60 Dräger X-zone 5500
During operation
7 During operation
During operation, the measured values for every measured
gas are displayed by the inserted X-am 5x00.
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 on page 65).
In the event of an alarm, the visual and the audible alarm will
be activated (see chapter 8 on page 60).
The X-zone 5500 will amplify the visual and audible alarm and
will permanently transmit the alarm information, via a wireless
connection or via cable, to further X-zone 5500 devices.
8 Alarms (default settings)
The X-zone 5500 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.

CC-Vision PC software. The configuration of the X-am
5x00 critical for the correct response of the X-zone
5500.

alarms are prioritised on all devices over third party
alarms.
