Sounder Bases SIGA-AB4G

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. All bases are compatible with first and second generation Signature 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.

•   Low frequency model available Code-compliant 520 Hz output. •   Temporal or steady tone Jumper selects steady or synchronized temporal output. •   High or low dB output Jumper selects low or high dBA output. •   Single or group operation Optional polarity reversing module configures base for group alarm output. •   UL268 and UL464 listed UL listing under smoke detector and audible signal standards allows application as smoke alarm and/or audible signal. •   Attractive installation Flush mount to a wide selection of North American boxes or surface mount to optional custom-matched box.
