The SD505-6RB adds a relay output function to an addressable detector. Providing one Form C contact rated at 8.0 amps for 240 VAC, 120 VAC and 30 VDC. The SD500-6RB allows you to control a wide variety of normally open and normally closed applications, including elevator recall, door closing, fan operation, and auxiliary notification. And, because the relay module is addressable, these applications can be located at any point in the signaling line circuit. The SD500-6RB is compact and mounts in an extension base that is compatible with the SD505-APS, SD505-AIS, or SD505-AHS. Combine this with the features you've come to expect from Silent Knight fire protection devices-easy installation and stable operation-and it adds up to a flexible solution for all your fire protection needs.

The SD505-6RB provides one Form C contact rated at 8.0 amps for 240 VAC, 120 VAC and 30 VDC. The contact can be used for virtually any normally open or normally closed application.
