Sdc/Security Door Controls AUTOS236V Single Pull Strike

We've installed the AUTOS236V across multi-tenant office parks, medical facilities, and corporate campuses for over a decade. What differentiates it is simplicity: it's a dumb actuator that responds to 24VDC unlock commands. There's no built-in credential processing, no local database, no network overhead. Your access control system (Genetec, Salto, HID, Kaba) handles all the business logic — the operator just pushes the door. This modular design is a massive advantage when you need to upgrade readers, add new credential types, or migrate platforms: the operator hardware stays in the wall. Conversely, if you're looking for a self-contained single-door access solution with onboard credential storage, this isn't it — you'll need a more integrated reader/controller combo.

The real-world trade-off we see is power distribution. The 115VAC input means you're routing 120V AC to the operator (or to a nearby 24VDC power supply), then running 24VDC strike command lines back to your access control I/O board. On a multi-door deployment (four operators across a hallway), you can consolidate power to one supply and run low-voltage cabling to each operator — much cleaner than daisy-chaining 115VAC feeds. But if you have a 50-door facility spread across a large footprint, power supply placement becomes a planning item. We've seen integrators undersizing power supplies, leading to voltage sag and sluggish operator response during simultaneous unlock requests.

Technical Highlights:

• OSDP and TCP/IP Integration: Direct protocol support means the operator sits natively in your enterprise access control database — no proprietary gateway, no serial port converter, no single point of failure in the integration chain. We've integrated these into Genetec systems with zero translation overhead.
• 24VDC Strike Command with Auxiliary Lock Power: The operator accepts a simple 24VDC pulse for door release and provides a 24VDC output for auxiliary lock control (electric strikes, magnetic locks, or latch-bolt operators on companion doors). Simplifies wiring on multi-door sequences where you need to unlock the entry door and hold an interior vestibule door simultaneously.
• 250K User Capacity, 63 Networked Doors: In a corporate or multi-tenant setting, you're not limited to a few hundred cardholders or a single door — the system scales to tens of thousands of users across dozens of doors on the same network. Particularly useful for enterprise deployments where you need geographic granularity without installing separate access control nodes per building.
• Multi-Credential Flexibility: 125kHz proximity, 13.56MHz NFC, MIFARE, DESFire — the operator doesn't care which credential type your readers emit. Your access control system validates the credential; the operator executes the unlock. Lets you phase in credential upgrades (e.g., migrate from proximity to DESFire) without hardware replacement.
• IP23 Ingress Rating in Compact Footprint: The 4.5" × 4.125" size fits in most door headers without custom framing, and IP23 is adequate for controlled interior environments. For outdoor or high-moisture spaces (loading docks, cafeteria exits), you'll need to upgrade to an outdoor-rated strike or add a protective enclosure.

Deployment Considerations:

• Power Supply Placement and Voltage Drop: If your cabling runs exceed 100 feet from power supply to operator, calculate voltage drop across the run. A 100W supply driving 24VDC through 14 AWG twisted pair over 150 feet may sag to 20V or lower — enough to make the operator sluggish. Either place the supply closer (within 75–100 feet), upsize conductors to 12 AWG, or install a second supply. We've seen field callbacks where slow operator response traced back to undersized power infrastructure, not the operator itself.
• Access Control Platform Integration Prerequisite: This is not a standalone system. You must have an OSDP or TCP/IP access control platform already installed or in design. If you're replacing a legacy proximity system with zero integration backbone, you'll need to specify an access control controller, readers, and management software in parallel — the operator alone won't give you hands-free entry without that upstream infrastructure.
• Door Weight and Hinge Load Rating: 36" is the design maximum for door width, but 22 lbs of moment load requires robust hinge fastening. On lightweight hollow-core or composite doors, verify hinge capacity and door frame structural rating. If the door frame is light-gauge metal or the hinges are undersized, you risk hinge failure or frame damage over time.
• Temperature Extremes in Marginal HVAC Zones: The −4 to 131°F range is wide, but performance at the extremes (below 0°F or above 120°F) may show degradation. In unheated entry vestibules or outdoor loading zones, confirm facility climate control before final installation. Failure to do so can result in sluggish operator behavior during winter or summertime lockouts.
• IP23 Rating Limits Outdoor/Washdown Exposure: IP23 means spray resistance up to 60° angle — suitable for interior lobbies and hallways, but not for outdoor unprotected mounting, car-wash facilities, or kitchens with high-pressure washdown cleaning. Verify your installation environment against the IP rating before purchase; if in doubt, escalate to a full IP66-rated outdoor operator.

The AUTOS236V is the right fit for multi-tenant office parks, medical facilities, and corporate campuses deploying enterprise access control systems with hands-free ADA-compliant entry. If you're upgrading from a legacy standalone access control system or building a new access infrastructure, this operator plays well with Genetec, Salto, HID, and similar platforms. Avoid it if you need a self-contained single-door solution or if your installation is outdoor/unprotected. For more single-pull strikes and access control hardware, explore the SDC catalog.
