ePED With ePED (electrically controlled Panic Exit Device), the electrically controlled emergency exit technology can be integrated into the door system. The system is connected via Hi-O bus technology. Safety functions such as electrical locks can be easily integrated. With the ePED technology, ASSA ABLOY technically paves the way for the new possibilities of EN 13637. The most important advantage of ePED is the simple coupling of two previously independent systems: the safety function of locking an emergency exit and the control of the door technology. With ePED, the door is safely released both when the emergency switch is actuated and in the event of a fault. Another innovation is the option of time-delayed escape door release. It is particularly suitable for facilities such as nursery schools or dementia stations in hospitals and nursing homes. The connection of ePED to the Hi-O-Bus technology makes wiring much easier.
