NOTICE
i i
Refer to the instructions for use of the used X-am 5x00
for a description of the display.
The visual and acoustic life signal (green LED ring and single
tone) is issued depending on the configuration
(1 - 60 seconds; default setting every 2 seconds). The life
signal can be configured using the Dräger CC-Vision PC
software (see Chapter 11 on Page 60).
In the event of an alarm, the visual and the audible alarm will
be activated (see Chapter 7 on Page 55).
The X-zone device amplifies the visual and audible alarm and
permanently transmits the alarm information via a wireless
connection or communication cable to further X-zone devices.

X-am 5x00 is critical for the correct response of the
X-zone device.
In the case of an alarm in a group, the display of local
alarms are prioritised on all devices over third party
alarms.
The X-zone is equipped with two different alarm generators:
Visual signal: LED ring (360°);

colours: red, green; pulsing.
Acoustic signal: Intense horn (108 dB (A) at 1 m distance/

120 dB (A) at 30 cm distance).
Triggering device:
As soon as a device detects an increased gas concentration,
this device will become the triggering device.
The triggering device forwards the alarms to all connected
devices wirelessly and/or via communication cable.
Receiving device:
All devices that receive an alarm from the triggering device
become receiving devices. The receiving devices generate a
secondary alarm. If the receiving device does not receive any
information from the triggering device, the secondary alarm on
the receiving devices is cancelled after 10 seconds.
NOTICE

The alarm-triggering device and the receiving devices
give a different visual alarm.
