Conflict of objectives emergency exit
Emergency exits enable persons in case of an emergency to leave a danger area on
the quickest way. Because these doors may not be closed, however, sometimes they
will be used for e.g., in big stores by unauthorized persons as a hatch for stolen
goods or something like that. The outcome of this is a continuous conflict of
objectives.
Conflict solution
The emergency exits can be efficiently protected against unauthorized use with our
electronic alarm system. For the authorized use the door can be activated with a key.
For further details, please refer to the assembly instructions of ZAS-2020.
The ZAS-2020 is a control and switching panel for the remote monitoring and the
remote control from up to 7 connected single door surveillances of the type
FWS-2020.
Control elements and equipment
The central control and switching panel takes over the remote monitoring of all
connected single door surveillances and other control tasks. The handling of the
central control and switching panel occurs by a key switch and 8 further remote
controlled keys. The key switch makes sure that only authorized persons can operate
the connected devices by remote control.
The status from up to 7 connected single door surveillances is indicated with
3 LED’s in green, yellow and red.
Special Functions
A special feature called “automatic activation on fire alarm” can be installed by an
expert if necessary.

Operation element key switch (profile cylinder lock)
Wear-free profile cylinder lock with the authorisation to operate the connected
devices by remote control.
The key can be turned around several times in the same direction without damaging
the device. The lock has a magnetic switch contact. Therefore, turning of the key you
feel only little resistance.
Unintentional destroying of the mechanical contact switch is excluded by the design
of the lock! Pull off the key by turning back in the suitable „0 “-position. With it you
avoid unintentional switching functions and false alarms.
Blocking the remote control over the central control panel
The key switch ensures that unauthorized persons could not activate the connected
devices.
Procedure: key rotation left, anticlockwise.
Indication: yellow LED „Z”= on

Identification of the single door surveillance
In all connected single door surveillances of the type FWS-2020 an identification
number has to be set. The central control panel assigns the connected devices
(according to the identification number) to the number on the display panel.
The Status - LEDs
Three indication lights (LED green, yellow and red) are assigned to every door
Yellow indication – LED
Unlocked door: LED = on, in case of surveillance: LED = off
Green indication – LED
Door contact closed: LED = on, door contact open: LED = off
Red indication - LED
Alarm activated: LED = on, Alarm off: LED = off

emergency exits will be automatically unlocked in case of fire and the flashlight will
be activated as a orientation guide. The green and red indication lamps „Z“ inform
you about the status of fire alarm.
