Aritech DB952IAS 950 Series 8592dB Integrated Base Sounder with IsolatorThe DB952IAS is a range of integrated self-monitoring base sounders with integral short-circuit isolator for use on Series 950 and Series 990 systems. They incorporate a base into which a series 950 or 990 detector or beacon can be fitted. It may also be used with a red AS952CAP-R or white AS952CAP-W cap for stand-alone use.TonesThe DB952IAS sounders support multiple tones. A low tone range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only. The sounder may be set to the high range for general use.In addition to the standard tones in the DB952IAS a slow whoop tone to Dutch standard NEN2575 is available in the DB952IAS-NEN as well as a German standard DIN tone version in the DB952IAS-DIN.SynchronisationSynchronisation of tones ensures the integrity of the signaltones from different sounders do not merge into one signal that could be mistaken for a different tone. DB952IAS sounders are synchronised with each other in both alert and evacuate modes.Self-TestThe acoustic self-test means that the sounder listens to itself when it is switched on. If no sound is detected a fault signal is transmitted when the sounder is polled.The same self-test feature may also be used during commissioning or periodical maintenance testing. The sounder may simply be activated for at least 5 seconds and the control panel checked for a fault signal. If none is received the sounder is working properly.Key FeaturesTwo tone ranges 55 to 75 dB and 75 to 91 dBSynchronisation of alert and evacuate tonesIndividual sounder addressingAvailable with built-in isolatorAcoustic self-testSlow whoop option availableApollo equivalent 45681-277
