Connection of the relay output
During operation
During operation the values for each gas detected are
displayed on the inserted Dräger X-am 5000.
The visual and acoustic life signal (LED ring green 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 (refer to “Configuring the device” on
page 39).
In the event of an alarm, the visual and the audible
alarm will be activated (refer to “Alarms (default
settings)” on page 36).
The Dräger X-zone 5000 will amplify the visual and
audible alarm and will permanently transmit the alarm
information, via a wireless connection or via cable,
to further Dräger X-zone 5000 devices.
Alarms (default settings)
The Dräger X-zone 5000 is equipped with two different
alarm generators:
– Visual signal: LED ring (360°);
Colours red, green; pulsing.
– Acoustic signal: Intense horn (108 dB (A) in 1 m
distance/120 dB (A) in 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.
Concentration pre-alarm A1
The alarm is indicated by an
intermittent alarm message:
Display » A1 « and measured value alternating: not
for O2!
– The pre-alarm A1 is not self-latching and stops when
the concentration has dropped below alarm
threshold A1.
The triggering device at A1:
– A single tone sounds and the LED ring flashes red
(main alarm).
The receiving device at A1:
– A single tone sounds and the LED ring flashes red/
green (secondary alarm).
Acknowledging the pre-alarm:
z
Press key on the Dräger X-am 5000 of the
triggering Dräger X-zone 5000.
– Only the audible alarm will be switched off.

NOTICE
The displays on the Dräger X-am 5000 are described
in the Instructions for Use for the gas detection
instrument being used.
NOTICE
The alarm settings (e. g. self-latching/
acknowledgeable) can be configured using the
Dräger CC-Vision PC software. The configuration
of the Dräger X-am 5000 is critical for the correct
response of the Dräger X-zone 5000.
NOTICE
The alarm-triggering device and the receiving devices
give a different visual alarm.
