Nascom Surface Mount Man Door Contact N505AS/ST for Aluminum/Steel Doors, 2.13" Gap, 24" Armored Cable, Silver

The Nascom N505AS/ST is a surface-mount switch and magnet set for man doors (personnel doors) made of aluminum or steel. Built from extruded anodized aluminum with armored cable lead protection, it is intended for commercial installations where a rugged, exposed-mount contact is required and recessing is not practical.

Key Features

• Surface mount for man doors – Mounts on the face of the door and frame, ideal for metal personnel doors that cannot be drilled for recessed contacts.
• NO DEAD SPOT technology – Nascom's NO DEAD SPOT design is built to give consistent detection across the magnet's travel.
• 24" armored cable lead protection – The first 24" of the wire leads run through armored cable to help protect them from tampering and physical damage.
• Extruded anodized (Type II) aluminum – Switch and magnet housings are extruded aluminum with a Type II anodized finish for durability in commercial settings.
• 36" 22 AWG wire leads – Long pre-attached leads simplify routing to the alarm wiring.
• Listed to UL634 – Listed to the UL634 standard for connectors and switches used with burglar-alarm systems.
