HES 1200WP Electromagnetic Lock Weatherproof
The HES 1200WP is an electromagnetic access control lock engineered for reliable fail-secure operation in demanding indoor and outdoor environments. Unlike standard indoor magnetic locks, the 1200WP combines weatherproof sealed housing with solenoid robustness to handle rain, salt spray, dust, and freeze-thaw cycles — critical capabilities when deploying locks on exterior doors, loading docks, vehicle gates, or covered outdoor areas. Fail-secure operation means the lock remains engaged during power loss or reader downtime, ensuring no unintended access when system reliability is compromised.
Key Features
- Fail-secure electromagnetic mechanism: Lock holds the door closed during power loss or access control system outage. The solenoid disengages only when powered, so loss of 12VDC or 24VDC supply leaves the door locked — appropriate for high-security perimeter points, but verify fail-secure behavior aligns with your local fire code and emergency egress rules before installation.
- Weatherproof sealed housing: Enclosure resists rain, salt spray, dust, and environmental contaminants that would corrode or jam standard indoor locks within months. Extended service life in outdoor installations reduces maintenance callbacks and unplanned downtime on critical access points.
- Compact profile for glass doors: The 1200WP fits into standard single and double glass door frames without requiring frame modification, structural reinforcement, or custom carpentry. Drop-in compatibility reduces installation labor and allows retrofit on existing facilities.
- Low power consumption: Draws minimal current at standard 12VDC or 24VDC control voltage, reducing load on your access control power supply. Lower draw allows extended hold time on battery backup during facility power outages — meaningful when access control must remain responsive during emergencies.
- Fast solenoid response: Quick engagement and release cycles support high-traffic facility requirements. Doorways with dozens of authorized entries per hour experience no lag or mechanical fatigue from repeated operation.
- Standard voltage compatibility: Works with common 12VDC and 24VDC access control outputs — the voltages already present on most hardwired door access control panels and cloud-based smart readers. No specialized power conditioning, no voltage converters, no rewiring of reader circuits. Integrates as a simple 2-wire solenoid load into existing access control system infrastructure.
Integration & Compatibility
The 1200WP pairs with any standard electromagnetic lock controller or access control panel that can supply voltage and ground to trigger the solenoid. Works across hardwired door access control architectures, cloud-based smart readers, and legacy wired intercom systems — no proprietary modules or special drivers required. Suitable for commercial buildings, educational facilities, healthcare institutions, industrial sites, retail environments, and secure perimeter installations where outdoor exposure or harsh environmental conditions rule out traditional indoor magnetic locks.
Deployment Notes
The fail-secure design means the lock will hold the door closed if power is lost — appropriate for high-security applications but verify this behavior aligns with your fire code and emergency egress requirements before deployment. Weatherproof rating handles rain and dust in covered or semi-exposed installations, but sustained submersion or direct high-pressure washing will compromise the seal over time. Install the 1200WP under a soffit or covered canopy if possible. Temperature fluctuations across -40°C to 60°C are supported; verify your mounting surface will not introduce binding or mechanical stress during freeze-thaw cycles common to northern climates. When wiring outdoor, use conduit and waterproof connectors to protect the 12VDC or 24VDC supply line feeding the solenoid.
Frequently Asked Questions
Q: Is the HES 1200WP fail-safe or fail-secure?
A: The 1200WP is fail-secure — it remains locked during power loss. The door stays closed and secured until power is restored to the solenoid. This is the opposite of fail-safe (which unlocks on power loss). Verify fail-secure behavior meets your fire code and emergency egress requirements before installation.
Q: Can the HES 1200WP be installed outdoors?
A: Yes. The weatherproof sealed housing protects internal solenoid and latch components from rain, salt spray, dust, and freeze-thaw cycles. However, sustained submersion or direct high-pressure washing will compromise the seal over time. Install under a soffit or covered canopy if possible to extend service life.
Q: What voltage does the 1200WP require?
A: The 1200WP operates on standard 12VDC or 24VDC control voltage — the same voltages supplied by most access control panels and hardwired door readers. No special power conditioning or converters are required. Integrates as a simple 2-wire solenoid load.
Q: What is the operating temperature range?
A: The 1200WP is rated for -40°C to 60°C (-40°F to 140°F). Verify your mounting surface will not introduce binding or mechanical stress during freeze-thaw cycles in cold climates. Weatherproof sealing protects against moisture damage across this full range.
Q: Does the 1200WP require a dedicated power supply, or can it share with other access control devices?
A: The 1200WP draws minimal current and integrates as a 2-wire load on your existing access control power output. Its low power consumption allows it to share standard 12VDC or 24VDC supplies without straining the panel's capacity. Confirm your access control panel's available current capacity before installation.
Q: How do I integrate the 1200WP into my access control system?
A: Wire the solenoid leads (positive and ground) to the relay output or solenoid port on your access control panel or electromagnetic lock controller. The 1200WP engages when power is applied and disengages when power is removed. No special drivers, no proprietary modules — standard 12VDC or 24VDC control.

The HES 1200WP addresses a real pain point: standard indoor magnetic locks corrode, jam, or fail within months when exposed to outdoor elements. The 1200WP's sealed housing and fail-secure solenoid mechanism eliminate that risk for perimeter access points and covered outdoor areas where weather is a constant threat. The -40°C to 60°C operating range is the key differentiator here — freeze-thaw cycles will bind or crack unsealed locks, but the 1200WP handles both extremes without mechanical drift or seal failure.
Technical Highlights:
- Fail-secure solenoid design: Lock remains engaged during power loss or access control system outage. This is non-negotiable for high-security perimeter points, but verify compliance with local fire and emergency egress codes before installation — fail-secure behavior means the door will not unlock during a fire alarm if the system loses power.
- IP-rated sealed housing: Weatherproof enclosure resists rain, salt spray, dust, and environmental contaminants. Service life in outdoor installations is measured in years, not months — a significant cost and availability advantage over non-sealed locks.
- 12VDC / 24VDC standard voltage: No specialized power conditioning or converters required. Integrates directly into existing access control panel outputs, reducing wiring complexity and commissioning time on retrofit or new deployments.
Deployment Considerations:
- Fail-secure behavior is a feature for security, a constraint for life safety — coordinate fire code compliance before final sign-off. Emergency responders may not be able to force open a powered-down secured door without manual unlock intervention.
- Weatherproof sealing is rated for rain and dust in covered installations. Sustained submersion or high-pressure washing (e.g., dock cleaning) will degrade the seal — mount under soffit or canopy if exposed to heavy spray or standing water.
- Freeze-thaw cycles in northern climates require mounting surface verification. Metal or concrete substrates can introduce binding stress; ensure the mounting frame allows solenoid travel without friction as materials expand and contract.
The 1200WP is the right choice for vehicle gates, exterior roll-up doors, high-security perimeter gates, and warehouse loading dock access where weather resistance and fail-secure behavior are non-negotiable. For interior office or retail glass doors, a standard indoor fail-safe lock is more appropriate and fire-code-friendly.
