assaabloy.com 139 Panic and emergency hardware Introduction Terminology Explanation Keeps Plates or components that the latch or bolt engages with to keep the door shut. Different door and frame styles require different keep solutions. Micro switch or Monitoring A device integrated into the hardware during manufacture that monitors the latch or bolt position (i.e. ‘door open’ or ‘door closed’) and can give a signal back to an alarm system. Dogging or lock back Ability to hold back bolts to prevent re-engagement with keeps to make the door a 'push/pull' passage door during the day. Rebated double door – active leaf Rebated double door leaves have a stepped and overlapping edge so it’s important to know which leaf has outer lip and therefore must open first, this is the active (or primary) leaf and typically has a latch product on it to secure against the inactive leaf. Rebated double door – inactive leaf Rebated double door leaves have a stepped and overlapping edge so it’s important to know which leaf has inner lip and therefore must open second, this is the inactive (or secondary) leaf and typically has a shoot bolt or Pullman product on it to secure it to the threshold and frame. Plain meeting stiles double door Plain meeting stile leaves have a square edge (and a clear gap between them) so each leaf can open independently of the other. They typically have shoot bolt or Pullman products on them to secure each leaf to the threshold and frame. Considerations for selecting the right exit hardware Useful terminology Hardware options Emergency hardware Device: Push pad, lever handle or paddle handle Certification: EN 179 Emergency hardware is an escape device operated by a small pad, paddle or handle. When the device is operated, the mechanism releases the latches or bolts holding the door shut. Due to the small contact point that will release the door, emergency exit devices are intended for use in restricted areas where all users are familiar with the building layout and know how to use the hardware. Key features: • Intended for use where emergency evacuation will be calm and controlled as all users are familiar with the hardware and building layout • Can be fitted to inward opening doors, depending on variant selected • Designed to provide safe and effective escape through a doorway • One single action to release the device See more details of EN 179 within the legislation section. Panic hardware Device: Push bar or touch bar Certification: EN 1125 Panic hardware is an escape device that features an activation bar that covers at least 60% of a door face. When the bar is pushed, the mechanism retracts the latches or bolts holding the door shut and the door swings open to enable escape. Operated by pushing the activation bar, panic units can only be fitted on the internal face of outward opening doors. Panic exit devices are a legal requirement for use in public access areas as they are very easy to use without any prior knowledge. Key features: • Intended for use in facilities with a large number of people and where panic situations may arise as all users may not be familiar with the hardware and building layout • Provides safe and effective escape through a doorway with minimum effort • One single action to release the device If there is any uncertainty about final application and/or users – specify a panic hardware solution. See more details of EN 1125 within the legislation section. Are there less than 60 occupants using the building? YES NO YES NO Are the building occupants aware of the fire action plan? Do I need an escape or panic hardware solution? If in doubt use EN 1125
