What else does the UL 325 Standard do? It also:
A door or grille is also required to only function by constant pressure to close operation if it is equipped without a monitored or properly functioning primary entrapment protection device. This means that in order for the door to close, a person must manually push and hold the close button until the door is closed. The control station must be mounted within sight of the door.
UL 325 requires the operator of rolling products to have particular forms of sensing devices and safety mechanisms: primary and secondary entrapment devices. Primary entrapment devices, such as ELR electric sensing edges, wireless sensing edge, and photo eyes, are used when you would like to close your door or grille with the single push of a button. Secondary entrapment devices can be used in conjunction with a set of primary entrapment photo eyes or with constant pressure to close operation. These devices include electric sensing edges with wireless edge kits, sensing/smoke seal edges, or a pair of non-monitored photo eyes.Please reference the chart below for information of each entrapment device:
