HW-group Damocles2 MINI

Water leaks and unnoticed water ingress can cause major disruptions, from halting small facilities to creating severe damage in server rooms, data centers, or industrial environments. With its flexible design, the HW-group Damocles2 MINI offers a compact and reliable solution to monitor digital inputs for water detectors and forward alarms in real time. Integrated with the SensDesk portal or SCADA systems, the device is perfectly suited for remote monitoring and IoT-based infrastructure protection.

The Damocles2 MINI is equipped with 4 digital inputs (DI) for dry contacts – such as water leak sensors, door contacts, or smoke detectors. Each input includes a 32-bit S0 pulse counter that retains values even during power loss. With 2 relay outputs (DO, NO/NC), external systems like pumps, alarms, or backup power supplies can be controlled. This makes the device a versatile water protection solution.

Technical Features of Damocles2 MINI

• 4 digital inputs (DI): for dry contacts, e.g., water leak detectors
• 2 relay outputs (DO): NO/NC, for local or remote control
• S0 pulse counters: store consumption data even during power outages
• Virtual outputs (VDO): link up to 8 box-to-box relay outputs over LAN
• Data logger: stores over 250,000 events
• Connectivity: Ethernet (RJ45, 10/100 BASE-T), optional PoE (Set version)
• Secure protocols: HTTPS, IPv6, SNMPv3, MQTT, HWg-Push, XML
• Alerting: e-mail, SNMP trap, SMS, or voice via SMS gateway
• Power supply: 9–30 V DC or PoE (only MINI Set)

Protection Against Water Leakage and Ingress

In combination with water leak sensors, the Damocles2 MINI becomes an early warning system for fluid ingress. Typical applications include monitoring raised floors, HVAC condensation, sensitive technical rooms, or pipelines. In case of an alarm, an e-mail or push notification is sent immediately, supplemented by optional SMS or voice alerts via gateway. Relay outputs can automatically activate countermeasures such as pumps or sirens.

Typical Applications

• Data centers: early leak detection in raised floors or air conditioning systems
• Telecommunications: moisture protection for base stations and technical rooms
• Building technology: monitoring heating and cooling systems for water ingress
• Industrial facilities: monitoring machine rooms and production lines
• Smart buildings: integration into automation systems for water protection and energy monitoring

Integration & Software

Through SensDesk portals, alarms can be centrally evaluated, PDF reports created, and long-term graphs displayed. Combined with HWg-PDMS, S0 pulses can be converted into consumption values and exported to Excel. With open API support (SNMP, Modbus/TCP, MQTT, XML), integration with SCADA systems and IoT platforms such as MS Azure or AWS IoT is straightforward. Developers can use the HWg-SDK (C#, PHP, Java) for seamless integration.

Alerting & Control

When an input signal changes state (e.g., water leak detected), the Damocles2 MINI sends real-time alerts. Possible methods include:

• E-mail notifications directly from the device or via portal
• SNMP traps for centralized network monitoring
• SMS/voice alerts through HWg-SMS-GW3 gateway
• Relay control: activating pumps, sirens, or safety shutdowns

Versions

• Damocles2 MINI: base unit with 4 DI and 2 relay outputs, metal housing
• Damocles2 MINI Set: includes 24 V power adapter, software CD, and quick start guide

Can the Damocles2 MINI detect water leaks?

Yes, when connected to water leak sensors. Through its digital inputs (DI), it instantly detects a signal if liquid ingress occurs.

What alarm methods are available in case of water ingress?

Alarms can be sent via e-mail, SNMP trap, or, through external gateways, also via SMS or voice call.

Is the Damocles2 MINI suitable for SCADA integration?

Yes, with built-in support for SNMPv3, Modbus/TCP, and MQTT, it can be natively integrated into SCADA and IoT systems.
