DITEK Releases Surge Protection Solution for Fire Alarm Systems

LARGO, Fla. — DITEK announces the launch of a new complete electrical surge protection solution for fire alarm systems.

The DTK-120X12 is said to combine protection for 120V system power with protection for up to 12 low voltage circuits to eliminate damage caused by electrical surge events.

This new combination simplifies implementation of comprehensive surge protection for critically important fire alarm systems while providing for remote monitoring of surge protection status using dry contacts, according to the company.

The modular plug-in design simplifies installation of surge protection modules and allows for easy replacement when needed.

“The new DTK-120X12 brings together a simple and complete solution for fire alarm systems,” says Michael Molinari, director of marketing, DITEK. “By expanding protection beyond the primary power supply to the low voltage signaling and control circuits, this new protection solution drastically reduces the chances that these wires can carry destructive surges back into the fire control panel. There is no better way to quickly protect a fire alarm system.”

The DTK-120X12 base is designed to be wall-mounted and hardwired, and includes the 120VAC power surge protection unit with dry contacts for remote monitoring of surge protection status.

The 120VAC module also has LEDs for visual confirmation of status, as well as a loud audible alarm that sounds if protection has been compromised. This three-way notification is designed to ensure that the system will not remain unprotected, according to the company.

The base also has space for mounting up to six compatible low voltage protection modules (DTK-2MHLP and/or DTK-2MHTP) that can be used to protect up to 12 SLC, NAC, IDC, PIV, and dialer circuit pairs (these modules must be ordered separately to match the needs of the installation). All the protection modules are field-replaceable. A sliding cover is provided to prevent accidental contact.

The DTK-120X12 is UL 1449 listed as a Type 2 SPD and UL 497B for surge protection, UL 1283 listed for EMI/RFI noise filtering, and complies with applicable IEEE standards. The DTK-120X12 is made in the USA, with a 10-year limited warranty.
