEK DTK-S50B is a system-level surge protector designed for intercom and communication wiring applications. It provides transient voltage protection at the point of connection, helping to prevent damage to intercom system components from voltage spikes caused by lightning, switching transients, or induced surges on low-voltage signal lines. The DTK-S50B is sold as a single unit and is installed by licensed low-voltage or alarm technicians as part of a complete surge protection strategy for communication infrastructure.
The DTK-S50B is suited for residential and light commercial intercom installations where signal line protection is required. It is installed in-line on the communication conductors between the intercom panel and field devices. Typical applications include door intercom systems, entry control wiring, and similar low-voltage communication circuits that require surge protection at the equipment interface.
Designed as an OEM-style surge protection device for use with intercom and low-voltage communication system wiring in residential and commercial installations.
Installation should be performed by a qualified low-voltage technician in accordance with applicable NEC requirements for signal and communication circuits. De-energize the intercom system and associated power supplies before connecting or disconnecting the DTK-S50B. Ensure the device is properly bonded to the building grounding electrode system for effective surge diversion. Do not install on circuits exceeding the device's rated voltage and current parameters.
