Ravel RE-717 MR: Addressable Relay Module

In addressable fire alarm and building automation systems, integrating third-party equipment for automatic safety shutdown and auxiliary control is essential. The Ravel RE-717 MR is an addressable relay module engineered to provide dual dry-contact switching to control auxiliary systems such as elevators, pressurization fans, access control doors, and HVAC dampers during a fire event.

Dual Form C Potential-Free Contacts & Non-Supervised Output

The module is equipped with dual Form C potential-free (dry) relay contacts rated at 2A @ 30VDC (resistive load). These non-supervised dry contacts allow safe interface control with external building systems without injecting voltage into third-party control circuits.

Analogue Communication & Addressing

Operating over a 24 VDC nominal loop voltage, the RE-717 MR maintains analogue communication with compatible addressable fire alarm control panels (such as the Ravel AVANI, AVANI db, and AVANI XL series). On-site addressing is configured using an onboard 8-way DIP switch. An onboard red LED blinks during normal standby operation and stays illuminated solid red upon relay activation. Compact in size (95 mm x 75 mm x 24 mm), the unit features modular black construction and mounts into standard back boxes.
