Alpais can integrate alarm status from a compatible external hydrogen gas
detector into the battery monitoring system for battery rooms, enclosures and
other stationary battery environments.
The hydrogen detector performs the gas sensing. Alpais receives the detector's
configured alarm output through the Control Module and presents the resulting
status within
Alpais Battery Monitoring Software
.
What This Integration Covers
- Integration of a compatible third-party hydrogen gas detector
- Alarm-status input to the Alpais Control Module
- Hydrogen alarm visibility in the Alpais monitoring interface
- Alarm event recording according to the configured system
- Email notification for registered users
- Project-specific sensor quantity, location and alarm-threshold engineering
Important System Boundary
Alpais does not replace the hydrogen detector, ventilation system, gas-safety
controller or site alarm system. The external detector is responsible for
measuring hydrogen concentration and generating the configured alarm output.
Alpais provides alarm collection, display, recording and notification within
the battery monitoring platform.
Why Hydrogen Monitoring May Be Required in Battery Rooms
Certain battery technologies can release hydrogen during charging, overcharging
or abnormal operating conditions. Whether gas detection is required depends on
the battery technology, charging system, room volume, ventilation, battery
quantity, operating conditions and the site's safety assessment.
A dedicated hydrogen detector can provide an alarm when the configured
concentration threshold is reached. Integrating that alarm with Alpais allows
battery-condition data and environmental alarm status to be reviewed through
the same monitoring interface.
Hydrogen Detector Connection to Alpais
A compatible hydrogen detector or gas-safety controller can provide a
relay or dry-contact output when its configured alarm condition is reached.
This status signal is connected to an available input on the Alpais Control
Module.
The selected detector, output type, power supply and interface wiring must
be confirmed during project engineering. Direct compatibility should not be
assumed without reviewing the detector datasheet and Control Module input
requirements.
Monitoring and Alarm Notification
When the external detector changes its alarm-contact state, the Alpais Control
Module processes the input and transfers the status to the software. A hydrogen
alarm can then be displayed in the interface, recorded in the event history and
included in email notifications sent to registered users.
Because this is a status-based integration, the Alpais interface normally shows
the detector's alarm condition rather than a continuously measured hydrogen
concentration value. Display of an actual concentration value would require a
separately confirmed detector output and communication architecture.
Sensor Quantity and Installation Location
The required number and location of hydrogen detectors cannot be defined as one
sensor per system or one sensor per battery room in every project. The design
should consider room dimensions, ceiling height, ventilation pattern, possible
gas-release points, detector coverage, battery layout and the applicable site
safety requirements.
Detector mounting height, enclosure protection, calibration requirements and
maintenance access must follow the selected detector manufacturer's instructions
and the project's gas-detection engineering.
Hazardous-Area and Enclosure Considerations
An IP rating such as IP65 describes enclosure protection against dust and water;
it does not by itself establish suitability for an explosive atmosphere.
Where the installation location is classified as hazardous, the detector,
enclosure, cable glands, wiring method and complete installation must be selected
for the applicable hazardous-area requirements.
Related project considerations are described on the
ATEX Battery Monitoring
page.
Integration with Battery and Room Monitoring
Hydrogen alarm status can be viewed together with battery voltage, internal
resistance, battery temperature, string measurements and other configured
environmental inputs.

Other battery-room options are available through the
Local Room Monitoring

Industrial Solutions

Information Required for Project Evaluation
Project evaluation should include the battery technology, battery quantity,
room dimensions, ventilation details, detector model, alarm threshold, output
type, power supply, enclosure rating, hazardous-area classification where
applicable and required notification workflow.
