1.3.0 Functions of GfS e-Bar® 70073x, 70074x
Local alarm types
GfS e-Bar® activated
When activated the display of the cabled GfS e-Bar® is permanently illu-
minated green. Green is signaling that the door is alarm secured but
might be opened at any time. In case of battery supply the GfS e-Bar®
works in an energy saving mode without background illumination. The
display shines for just about 15 sec. green and expires then.
Pre-alarm
While slightly pressing the GfS e-Bar® a red flashing light and an acoustic
alarm (95dBA/1m) is emitted, which expires as soon as the GfS e-Bar® is
released. The prealarm is activated just during the first mm of the pushing
movement. The correct moment when the pre-alarm is turning into a main
alarm can be adjusted by a regulating screw resp. in older versions of the
GfS e-Bar® by a reed contact (see operating manual page 8). It would be
ideal if the pre-alarm is set in a way that the main alarm is just activated
when the GfS e-Bar® is pushed to a point in which the door is released.
The pre-alarm can be transmitted to a central display
Main alarm in case of an unauthorized or an emergency passage
When pressing the GfS e-Bar® completely the door is released. At the
same time the display emits an intermittent green light and a permanent
alarm with 95dBA. The acoustic and visual alarm can be just switched off
on the integrated key switch. The main alarm can be transmitted to a cen-
tral display. With remote technology the main alarm is transmitted via
channel 1.
Battery Control
When the GfS e-Bar® is battery supplied a gentle acoustic alarm in an in-
terval of 60 sec is emitted as soon as the voltage drops below 7 V. The
display is not shining. The alarm is active till a new battery is connected.
Door-too-long-open-Alarm
Pre-condition for this feature is a reed-contact which is installed
on the door and connected to the GfS e-Bar®. When the single re-
lease has been activated on the integrated key switch and the
door stays open for more than 15 sec. a gentle “door-too-long-
open-alarm” is emitted in an interval of 3 sec. This alarm indicates
that an authorized person has left the door open. As soon as the
door is closed the alarm expires.
