HW-group Damocles2 1208

Undetected water leaks or water ingress can lead to severe damage in server rooms, data centers, or industrial facilities. The Damocles2 1208 from HW-group provides a professional IoT-based solution for remote monitoring and control of digital inputs and outputs. With 12 digital inputs (DI) and 8 digital open-collector outputs (DO), the device is perfectly suited for connecting water detectors and leak sensors while automatically triggering countermeasures.

Thanks to integration with the SensDesk portal and support for modern protocols such as HTTPS, IPv6, MQTT, and SNMPv3, alarms can be easily integrated into existing IT and SCADA environments. Real-time alerts maximize responsiveness to water leaks.

Technical Features of Damocles2 1208

• 12 digital inputs (DI): for dry contacts such as water leak detectors, door sensors, smoke detectors
• 32-bit S0 pulse counters: store consumption data and sensor events even during power outages
• 8 digital open-collector outputs (DO): for controlling external relays or systems (max. 50 V / 100 mA)
• Virtual outputs (VDO): up to 8, box-to-box link with Damocles2/Poseidon2 devices in the LAN
• Data logger: stores more than 250,000 events with analysis via HWg-PDMS and Excel export
• Protocols: SNMP (v1/v3), MQTT, HTTPS, Modbus/TCP, XML
• Alerting: e-mail, SNMP trap, SMS, or voice call (via HWg-SMS-GW3 or HWg-Trigger)
• Power supply: 9–30 V DC, optional PoE (Set version)
• Operating temperature: –30 °C to +85 °C

Water Leakage Protection & Alerts

With the Damocles2 1208, a reliable early warning system against water ingress can be implemented. Up to 12 water detectors and WLD sensors can be connected via the digital inputs. When liquid is detected, the device immediately sends alerts by e-mail, SNMP trap, or SMS. Additionally, through the 8 outputs, external systems such as pumps, sirens, or emergency shutdowns can be activated automatically.

Typical Applications

• Data centers & server rooms: protection from water leaks under raised floors or from HVAC units
• Telecom facilities: leak protection in sensitive technical rooms
• Industrial plants: integration of water and environmental detectors into SCADA systems
• Building technology: securing heating/cooling systems and basements
• Smart buildings: automation of water leakage alerts and control against flooding

Integration & Software

The Damocles2 1208 is fully compatible with HWg software solutions such as SensDesk, HWg-PDMS, and HWg-Trigger. Open interfaces allow for seamless integration into SCADA and IoT systems (Azure, AWS). The box-to-box feature with virtual outputs enables leak signals detected by one device to automatically trigger relays in other devices.

Alarm Control

Alarm escalation in real time can be achieved through multiple channels:

• E-mail directly or via the portal
• SNMP traps for centralized monitoring systems
• SMS/voice calls via SMS gateway
• Relay outputs for direct physical countermeasures

Versions

• Damocles2 1208: base version of the I/O device
• Damocles2 1208 Set: includes 12 V / 1 A power adapter, installation CD, and manual

Can the Damocles2 1208 detect water leaks?

Yes, up to 12 DI inputs can be connected to water detectors or WLD sensor cables, which immediately report leaks.

How are alarms triggered in case of water ingress?

Alerts can be sent via e-mail, SNMP trap, or SMS/voice notifications through a gateway, with up to 5 recipients supported.

What countermeasures can be controlled?

The 8 DO outputs allow automatic activation of pumps, ventilation systems, alarms, or emergency shutdowns.
