Knight XE90A-1KR Grade 3 Mini Aluminium Surface Magnetic Contact
The Knight XE90A-1KR Grade 3 Mini Aluminium Surface Contact is a professional magnetic door contact designed for high-security intruder alarm installations requiring dependable door monitoring and magnetic interference detection.
Manufactured with a compact, durable aluminium housing, this surface-mounted contact provides a discreet and reliable solution for compatible intruder alarm installations.
Grade 3 Security Protection
Designed to comply with EN 50131-2-6 Grade 3, the XE90A-1KR incorporates magnetic bias technology designed to detect interference from external magnets.
This makes it suitable for professionally designed Grade 3 intruder alarm systems where enhanced security monitoring and protection against magnetic interference are required.
Integrated 1K/1K Resistors
The contact features factory-integrated resistors:
- 1KΩ alarm resistor
- 1KΩ end-of-line (EOL) resistor
These resistor values support compatible supervised alarm circuits, including suitable Honeywell Galaxy and Ademco control panels.
Always verify resistor compatibility with the alarm panel’s zone configuration before installation.
Compact and Durable Aluminium Construction
The robust aluminium housing measures just 40 × 14 × 9.7 mm, making the XE90A-1KR suitable for applications where a compact, surface-mounted magnetic contact is preferred.
Its pre-wired 1-metre, 6-core cable provides a convenient connection to compatible intruder alarm control equipment.
