Heavy Duty Electric Latch Retraction Concealed Vertical Rod Device - (suits doors <915mm x <2533mm) Anodized Aluminium
The Quiet One®
A fluid dampener decelerates the touch bar on its return stroke and eliminates most noise associated with exit device operations. Furnished on all 99 Series Exit Devices
In accordance with BS EN 1125: 2008 Annexe A (informative) the device should be installed with the touch bar normally at a height between 900mm and 1100mm from the finished floor level when the door is in the secure position. Where it is known that the majority of the occupants of the premises will be young children, it is acceptable to reduce the fixing height accordingly.

- EL Electric Latch Retraction
The EL feature allows for the remote unlatching of exit devices. A control station operator can flip a switch to retract the latch bolt and immediately change an exit door to push-pull operation. A powerful, continuous duty solenoid retracts the latch bolt, either for momentary unlatching, or for extended periods of time. The EL feature is an alternative to manual dogging.
If manual hex-key dogging is required, specify HD-EL. If cylinder dogging is required, the standard cylinder dogging is not available, but special centre case dogging is available, specify SD-EL.
EL devices are also useful with automatic door operators and may be applied to fire-rated applications when under the control of an automatic fire alarm system.
The EL option does not include the power transfer from door to frame, the power supply, or the control operator. Refer to EPT-2 power transfer and the PS0.ELBB - 24Vdc Power Supply/Fire Relay (PSU) w. Battery Back-Up.
