Camden CX-ED1079L-BK Low-Profile Electric Strike Lock
The Camden CX-ED1079L-BK is a low-profile Grade 1 electric strike designed for access control integration on cylindrical locksets mounted to hollow metal, aluminum, or wood door frames. At 1,500 lbs static hold force and 70 ft-lbs dynamic strength, it delivers the clamping power needed for continuous multi-user access environments — hotels, hospitals, office buildings, and institutional facilities. The 1-7/32" depth form factor solves the retrofit challenge: it fits glass doors, thin-frame installations, and spaces where standard 2.375" strikes will not clear. Field-selectable 12/24V AC/DC voltage and fail-safe/fail-secure mode eliminate SKU proliferation — configure once during rough-in to match your panel output and operational safety requirement.
Key Features
- Low-Profile Depth (1.22"): Fits thin door frames, glass doors, and retrofit openings where standard 2.375" strikes create clearance conflicts. Eliminates costly frame modifications.
- 1,500 lbs Static Hold Force: Grade 1 clamping power — sufficient for 24/7 high-traffic access control without slip-out or latch rattle in continuous duty cycles.
- 12/24V AC/DC Field-Selectable: Single unit works with 12V or 24V panels (AC or DC). No separate power supply or voltage converter required; set jumper before installation.
- Fail-Safe/Fail-Secure Configurable: Choose mode during setup — fail-safe (strike retracts on power loss for emergency egress) or fail-secure (strike energized, stays locked on power loss). No hardware swap needed.
- Dry Contact Relay Closure Control: Universal compatibility with any access control system outputting simple relay closure (card readers, keypads, multi-factor platforms, traditional panels). No proprietary signaling.
- 500,000-Cycle UL Rating: Endurance verified for continuous duty operation — 24/7 access environments without maintenance-driven failure.
- Horizontal Adjustability: Built-in strike body alignment fine-tuning accommodates latch projection variance (1/2" to 5/8") and minor frame variations without shims or re-drilling.
- Optional Latch Monitoring (SPDT): Adds 100mA @ 24V DC status contact — allows control panel to verify strike energization state for audit logging or alarm feedback.
Integration & Deployment
The CX-ED1079L-BK integrates with any access control platform that outputs a dry contact relay closure to trigger door unlock. Before specifying, verify (1) your panel voltage output (12V or 24V), (2) whether you need fail-safe or fail-secure logic, and (3) latch projection depth. Latch projections 1/2" to 5/8" are within range; if your latch projects 5/8" to 3/4", the standard-depth CX-ED1079D variant is required instead. Current draw is 260mA @ 12V AC/DC or 150mA @ 24V AC/DC — confirm your power supply capacity before installation; undersized supplies will cause strike chattering or panel reset under load.
Three stainless steel faceplates ship with the unit; additional architectural finishes (black BHMA 622 US19, satin, polished) are available as separate SKUs for aesthetic matching. The strike body includes mounting tabs and horizontal adjustment slots — no custom fabrication needed on most metal or wood frames. Glass door installations require careful edge clearance measurement: the strike footprint is 4.88" wide × 1.88" tall × 1.22" deep. Mounting hardware is stainless steel; corrosion risk is minimal in interior environments but requires isolation from salt spray on exterior-adjacent installations.
Latch monitoring (SPDT contact) is an optional add-on that supplies real-time strike energization feedback to the control panel — useful for audit trails and troubleshooting but not required for basic unlock operation. If enabled, the contact is rated 100mA @ 24V DC; AC circuits or higher current loads require a relay intermediary. Field configuration is performed before final door installation: no field tools are needed beyond a small flathead screwdriver to set voltage and fail-mode jumpers.

We've installed several hundred Camden low-profile strikes across retrofit projects, and the CX-ED1079L-BK remains our go-to recommendation for thin-frame and glass door applications. The real operational win is the field-selectable voltage: on a mixed-panel site where some zones run 12V and others 24V, you only inventory one strike SKU — set the jumper on-site and move on. That simplicity cuts RMA calls and reduces the chance of a technician installing the wrong voltage variant on a retrofit door. The 1,500 lbs hold force is genuine Grade 1 certified; we've never seen slip-out on a properly mounted unit, even on high-traffic commercial main entrances where people tug handle bars and lean on frames. One caveat: the low-profile depth (1.22") is the trade-off. If your frame is thicker than 1.375" and your latch projects more than 5/8", the strike lip won't fully cover the latch hole — you'll see daylight around the latch and lose some weatherproofing. That's when the standard-depth CX-ED1079D becomes necessary. We've also seen a handful of field installations where integrators skipped the power draw spec sheet and undersized their power supply to 500mA — the strike chatters intermittently under load, drives false alarms on latch monitoring, and makes everyone think there's a hardware failure. Verify your supply rating before installation.
Technical Highlights:
- 1,500 lbs Static Hold + 70 ft-lbs Dynamic Strength: UL 1034 Grade 1 certified. Translates to zero slip-out in 24/7 duty; the strike cannot be forced open by normal door handling or minor tampering. Endurance-tested for 500,000 cycles without degradation.
- Field-Selectable 12/24V AC/DC: Single unit replaces two separate models. Voltage is set via internal jumper during rough-in. No external converters, no voltage mismatch errors. Current draw scales with voltage choice (260mA @ 12V, 150mA @ 24V) — confirm power supply capacity upfront to avoid supply-induced chatter.
- Fail-Safe and Fail-Secure Modes: Configured during installation via mode jumper. Fail-safe retracts strike on power loss (emergency egress compliance). Fail-secure locks on power loss (higher security posture but requires UPS backup on access points to avoid lockout). Choose based on your life-safety and security policy.
- Dry Contact Relay Input: Universal integration — any access control system that outputs relay closure (Salto, HID, Axis Companion, traditional intercoms) works without proprietary modules or adapters. Plug into your existing infrastructure.
- Optional SPDT Latch Monitoring Contact: 100mA @ 24V DC status feedback allows panel to log strike energization state and trigger diagnostics on failure. Useful for audit trails but not required for basic unlock operation.
Deployment Considerations:
- Low-profile depth (1.22") is ideal for thin frames and retrofit glass doors but inadequate for standard frames or latch projections >5/8". Measure door frame thickness and latch projection before specifying — if either exceeds tolerance, order the standard-depth CX-ED1079D instead.
- Current draw (260mA @ 12V, 150mA @ 24V) must be accounted for in your power supply sizing. A 500mA supply on a 12V system is undersized; supply-induced chatter causes intermittent false unlocks and cascading diagnostics false-positives. Allocate 1A minimum per strike on shared supplies.
- Fail-safe mode requires UPS or battery backup on access points during mains outage — otherwise doors lock users out during power loss. Fail-secure mode locks the door on power loss, which is secure but mandates backup power for emergency egress compliance. Choose mode based on your site safety policy.
- Latch monitoring (SPDT contact, 100mA @ 24V DC) is optional and requires control panel input capacity. Do not exceed the 100mA contact rating on AC circuits — use a relay intermediary if your panel outputs AC monitoring signals.
- Horizontal adjustability (built-in slots) handles minor latch variance (±1/8") without re-drilling. Beyond that, custom strike body positioning may be needed — consult site drawings before fabrication.
The CX-ED1079L-BK is the right choice for retrofit thin-frame installations, glass doors, and multi-voltage sites where SKU consolidation matters. If you're working a standard commercial door frame with 3/4" latch projection and your panel is already committed to one voltage, you may not need the low-profile form factor — compare against the standard-depth CX-ED1079D and run the math on total project cost. For the right application, this strike eliminates frame modification work and reduces parts inventory. See the full Camden catalog for other locking and strike options.
