Macwood underfloor low energy ‘slow-open’ automatic/ manual door operators are ideal for use by everyone, especially people with disabilities without compromising building aesthetics, as the operator is concealed. This is similar to the standard UFSO operator except the heavy duty unit gives greater control of the door through independent closing and latching speed adjustment and a fully adjustable hydraulic back check.

By definition a low energy door operator, when opening a door, will not exceed 1.6 joules of kinetic energy which is the safe maximum specified by BS 7036 part 4. The safety sensor mounted on the push side will automatically re-open a closing door. Doors fitted with a Macwood ‘UFSO H28’ operator can always be opened manually. They function as a normal hydraulic damped door closer which, in the event of a power failure is an essential feature. Single action automatic /manual operation. Single action assisted opening. ‘Fly-Open’ for smoke ventilation, air pressure relief and escape (open on fire alarm). Incorporation of PSB locking bolts integrated with the access control (where door widths allow). Break-out where door construction permits.		Switch options include a range of push buttons, touch sensitive handles (for power assistance) remote controls and most access control switches including fobs, card readers, key pads and biometric readers. Suitable for centre pivoted doors. Off Set Pivoted doors. Hinged doors (for use with an off set strap). Standard - Ribbed aluminium. 25mm tray to take floor finish.
