GE Security GEC-SB4U Smoke Detector Base with Sounder


Our Price : $43.00

Product Code: GEC-SB4U


This intelligent analog device uses an optical sensing chamber to detect smoke. The detector analyzes data gathered by the sensor to determine when an alarm is initiated. The detector continuously adjusts its sensitivity based on fluctuating environmental conditions such as the presence of dirt, smoke, humidity, or changes in temperature, and notifies the loop controller of any changes in sensor sensitivity.

When the detector approaches its preset sensitivity threshold, it issues a dirty sensor warning, allowing enough of a margin for maintenance personnel to clean the detector before it goes into trouble condition.

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. Sleeping rooms: In sleeping areas, the high dBA output and temporal tone settings must be used. However, if the FACP is producing the three-tone temporal evacuation signal, then the high dBA output and steady tone settings may be used.
