Overhead door closers with hold-back and free-swing functionality for busy corridors to ease flow of traffic.These door closers will close the fire door only when the fire alarm sounds. Hard wired to the alarm system (24 V) or in the case of the Freedor, completely wireless and battery operated.
Door closers can be mounted in different ways depending upon the application for which they are being used. The three most common mounting types are detailed below.
Fig 1 Mounting |
|
---|---|
Also known as regular or projecting arm, this is the standard fixing position for a universal door closer. This is where the door closer is fitted to the opening face of the door on the hinge side. When a door closer is fitted in a "figure 1" configuration the arms of the closer will project outwards from the door at around 90°. Please Note: Fig 1 is suitable for all fire doors. |

Fig 61 Mounting |
|
The second fixing position for a universal door closer is commonly referred to as "figure 61" or transom. This is where the door closer is inverted and the body of it fitted to the head of the door frame opposite the hinge side of the door. This application allows a door closer to be fitted on external doors without the closer having to be exposed to the elements. When a door closer is fitted in a "figure 61" configuration the arms of the closer will project outwards from the door at around 90°. Please Note: The Certifire certificate must explicitly state approval for a door closer to be compliant in this configuration. |

Fig 66 Mounting |
|
The third fixing position for a universal door closer is commonly referred to as "figure 66" or parallel arm. This is where the door closer is fitted to the closing face of the door opposite the hinge side of the door. The arm of the closer is then fitted to a bracket supplied with the door closer. This application allows a door closer to be fitted on external doors without the closer having to be exposed to the elements. When a door closer is fitted in a "figure 66" configuration the arms of the closer will run parallel to the door and frame. Please Note: The Certifire certificate must explicitly state approval for a door closer to be compliant in this configuration. |
