Camden Mortise cylinder housing for Best™ style IC core

We've specified the CM-307 across institutional and corporate campuses where Best IC standardization was already locked in by the facility master specification. The real operational win isn't the housing itself—it's the ecosystem. Once you commit to Best IC format across 100+ doors, credential lifecycle becomes trivial. A terminated employee's access is revoked by swapping a cylinder in 30 seconds, no locksmith callout, no re-keying overhead. That's worth the upfront investment in standardized hardware. On a 500-door healthcare network, we've seen credential rotation labor drop by 60-70% just by moving to IC format. The CM-307 is the physical anchor point for that strategy. Pair it with a HID access control backbone, and you have a credentialing system that scales without added complexity.

The 30VDC strike is not exotic—it's table-stakes for any modern commercial electromagnetic lock panel. Every access control vendor supports 30VDC natively. The housing itself is passive; all the intelligence lives in the strike controller and the HID credential platform. What matters is that the housing doesn't create a bottleneck. It seats, it accepts cores, it passes strike voltage reliably, and it stays out of the way.

Technical Highlights:

• Best IC Cylinder Acceptance: The housing is milled to Best IC tolerance, meaning any authorized Best core from any licensed manufacturer will seat and function. This vendor-independence is critical on multi-year projects where supply chains shift.
• 30VDC Strike Integration: Standard electromagnetic lock voltage across the industry. Your strike controller and UPS backup power infrastructure are already designed around this; no custom power supply engineering needed.
• Mortise Form Factor: The housing mounts in standard 2-1/8", 2-3/4", and similar mortise lock cavities prepared to Best specification. Zero re-boring of door frames required if you're replacing older Best hardware or new-constructing to Best standard.
• HID Ecosystem Fit: HID credential platforms (card readers, mobile, biometric) all natively integrate with Best IC hardware via standard strike controllers. The CM-307 is a pass-through—no proprietary APIs or custom firmware.
• Credential Swap Speed: Core changeover in 20-40 seconds, no tools required beyond a hex key for the set screw. In a 100-door facility with monthly access reviews, this saves hundreds of labor hours per year.
• Audit Trail Coupling: When the CM-307 housing is connected to a HID-managed strike controller, every credential event (access granted, denied, revoked) is logged. Physical and digital trails align—critical for SOX/HIPAA compliance.

Deployment Considerations:

• Best IC cores are NOT included—order them separately from Best or authorized resellers. The housing is the mounting frame only. Verify core availability and lead times before committing the door prep.
• 30VDC power must be sourced from a strike controller or access control panel rated for electromagnetic lock duty. If your facility is running older 12VDC strike systems, you'll need panel upgrades—budget for that before installation.
• The housing mounts only in mortise cavities prepared to Best IC standard. If your doors are prepped for Schlage IC or ASSA ABLOY IC, the CM-307 will not fit. Verify the existing lock body format before design; this is a no-return item if the cavity is wrong.
• Interchangeable cores come in multiple depths (6-pin, 7-pin, variants) and keyways (standard, restricted). Specify the correct core profile at purchase time. A 7-pin core will not seat in a 6-pin housing.
• The housing is a passive component—it has no electronics, no firmware, no network connectivity. All access control logic lives upstream in the strike controller and HID platform. Commissioning is wiring and core seating; no software patches.

The CM-307 is ideal for facilities with large lock schedules, high credential rotation, or multi-tenant environments where Best IC standardization is already a facility standard or a strategic direction. If you're building a new campus and designing the lock schedule from scratch, Best IC (with the CM-307 as the housing anchor) is a mature, low-risk choice.
