THORN SECURITY
P/O: 607244
MINERVA ALARM RELAY
CONTACT RATING: 24VDC, 250VAC, 25A, 50HZ
CODE: 567.007.009
The Thorn Security Minerva Alarm Relay (part number 607244) is a dedicated switching relay module designed for use within the Minerva fire alarm and detection system. With a contact rating of 24VDC / 250VAC at 25A, 50Hz, this relay provides a robust and reliable means of transmitting alarm signals or triggering auxiliary outputs — such as ventilation shutdown, door release, or remote notification systems — when an alarm condition is detected. As a core component within a marine fire alarm system, it plays a direct role in ensuring that alarm events are correctly communicated and acted upon across the vessel, supporting both crew safety and regulatory compliance.
Key Features
✓ Switching relay module purpose-built for the Thorn Security Minerva fire alarm platform, enabling alarm signal routing and auxiliary output control.
✓ Rated contact capacity of 24VDC and 250VAC at 25A, 50Hz, providing flexibility for both DC and AC load switching in marine electrical environments.
✓ Designed for integration with Minerva fire alarm panels and associated control infrastructure; compatibility with specific panel versions or configurations should be confirmed prior to installation.
✓ Suitable for installation within fire alarm panel enclosures or designated equipment rooms; exact mounting requirements and environmental ratings should be verified against vessel drawings and system documentation.
✓ As a replacement or service part for an active fire detection system, correct installation and commissioning by a qualified technician is essential to maintain system integrity and SOLAS compliance.
Marine Applications
✓ Integration within Thorn Security Minerva fire detection and alarm systems aboard commercial vessels requiring certified fire alarm infrastructure.
✓ Auxiliary relay output control for ventilation shutdown, fire damper activation, or suppression system triggering upon alarm signal receipt.
✓ Passenger ferries, ro-ro vessels, and cruise ships where multi-zone fire alarm systems require reliable signal switching across large networks.
✓ Cargo vessels, tankers, and offshore support vessels operating under SOLAS Chapter II-2 fire protection requirements.
✓ Retrofit and maintenance applications aboard vessels with existing Minerva system installations requiring relay module replacement during scheduled surveys or corrective maintenance.
Why Marine Engineers Choose
The Thorn Security Minerva Alarm Relay is a manufacturer-specific component engineered to maintain the integrity of a proven fire detection platform. Its defined electrical ratings and direct compatibility with Minerva system architecture make it a dependable choice when replacing a failed or degraded relay module, minimising system downtime and supporting continued compliance with flag state and class requirements.
Ideal For
Commercial cargo vessels, passenger ships, tankers, offshore platforms, ro-ro ferries, and any vessel class operating a Thorn Security Minerva fire alarm system and requiring certified relay module replacement or system maintenance support.
Technical Support & Compliance
Remote troubleshooting guidance, commissioning support, and retrofit integration advice are available to assist engineers and superintendents working with Minerva fire alarm systems. Support can extend to onboard testing assistance, panel integration verification, and replacement scoping — subject to confirmation of system configuration and vessel details. To confirm compatibility and ensure correct supply, buyers are advised to share nameplate photographs, the full part number and code (567.007.009), panel model and software version, relevant system drawings or wiring diagrams, vessel name, IMO number, and the scope of the intended installation or replacement. All compatibility assessments are subject to confirmation based on documentation received.
