Camden CX-ED1579L – 3-Hour Fire-Rated Grade 1 Electric Strike with Latch Monitoring is a heavy-duty electric door strike designed for compatible mortise and cylindrical locksets and professional access-control installations. It combines six stainless-steel faceplates, 12/24V AC/DC field-selectable power, a SPDT latch-monitor output, and up to 3/4-inch latchbolt accommodation in one flexible strike assembly.

Critical fire-rating distinction: the manufacturer specifies a three-hour UL 10C/CAN4-S104 fire rating only in fail-secure mode when used in an appropriately approved opening. The electric strike is field-selectable fail-safe or fail-secure, but fail-safe configuration must not be represented as having that fire rating. Verify that the complete door assembly, door hardware, frame and wiring meet applicable codes and listing conditions.

Technical Specifications

Commercial Applications

Recommended for properly engineered commercial access-control installations, including offices, retail facilities, institutional buildings, service doors, tenant entrances and other security-controlled doors where a door-frame strike can release the door's compatible mechanical latch on command. Works with correctly specified access-control panels, intercom relays, readers, keypads and release-control equipment.

Installation and Ordering Notes

IMPORTANT: The CX-ED1579L's 3-hour fire rating applies only in fail-secure mode and within an approved rated door/frame assembly. Do not claim a fire rating when configured fail safe. Verify the exact mortise/cylindrical lockset, selected faceplate, latch/deadbolt configuration, fire-door listing and AHJ requirements before ordering. Confirm electrical ratings, mounting space, door handing, mechanical latch alignment and all building, accessibility, electrical and fire/egress code requirements. Follow the current Camden installation instructions and ensure installation by qualified personnel. The mechanical lockset, access controller, card reader, power supply, cabling and other accessories are not included unless separately specified.

Fire Door and Latch Monitoring Checklist

The Camden CX-ED1579L is a heavy-duty monitored electric strike for appropriately specified commercial openings. It provides a Grade 1 electric strike with latchbolt monitoring and manufacturer-listed fire-door suitability in the specified fail-secure arrangement.

1. Confirm rating: Review the approved door/frame listing, applicable codes and required installation instructions before using this product on an opening requiring a three-hour fire rating.
2. Confirm operating mode: For fire-rated installations, follow the manufacturer-listed fail-secure requirements; field-selectable lock modes do not override the door's listing.
3. Check latch projection: Measure the installed cylindrical or mortise latch to verify its compatibility with the strike's 3/4-inch projection application.
4. Wire the monitor: Connect the latch-monitor contact to the correct access-control or supervision inputs and confirm contact logic by testing the actual installed latch.
5. Match faceplate and jamb: Select the required faceplate from the six supplied stainless-steel options while preserving required door and frame clearances.
6. Commission: Test normal release, latch monitoring, loss of electrical power, smoke/fire requirements and free egress at the opening.

Typical Projects

Institutional, healthcare, educational and other commercial openings where a heavy-duty Grade 1 electrified strike, supervised latching and an approved fire-door configuration are specified. The complete access system, controller, power supply and locking hardware are not included unless expressly listed.
