Ravel RE-717 MC: Addressable Control Module

In addressable fire alarm and life safety systems, remote switching of notification and auxiliary appliances is required to trigger evacuation devices during an emergency. The Ravel RE-717 MC is an addressable control module designed to drive and supervise 24 VDC notification appliances, such as alarm bells, electronic sounders, and visual strobes.

Supervised Output Circuit & Intelligent Communication

The RE-717 MC provides a supervised Class B (Style Y) output circuit using a 47k Ohm end-of-line resistor to continuously monitor field wiring and auxiliary power for open or short fault conditions. It establishes analogue communication with compatible addressable fire alarm control panels (such as the Ravel AVANI, AVANI db, and AVANI XL series). Address configuration is easily performed on-site via an onboard 8-way DIP switch.

Low Power Consumption & Visual Status Indication

Operating from a 24 VDC nominal loop voltage, the module features an ultra-low standby current of 0.5 mA and a maximum latched alarm current draw of 2 mA. An onboard red LED provides immediate visual status: blinking red during normal standby operation and illuminating solid red when the module is activated. Compact and constructed in a modular black housing (95 mm x 75 mm x 24 mm), it mounts easily into standard back boxes.
