Description
Activation delay
With
Activation delay
, the key must be turned and held for longer than the ad-
justed delay time for unlocking, etc.
Release delay
The
Release delay
is the wait time until the escape door is unlocked after actua-
tion of the Emergency Open push-button.
Terminal
The
ePED
®
1386-00 door terminal
(
terminal
) comprises several modules (Fig. 4)
installed in a wall-mounted housing.
Terminating
A connecting conductor or a bus system must be
terminated
with a terminating
resistor.
Remote interface
If the connecting conductor is longer than 10 m, it is a
remote interface
(inter-
face with extended connection lead)
Ethernet
An
Ethernet
is a data network (LAN technology).
Gateway
A
gateway
(e.g. Ethernet gateway) connected devices to the network.
Topology
Bus topology (
topology
) refers to the structure for the interconnection of multi-
ple devices via bus. The
topology
is decisive for the safeguarding of the network
against failure, the performance, and the selection of suitable hardware.
Physical and logical
topologies
are differentiated between:
· the physical
topology
describes the layout of the network wiring,
· the logical
topology
describes the data flow between the end devices.
Hi-O Technology™
bus
The
Hi-O Technology™ bus
(Highly Intelligent Opening) is a bus for the connec-
tion of electronic components (devices) in door systems. It is used for the con-
trol of a door in each case. The status monitoring and exchange of information
between the individual devices takes place via CAN bus.
A central logic controller can be omitted, because each device has its own con-
trol unit. For escape route technology, it is a closed system with permanently as-
signed bus addresses.
All devices are interconnected via four-core cables. Conventional devices can be
connected via I/O boxes. Integration into a building network (Ethernet) or the
interaction of multiple doors takes place via a gateway (e.g. an Ethernet gate-
way).
Hi-O group
Assignment to a
Hi-O group
offers the possibility of organising components into
groups. The Hi-O group switches are basically set to position 0 (Off) for the
ePED
®
1386-00 door terminal
.
