1 Safety Regulations
1.1 Correct Use
The S5000 Gas Monitor, hereafter also called device, is a gas monitor for measuring toxic and
combustible gases as well as oxygen. Using sensors, the device tests the ambient air and triggers
the alarm as soon as the gas exceeds a specific concentration level.
WARNING!
Read this manual carefully. The device will perform as designed only if it is used, installed and
maintained in accordance with the manufacturer's instructions. Otherwise, it could fail to perform
as designed and persons who rely on this device for their safety could sustain serious personal
injury or loss of life.
WARNING!
Do not use silicone-type lubricants in assembling the device and do not allow silicone vapors to
be drawn into the flow system while in operation. Silicone can desensitize the combustible gas

larger and more user friendly setting. The Bluetooth® communication can interact with the device
within a maximum transmission distance of 70 feet (21 m).
WARNING!
Bluetooth®Operation is dependent upon signal availability of the wireless service(s) necessary to
maintain the communication link. Loss of wireless signal will prevent communication of alarms and
other information to linked devices. Take appropriate precautions in the event a loss of wireless
signal occurs.
Failure to follow the above warning can result in serious personal injury or loss of life.
The S5000 and user provided communication device will need to be paired. This requires both
devices to be in range and for a pairing sequence inputting a 6 digit pairing code. The instructions
will be displayed on both the S5000 and communication device.
The user menu can also be accessed using the round GM magnet on the General Moni-
tors logo.
If ordered with Bluetooth®, the device will be shipped with Bluetooth®enabled. See
section 4 for instructions on disabling Bluetooth®.
If the device was not ordered with Bluetooth®it cannot be upgraded.
There are communication devices capable of being used in classified areas. Please
contact your MSA representative for additional information.

General Monitors S5000
2.4 Dual Sensing
The S5000 supports two Digital Sensors, or one IR400 point IR detector and one Digital Sensor
simultaneously with four wire connections. However, the device will only support one passive
sensor, either combustible catalytic bead or metal oxide semiconductor (MOS) sensors, based on
the ATO configuration. Passive catalytic bead uses three wires, passive MOS uses four wires.
The S5000 Gas Monitor generates two independent analog outputs; one for each sensor
connected to the transmitter. The analog output associated with Sensor 1 also has the digital
HART (Highway Addressable Remote Transducer) communication superimposed on the analog
signal. If two sensors are connected, the digital HART communication carries information for both
sensors.
2.5 Retrofit Installations
The S5000 has the conduit entries located in the exact same orientation and distance from the
wall and the mounting holes for attaching to a wall are identical to the S4000 Series detectors.
Users will be able to re-use the existing wiring for the remotely mounted sensors.
2.6 XCell Sensors Optimized for Fixed Gas Applications
XCell toxic and combustible catalytic bead sensors are developed and manufactured by MSA.
Now optimized for fixed gas applications, the XCell sensor platform is available in the S5000 and
provides multiple benefits, including a standard 3-year warranty on all XCell sensors.
One important optimization for fixed gas was incorporating the GM catalytic bead into the XCell
sensor.
The XCell Oxygen sensor does not use lead, but rather a non-consuming reaction chemistry. The
XCell Oxygen sensor is expected to last well over 3 years and can be safely stored on the shelf
for at least 1 year without sensor performance degradation.
2.7 TruCal Sensing Technology for CO and H2S Electrochemical Sensors
Using patented pulse check technology and proprietary Adaptive Environmental Compensation
(AEC) algorithms, XCell sensors wtih TruCal verify operation.
Automated pulse checks are the muscle behind the TruCal technology. Every six hours, an elec-
trical pulse stimulates the XCell sensor similar to having actual calibration gas applied, providing
a snapshot of the sensor's sensitivity at the time of the pulse. Using this sensitivity snapshot, the
sensor can diagnose sensor failures like electrode poisoning, electrolyte leaking, or electrical
connectivity issues. The sensitivity snapshots are mapped over time to provide an overall Life &
Health status as either "Good" or "Fair" if the sensor is approaching end of life.
But that's not all. The brains of the TruCal technology lie within the proprietary Adaptive Environ-
mental Compensation (AEC) algorithms. AEC uses the sensitivity snapshots provided by the
pulse check to adjust sensor output, compensating for environmental impacts on sensor accu-
racy. If the AEC adjustment is greater than expected based on typical environmental impact vari-
ations, the transmitter LED’s will slowly flash GREEN, indicating that the sensor should be
calibrated to reset the AEC cycle. The result is a sensor that actively self-monitors for operation
and accuracy, with far fewer manual calibrations.
Actual TruCal sensor performance will depend on the application, background gas exposure, and
environment. To validate XCell sensors with TruCal, it is recommended that users follow their
regular calibration cycle and record the "as found" and "as left" values. This data can be used to
extend the time between calibrations depending on the required specification of the application.

2.8 SafeSwap
The S5000 comes with patented SafeSwap technology, which allows users to change or replace
XCell sensors without needing to power down the instrument. Swap delay is enabled on the
S5000 by default; a feature that gives users a 2 minute window to change sensors without trig-
gering a fault condition. SafeSwap and Swap Delay are only applicable for XCell sensors. For
more information on SafeSwap and Swap Delay, see section 6.
WARNING!
As part of the product certification, it was verified that optional communication functions of this
gas detection instrument while operating at the maximum transaction rate do not adversely
affect the gas detection operation and functions of the instrument. The product certification,
however, does not include or imply approval of the SafeSwap feature, communications
protocol or functions provided by the software of this instrument or of the communications
apparatus and software connected to this instrument.
Follow the warnings below when removing or replacing sensors. Reference Fig. 3 for compo-
nent overview.
- Never remove or replace a Sensor Body Assembly or an IR400 while under power or when
explosive hazards are present.
- Confirm that the area is free of explosive hazards before removing or replacing an XCell
Sensor under power.
- To remove an XCell Sensor, unscrew XCell Sensor three full turns, wait 10 seconds, and then
remove the XCell Sensor completely.
Failure to follow the above warnings can result in serious personal injury or loss of life.
