Knight Fire & Security PDD704K7 – G2 6-Terminal Industrial Surface Contact – Single Reed 4K7/4K7

Full Description

Knight Fire Grade 2 6-Terminal Industrial Surface Contact

The Knight Fire & Security PDD704K7 is a high-performance industrial surface contact designed to meet Grade 2 security standards. Featuring a single reed switch and built-in 4K7 resistors for both alarm and end-of-line (EOL) configurations, this contact ensures reliable operation in high-security environments.

Designed for use with Aritech and HKC panels, the PDD704K7 provides versatile wiring options, allowing it to function as an end-of-line (EOL) contact or within a shared zone setup. Its 6-terminal design offers easy installation and flexible integration, while the 40mm operating gap enhances performance in industrial applications.

Built from high-impact polystyrene, this contact is durable and robust, meeting EN50131-2-6 compliance for reliable security performance. Available in white (PDD704K7) and brown (PDD704K7B), it is suitable for various security system installations.

Key Features & Benefits:

• Security Grade 2 Certified – Meets EN50131-2-6: 2008 standards for industrial security applications.
• Built-In 4K7 Resistors – Includes 4K7 resistor for alarm and 4K7 resistor for EOL, ensuring seamless integration with Aritech and HKC panels.
• 6-Terminal Design for Flexible Wiring:
