Usage
The Bras poussant 225mm is designed for use with Dorma ED swing door operators, enabling secure and efficient automation of hinged doors where the lintel depth ranges from 0 to 225 mm. It is ideal for commercial and public buildings requiring reliable door movement control.
Advantages
- Allows installation on doors with varying lintel depths up to 225 mm, offering flexibility in different architectural settings.
- Supports automated opening angles up to a maximum of 110°, facilitating wide, accessible entryways.[2][3]
- Ensures smooth operation with adjustable final latching action and opening/closing speeds via potentiometer controls.[2]
- Compatible with safety features such as electric or motorized locks, lock feedback signaling, and integrated status LEDs for easy monitoring.[2]
- Mainly suitable for internal or external single- or double-leaf swing doors; may require additional hardware adjustments for specific fire protection requirements.[1][5]
Specifications
- Design / Materials: Push arm in silver finish (argent), robust construction; dedicated for use with the Dorma ED range (ED100/ED250) swing door operators.
- Sustainability & Standards: Closing force adjustable according to EN1154 (EN size class: EN 2–4), applicable on fire/smoke protection doors when equipped accordingly.[1][5]
- Main Dimensions & Performance: Lintel depth coverage: 0–225 mm; max. opening angle: 110°; operator weight: 12 kg; supported leaf weight up to 100 kg at this configuration; compatible door width: 700–1,100 mm;
Operating temperature range: –15 °C to +50 °C;
Relative air humidity max.: 93% non-condensing.
- Differentiating Features: Final latch adjustable between 7°–0°, hold-open time programmable from 30 s (up to 180 s optional), wind load compensation up to 150 N,
state indicator LED (power/fault/maintenance), selectable operating modes including automatic/permanent open/push-and-go functions from just 4° manual activation,
integrated function selector switch.
How it works
The push arm transmits motion from the Dorma ED operator directly onto the hinged door leaf. It manages automated movements—opening or closing—across variable lintel depths while supporting programmable speed profiles, hold-open times, and secure locking integration based on user needs and building safety requirements.[1][3][5]
