System Sensor offers relay, isolator, and sounder base options for 200 Series detectors. Relay bases provide one form C contact relay for control of auxiliary functions, such as door closure and elevator recall. Isolator bases allow loops to continue to operate under fault conditions and automatically restore when the fault is removed.

Sounder bases are available in a combination temporal 3 and continuous tone model (B200SR) or an addressable model (B200S) that can be activated by the fire alarm control panel based on the event.† 200 Series Bases provide a variety of mounting options to meet your installation challenges. Bases come in flanged or flangless versions for mounting to a variety of junction boxes. See the 200 Series Junction Box Selection Guide on the next page for junction box options. Surface mounting boxes are also available.

When used with compatible fire alarm control panels, the B200S sounder base provides unmatched flexibility to configure the output to various events. When combined with System Sensor SpectrAlert® Advance notification appliances, the B200S can serve as a UL464 compliant component of the general evacuation signaling, improving aesthetics and reducing system costs.
