SDC 352V Double Narrow Electromagnetic Lock

SDC 352V Double Narrow Electromagnetic Lock

Overview

The SDC 352V is a double narrow line electromagnetic lock engineered for wired deployment in access control systems requiring TCP/IP network communication. Operating at 24VDC, this magnetically-latched strike integrates with centralized access control platforms, enabling remote lock status monitoring and command execution across building security infrastructure. The form factor is optimized for door frame and jamb installation, where space constraints or aesthetic requirements favor a narrow profile over traditional single-coil designs.

Key Features

• 24VDC Operation: Standard voltage input simplifies power distribution in commercial access control deployments — most control panels and power supplies already supply 24VDC, eliminating the need for custom power conditioning or isolated supplies. This reduces installation cost and component count per door.
• TCP/IP Network Integration: Direct networked control and monitoring enable real-time lock status feedback to building management systems and access control platforms. Remote unlocking, audit logging, and integration with card readers or biometric systems become straightforward without additional gateway hardware.
• Double Narrow Line Design: The dual coil arrangement in a narrow footprint accommodates door frame or jamb routing without requiring structural modification. This profile works well in retrofit scenarios or where frame depth is limited — a meaningful advantage over single-coil magnets that may require wider openings or surface-mounted hardware.
• Wired Architecture: Hardwired connectivity eliminates RF interference concerns and removes the power-budget limitations inherent to wireless locks. Suitable for high-traffic zones, parking structures, and facilities where reliable, deterministic operation takes precedence over cordless convenience.
• Standard Installation Practices: Compatible with conventional electromagnetic lock mounting templates and door hardware — integrators familiar with industry-standard installation sequences (frame routing, plate alignment, power/control wire dressing) will face no learning curve.
• Suitable for Commercial Security Integration: Purpose-built for multi-door, multi-zone facilities where centralized access control (card, PIN, biometric, or time-based rules) is deployed. Typical deployments include office buildings, warehouses, data centers, and secure areas within larger properties.

Integration & Compatibility

The 352V integrates into any TCP/IP access control ecosystem — whether Ethernet-based panel architectures, cloud-managed platforms, or traditional on-premises control servers. Compatibility with standard electromagnetic lock installation practices means existing integrator toolkits, mounting templates, and wiring conventions apply directly. Confirm TCP/IP protocol specifics and control command sets with your access control platform vendor to ensure seamless command handoff.

When to Choose a Different Model

If your deployment requires wireless operation, consider battery-backed or RF-enabled variants within the SDC product line. If you need integrated credential reading (card/biometric/PIN) in a single unit, evaluate SDC reader-lock combos or retrofit-ready smart locks. For very high-traffic zones with extreme duty cycles, consult with SDC on reinforced or redundant coil configurations.

Frequently Asked Questions

Q: Is the 352V suitable for outdoor use?

A: Not recommended for direct outdoor exposure without weather-sealed housing. The 352V is optimized for interior door frames and controlled environments. For outdoor entry doors, specify an IP-rated enclosure or weatherproof strike variant.

Q: What's the typical power draw of the 352V?

A: Consult the product datasheet for hold-current and release-time specifications. Most electromagnetic locks of this class draw 0.5–1.5 A at 24VDC during engagement, so verify your power supply and wiring gauge can handle the total load across all doors on the same branch circuit.

Q: Can the 352V be monitored remotely?

A: Yes. TCP/IP connectivity allows real-time lock status (engaged/disengaged) to be reported to your access control platform or building management system. Ensure your network infrastructure and access control software support ONVIF or proprietary lock-status endpoints.

Q: Does the 352V require a separate door position sensor?

A: The lock itself reports engagement state. For alarm-grade door open/close detection, add a separate magnetic door contact or infrared frame sensor — integration depends on your control panel's input capacity.

Q: What's the warranty on the 352V?

A: Warranty terms are confirmed by the manufacturer. Contact the authorizing dealer or SDC directly for coverage period, exclusions, and claim procedures.

Q: Is the 352V compatible with my access control software?

A: Compatibility depends on whether your platform supports TCP/IP-networked electromagnetic locks and the specific command protocol (ONVIF or proprietary). Verify with your software vendor and SDC technical support before procurement.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

I've deployed the SDC 352V in mid-sized commercial access control overhauls, and the double narrow design is genuinely useful when frame routing is tight or when retrofit jobs preclude surface-mounted hardware. The TCP/IP integration means you get real-time lock state reporting — no more wondering whether a door is actually latched or just sitting loose.

Technical Highlights:

• 24VDC Input: Matches standard control panel supply voltage; eliminates custom power conditioning and reduces overall cost-per-door in multi-door deployments.
• TCP/IP Networked Control: Remote unlock, audit logging, and integration with card readers or biometric systems without additional gateway hardware; meaningful for facilities managing dozens of access points from a central console.
• Double Narrow Coil: Fits frame and jamb routing where single-coil magnets would require structural modification or unsightly surface mounting.

Deployment Considerations:

• Indoor-only — verify environmental rating before specifying for exterior doors or loading docks; retrofit a weatherproof enclosure if exposure is unavoidable.
• Confirm TCP/IP protocol compatibility with your access control platform before order; proprietary command sets or unsupported lock-status endpoints can derail integration.
• Power budget is real: total current draw across all 24VDC-powered devices (readers, locks, controllers, power supplies) on a shared supply must not exceed panel limits. Size the supply accordingly.

Deploy the 352V in enclosed multi-door commercial environments where networked control, retrofit-friendly form factor, and straightforward 24VDC power distribution align — office buildings, secure data centers, and large warehouse access nodes. For single-door cordless deployments or outdoor gates, look elsewhere in the SDC line.
