Briton Cam Action 2300 Series incorporates the same high efficiency cam action as the Briton 2700 Series, providing the same exceptional ease of use by reducing the resistance encountered when initialising the opening of the door. The Briton 2300 Series is offered as a simplified version of the Briton 2700 and is available with either a slide in trimplate or with a curved ‘Softline’ all-over cover which will suite with other Briton overhead door controls.

Briton Cam Action Closers - Why are opening and closing forces important?

For disabled people to have independent access through single or double swing doors, the opening force, when measured at the leading edge of the door must not exceed 30N between 0º and 30º from closed and 22.5N thence until 60º. These figures (post March 2005) are deemed to be manageable. Where fire (compartmentation) doors are concerned the closing force exerted becomes the overriding factor. BS EN 1154:1997 states that the closing moment for a power size 3 door closer must be a minimum of 18Nm at a point between 0º and 4º - In other words, achievable at any one point only and not throughout the angle. BS EN 1154:1997 Annexe A states that controlled door closing devices with a power size of less than 3 (see Table 1 of that standard for a full definition) are not considered suitable for use on fire door assemblies since they will be unlikely to provide the necessary torque.
