Camden CX-EPD1289L – Grade 1 Preload-Resistant 3/4" Surface-Mount RIM Electric Strike with Latch Monitor provides controlled entry through compatible rim exit devices with 3/4-inch Pullman latches. Built for commercial access-control and security installations, this patented, heavy-duty electric strike is engineered to release reliably even when a door places up to 15 lb of preload pressure on the keeper. This makes it an attractive choice for high-traffic entrances, doors subject to air-pressure differences, and retrofit installations where a conventional strike may bind.

It supports 12 or 24V AC/DC, selectable fail-safe or fail-secure operation, a removable SPDT latch-monitor switch, and stainless-steel construction. Its no-cut, surface-mount design, non-handed operation and included metal mounting jig streamline suitable new or replacement installations. The manufacturer specifies a three-hour fire rating in fail-secure mode only when used in an appropriately listed door assembly.

Key Features & Benefits

• Preload-resistant release: Patented keeper design operates with up to 15 lb of door pressure, helping mitigate problems caused by misalignment, wind/air pressure or other preload conditions.
• Rim exit device compatibility: Designed for 3/4 in. projection Pullman latches used in compatible rim panic and exit devices.
• Grade 1 security: ANSI/BHMA A156.31 Grade 1 certified with 1,500 lb UL-verified static strength.
• Surface-mount no-cut installation: Compact surface-mounted design avoids cutting a strike pocket in correctly prepared frames.
• Selectable power and failure mode: Supports 12/24V AC/DC and field-configurable fail-safe or fail-secure operation.
• Fire-rated installation option: Up to a three-hour fire rating when configured FAIL SECURE and installed in a qualifying approved door assembly; not fire-rated in fail-safe mode.
• Latch status output: Removable plug-in SPDT latch-monitoring switch supplies a monitoring contact for compatible access-control systems.
• Strong stainless-steel construction: Heavy-duty construction for high-use institutional and commercial applications.
• Installer adjustment: Horizontal adjustment and included metal mounting jig assist with positioning and latch engagement.
• Non-handed configuration: Compatible with correctly prepared left- and right-hand door applications.
• Long service life: 1,000,000 factory-tested cycles and 500,000 UL-verified cycles, according to Camden.

Technical Specifications

Commercial Applications

Designed for properly engineered access-controlled commercial entryways, public buildings, hospitals, offices, service entrances, warehouses and institutional openings using compatible rim panic or exit devices with a 3/4-inch Pullman latch. May be operated by compatible access-control panels, card readers, intercom relays, keypads or release systems. The strike does not replace the exit device itself.

Installation & Ordering Notes

Check the exact rim exit device and 3/4-inch latch geometry before ordering. Confirm mounting space, door and frame alignment, preload expectations, supply voltage, current capacity, monitoring connections and desired fail-safe/fail-secure operation. Fire rating applies ONLY to the fail-secure configuration in an approved assembly; do not assume any fire approval for fail-safe or unapproved openings. A complete egress design must satisfy building, accessibility and life-safety codes. Optional spacer (CX-EPD1289-SPC) and double-door adapter box (CX-RIM-SB), power supply, exit device and access-control equipment are separate items unless ordered as a package.

Commercial Door Worx provides Camden electric rim strikes, exit devices, locking hardware and access-control components for professional installers and facility maintenance teams.

Rim Exit Device Strike Compatibility

The Camden CX-EPD1289L is a surface-mounted rim exit-device electric strike designed for compatible 3/4-inch Pullman latchbolts. It is not interchangeable with the electric strikes used for a standard cylindrical lock or mortise deadlatch.

Important Features

• Preload-resistant operation: Intended to release properly specified rim exit device latches in the presence of limited door pressure; consult the 15 lb preload rating and required alignment.
• Latch status: Built-in latch monitor helps an access-control panel verify the status of the latch at the strike.
• Commercial Grade 1 strength: Heavy-duty surface-mounted design for appropriately prepared commercial door frames.
• Low-voltage control: Supports the specified selectable 12/24V AC/DC application and compatible monitoring circuitry.

Pre-Installation Verification

1. Identify the existing rim panic/fire-exit device manufacturer and model and confirm a compatible 3/4-inch Pullman latchbolt.
2. Check that the opening and frame support surface mounting, proper strike height and adequate latch engagement.
3. Confirm any required spacer, frame adapter or special mounting bracket is separately ordered when necessary.
4. Review the door's fire rating. When used on an approved rated opening, maintain the manufacturer-prescribed fail-secure arrangement.
5. Test the latch monitor, door alignment, powered release and unrestricted mechanical egress after installation.

Supplied: Selected CX-EPD1289L rim electric strike. Compatible exit bar, power supply, reader, door closer and access-control electronics are not included by default.
