2.1 Actuating Bar The activating mechanism of an exit device is located on the egress side of a door and extends at least half the width of the door. The active surface of the actuating bar shall be visually and physically distinct from the rest of the device. Refer to local codes for location and length. Also called crOss bar or push pad.
2.2 Actuating Member The activating mechanism including an arm, push plate or paddle assembly of an exit lock on the egress side of the door. The active surface of the actuating member shall be visually and physically distinct from the rest of the device.
2.3 Door Prop Alarm Alarm sounds when the door is left open longer than a defined time period. If the door prop time expires and the door is open the alarm sounds. The alarm may reset when a) the door closes or b) some other manual reset.
2.4 Elctrical Fast Transient (EFT) "Transient" is a term applied to either parameter (Current or voltage). It describes either parameter (current or voltage) as a function of time during the period of adjustment (the transient period) when in a steady-state-circuit a switch is activated which changes the circuit and the parameters are adjusting to their new steady-state values. "Fast" is an arbitrary term,which describes the time between switch activation and the parameter becoming asymptotic to its new value. For the purposes of this Standard, a transient period of a millisecond or less is regarded as a "fast transient" or EFT.
4.2 Test Door When doors are referenced, the tests shall be performed on 3 ft by 7 ft x 1 3/4 in.(915 X 2134 x 45 mm) minimum doors of wood or metal with metal frames. The doors and frames shall be rigid enough to hold firmly and to withstand the tests outlined. Doors shall be hung on hinges or pivots. Provision shall be made for mounting appropriate measuring devices. A combined calibration and reading accuracy within 5% shall be required for values indicated for all applicable tests. Reinforcement is permitted to be used to prevent deformation of the door when the tests are being applied.
4.3 Slam Cycle Test Door Use a door meeting the description of 4.2. Use a door weighing 100 lbs.(45 kg) with the center of gravity located 18 in. (455 mm) from the hinge edge. Install the door in a steel frame with a 5/8 in. (15.9 mm) stop and mounted in a reinforced structure sufficient to withstand the test parameters. The door shall be installed to ensure door stop contact for the full height of the door. The stop contact surface shall not have any rubber bumpers or other cushioning means such as gasketing. Force required to overcome friction or out of balance condition shall be 1/4 lbf. (1.1 N) or less throughout the test measured perpendicular to the face of the door at a point 30 in. (762 mm) from pivot center. BHMA A156-29 pdf download.
