force applied to the operating element, which is necessary to withdraw or release all the bolt head(s) from the keeper(s), such that a door can be opened

vertical rod
extension of the bolt head of an emergency exit device that links it to the operating element via the operating mechanism
panic exit device
exit device conforming to EN 1125 intended to give safe and effective escape through a doorway with minimum effort arid without prior knowledge of the panic exit device allowing safe escape even in the event of the door being under pressure such as by people being pushed against the door in the direction of escape
NOTE 1 A panic exit device contains bolt head(s) that engage(s) with a keeper(s) In the surrounding door frame and/or floor for securing a door when dosed. The bolt head(s) can be released by the bar positioned horizontally across the Inside face of the door when it is moved anhere along its effective length in the direction of travel and/or in an arc downwards.
NOTE 2 Panic exit devices are Intended for use where panic situations can arise. In a panic situation, a group of people will react differently from an individual. When two or more people are rushing to an escape door, probably in darkness and/or smoke, It is possible that the first one to reach the door will not necessanly operate the panic exit device, but can push the surface of the door (door under pressure) while other people will be Lrying to operate the horizontal bar by hand or body pressure.
NOTE 3 When a door opens in the direction of exit, a panic exit device can be used instead of an emergency exit device subject to local regulations.
3.19
emergency exit device
exit device conforming to EN 179 intended for emergency purposes where panic situations are not likely to arise, to give safe and effective escape through a doorway with one single operation to release the emergency exit device, although this can require prior knowledge of its operation (see Figure 1 and Figure 2)
NOTE 1 An emergency exit device contains bolt head(s) that engage(s) with a keeper(s) in the surrounding door frame and/or floor for secuflng a door when closed. The bolt head(s) can be released by the lever handle or the push pad positioned on the inside face of the door.
NOTE 2 Exit devices conforming to EN 179 are intended for emergency purposes where panic situations are not likely to arise. Where a pressure against the door caused by people in a panic is foreseen, then a panic exit device conforming to EN 1125 should be used.
NOTE 3 Emergency exit devices are suitable also for Inwardly opening single leaf exit doors, where local building regulations allow.
NOTE The term pull pad is sometimes used instead of push pads for use on Inwardly opening single leaf exit doors.
Compliance shall be verified by visual inspection and functional tests
4.1.6 Double doorset
The design of an emergency exit device intended for use on double doorset leaves shall allow both leaves to be opened simultaneously and to swing freely in the direction of exit once the door has been released.
NOTE 1 The construction and installation ol a specific doorset assembly, including choice of hinges, leaf thickness and leaf width, can have a significant effect on the ability of both leaves to open simultaneously. These issues are beyond the scope of this European Standard. Additional guidance is given in A.5
NOTE 2 For example, on rebated double doors, operating the emergency exit device on the inactive leaf will release both the inactive and the active leaf.
Compliance shall be verified by visual inspection and functional tests carried before and also after durability test.
4.1.7 Corrosion resistance
The corrosion resistance shall comply with 4.2.9 or be at least grade 3 in accordance with
EN 1670:2007, 5.6.
4.1.8 Exposed edges and corners
An emergency exit device shall have all edges and exposed corners, that are likely to cause injury to
persons using the exit, rounded to a radius of not less than 0,5 mm.
Compliance shall be verified by visual inspection and measurements.
4.1.9 Temperature range
Materials selected in the design of an emergency exit device shall be suitable for the operation of the emergency exit device between temperatures of —10 C and +60 C. This requirement shall be verified by the test specified in 6.2.2. The maximum operating force at —10 °C and at ÷60 C shall not exceed 50 % in excess of the operating forces measured at 20 °C.
4.1.10 Suitability of emergency exit devices for use on smokelfire-resisting doorsets
Emergency exit devices that are suitable for use on smoke/fire-resisting doorsets shall conform to the requirements of 4.2.3, 4.2.4, Annex B and be classified according to 7.4.EN 179-2008 pdf download.
