Edwards Signaling SB4U Audible (Sounder) Detector Base

The SB4U is designed to add an audible output function to compatible detectors. The base can operate as an independent local alarm, or as part of a zone or system alarm with synchronized audible output. Depending on the system supporting the device loop, the base can operate as follows:

• It can follow the state of the device it supports
• It can be controlled and configured for other operating modes through programming.

The SB4U is field-configurable for output tone (steady or temporal) and output volume (low dBA or high dBA). The base must be connected to a continuous voltage whether the output tone is set to steady or temporal. The base does not require a separate address because it shares the address of the device it is connected to.
