The Falcon 4208 is the OEM cylinder retaining bracket for the Falcon 24 and 25 Series exit devices, used specifically with the CD (Cylinder Dogging), EA (Exit Alarm), and KOR (Key Override Release) cylinder options. It is listed in the Falcon 19/24/25 and XX Series Service Manual as the CD/EA/KOR cylinder retainer bracket, and appears in the 24/25 Series Refill parts table covering all eight device configurations: 24 Rim, 24-V SVR, 24-C CVR, 25 Rim, 25-V SVR, 25-C CVR, 25-C-WDC, and (F)25-M Mortise - in both panic and fire-rated variants.

The bracket's job is to hold the cylinder securely in its housing so it stays mechanically stable during key operation. Without correct cylinder retention, the cylinder can rock or shift in the housing during the turn sequence, which degrades the mechanical connection between the key turn and the dogging/alarm/release mechanism it's meant to operate.

What CD, EA, and KOR Are and Why the Same Bracket Covers All Three

All three options require a cylinder mounted in the exit device or its outside trim assembly. The bracket is the hardware that retains that cylinder, regardless of which option it serves.

CD - Cylinder Dogging: The most common application for this bracket. Cylinder dogging lets authorized personnel use the outside trim cylinder key to dog the pushpad in the depressed position - keeping the latch retracted so the door operates as a free-passage door without anyone having to press the pushpad each time. The key is inserted and given a 1/4 turn to engage or release the dog. On high-traffic doors during business hours, this eliminates thousands of unnecessary pushpad actuations per day and significantly extends the service life of the center case mechanism. The 4208 bracket keeps the dogging cylinder from working loose in its housing, which would eventually cause the dogging function to fail mid-turn.

EA - Exit Alarm: The EA option adds an exit alarm to the 24/25 Series device. A cylinder mounted in the device housing is used to arm and disarm the alarm - turn the key one direction to arm, the other to disarm. The 4208 bracket retains this alarm control cylinder in the correct position so the key operation consistently engages the alarm switching mechanism without the cylinder shifting.

KOR - Key Override Release: The KOR option provides authorized key entry from outside on what would otherwise be an exit-only door. A cylinder retracts the latch when the key is turned, allowing entry without operating the pushpad from outside. The bracket keeps the KOR cylinder aligned with the latch retraction mechanism so the key turn reliably produces latch retraction.

Falcon Exit Device Catalog: 24/25 Series CD, EA, KOR Cylinder Installation

The 4208 bracket is a shared component across all three options, which simplifies field parts stocking. A building with a mix of CD-dogged, EA-alarmed, and KOR-equipped 24/25 Series doors only needs one cylinder retaining bracket part number on the service van. The bracket itself is identical for all three applications - what changes is the cylinder and the mechanism it interfaces with, not the bracket.

The 4208 works across all 24/25 Series configurations because the cylinder housing geometry is consistent across rim, SVR, CVR, wide clearance, and mortise variants within the 24/25 Series family.
