Overview

The Signature Series AB4G sounder bases add audible output
functions to any Signature Series detector. Bases can operate as
independent local alarms, or as part of a zone or system alarm
with synchronized audible output.
Three models provide a full range of features that meet application
needs and mandated code-compliant requirements:
SIGA-AB4G
bases provide sounder capability to Signature Series
single-function smoke detectors. They are not intended for use
with combination smoke/CO devices in Fire-plus-CO mode.
SIGA-AB4GT
bases provide sounder capability to Signature
Series single-function smoke detectors, as well as combination
smoke/CO detectors when used with a SIGA-TCDR Temporal
Pattern Generator.
SIGA-AB4G-LF
bases provide 520 Hz low frequency sounder
capability to Signature Series single-function smoke detectors, as
well as combination smoke/CO detectors in Fire-plus-CO mode
when used with a SIGA-TCDR Temporal Pattern Generator. The
SIGA-AB4G-LF is
suitable for applications requiring low frequency
audible tones.
All bases are compatible with first and second generation Signa
ture Series intelligent detectors when properly configured.
SIGA-AB4G sounder bases match the finish of Signature Series
devices, and the sound output slots complement the air entry
openings of the detector. The result is a compact unit with an at

tractive appearance.
