Alarm Controls 1200WP US28 Weatherproof Magnetic Lock — 1,200 lb Holding Force for Gates & Perimeter Access Control

The Alarm Controls 1200WP is a heavy-duty, weatherproof electromagnetic gate lock engineered for demanding perimeter access control applications. Delivering 1,200 lbs of holding force in a fully sealed stainless steel housing, it is purpose-built for exterior sliding and swinging gates where exposure to moisture, dust, and temperature extremes would compromise standard interior maglocks. The US28 (clear anodized) finish provides a clean, corrosion-resistant appearance suited to aluminum gate frames and architectural metalwork.

Key Features & Benefits

• 1,200 lb holding force — robust electromagnetic retention for single-door perimeter gates
• Fully weatherproof construction — completely sealed in a stainless steel case; non-aluminum components are plated for corrosion resistance, rated for outdoor use from +14°F to +131°F (−10°C to +55°C)
• Dual-voltage operation — field configurable for 12 VDC or 24 VDC systems; current draw is 500 mA at 12 VDC / 250 mA at 24 VDC
• Flexible mounting — top mount or side mount via L-brackets (ordered separately); compatible with sliding or swinging gate configurations
• Conduit-ready wiring — 0.5" ID / 0.75" OD conduit fitting pipe thread; 10" color-coded wire leads in plastic jacket for clean, weather-protected wiring runs
• Installer-friendly hardware included — blind nuts and self-drilling TEC screws provided
• US28 clear anodized finish standard — matches aluminum gate and storefront framing
• Limited lifetime warranty

Ideal Applications

• Perimeter security gates — parking facilities, loading docks, utility yards, campus access points
• Sliding and swinging aluminum or steel gates in exterior access control systems
• Outdoor access-controlled entry points integrated with card readers, keypads, or intercom systems
• Locations requiring fail-safe (power-to-lock) electromagnetic access control in wet or harsh environments

Code & Integration Notes

Electromagnetic locks are fail-safe devices — the door or gate releases upon loss of power. When installed on pedestrian egress paths, applicable codes (IBC 1010.1.9.9 / NFPA 101 §7.2.1.5.6) require that the lock be released by listed hardware with a built-in switch, a sensor-actuated push-to-exit button, or integration with the fire alarm system so the lock releases automatically upon alarm activation. Consult your local Authority Having Jurisdiction (AHJ) and a qualified access control integrator to confirm compliant wiring and egress provisions for your specific installation. This lock is designed for gate applications — verify egress requirements with your project's code professional where pedestrian traffic is involved.
