Overview

• Knight F10CMULTI is a heavy‑duty, potted single‑reed magnetic contact designed for roller shutters and large doors. It features a 1 m armoured lead and built‑in selectable end‑of‑line (EOL) and alarm resistors for fully supervised wiring.
• Suitable for double doors and sheltered external installations; meets typical UK intruder panel supervision requirements (Grade 2 as per manufacturer datasheet).

Key features

• Single reed (normally closed), potted/sealed construction for sheltered outdoor use.
• Integral selectable resistors (EOL and alarm values) — must be used in supervised (EOL) circuits; no 4‑wire option.
• ~50 mm operating gap to tolerate shutter movement.
• 1 m armoured sleeving (stainless steel armour over cores) for robust cable protection.
• Anodised aluminium body with ferrite/Alnico V magnet and rhodium‑plated reed for reliable switching.

Technical & installation notes

• Electrical rating: up to 500 mA (DC or AC); suitable voltage range per datasheet (refer to manufacturer datasheet for panel compatibility).
• Temperature range: −40 °C to +50 °C. Environmental Class III (sheltered external) — not for fully exposed marine/coastal environments unless additional protection provided.
• Designed for fully supervised intruder alarm panels — follow panel manufacturer wiring diagrams when selecting EOL resistor configuration from the 8‑core lead.
• Installation should be performed by a qualified installer; adhere to BS50131 guidance where applicable and confirm any site certification requirements.

What it solves

• Provides a rugged, tamper‑resistant contact for roller shutters and large doors where standard small magnetic contacts are unsuitable.
• Integral resistors simplify supervised wiring and reduce on-site component requirements.

Compliance & disclaimers

• Manufacturer rates product as Grade 2 and references BS50131‑2‑6 compatibility — check local certification requirements for installed systems and request official certification paperwork if needed.
• This description is based on the manufacturer datasheet; installers must consult the datasheet and panel manufacturer documentation for precise wiring and resistor selection.
