Falcon 8240-77 – Frequently Asked Questions

1) Is the Falcon 8240-77 an arm for a manual door closer or for a powered operator?
It belongs to a powered unit. The 8240-77 is the main arm for the 8240 Series automatic door operator, not an arm for a manual surface closer. Manual closers take closer arms such as the Sargent 25-H hold open arm for 351 and 281 closers or the LCN 4000T-3077T standard arm, and those are not interchangeable with an automatic operator arm.
2) My building has Sargent and LCN closers on the other doors. Will the Falcon 8240-77 arm work on any of them?
No. Closer and operator arms are brand and series specific. The 8240-77 fits Falcon 8240 Series operators only. For a Sargent 351 or 281 closer you would order a Sargent arm such as the 25-CPS parallel arm with compression stop; for an LCN 1260 closer, the 1260-3077 regular arm with parallel arm bracket. Matching the arm to the body on each opening is the rule.
3) What is the difference between the Falcon 8240-77 main arm and a Sargent 25-H arm?
They serve different kinds of door hardware. The Falcon 8240-77 is a main arm for 8240 Series automatic door operators, sold as a replacement part for a powered operator system. The Sargent 25-H is a hold-open door closer arm for 351 and 281 closers in standard and top jamb mount, which is manual surface closer hardware rather than an operator component. If the unit on the door is a power operator, the closer arm is not a substitute for the operator main arm.
4) Can I order just the arm for a Falcon 8240 operator instead of replacing the whole unit?
Yes. The 8240-77 is sold on its own as the main arm, so a bent or worn arm on an 8240 operator is a parts swap rather than a full operator replacement. One option is offered, the main arm itself, so there is nothing else to specify when ordering.
5) The door needs a stop to protect the wall. Can I get that in a Falcon 8240-77?
The 8240-77 is the main arm for 8240 Series automatic operators and is built to the OEM specification for that system, so the arm itself is what the operator calls for. Where an integral stop is the requirement on surface closer hardware, Sargent lists the 25-CPS, a heavy duty parallel arm door closer with compression stop compatible with 351 and 281 closers, and the 25-CPSH, which combines the compression stop with hold-open. Sargent also offers the 1431-CPS TB EN, a heavy duty surface door closer with parallel arm and compression stop supplied as a complete Grade 1 closer rather than an arm alone.
6) Is there a Falcon 8240-77 equivalent from LCN?
LCN arm components are series-matched the same way the Falcon part is. The 8240-77 is engineered exclusively for 8240 Series automatic operators. On the LCN side, the 4000T-3077T is a standard arm replacement component for the 4000T Series and the 1260-3077 is a regular arm with parallel arm bracket for the 1260 Series. Each is tied to its own series, so an LCN arm is selected by matching the closer or operator body already on the door rather than by cross-referencing the Falcon number.
7) We are replacing an arm on a commercial entrance. Should we buy the arm or a whole new closer?
Both routes exist in the Falcon and Sargent lines. The Falcon 8240-77 is a replacement part supplied as an arm only, for commercial use, and integrates with an existing 8240 Series operator without modification. Sargent covers the arm-only route with the 25-CPS and 25-H, both heavy duty Grade 1, and the complete-unit route with the 1431-CPS TB EN, a heavy duty Grade 1 surface door closer supplied with its parallel arm and compression stop. The arm-only path keeps the existing body on the door; the complete closer replaces the body as well.
8) Is the Falcon 8240-77 arm rated for commercial traffic, or is it a light residential part?
Commercial. The 8240-77 main arm is a commercial-duty door control component, built for the entrances it gets specified on: office buildings, healthcare, retail entries, schools, government buildings and multi-tenant residential.
9) Who should install a replacement main arm on an automatic door operator?
A qualified door technician. The 8240-77 goes on with standard tools, but an automatic operator arm has to be reconnected and the operator rechecked against the manufacturer's instructions for the 8240 before the door goes back in service. Falcon publishes the procedure in its door controls catalog and the operator's own installation instructions.
10) Is the Falcon 8240-77 handed?
The 8240-77 is a series-specific main arm engineered exclusively for 8240 Series automatic operators, so the fit is determined by the operator it mounts to. Among comparable arms, the LCN 1250-3049/PA hold open arm assembly is described as a non-handed design, which is the arm to look at when a single part number needs to cover both hands of a pair of surface-closed doors.
11) What is the difference between a regular arm and a parallel arm when replacing door closer arm hardware?
The mounting geometry differs and the part numbers follow it. The LCN 1260-3077 is a regular arm supplied with a parallel arm bracket, and the LCN 4000T-3077T is a standard arm replacement component for the 4000T Series. Sargent's 25-CPS is a parallel arm with compression stop, while the 25-H is a hold-open arm for standard and top jamb mount. The Falcon 8240-77 sits outside that choice: it is the main arm for 8240 Series automatic operators, where the arm is dictated by the operator rather than selected by mounting style.
